Keyless Entry Transmitter Battery: Service and Repair
Transmitter Battery Replacement:
Under normal use, the battery in the transmitter should last about two years.
You can tell the battery is weak if the transmitter won't work at the normal range in any location. If you have to get close to the vehicle before the transmitter works, it's probably time to change the battery.
