Lock stickers should also be a part of your lock security program. Any time your near a lock for any reason you should check to see it has a sticker. I normally don't call the tenant if a new lock has been added, unless their access code was not used for two weeks. Cylinder locks do not have a sticker security program that Im aware of. Security hasps can be used with cylinder locks.

The cylinder lock. Why is it safer? Because everyone in any facility that uses them must have one. There is no cheap locks being used at the facility. There is two sometimes three "overlocks" which can be used by the lock and Hasp.

A lot of good information here -- thanks to all of you for your input.
