Transmitter Battery Replacement
NOTE: Perchlorate Material – special handling may apply.
See “www.dtsc.ca.gov/hazardouswaste/perchlorate.”
The recommended replacement battery is CR2032.
1. If the RKE transmitter is equipped with a screw,
remove the screw. With the RKE transmitter buttons
facing down, use a flat blade to pry the two halves of the
RKE transmitter apart. Make sure not to damage the
elastomer seal during removal.
2. Remove and replace the battery. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean it with
rubbing alcohol.
3. To reassemble the RKE transmitter case, snap the two
halves together.
