Institutions with redundant systems like yours are the best at stopping criminals. The traditional deadbolt locks installed in one's house are great protection for a home. Of course, this is only true if the bolt into the door frame is installed at least 1 1/2" to 2" into a 2/4 board. Otherwise, home door locks can be easily compromised by exterior items like rocks or decorations. Very few homes have backup systems, so the locks are the only items they have to protect the home. In your case, we have to weigh the benefits of your systems against a deadbolt lock. If the deadbolt was your only system for protection, I would be for it. As you have a camera system, motion detectors, and keyless entry system you have redundant security in place. This system is superior to a key lock system alone when we evaluate the benefits: an employee quits but won't return the keys; the institution terminates an employee and can immediately revoke their access without worrying if duplicate keys exist; an employee is kidnapped at home and forced to the institution after hours only they can't enter because they only have access at certain times of day. As long as your system passes the local fire code inspections, I would advise keeping what you have. When our firm performs physical risk assessments, one of our number one recommendation is to abandon the key system and convert to keyless entry as you have.
Exterior Door Locks

Question:
Would you mind giving your opinion on proximity card/fob access control on exterior doors for a financial institution? We have recently completed a new build and installed a keyless entry system on crash bar type doors. There is a key bypass option and, in the event of a power failure, the locks default to locked, requiring the key. Our president is of the opinion that these locks are not secure enough and is leaning toward adding traditional deadbolt locks. Of course, we have
door contact alarms and cameras as added security measures. The security department and our security vendor are of the opinion that these locks are as secure as other types. The ability to immediately disable or add users, eliminating the cost of locksmiths, the creation of entrance logs, are among other benefits.
