I may not be right but try holding down your lock button until the doors lock?
No
what answer!
After some extensive research on ls1gto.com and a few other sources, you cannot reprogram a 2004-2006 GTO Key. You must purchase a new fob, you can get them from Gene @ GMPartsHouse.com for a cheaper price. There are people who claim fobs can be reprogrammed, but I have never seen it documented or proven or a process of how to. I also own the factory service manuals (size of two phone books) and it states the FOB must be replaced. Good luck! Once you get your new FOB, there is a procedure you can find on ls1gto.com if you search for it.
your key fob can only be programed by the local gm dealer.
With the dealers scan tool.
You'll probably need to have this done at a dealership.
the bastards at the dealership have to do it...had it done, not cheap.
Take it to your dealership they would be the one to help you with that.
See www.isuzufaq.com entry 41. "How do I reprogram my keyless entry fob?" The first procedure (turn key 3x, close & open door 2x, turn key 5x, close & open door) worked for my 2002 Rodeo.
You normally do not have to reprogram the key when you replace the battery. If you do you will have to contact your VW dealer.
