Locks and keys are the basic safeguards of any business. They are the first layer of security. The type of lock and key system you have will be governed by how much security you need and your budget. Even the best system will fail if it’s not managed correctly. Keys can be lost or stolen, so a system in which keys are marked “DO NOT DUPLICATE,” is a good investment. A numbered system, which can be audited and updated, will ensure good key accountability. When employees leave the company or a key is lost you should consider changing locks and keys. Remember, locks and keys are useless if not properly controlled.
