Default Coding Key

The other day when I did my timing belt I disconnected the battery now my remotes don't work. I was told there is a certain sequence when you put the key in the door and hit the unlock or lock buttons. nyone know?

This is what I did I hope this works.

-Get in the car, make sure all doors are closed
-Put the key in the ignition
-Start the car while holding the lock button on the remote
-Turn the car off
-And the remote should work.

Note: If the car has immobilizer, you have to take it to the dealer.

Otherwise, this should be the correct procedure:

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.

Sorry for the cut and paist from another site......
Don't like the site they try to infect your computer so I didn't paist just the link.

I did this but put my hand in the open drivers window with the key I was
programing in the door. And locked and unlocked the door with the botton in the door. Not the botton on the FOB.

Hope this helps?
