Default no..

the key does not get programed. The car gets programed to the key. he key has a resistor in it that mates with the imobilizer in the car. The fob battery is only for the transmitter for the lock button.

Default There's a proceedure, I think it is described in the manual, where you need to use BOTH

key fobs.

Here is what is listed on Stony's links (courtesy of meq123):

1.Take one key/remote (key B) and put it in the ignition and turn the ignition ON (to the "accessory-on" position - don't start the car).
2.Close and lock the driver's door with the other key/remote (key A) while the ignition remains on.
3.Take the key A remote and press the "UNLOCK" button ONCE only - alarm will 'beep'/lights flash, but door will remain locked.
4.Wait for a slow count of 10.
5.With key A, unlock and lock the door again (using the key not the remote).
6.Test the remote by pressing the "UNLOCK" button again - door should unlock.
7.Open the door and turn ignition off and back on again using the key A this time.
8.Continue the procedure for the second remote - close & lock the door with the key B (leaving the ignition on).
9.Take key B remote and press the "UNLOCK" button TWICE - alarm will 'beep'/flash each time button is pressed but door will remain locked.
10.Wait a count of 10 again.
11.With key B, unlock and lock the door again (using the key not the remote).
12.Test the remote by pressing the "UNLOCK" button again - door should unlock.
13.Remove both keys, close the door and perform a final retest by locking and unlocking the car with both remotes.

If this doesn't work, repeat WITHOUT steps 5 & 11.
If that doesn't work, you're on your own :-[
