1. Remove the small phillips screw located on the back side lower left corner of the transmitter.
2. Carefully pry the remote engine start transmitter halves apart using a small flathead screwdriver.

   

   

3. Remove the circuit board from the bottom half of the case and remove the battery and replace with new one. Be sure to observe the (+) sign on the old battery before removing it to ensure that the new battery is inserted properly (battery “+” should be pointed away from the transmitter circuit board on battery).
4. Carefully snap the case halves back together, reinstall the phillips screw and test the remote engine start system.
