Dan, you can use the PKU-GM bypass module from Trilogix. We use this on the 2000 + Grand Prix's and no problems yet witht his module. They're a little pricey $ 70 MSRP but they do the trick and you won't loose a factory key to the remote start. PM for more details.Jeff

dtabet2: You can always just buy one of the modules that requires a spare key, and then buy an uncut key and program it yourself using the remote starter. howardkeys.com, hlflake.com, and eBay are places to find PK3 keys----any PK3 key will work. ziggyb222: I'm not familiar with that particular module Jeff mentions. At any rate, the "service theft system" message will appear if the car sees two transponder keys at once. Using the car's light green keysense wire, configure a relay so that the bypass module cannot work when there is a key in the ignition: 86: constant 85: keysense 87: not used 87a and 30: cut the ground-when-running wire that goes to the bypass module; connect the two halves of the wire to 87a and 30; doesn't matter which wire goes where. To reset the message, turn the key from Off to Run 7 times.

Hey Chris,  Thanks for the info.. I will wire that relay and reset the light.. Thanks for your help...
