The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks

These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
