Key Fob Losing Code?

[DG]

The batteries on my lock key fob died, so I replaced them.

I can see the LED on the fob light up when I press buttons, but nothing happens on the car.

Can these things lose their code? Is there a procedure to re-sync the fob and the car?

Copied from the other site Wiki:

You need to get to the keyless receiver, which is located behind the rear, left-side (driver's-side) panel, that is, the large panel which surrounds the left rear speaker. The whole procedure will take most people around one and a half hours, including re-assembly. (For those who don't want to do it themselves, any car audio installation shop can easily do it.)
Here's the procedure:
1. Remove the hatch cover.
2. Remove the rear seat as follows:
Pull on the two handles at the forward edge of the seat bottom. This will unlatch it so you can lift out the whole seat bottom. Remove the left side rear seat-back, by undoing the two 12-mm bolts, which are at its base.
3. Remove the left rear panel as follows:
Unscrew the rearmost screw on the scuff plate (the plastic strip that sits over the rocker panel.) Unscrew the single screw on the cover over the rear seatbelt retractor, and lift off this cover. Remove all the screws holding on the large panel. The only tricky part is getting to the two screws at the rear seatbelt retractor - there is not much space, so you will need a short screwdriver. I used a long Phillips screwdriver bit with a socket and it was easy. You don't need to take off any seatbelts - just let the panel hang with the seatbelt still through it.

4. The receiver is the large box forward of the speaker. There is a 3-position switch on it marked SET 1 - FIX - SET 2. You will find it easier to access this switch if you remove the receiver from the car body. Move the switch to either SET position (the two SET positions are in case you have two transmitters with different codes), so that the receiver will learn the new code. Press either button on the new transmitter. Move the switch back to FIX, to retain the code. Test the new remote operation - it should work.
5. Reassemble everything, making sure that the antenna connector is snug in the receiver. You're done.

Ack, thanks.
