Jeep 2011 Wrangler - Manual (Page 27)

If your RKE transmitter fails to operate from a normal
distance, check for these two conditions:
1. Weak battery in the RKE transmitter. The expected life
of a battery is five years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, military base, and some mobile
or CB radios.
Transmitter Battery Replacement
The recommended replacement battery is CR2032.
NOTE: Perchlorate Material – special handling may
apply. See www.dtsc.ca.gov/hazardouswaste/perchlorate
1. With the RKE transmitter buttons facing down, use a
flat blade screwdriver to pry the two halves of the RKE
transmitter apart. Use extreme care not to damage the
seal or internal components.
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.
