Door won't open
uPVC door won't open? Three checks before you force anything.
Wolverhampton, Stafford and Cannock. Honest diagnosis: gearbox, spindle, cylinder or a dropped door.
If your uPVC or composite door has stopped opening, the cause is almost always one of four things: the multi-point gearbox has jammed with the hooks stuck out, the handle spindle has snapped, the cylinder has seized, or the door slab has dropped and is binding in the frame. The good news is most jammed doors can be opened without any damage, and forcing them is the one thing that turns a cheap fix into an expensive one. The honest reason a national locksmith number jumps straight to "new lock" is that it is the highest-margin job. Read the three checks below first. If you still need me, ring direct and the all-in price is quoted on the phone before I leave the van.

uPVC door won't open? Three checks before you force anything
Before you shoulder the door or reach for a screwdriver, run these three checks. The first one alone opens about one "stuck" door in five with no tools and no cost. The other two tell me on the phone exactly which part has failed, so the price I quote is the price you pay.
-
Lift the handle fully, turn the key both ways, then push AND pull
Before you decide the door is broken, lift the handle right up to the top, try the key a full turn each way, and try both pushing and pulling the door. A multi-point that is only part-thrown will sometimes release with the handle fully up and a firm pull. About one "stuck" door in five opens on the doorstep with this single move and costs nothing.
-
Take the key out and try the handle on its own
With no key in, work the handle up and down. If it moves but the door stays shut, the gearbox is driving nothing (the points are jammed out, or the follower has stripped). If the handle flops with no resistance at all, the spindle or follower has snapped. If the handle is solid but the key would not turn a moment ago, the cylinder is the problem. This ten-second test tells me on the phone whether I am bringing a gearbox, a spindle set, or a cylinder.
-
Look at the door edge: are the hooks still sticking out?
If you can see the gap down the opening edge of the door (through the frame, or the letterbox on a part-open door), look for the steel hooks and bolts. If they are still poking out of the door edge and will not pull back in when you drop the handle, the gearbox has jammed in the locked position. That is the single most common reason a uPVC door will not open, and it is a clean replacement, not a forced entry.
Is it the gearbox, the spindle, the cylinder, or the frame?
Match your symptom to one of the four branches below. The branch tells you what has almost certainly failed, what fixing it costs, and how long it takes. Two of the four are cheap fixes that a national number will quietly turn into a full lock change, so it is worth knowing which one you are looking at before you ring anyone.
-
If the key turns fine but the handle does nothing and the door stays shut...
The multi-point gearbox has jammed with the locking points thrown OUT into the frame. The key is retracting the deadbolt, but the hooks and rollers the handle drives are stuck and will not pull back in. This is the most common door-won't-open fault I get called to. A like-for-like gearbox replacement is from £145, and I can usually release the door non-destructively first so you are back in before I even fit the new part. Do not force it: a jammed gearbox is a £145 fix, a sheared follower from forcing it is closer to £250.
-
If the handle spins or flops with no resistance and the door will not open...
The square spindle that links the inside and outside handles has snapped, or the gearbox follower it turns has rounded off. If it is just the spindle and handle set, that is a cheap, quick fix well under the price of a gearbox. If the follower inside the gearbox has stripped, the gearbox itself is replaced from £145. I carry both spindles and gearboxes on the van so it is one trip either way.
-
If the key will not turn at all and the handle is otherwise fine...
The cylinder has seized, or you are turning a worn key that has finally given up. Try a puff of graphite or a dry PTFE lubricant in the keyway first (never oil, which gums up). If the key still will not turn, the cylinder is changed from £90, a 20-minute job, and the gearbox and door are untouched. The full diagnostic for a key that will not turn is on the dedicated key-won't-turn page.
-
If the door unlocks fine (handle lifts, key turns, points retract) but the slab still will not pull open...
The lock is doing its job: the slab itself is binding in the frame. The door has dropped on its hinges, or swollen after a wet spell, so it is wedged tight. A long hex key in the 3D hinge adjustment screw usually brings it back into line in 10 to 15 minutes, from £90 and often no new parts at all. The same dropped-door mechanics, seen from the locking side, are covered on the door-won't-lock page.
What national locksmith numbers will not tell you
A uPVC door that will not open can almost always be opened without damage by a locksmith who knows the mechanism, even when the gearbox has failed. Drilling and "new lock" should be the last resort, not the opening quote. I would rather release your door non-destructively, get you in, and then fit the right part calmly than turn up, drill it, and bill you for a job that never needed doing. An honest fix that leads to a word-of-mouth recommendation beats a panic sale every time.
When the door unlocks but the slab still won't open
This one catches a lot of people out. The lock is working perfectly: the handle lifts, the key turns, the points pull in. But the door slab still will not pull open without a real heave, and it often jams again on closing. That is not a lock fault at all. The slab has dropped a few millimetres on its hinges, or swollen slightly after a wet spell, so it is wedged in the frame.
Two visual cues. One, look at the gap between the slab and the frame at the top compared with the bottom: if one is touching and the other has a clear gap, the door has dropped. Two, look at the latch corner for any sag, and the threshold for a fresh scuff or wear mark where the slab has been catching. Most uPVC butt hinges have a 3D adjustment screw behind a small cap, and a long hex key turning that screw a quarter-turn at a time usually brings the slab back into line in 10 to 15 minutes. No new lock, no new parts.
Locked inside and the door won't open? Read this first
If anyone is at immediate risk, or there is a fire, ring 999 first. The fire service will force entry and a damaged door is a price worth paying for someone's safety. Do not weigh that up: make the call.
If it is not an emergency and you simply cannot get out of a uPVC door from the inside, do the calm thing before you break anything. Lift the handle fully and turn the thumbturn or key the opposite way, because a part-thrown multi-point is the usual reason a door will not release from inside. If it still will not open, ring me and tell me you are locked in: I treat being trapped inside as a priority call and head straight there. Most "locked in" uPVC doors are a jammed gearbox that I can open with no damage at all, so please do not put a window through unless someone is genuinely in danger.

