Thanks for your reply-
This sounds like my first opportunity to delve into the door handle lock/alarm combination...
Do you have any idea how the alarm is integrated with the door handle lock? Does it seem feasible that the alarm enabling/disabling would be okay while the actual moving of hardware (disengaging the door's lock) would fail? Another way of saying that is: If the tumbler were failing, wouldn't the lock *and* the alarm both malfunction? Thus I'm wondering how the alarm integrates with the door handle lock...
Thanks you for your help and insight!
