Key control is important. If someone has access to a key, the lock is useless. Do not leave keys lying around. Keep a list of who has been issued keys in the past. Have keys stamped with "do not duplicate." Change locks or cylinders as frequently as needed. Deadbolts provide increased security. Use deadbolts with at least a 1-inch throw bolt, and a steel guard ring around the key section to prevent prying. Double cylinder deadbolts require key access on both sides and are useful if near a window that can be broken. But, these locks can also prevent exits in an emergency, so check local regulations. Padlocks: If a padlock is used to secure a door, then it should be case-hardened steel, with bolt-mounted hasps to prevent removal. Also, always keep it locked to prevent an offender from switching the lock when open. ![]() |
