Have anyone gone Keyless

[Tim Huynh]

I'm tired of changing out my keys or rekeying.  I'm considering going keyless and changing all my deadbolts  (each one is roughly $55).  A concern would be that the batteries would be dead forcing my tenants to be locked out.  However, I have 3 doors for entry to the house so I don't seeing all batteries being dead at once.  Have anyone did this as I would love to hear your feedback on this?
