Default Gm has my key code but not the Vats/PASS code

Any ideas. I've lost my keys, and for some reason GM did not keep the record of the PASS code that responds to my car, what do I do?

I don't think it matters what the code is, doesn't the CAR store it? When I got my PKE I just followed the directions to program it. It took about 5 mins.

If my recollection serves me correctly (which it often does not) you can plug a scanner into the ALDL and scan it for the correct code. Unfortunately, it's a matter of trying all 13 key blanks while scanning. Your dealer should know what to do. (The service guy. Not the parts counter guy.)

Someone will soon correct me if I'm wrong.

The part on the key the has a capacitor with different resistance to start the car.

VATS bypass harness. I think I got one from MAD. But you may need the VATS value first. Kinda Catch-22...

Actually the part on the key is a resistor, not a capacitor

:iagree:

You can get at the vats resistor input under the dash -you can then use a regular resistor of the correct value from radio shack (they are cheap, if you can find out all 13 possibilities). Then try thrm one by one, but you'll have to wait until VATS is done locking you out until you try the next one.

Off the cuff . . .

Take the steering wheel and lock cylinder off, get 2 aligator clip jumper leads and 13 resistors from Radio Shack (about $1 a pack), and try each one while trying to crank the starter using a scredriver where the lock cylinder used to be. Be sure to wait 10 minutes between each crank attempt. (There's a chart listing the resiting values for each of the VATS resistor codes here on the forum someplace.)

Alternatively, get a key made (with VATS code 1), gets a VATS bypass kit (with VATS code 2), and 11 resistors for VATS codes 3 through 13. If 1 and 2 doesn't work, begin swapping out the resistor in the VATS bypass kit. This will save you from removing the steering wheel, but you'll have to wait for the VATS bypass kit to be Fed Exed to you by MAD or Eckler's.

Just a thought.

I don't think so.

After putting the paper clip in those two, turn the key on. This will put the CCM in diagnostic mode.

You need a key to do it.

Also, I don't think you can jumper the pins on OBDII but it should be ok for his car being OBDI.

This makes me think I really should get an extra key for my car while I have one though. :yesnod:
