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.
