All CES keys are made of nickel silver. Our keys are also thicker than most at 3.5mm, and with longer shanks (at least 14mm), to provide maximum strength, durability and of course, security.
CES keys are patent protected for protection against duplication. We provide security reference cards for each and every cylinder we manufacture to allow for verification before we provide duplicate keys.
We understand that key requests need to be dealt with swiftly, but we maintain your security by our strict processes which allow us to confirm your authority to receive new keys. We will give your requests our utmost priority but please ensure you have the necessary evidence of authority available, before getting in contact.
