CBN BUILDING MAINTENANCE
KEY SECURITY

We copy your door keys onto hard-to-duplicate "neutered" key blanks, featuring:

• No manufacturer or brand of lock on blank.
• No number/letter code to identify type of keyway.
• Incised "Do Not Duplicate."
• Rectangular head, generally used only for security keys.
• Our crews are not allowed to place your firm name, address, etc. on your keys: lost keys are less likely to point to your building.
