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.
