Do you have a PK3 stamped on the metal shaft of the key

hope this helps >you will need a pass key 3, or simply another key in a universal bypass box. if tried to remote start, and the car tried and quit, i believe that you are to use the key, do not start the car, wait about 30min. this should show that the pats system in the car recognizes that it is not being stolen. I dont know what security system you are using, post and I can probally dig up more info. on another note, this site offers diagrams and as I see some great help. i am new to this forum but have been in the industry for 13 years. dei makes a simple bypass module, however dei has changed their inventory and i have no suggestions for that module. take care, this seems to a nice forum, jeckyl ------------- I am a tech that was laid off due to a car accident, I was a passenger. I have been in the audio industry for 12 yrs. I have lost some memory and would just loike some help. Nate

The Passkey 3 system on that car sends a "fuel enable" signal from the receiver at the key cylinder to the Powertrain Control Module, whenever a valid key is read by that receiver.
Your problem unfortunately cannot be resolved by just disconnecting a part or cutting a wire. However $700 sounds extremely steep. Best to call several other places first.

Try the passlock 2 method. Wind down the window, put the key in the ignition and turn it to the ignition spot, get out of the vehicle. In about 10-15 minutes, come back, turn the ignition off, then try to start the car. As chris said, the Passkey 3 also controls the fuel pump to prevent theft. If that doesn't work, disconnect the positive lead from the battery, get in your car, press the brake pedal a few times to bleed out any residual power. Leave it disconnected for about 1/2 hour, reconnect, then try starting. If neither of those work, sounds like a bad ignition switch or Passkey 3 went wonky.

or BYPASSING SECURITY ENGINE NO-START & KEY RELEARN PROCEDURE SYMPTOM: Vehicle starts but only runs for 3-5 secs.Security light continues to flash when Key is inserted and advanced to the RUN position. QUICK FIX:
Turn the key to the RUN position – Observe: Security light will flash.
Leave Key in the RUN position
Disconnect (-) battery cable for approx 3 mins.
Reconnect (-) cable and TURN Key from RUN to START.
Security light may continue to flash but will disappear after a short time.
Security light may re-flash after a restart, and a PASSKEY III Relearn Procedure may be required.
Thanks to tholland. DIY PASSKEY III RELEARN PROCEDURE NOTE: Battery will discharge during this procedure (approx 30mins total). Connect Battery Charger if possible 1. TURN Key to the RUN position until security light disappears..(Approx 10mins)
2. RETURN Key to the OFF position for ~5secs.
3. REPEAT Step 1.
4. REPEAT Step 2.
5. REPEAT step 1 for a third time.
6. ADVANCE KEY directly from the RUN position to START…. If still no go, turn the key back to off for 5secs and then start.

The repair price of $700.00 may be accurate. There are a couple of possiblities to try first. If you have another key for the car, does it work? If you have more than one and neither key works, it could be a defective theft module. When you factor in the cost of the part (over $500) and a couple of hours of labor for the dealer to change and program the new unit, it will likely come to this amount. Make sure that you get the dealer to stand behind their diagnosis. If the repair doesn't fix the problem, then you shouldn't have to pay for it. Unfortunately, there isn't any method to bypass the system if the main module is bad.
