Programming
To program your replacement key, you'll need to do the following:
Common Problems
If a new or original key stops working, the most likely culprit is a faulty battery. The internal chip in your key fob could also be damaged or require further programming, which would need to be done through a local dealer using specialized equipment. As well, be sure the retaining clip is holding the battery in properly. If it's damaged, you transponder won't work and you will not have access to keyless entry until the problem is fixed. An issue with your wireless control module could also prove problematic. Try resetting it (e.g., disconnect and remove car battery, pull out the IOD fuse using the fuse puller, wait 30 seconds and then put everything back into place). If there is a short, however, you'll need to seek outside help unless you are skilled in replacing modules.
