Keyless Door Access What Is The Best Door Security With Room Renters?

What is the best door security with room renters? - keyless door access

I rent rooms in a property that I have and find a headache, or change the lock code or security in the garage every time a tenant moves.

I saw some of the locks on the door unlocked using fingerprint technology to enable access at home. I have the idea now, but wondered if anyone has any experience with these or should offer a different proposal.
