Offering the maximum level of security for entrance doors.

The APECS AP is our BSI 3 Star Kitemark, Sold Secure Diamond Standard Euro Cylinder which offers maximum protection. It safeguards from all forced methods of attack ranging from snapping, drilling, plug-extraction, picking and bumping.

The APECS AP cylinder is specifically designed to protect from unauthorised access by burglars. The AP cylinder is engineered with a unique sacrificial point, which when tampered with externally sets an interlocking cam mechanism into action, preventing any further damage to the internal parts of the cylinder, whilst still keeping the lock operable from the inside.

In the event of snapping, the home owner can still operate the door and exit the property due to the lock's unique mechanism which is engaged when the cylinders external section is snapped off. This mechanism slides the clutch into place, preventing further external damage and manipulation of the cam, whilst keeping the lock operable from the inside. 

The APECS AP euro cylinder is available with 5 keys and this can be selected when ordering. 

What is the button on the AP Cylinder used for?

The button the thumbturn AP cylinders allows the customer to exit the property if the lock has been damaged on the external side. The technology on our AP means that if the cylinder is snapped on the external side, the internal mechanism cannot be tampered with, meaning that the homeowner can still exit the property. This is usually done by using the key, but with our Thumbturn cylinders, this is done using the button.

What is the APECS up to £2500 Break In Guarantee?

To give you total peace of mind, in the unlikely event of a break-in succeeding through a snapping attack on our cylinder, we will pay up to £2500 towards the loss of any items which are not covered by any of your household insurance policies.
