It’s both liability and labor thing. When a tenant moves out, large apartment buildings change the lock. With an electronic lock any member of staff can ‘rekey’ the lock in a few seconds. For liability, the large companies use big key control systems to try and track which staff is checking out keys to what, but it’s still possible for staff to make unauthorized copies. With an electronic lock they get a nice report that shows all the times the lock was used and when the door was opened. And finally, many property managers are control-freaks and they love that tenants need to ask to make ‘copies’ of the electronic keys. Previously the only real option for key control was something like Medeco and most don’t want to pay for that.
