[block ] (Lock): Press the lock button to lock all of the doors. The interior lamps will turn off after all of the doors are closed.When you use the remote keyless entry transmitter to lock the doors or use the delayed locking feature the parking lamps will flash and the horn will chirp.
The programmable horn chirp can be disabled by pressing and holding either of the door lock switches in the unlock position for 10 seconds with the ignition ON and all of the doors closed. When you hear the horn chirp, programming is complete.

Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it.
Under normal use, the battery in your remote keyless entry transmitter should last about four 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 your vehicle before the transmitter works, it's probably time to change the battery.
Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter.
