Review: No complaints here - has been great.
Review: Good lock for the money. Replaced an old lock with this new one. The lock fitted in the door without any modification to the wood. The other metal part the lock turns into was bigger than the old one so the door frame needed chisling out a little bigger. Basically just a few mm along the top and down one side so the plate would sit in flush as it is slightly taller and wider than the old plate it replaced. It came with 2 keyhole covers and some screws. The big screws I replaced with some bigger ones with stronger heads as the supplied screws rounded out on me as I didn't have a drill. I used bigger and longer screws for better strength. You really should have a mortice lock on a door if you only have a Yale type lock then I suggest you should get a mortice lock if you don't have one. Yale locks can be broken into far too easily in a few ways. A mortice lock is a lot more secure and stronger. For the money it's a really solid lock. You'd have to break the whole door down to get in now. I would also advise to have half decent chisel and a hammer so you can do a neat job of fitting it. It's not hard to do. Easy with a sharp chisel say about a 1" width will do just so you can fit the side plate on. If it's the same size as the old plate then you can do a straight swap or just leave the old plate fitted. The lock fitted solidly and my door is very solid and secure now. If fitting from scratch you'll obviously need all the proper tools or a lock smith or carpenter to do it for you. It arrived quickly in only a few days time. I ordered from Richards Builders Merchants based in the UK here on desertcart UK. I choose these as it was the best price and I did not use Prime. The item was new, boxed, complete and it came supplied with 2 keys.

*by J***N on January 20, 2024*

These are very substantial locks, with a good key action and they're very easy to install. I used a 22mm wood drill (Bosch Pro range, as for sale on Amazon) and got the frame and door apertures cut quickly. The lock itself comes with a front cover plate so you don't actually see the red body paint when installed, just a bright chrome plate which matches the one you fit to the door frame. A very smooth key-turn action, and the bolt has a LONG travel that means it goes into the door frame a long way. The lock comes with a keyhole plate for the inside of the door, and a covered key plate for the outer door face to keep the rain out. The lock has an extra quarter-turn at each end to retain the keys in the lock in either direction. The screws supplied for the lock and frame plate are also substantial. Nice and long, with a large diameter but they didn't split the wood in the frame or door when I installed them. They seem to go in really tight, adding to the impression that you've purchased a very high security lock. It's got to be 5 stars for how substantial this unit is, how easy it is to fit, how smooth the lock action is and the overall impression of added security you're getting.
