Rated 5 out of 5 by from Great Item Had to replace the locks on my porch and front door as had lost a set of keys Didn't need to replace the whole night latch as it still worked therefore brought just the cylinder to save some money Easy to install - had to trim the mechanism with a hack saw but has an easy guide on it to assist with this All in all a great item at a great price
