Depending on what state the alarm/immobiliser was set at, eg alarm on or off when you changed the battery, you will need to reset the system.

I can't remember offhand how to reset the thing but I believe it's well covered in the owners manual.

I think it's a matter using the door key and turning so many times to the left and right depending on your alarm code.

Sorry I can't be more specific.

If the problem is in the handset, then there is a laid down procedure again in the handbook for reinitialising a handset.