Mr Aaron K., Wolverhampton
Whole family home from a day out, key turned in the front door but the handle was dead and the door would not budge. White composite door, Fullex gearbox, hooks visibly stuck out of the door edge. They had been heaving on the handle for ten minutes before they rang.
A national number quoted the customer £360 OOHPaid to me £230Out-of-hours call. Released the jammed multi-point non-destructively in about fifteen minutes so they were straight back in, then fitted a like-for-like Fullex gearbox once everyone was warm inside. No damage to the door or frame. Tested it ten times open and locked from both sides before I left.

Mrs Pauline H., Stafford
Back door handle had gone completely floppy overnight and the door would not open. No resistance in the handle at all, key fine. Eight-year-old uPVC door. She was convinced she needed a whole new lock and had been quoted for one over the phone.
A national number quoted the customer £175Paid to me £75Snapped split spindle, that was all. The gearbox and cylinder were both fine. New spindle and a matching handle set fitted in under twenty minutes. Showed her the snapped spindle so she could see it was never a lock-change job. The kind of £75 fix a national number sells as a £175 lock replacement.

Mr Gurpreet S., Cannock
Front door unlocked perfectly (handle up, key turned, points pulled in) but the slab would not pull open without a real heave, then jammed again on closing. Followed a week of heavy rain. Twelve-year-old composite door, lower hinge slightly rusted.
A national number quoted the customer £195Paid to me £90Door had dropped about 3mm at the latch corner and swollen a touch in the damp, so the slab was binding on the frame. Long hex key into the lower hinge 3D screw brought it back into line, eased the keeps, and it opened and closed cleanly. Fifteen minutes, no new parts, no new lock.
uPVC doors that will not open or shut are covered in the Master Locksmiths Association's consumer advice, which notes that a door slightly out of alignment causes problems both locking and unlocking, and that multi-point systems have several moving parts that can jam. The multi-point mechanism and the euro cylinder behind your handle are covered by the door-hardware standards set out by Secured by Design, the official UK police security initiative, which is also why forcing a jammed door (and snapping the cylinder in the process) is the expensive mistake to avoid. My from-prices for the work above start at £90 for a doorstep alignment visit and £145 for a like-for-like gearbox replacement.

