I got this kwikse 980 Deadbolt - Keyed One love these locks. I have several rental properties and I've started using these on all the main doors (I use the 980's on other doors). Very easy to install and I have not had any problems. highly recommend you get a reset cradle in case you lose your key because you must have a working key to reset the top or bottom locks. Search youtube and learn how to use it because you will eventually need it. Great quality brand thanks
