With three mounting sizes available, the KeyDefender can be installed in multiple locations within the vehicle 

using the RAM® mount system. RAM® mounts have an adjustable arm with 2 adjustable bases on the top  

and bottom. The handle can be rotated to loosen the bases and then tightened to lock the bases into the 

preferred position. 

Included are security fasteners to mount the KeyDefender to the RAM® mount. Fasteners are not included 

to mount the RAM® bracket to the vehicle interior. Customers are responsible for determining an adequate 

mounting location and securing the RAM® Mount to the interior of the car. The maximum fastener length into 

the back of the KeyDefender is 5/8”.