Verified Google reviews from real customers across Wolverhampton, Stafford, Cannock and the surrounding villages.
I contacted Sean in a panic after our back door wouldn’t lock at 21:15 on a Sunday night. Sean came back with a price almost immediately and offered to come and look at it straightaway. At my request, I asked him to come Monday morning and he sent me an ETA and turned up bang on time. Sean quickly diagnosed the problem, he had to go off to get a a part and when he was on his way back to me, he even shared his location via WhatsApp so I knew when he would be back. Part fitted, worksite cleaned up and he was on his way. Reasonably priced, fantastic communication from start to finish and a great bloke to speak too as well. Thanks Sean, you’re an absolute star!
Absolute pleasure meeting you and your wife today in Codsall / Wolverhampton. I'm really pleased I was able to repair your faulty upvc door mechanism. Thankyou for the glowing review....it's really appreciated. Sean - Lockerfella Locksmiths 24/7

It was an absolute pleasure helping you today Saeideh in Wolverhampton. Thankyou so much for the kind words. Sean - Lockerfella Locksmiths 24/7.
I locked myself out my house and phoned Sean at 1.32am. He arrived at my house in Bilston 35 minutes later. He lives 30 minutes away. He was very professional and tidy. I would recommend him to anyone. Within 1 hr and 15 minutes of calling him he had come out, sorted my lock and on his way home. You can call him anytime and he will get to you asap. Worthy of the 5 star rating
Thankyou for your review Shell. Real pleasure to assist you both with your emergency call-out. Sean - Lockerfella Locksmiths 24/7
Sean came out for an emergency call out at 2am due to a lock malfunction on the front door. He was responsive from the first point of the phone call and was clear with what he was able to do and provided an accurate timescale and live location When sean arrived he felt like someone who was a safe person and as a lone female that felt important when I couldn’t get in my home in the early hours. He’s was patient and thoughtful with my dogs who were trapped inside. He was friendly, calming and reliable. Would highly recommend him
Thankyou for your review, it means so much. I'm so glad I could help you this morning in Stafford with the emergency call out. Have a great day to you and the doggies 🐕. Sean - Lockerfella Locksmiths 24/7
I run a letting agency in Wolverhampton and unfortunately had a tenant whose UPVC locking system had collapsed locking them into the flat unfortunately during the football match between England and Croatia in the 2026 World Cup. As you can imagine, I was having a bit of trouble getting a locksmith! At least until Sean contacted me. He went out very quickly, opened the door and replaced the gearbox working from 11 pm until 2 am so not very sociable hours. Given that I thought the cost was very reasonable and the service was excellent. I will certainly be using Sean again and I cannot recommend him highly enough. The world of emergency locksmiths can be a murky one at times so it is really nice to have someone you can trust to call on.
Thankyou so much Andy. It wss my absolute pleasure. 😊
Phoned this lovely man this morning before 8am , it's now 11.28 am and my lock is fixed , thank you Sean , as I live alone i was feeling vulnerable, thank you so much , fir your prompt response
Thankyou so much for your review Maureen. Real pleasure assisting you today in Walsall to replace your Euro Cylinder and Door handles. Sean ☺️
Absolutely brilliant service from Lockerfella Locksmiths. We left Sean a whatsapp message at 2.30am as we had stupidly left our front door keys inside when leaving the house. He answered pretty much immediately. Sean arrived with us in Stafford within 30 minutes and had us back in within 5 minutes and fitted us with some upgraded anti snap locks. Thankyou!
You're more than welcome Matt 😊
I was locked out of the house so gave Lockerfella a message. Sean was incredibly swift in his initial response, giving an ETA and an estimate cost at the same time. I immediately booked in with Sean and he came as arranged, tried his best to pick the lock, however it wasn’t to be so he changed the lock and was all done and dusted in a reasonable time. He was polite, prompt and professional. I would recommend anyone needing a locksmith to contact Lockerfella
Thankyou so much James. It was a pleasure to assist you in cannock that day with your emergency locksmith call-out.

