Remote keyless entry fob — battery replacement

1. The keyless entry system consists of a remote-control transmitter that sends a coded infrared signal to a receiver which then operates the door lock system. On models so equipped, the transmitter may also engage the alarm system and provide a panic button which flashes the lights and blows the horn for emergencies.

2. Replace the key battery when the smart key or wireless remote does not work properly. As the batteries deteriorate with age, the distance at which the remote transmitter operates will diminish.
