Key Systems Tamper-Proof Key Rings® are engineered for high security and long-term reliability, making them ideal for key control systems, asset protection, and secure key management programs. The patented tamper-proof design prevents unauthorized removal, swapping, or substitution of keys and attached assets, providing clear visual evidence if tampering is attempted.
Key Features & Benefits
-
Tamper-Proof Security
Once properly crimped closed, the ring cannot be opened or reused without visible damage, ensuring accountability and asset integrity. -
Unique Identification
Each ring is permanently engraved with a unique serial number, allowing quick verification of correct key sets and immediate detection of substitution. -
Multiple Sizes & Styles
Available in solid stainless-steel and flexible braided stainless-steel versions, with multiple diameter options to accommodate different key quantities and applications. -
Smooth, Low-Profile Seal
The sealed design allows full 360-degree rotation of keys without sharp edges or obstructions after crimping. -
Optional Color-Coded Control Tags
Color identification tags can be added for fast visual organization by department, building, or authorization level.
Smooth Seal
Our crimping tool closes both solid and flexible rings with a smooth seal. This allows for a 360-degree use of each ring without the hindrance of a raised seal.
Unique ID
No two key rings are alike and are uniquely identified by a permanent serial number. Each ring is engraved before distribution to allow for detection in the event it is tampered with or replaced.
Flexible Rings
Each size of Tamper-Proof Key Ring® is available in both solid and flexible braided stainless steel. Both solid and flex rings are sealed with our same Crimping Tool.
Color Code Control
The only plastic we use with our Tamper-Proof Key Rings® is the color-coded tags. Five colors are available to help group key rings for quick identification.
