I have about 30 digital locks on my various properties.
I bought a Schlage that did not have a key as a backup - it was $129. For me, a key hole makes the lock less secure as it is easy to pick.
Anyway, I wasn't brave enough to try it on a condo or any property with just one door.
So I put it on the garage entry door on a single family. The main door has a digital lock with a key backup.
Sure enough, the Schlage died after 18 months. It is a non-motorized deadbolt type.
So I call up Schlage. They agreed to send me out a new one. In talking to the Rep I asked how they can sell something that is not very reliable. I explained that I have 30 digital lock - some 8 years old - and none have failed. Incredibly, the Rep said that the 1% failure rate on the lock was low.
I asked him if he would be OK with him not being able to get into his house 3 or 4 times a year? And each time you had to call a lock smith. He got the point.
Incredibly, Schlage's policy is that if you get locked out of your house you can call them and they will send over a locksmith to tear the digital lock off the door.
Even more incredible is that it takes them 2 or 3 weeks to send out the replacement (in this day and age?).
Hold on! The story is not over. In August I got the replacement Schlage lock. I installed it on the same door. Well, it stopped working. Same isue. That is only 3.5 months. So now I have to call them back up and see what they want to do with their POJ.
