Many thanks for posting this … very useful and a big thumbs up from me! 👍 I had the same problem and took the gearbox apart to find at least two broken internal parts! I ordered a replacement and refitted back together … success! Thanks again 🙏

Wow. So refreshing seeing a proper diy vid where the creator ISNT trying to make it all about them or their business/service! To the point and education. Thanks. 👍

Good one ! Ithanks , I expect those PINS take a real beating over the years ,,, thanks for digging so deep on this !!, great info

Thanks for uploading this. My UPVC door locking mechanism stopped working today. Replaced the central part from local locksmith. Only problem I had was, I found out which lock it was from google, rang local shop who said they had it in stock. When I got to the shop, they asked is it the smaller deadlock or larger, of course i didn’t take the faulty one with me, and of course I had the cheaper one. Wrong. So back again to get the smaller one, but more expensive. Moral of the story is always take the old one for comparing. Still cost me just under £50, and job satisfaction.

Thank you Mr Khan. I was about to buy a whole new lock, now I understand I just need to change the gearbox.

Thank you very much for posting this. I just replaced mone today. If it weren't for this, i would have been down atleast £150 if i had to call a locksmith. Brilliant and thanks again.

A thank you from me. I looked at a lot of videos to research the problem I was having. Your video was a superb assistance in diagnosis and replacement of the gearbox, which now closes and locks like a Mercedes door. 👌

Very clear and precise video. Going to hopefully do the same with my patio door. Thank you

Straight to the point no messing about 👍

Video So good Mr khan , no messing about, no music ,easy to follow 👍🏻

Thank you Sir for this video - bought a new lock for £45 - SAVED ME £180 ! WELL DONE MATE

Masha'Allah very good lesson 👌

That's really good clear info

I like this very much for the content and the fact that you showed that it doesn't always go smoothly but by perseverance, it can still be done...Thanks

Chah gia Punjabi Puttar.😘

really good video,, enjoyed that, often wondered what was inside one of these locks,, I d happily replace one of those now myself thank you. Brilliant job

54 lbs vs. a tiny tiny screw, now a day they don’t make anything to last, obsolescence!

you've just saved me a lot of expense, thank you very much for posting.

Great job, tomorrow i will try to fix the same problem on my door. A big thank you.

First time I ever seen this go wrong,,,,,,great job

I've got that same door lock. Glad this video has helped. Fingers crossed it will work properly

Brilliant job Khanie, you have probably saved many of us a good few bob. i'm gonna subscribe :-)

Really useful and helpful video - many thanks

Great video fella - I'm off to buy the required part!

Cheers great info, thanks for sharing I am just off to my daughters house to a problem door lock.👍

Been looking everywhere for this video, I have the same problem but it locks fine just won't open again, thanks

Thank you so much , very helpful video 👍

Thank you for this video

Great video! Very helpful thanks 👍

Nice one , thanks

Excellent tutorial but I would add one word of caution. The screws which retain the locking strip into the edge of the door are self tapping and screw directly into the PVC. It is important to get these screws very straight as if they are only slightly off centre they can foul the sliding mechanism.

Great job.

excellent video. I was wondering what was behind that moving plate. You look like you re a pro and used to these upvc locks

Really helpful video. May I suggest you change that euro cylinder lock for a anti snap one.

Cheers .... that's my exact issue ....🎉🎉

It may be worth checking Amazon as a replacement gearbox for most models can be had for less than 20 quid.

Thank you sir for the video great job

Many thanks.

Really helpful., thanks. Have the same problem !

Thank you for this

good video helpful

Good job.....

Hi my key Jammed one side door but can use key other side door and lock unlock fine any ideas. Was a sudden seizure door had been working fine. I tried a little oil didn’t help

Hi very nice informative video. i have a similar issue but with the lock part that comes out into the door frame side after turning key to lock the door . On inspection , the slot (vertical -rectangular in shape)inner edge which seems to contain an inner layer of some material has bent forwards into the cavity , preventing /blocking the latch part that moves into slot with key is turned to lock the door. Any possible solutions for this . Many thanks.

Good job, but I couldn't watch you using the power screwdriver when screwing things back, you can very easily strip these plastic threads. I'm up for the same job, will do everything manually, plus will lube the screws before putting them back in just in case.

My mother has a problem opening her front door. She has to yank down on the handle A few times until the door opens, it’s a upvc door. What would it likely be?

When you put the barrel back in the door I didn't see you putting the screw in that holds the barrel in place. Did you forget to put it back in or did you forget to film it?

Great video mate, thanks

Thank you for this vid 👍

I have a 3 way locking mechanism would the whole mechanism need replacing ? Its a safeware 3 point lock hook latch type

So useful many thanks 👍

My lock gets stuck, I have to pull it out with pliers so thinking of doing what you did..what was the company in Oxford you used as I’m not far from Oxford. Great video as well 👍🏻

Sounds like that’s my problem. Trip to the locksmith on the cards for me.

Amazing hack 💖💖

Thanks a lot dude!

DId you buy the same gearbox as the old one or any gearbox will work?

my door handles are the same but they don't come off when removing the screw's. I think they have an extra security or internal screw? any help?

Great video! My door has the opposite problem which is not unlocking /opening the door with the key..could this be a problem with the mechanism or the barrel? Thanks

Good job!

I think for that price, I may as well put in a deadlock key system. Seems cheaper than the price u said. Maybe that's what happened with my front door.

My wife would have hit the roof with the way this man threw the handles etc onto that table.

The barrell didn't come out after unscrewing that one screw. Do you have to unscrew the others for it to come out?

Wow❤

informative

Where do you get new gearbox from.

Is the locking mechanism you replaced universal for all UPVC doors?

Which screws did u open star screws or 4 way screws

Old style gear box mechanism doesn't have screw, how to open them?

How can I open euro cylinder without damaging it. It's a new cylinder. But won't unlock door as the gearbox is broke. I snapped the 1st cylinder, to open door. I fitted new cylinder. And customer locked it without my say , so now I'm back to square 1.. Can I open without any damage.? What about the little latches on gearbox? Can't I flick a latch on the gearbox to open door?
