Yale PM562 High Security BS 5 Lever Mortice Dead Lock 76mm 3-inch - Polished Brass Finish - 2 Keys included

This was to replace a 20 + years '5 Lever Mortice Deadlock' and not much had changed in that time as far as design principles, but the dimensions and keyhole layout geometry were different in my case and this meant akward labour, if like me you're not a experienced fitter. Great kit (every thing you need ...screws, inside /outside keyhole escutcheons, template, lock and lockbox), although the lockbox seemed oversize, it agreed with the "NEW DOOR" instalation guide yale seem to have supplied (a list of the kit parts is not included ,you work out what you have is correct or not by the fitting guide and the parts you are replacing being like for like-ish .The length of lockbox slot=50mm yet the mortice lockbar is about 35mm (like a small foot in a large shoe) .. so the lockbox seemed to be universal and probably the same one is supplied with both the 67 mm and 80 mm door lock kits .Like for like installation ..newer doorlock replacements maybe would just slide straight in and the diementions be a better match than mine.. like shown in the helpful video 'yale' have made to show the general install (don't expect to walk away as clean clothed as the young lady or man though) .Tools i found myself using were ... philips head screw driver ,chisel and drill .My twenty year door lock i replaced is a 2.5 inch (67 mm) lock ,the replacement is also 67mm but needed an extra 12.5 mm depth ,for this next gen lock to be able to slide fully into the door frame and the keyhole is now 7 to 10 mm lower and further toward the centre of the door by 4mm ,also both sides of the new lock have a rectangular metal plates welded in place over the lock mechanism ,for added lock tamper proof protection i believe ,which required chesil woodwork to shoehorn this extra clearance and allow the lock into the door slot .Many many hours later and wood shaving all cleared away ,all the new parts fitted + screwed inplace i'm finnished .Hmm the new lock feels smooth and has slick pricise bolt throw as the as the key is turned .A SATISFYING JOB DONE ,A GOOD PURCHASE .

After installation the lock didn’t work, broke a key and then the other bent trying to open the lock. Now have to remove and install another. Do yourself a favour and avoid at all cost.

Very good lock,well made with a good finish Worth buying

For an American who loves locksport, it's very nice to be able to affordably get these locks. Excellently made, good challenge. And delivered to me early (your mileage may vary).

Very sturdy and secure lock. Brilliant quality and good price.
