The lock supplied with 2 keys. Spare key will cost you at least £10 per duplicate. Beware!!Normal key cut is 3 for £10 from Homebase and The Range. Their cutting machine is Mykey. The machine will not not recognise as it is Patented key. See photo.Timpson want to charge £10 per key. As I need 2 more spares, this will cost even more.Don't buy these locks if you need more spare keys. This will be returned for refund.Amazon need to spell out that the key supplied is Patented means you can get it cut anywhere, only specialist place and will charge at a extortionate rate.

Made from cast bronze, this lock is very solid - you know it's going to protect your door. Fitting it is simple - in my case I was replacing a different lock, so didn't have to create the mortices. I offered up the template, drilled 4 holes in the right place, screwed on the back-plate, then positioned the strike plate on the door frame (I did have to enlarge the mortice for this, but no big issue. After cutting the new cylinder rod to fit, I fitted the cylinder, then used the two stubby brass screws to attach the main body. In use you can feel the weight of the mechanism and it certainly feels solid, secure and high quality. You can deadlock the inner latch using the key, which prevents it being opened from the inside. In addition, it has a strike-plate deadbolt - when the door is closed, it's not possible to shim the latch using a thin, flexible piece of plastic or metal. Superb.

I bought this lock to replace a lock of the same model which had lasted thirty years. The new lock was exactly the same dimensionally, so was a very easy fit to my door. If starting from scratch you will need some DIY skill or call in a handyman. The lock comes in dark grey (not brass as shown), so is unobtrusive on the door. All parts are heavy and the supplied screws are of good quality. The big advantage of the lock is that you can turn your key on the inside handle before closing the door, and then it is deadlocked, and can't be opened even if some one were to punch through the door panel or glass.This size of lock will fit the frame of a glazed door, so you should end up with a neat, secure lock. Why not 5 stars? Well, it feels a little sticky when I turn the key, and I hope that when the key wears a bit, the action will be smoother.

Purchased to replace an existing P2 lock which had been faultless for over 20 years, unfortunately we recently locked our keys inside and couldn’t gain entry to our property, a locksmith was called and it took him the best part of an hour to get the door open, even after drilling out the barrel the lock was reluctant to admit defeat, these locks are brilliant, just don’t forget your keys!

I received the original product which was returned because the finish was grey and not polished brass as shown on the web site. The replacement was also grey even though Amazon were informed of the original problem. This is to be returned for a full refund.If you want a Polished Brass finish don't go for this one!!!!!
