Do i have high security keys ?
A good way to check key security is go to a local locksmith listed here in the locksmith directory and ask if it is possible to duplicate a key.
Most keys will have the name and a coded / encrypted number stamped on the key.
The number may be alpha numeric consisting of letters and numbers mixed i.e.: bht889. This is normally the key user number that tells the issuing locksmith what lock it will work. Then there will be a key cutting code telling the locksmith - key cutter what depths to cut the key and what code to set the key cutting machine on.
The simple fact is !
Registered - Restricted - security keys do work and provide good security. You just don’t know who has a copy key to your house. FACT !!