Common questions about doors that won't open
Straight answers about why a uPVC door jams shut, gearbox vs spindle vs cylinder vs a binding slab, what each fix costs, and what to do if you are locked inside.
Why won't my uPVC door open from the outside?
Four causes account for nearly every uPVC door that has stopped opening. One: the multi-point gearbox has failed with the hooks and bolts stuck OUT in the locked position, so the points are jammed into the frame and the door is held shut. Two: the square spindle that links the inside and outside handles has snapped or the gearbox follower it turns has stripped, so the handle moves but nothing happens. Three: the cylinder has seized and the key will not turn. Four: the door actually unlocks fine, but the slab has dropped on its hinges or swollen in damp weather and is wedged tight in the frame. The Master Locksmiths Association notes that a door slightly out of alignment causes problems both locking and unlocking. The fix and the price depend on which of the four it is, which is why I work it out from your symptoms on the phone before I set off.
My key turns but the door still won't open. What's wrong?
If the key turns the full way round but the handle does nothing and the door stays shut, the multi-point gearbox has almost certainly jammed with the locking points thrown out. The key is retracting the deadbolt, but the hooks and rollers driven by the handle are stuck in the frame and will not pull back in. This is the single most common reason a uPVC door will not open. Do not keep forcing the handle: a jammed gearbox is a like-for-like replacement from £145, but forcing it can shear the follower and the lock body and push the job past £250. Ring me with the symptom and I will bring the right gearbox.
The handle spins round loosely and the door won't open. What is it?
A handle that flops or spins with no resistance, while the door stays shut, almost always means the square spindle between the two handles has snapped, or the gearbox follower (the square hole the spindle turns) has stripped. If it is just the spindle and handle set, that is a cheap fix, often well under the price of a gearbox. If the follower inside the gearbox has rounded off, the gearbox itself needs replacing from £145. I can usually tell which it is from a ten-second description on the phone (does the handle have any bite at all, or is it completely free), and I carry both spindles and gearboxes on the van so it is one trip either way.
Can I force a uPVC door open if it's jammed?
I would strongly advise against it. The instinct is to shoulder-barge a jammed uPVC door or lever it with a screwdriver, but if the cause is a gearbox stuck in the locked position you can shear the follower, bend the lock body, crack the door slab, or split the frame, and turn a £145 gearbox swap into a full door repair. The exception is a genuine emergency where someone is at risk inside (see the question below). For everything else, the honest move is to stop, ring me, and let me open it non-destructively or replace the failed part cleanly. Nine times out of ten the door, the frame and the keys all survive.
I'm locked inside and the door won't open. What should I do?
If anyone is at immediate risk, or there is a fire, ring 999 first: the fire service will force entry and a damaged door is a price worth paying for safety. If it is not an emergency but you simply cannot get out of a uPVC door from the inside, check the obvious first: lift the handle fully and turn the thumbturn or key the opposite way, because a part-thrown multi-point is the usual culprit. If the door still will not release, ring me and tell me you are locked in. I treat being trapped inside as a priority call and prioritise the route there. Do not break a window unless someone is genuinely in danger, because most "locked in" uPVC doors are a jammed gearbox I can open without any damage.
How much does it cost to fix a uPVC door that won't open?
It depends which of the four faults you have. A door that has simply dropped or swollen and is binding in the frame is an alignment job from £90, often no new parts at all. A snapped spindle and handle set is a cheap fix at the lower end. A jammed or failed multi-point gearbox is a like-for-like replacement from £145. A seized cylinder that has to be changed is from £90. Out-of-hours (6pm to 8am, weekends, bank holidays) attendance is from £170. There is no call-out fee and no VAT on top, and I quote the all-in figure on the phone before I leave the van.
How long does it take to get a jammed uPVC door open?
Opening the door itself is usually quick: a jammed multi-point can often be released non-destructively in 10 to 20 minutes once I am on the doorstep, without damaging the door. If a part has failed, the repair adds time on top: a gearbox replacement is 40 minutes to an hour, a spindle and handle set is 15 to 20 minutes, a cylinder change is 20 minutes, and an alignment fix is usually 10 to 15 minutes. I test the door several times opening and closing from both sides with your own keys before I take payment, so you are not left with a door that jams again the next morning.
