This is a superb lock that installs with little skill and is simple to program. I installed one in my daughter's home and it performed so well that I now have 3 installed in my own home.
I recommend it to anyone who needs a secure dead bolt that can be programed for multiply users with different codes as well as a once access for someone who does not need regular access.
ALL IN ALL IT IS A GREAT LOCK [This review was collected as part of a promotion.]
