Be careful! Your 'tour could have the PATS system. How big is your key? If it is rether large, it probably have a chip in it that the car must "hear" from to allow the car to start. DEI makes a device (555F or 555U) to interface with the PATS system and allows the car to start. The only problem is that these can be a little tricky to get set up right. Do you have experience installing alarms? This is not a good rookie mod. Hope this helps!
