Absolutely terrible experience with Kastle Systems. The mobile access app is unreliable and frequently does not work at all. I’ve been locked out of my own building countless times because the app fails to unlock doors when it should.
I’ve contacted support over and over again. Each time, a technician eventually shows up, has no idea how to fix the issue, says they’ll “escalate it”… and then nothing happens. No follow-up, no fix, no communication. The exact same problem keeps happening.
This is an access control system. Reliability is the entire point. If I can’t count on it to let me into my own building, it’s a complete failure. Avoid if you have any choice.
