If an intruder attempts to snap an ABS Master 3* Diamond grade cylinder an initial sacrificial section will deploy - This allows the lock to still operate from outside using the key on the remaining section but makes it difficult for the intruder to remove the second part of the cylinder.

Any attempt to break the lock past the two snap off points will result in the patented Active Snap Protection activating to totally lock off the cam. The ABS Master 3* Diamond grade cylinders keeps the intruder out and your home and family safe.

Why do ABS 3* Diamond grade cylinders have dedicated snap security on the external side only.

ABS Master has all snap security features on the outside only - to ensure the inside section does not break away when attacked.

If ABS Master has been attacked and snapped from the outside the homeowner can still open and close the door safely and securely from the inside.

Your ABS Master lock includes a unique key code system which you can link to you. You can do this onlineor over the phone 24/7 every day of the year.
