    Golden Review Award: 6 From Our UsersMy daughter had just moved into a new house and the lock was showing all the classic signs of age-related failure, so I need to replace it. Locksmiths prices are silly, so with some trepidation I decided to have a go myself. It turned out to be very easy to fit, was suitable for the door and after a bit of tweaking (using the Yale video available on YouTube) it now works perfectly. Very impressed.

    The item was as described and easy to fit. Making it function properly required some time.

    Golden Review Award: 6 From Our UsersI had a problem with one of my double glazed doors. It was stiff to turn the handle up to lock the door. I removed the locking mechanism and opened it and the two hooks at the top and bottom were knackered. I purchased this in the 35mm version . It wasn’t too difficult to fit. The instructions were not very clear. I had to read it a couple of times. There is a video online to show how to fit it apparently. It did the job. Door now closing exactly as it should be. Recommended product. Make sure you get the right size.

    Used this lock unit to replace very old existing lock on front door. Took a few hours to install but satisfactory product when completed. Hope it lasts as long as the old lock. Recommend that the lock unit is installed by someone who is experienced in DIY.

    Golden Review Award: 3 From Our UsersArrived on time with Yale packaging, fitting the lock gearbox was straight forward, reversing the latch was easy, reversing the night latch was a bit tricky, the instructions is not very clear, but i managed to do it at the end.
    Only problem i have is that the gearbox doesn’t lock from outside, it locks from inside without problems, but from outside it doesn’t lock with the key, i will try to contact the seller.
    Youtube video that shows the installation is missing some details, like reversing the night latch
    Update: I have changed the lock cylinder and this seems was the problem, it locks perfect from outside and inside without any problems

    Fitted in about 20 mins but took anothe 20 mins doing ‘minor ‘adjustments to the keep, which is what I expected. Overall a great product and saved me a lot of time trying to find original replaceme

    This item replced my existing broken mechanism. It was simple to fit to the door in a few minutes and then a little time was spent adjusting it to get it working right.
    End result was it worked better then the original one ever did and the whole job from start to finishe took less than an hour.

    Golden Review Award: 3 From Our UsersTried for weeks to find a replacement gearbox for a discontinued roto lock both online and with a locksmith.
    Came upon this product which matched all the dimensions etc. Delivered and fitted within 2 hours at a massive
    saving over getting someone in or replacing the french doors. Had to fiddle with fitting the latch plate due to the
    width of the door and found that removing the mushroom / roller keep plates and fitting and adjusting them one
    at a time helped.
    Cannot comment on longevity yet but being Yale and coming with a 10 year guarantee can’t envisage any issues.

    Perfect. Tried changing just the handle gearbox but couldn’t get one to fit my existing door strip so I bit the bullet and bought this product and with the help of a couple of You Tube videos managed to fit it with out too much trouble.

    Superb door lock, no need to get a new door when you have this to buy.

    Very good replacement lock. Top end security. A bit fiddly to fit and adjust.

    A good replacement lock. This was used to replace the broken mechanism on a set of double upcv doors, everything is working fine, but need need a decent amount of adjustment to lock correctly (not to be blamed on the lock)

    Initial impressions not great from the packaging – something that should probably be improved (all parts there, but barely given the damage to the box).

    Instructions mostly good. Worth following. If using with upc doors, you may also need to adjust the hinges themselves on the door to get a good fit. e.g. You might notice the door closes, but you can’t lock the handle – the door might need moving towards the keep. I also needed to do a bit of adjustment with a saw to let the main latch go into the frame.

    This was just the job. Instructions were clear, and the unit fitted into my uPVC door a treat.

    Very easy to fit and works like a dream – just what I needed. I’d been putting off doing it for ages living with a door I couldnylock and my dog could open and let himself out. Should have ordered this lock about a year ago. Very satisfied.

    Bought this to repair my tenants door. Arrived on time and good quality. Unfortunately it was just slightly the wrong size which was not the fault of the manufacturer, it’s just there are loads of different types and makes. I returned it with no problems at all and was very pleased with the service and would not hesitate to use this company again.

    Ottima serratura , attenzione per alla profondit , non molta e su alcuni tipi di porta potrebbe non essere corretta

    Friend bought a pvcu door from a well known DIY retailer but the multipoint locking mechanism provided with the door was poor quality. Purchased this to replace it, easy to fit, good instructions, all necessary accessories provided. Took under an hour to complete changeover.

    Super easy to install having removed a very old/worn locking mechanism. Didn’t even follow the instructions, simply cut down the sections for the top/bottom hook mechs, offered up to the door and screwed into place. Door jambs needed minimal adjustment and existing frame holes required minimal elongation to accept top/bottom hooks. All in, took about forty five minutes to install.

    Fitted this to my front UPVC door as existing had failed. Pretty straight forward instruction with plenty of fixing screws. I had some snagging on the keep when the rollers tried to run in the locking channels. I removed all “4” keep channels and refitted one at a time and adjusted individually to suite until all working correctly. Would definitely order this product again. Fast delivery also from the company.
