potentially create a risk of battery
explosion. Dispose of used batteries
according to instructions and local
laws. Do not attempt to burn,
crush, or cut the used battery, and
avoid exposing the battery to
environments with extremely low
air pressures or high temperatures.
Caution
If the RKE transmitter is not
reassembled properly, liquids could
enter the housing and damage the
circuitry, resulting in an RKE
transmitter malfunction and/or
failure. To prevent damage, always
