Transmitter Battery Service
The replacement battery number is 2016. This is a generic
battery, readily available at local retail stores.
1. Pry the transmitter halves apart with a coin or similar
object.
2. Remove and replace the batteries.
3. Reassemble the transmitter case and test operation.
NOTE: If the transmitter is operated more than 255
times out of range of the vehicle (23 feet or 7 meters) or
when the vehicle battery is dead, it may become “out of
synch”. The result is that the transmitter will not func-
tion.
To correct this condition, remove the key from the
ignition and close the hood and all doors. Press both
buttons on the transmitter for about 10 seconds. The horn
will chirp once to acknowledge the signal. Normal trans-
mitter operation should resume.
