    2006 STS4 Key Fob Replacment/Programming

    Ok gentlemen,

    2006 STS4 - I lost key fob #1 and am looking on eBay for a replacement. I am currently using fob #2. I am currently seeing new fob number 1's going for $50-100 or so. The question I have is this. If I buy fob number one, I know that I will have to relearn in to the STS. BUT HOW? I really don't want to pay dealer labor on a silly deal like this. Can anyone help??

    This will be my first post. I might be able to post some pics of the baby on here soon as well.

    Thanks again in advance.

    At the top of the forum: Sticky: Problems, help and questions: Body, electrical and interior: Programming fob

    It is also in the owner's manual if you have one. Listed under, Matching Transmitter(s) to your Vehicle

    The procedures listed here are a bit more clear than the ones in the manual because people who have actually done it have tried to clarify them. For example, since you are not simply adding a fob, but replacing a lost fob, you will want to begin with all fobs at least 30 feet away from the car until the procedure calls for fob 1.

    If any fobs that have ever been matched to the car are within sensing distance during the start of the procedure, the new fob will be matched as #3 or #4 and then cannot be used to automatically recall a Driver Preset or Remote-start the car.

    On very rare occasions, members have reported bad fobs that do not respond properly to the procedure. Although I really like the new-style fob used beginning with some 2007 models, it does require some metal-working skills to fit a copied physical key into the fob. I like carrying one less visible key but the range of the new-style fob remote start may not be as good as the 300 feet of the old-style one. It may also use batteries faster and/or need cleaning/adjustment more often, too.

    Firstly, thank you.

    Ill try to stay away from purchasing any later model (2007) replacements. Do you advise on purchasing a brand new replacement or would it be okay to purchase a used fob?

    I seem to have misplaced my manual and cannot find it. The fob # 2 seat memory seems to want to always default to fob number one seat memory for the recall. When I turn the car off and open the door, the seat then changes to something that I've never seen before. It actually pushes me closer to the steering wheel and the telescopic steering wheel also comes out. I've tried to engage the "recall steering wheel" feature when exiting while using fob number two, however I've been unsuccessful.

    Thanks again for everyone's reply.

    Hi, the posts from our members are very detailed and accurate. However, if you misplaced your manual and don't want to spend the money to buy one you can view the entire manual online for free. The website is www.justgivemethedamnmanual.com. Very easy to use and free! Good luck!
