ABSTRACT:
A remotely controlled door lock for a dog cage is provided. The door lock includes a pair of solenoids connected to a latch bolt, and a main controller which receives a radio frequency control signal from a remote radio transmitter. The main controller decodes the signal and sends it to one of the solenoids to retract the latch bolt from engagement with the cage door, or extend it into engagement therewith.
