We were looking for an electronic lock that doesn’t to rely on wi-fi or a phone app as we have had issues with others in the past, the 915 Smartcode Electronic Deadbolt was just what we were looking for. It is easy to install, took about 30 minutes. It takes 4 AA batteries, according to the manual they should last at least a year! It was very easy to setup the codes. The deadbolt can be opened either with the keypad or a key and 2 keys are supplied, but as we are a family of 3 the fact that you can rekey the lock quickly yourself meant we didn’t need to change keys. Keypad entry is quick and easy with the code and locking can be done with one touch or you can enter/exit with the keys. The satin nickel lock and keypad are a stylish modern design that looks great on our door.
