Great study lock at a great price, was purchased for a bedroom door always known era to be of good quality and standing I myself installed the lock and being competent with my hands being a handy man I found the install straight forward and easy with fairly minimal tools (combi drill a rattler a sharp chisel couple of spade bits and the relevant marking implements a pencil tape square etc ) the lock looks tidy and smart and comes with a few spare keys 10/10 from me does the job and looks well hope this review helps :)

Very good lock, installed very easily. Comes with 2 keys, but we need 4, and was very surprised when the 2 extra keys cost more than the lock itself ! In our local town, or online, the cost was about the same.
