Abstract: An alarmed cable lock that sounds an alarm upon an attempt to open the lock or remove the secured item while the alarm is armed. The invention includes a lock, a cable, a power source and an alarm. The lock includes a C-channel closed at one end, a switch, and a blocking pin. The cable is attached at one end to the lock. The free end of the cable terminates in a head that is formed to slide in the C-channel. The switch is exposed in the C-channel. When the lock is armed, the blocking pin extends into the C-channel to prevent the free end of the cable from sliding out of the open C-channel end. If an attempt is made to remove the end of the cable by sliding it out the C-channel, the head passes by the switch and sets off the alarm. The alarm/lock features are operated by remote control.

Abstract: An electronic system of locking and alarming one or more doors such that if an attempt is made to open the door, the alarm sounds. The device is preferably installed on vehicles having multiple built-in equipment compartments. The device is powered by the vehicle battery and includes a novel lock mechanism which requires very little power. The lock mechanism comprises a lock housing, a pin, a pivoting latch gate, a switch and a solenoid. The device is electrically connected to a vehicle's conventional remote-controlled security system and sounds an alarm if an attempt is made to open a compartment door.
