Who has keys to YOUR home or office?

Terminated Employees? ~ Your Ex? ~ An Old Roommate? ~ Fill in the blank: _________?



Standard keys marked with “Do Not Duplicate”, “Do Not Copy”, “Duplication Prohibited”, etc. can usually be duplicated at any locksmith, hardware store… even the automated key kiosk. It is not against the law to duplicate these keys since the key blanks to fit these locks are commonly available.
Most KEY CONTROL systems utilize Restricted, Patent-Protected or High Security Lock & Key Systems and/or cylinders. Because they are patented, the duplication of keys can only be done by factory-authorized professional locksmiths. 
KEY CONTROL is a ladder, the higher you go, the more secure your facility.
