My (6 month old)battey went dead last night, and now my keyless entry doesn't work. I was looking at the remote but it didn't look like I could open it to replace a battery.

I'm tired and confused right now as I've been driving 3 hours a day just for school, and am in the process of moving.

 

I have on '05, but I figure changing the battery in the remote is the same, so here it is out of the manual:

Replacing the battery
The remote entry transmitter uses one coin type three-volt lithium battery CR2032 or equivalent. To replace the battery:
1. Twist a thin coin between the two halves of the remote entry transmitter near the keyring. DO NOT TAKE THE RUBBER COVER AND CIRCUITBOARD OFF THE FRONT HOUSING OF THE REMOTE ENTRY TRANSMITTER.
2. Do not wipe off any grease on the battery terminals on the back surface of the circuitboard.
3. Remove the old battery. Note: Please refer to local regulations when disposing of transmitter batteries.
4. Insert the new battery. Refer to the diagram inside the remote entry transmitter for the correct orientation of the battery. Press the battery down to ensure that the battery is fully seated in the battery housing cavity.
5. Snap the two halves back together. Note: Replacement of the battery will not cause the remote transmitter to become deprogrammed from your vehicle. The remote transmitter should operate normally after battery replacement.


Hope this helps.

 

thank you, I was going nuts not having remote entry

 

changed out the battery in the remote and it's still not working, any other ideas?

 

You can try this, Note this is for an '05 but hopefully it will work for you:

Deactivating/activating power door lock/unlock disable feature
All vehicle doors must be closed before beginning the procedure. You must complete Steps1–5 within 30 seconds ,or the procedure will have to be repeated. If the procedure needs to be repeated, you must wait a minimum of 30 seconds to begin again.
1. Turn the ignition to the 3 (ON) position, then press the button three times.
2. Turn the ignition to the 1 (OFF/LOCK) position, then press the button three times.
3. Turn the ignition to the 3 (ON)position; the horn will chirp to indicate the driver configuration mode has been activated.
4. Within five seconds, press the control two times. Note: One horn chirp should be heard, indicating the system has been disabled.
5. Turn the ignition to the 1 (OFF/LOCK) position to exit programming. Note: After exiting the driver configuration mode, the horn will chirp once to indicate a feature has been activated/deactivated.

If this doesn't work, the manual states:

If there are problems with the remote entry system, make sure to take ALL remote entry transmitters with you to your authorized dealer in order to aid in troubleshooting the problem.

I hope this does it for you and you don't have to make a trip to the dealership. Good luck.
