Re: How to unhook my Security system?
I don't think you can do it. I think what they want to replace is the Wireless Control Module (WCM), sometimes called the SKey REmote Entry Module (SKREEM). This is an integral component and with it not working or disconnected, you flat will not be able to start the vehicle. If there is a way to bypass it, you'll need to have a detailed circuit diagram and some real good electrical/electronic knowledge.
You may want to check the internet for this part and install it yourself. It will then need to be programmed (at the dealer or by someone with a good computerized diagnostic scanner with this capability) with the VIN, key programming, TPMS info., etc. Good luck with this one.
