keyless entry remote battery

[Tommy00GT1]

Hi friends.. Anyone replace their battery in the remote control? I was wondering if it is a nightmare or easy to do. My owner's manual is not too specific. I'm wondering if it throws off the code of the 2nd remote by replacing the battery in the first remote. In other words, don't they have to be synchronized exactly the same???:roll2:

Thanks....

EDIT >>> The instructions below were taken from another forum. Those instructions vary from the way I was going to do it. Has anyone done it this way before ?

Transmitter Programming

Important

Once the remote control door lock receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information. You must then program all of the transmitters.

Up to 4 transmitters may be programmed.

To program the transmitters, perform the following procedure while seated in the vehicle driver's seat:

1. Close all the vehicle doors.
2. Remove the ignition key from the ignition lock cylinder.
3. Press and hold unlock on the door lock switch.

Important
To successfully enter the keyless entry programming/diagnostic mode, steps 4 through 6 must be completed within 25 seconds of pressing the door unlock switch.

4. While holding the door lock switch in the unlock position, insert and remove the ignition key twice. Do not rotate the ignition lock cylinder.
5. Insert the ignition key a third time leaving the key in the ignition lock cylinder. The ignition must remain in the LOCK position for the rest of the procedure.
6. Release the door lock switch. The chime will sound three chimes to signal that transmitter programming/diagnostic mode is active.
7. Press and hold the lock and unlock buttons at the same time on the keyless entry transmitter for approximately 4 seconds. The chime will sound two times to signal that the transmitter has been programmed successfully.
8. Repeat step 7 for the rest of the transmitters (for a total of 4 transmitters).
9. To exit the transmitter programming/diagnostic mode perform either of the following:
Remove the ignition key from the ignition switch.

You shouldn't need to program the transmitter for just changing the battery. When you change it all you have to do is sync it. I remember it's just holding the lock and unlock until the doors lock and unlock and that's it.

Programming the system is for adding transmitters.

Awesome, thanks a bunch Jay. I was all confused about it, lol...
I think I was reading too much about it from two different websites, and had both of them all mixed up....
Many thanks buddy....

Anyone know how to program factory remotes for a 2005 GA? The above procedure doesn't work.

Thanks in advance.
