Havn't had a problem since then...the spare key still has the chip, my regular one does not. Both work great. Is this normal?
    NO. The one without the chip should not start the car.

    Re: Starting Disabled

    I had an ignition key cut by a local locksmith and thought $15 was rather steep until I began reading threads like this. I'd check out the local locksmiths before going to a dealer.

Anyway .... both my keys wont work and im not sure if i get another key made if it will work either... should i try getting one made anyway??? Has anyone ever tried the disconnect the battery thing to see if it works ??? Is there no way to disable the security feature ????

    Re: Starting Disabled

    I have a 96 Sedan Deville with the same issue. I'm going to attempt to put a resistor in myself but need to know where to buy them, can anyone help? All I have is a Chilton Manual, will this be sufficient in helping me or should I reconsider and take it to a mechanic or dealer?

    Re: Starting Disabled

    I had to get a steering wheel puller from Autozone and I got the steering wheel oof but I was unable to get the plactic part off. The chilton's manual again failed to give specific instructions for dismantling the colum. I was unable to get to the wires so I could not find any problem. However I havn't had a problme in about 2 weeks, should I act as if it's fixed or take it to a dealer?

    Re: Starting Disabled

    Bypassing the Vats system is quite easy as there are only 16 resistor values used. I would recommend bypassing the system as it is outdated but I would also recommend installing some sort of anti theft device too. I have to go over my notes and see if I can find where on the net it is posted. I have a hard time telling customers to spend that kind of money to fix an outdated system. The newer Passlock systems such as the 1 and 2 are now experiencing problems. The resistor is now in the ignition cylinder and works off the hall effect method. The problem with the resistor based systems is they are very easy to defeat by a thief, giving you a false sense of security. The new Passkey 3 system is transponder based and you have to use that exact key. Very effective! If I find the answer for the bypass I will post it.

    Re: Starting Disabled

    Does anyone have a wiring diagram for the 89 Eldorado steering column so I can try the resistor bypass fix?

    Eric, I am having this problem and can't afford the shop. I got a guy that can help, but he needs to know exactly what wires to cut for the resistor. I have the 89 Eldorado. Is it at all possible that you could please send a picture/diagram of exactly what wires to do what to? I can get the resistor measurement, but beyond that I am not sure what to do. What does the connector for this circuit look like, for instance?

    Please help, I can't get to work!

    Re: Starting Disabled

    Well, are all of your guys fixes still working? Did anyone ever have an opinion whether a new key can fix it if both keys currently do not work?

    If I get a keyless entry system installed will that fix it? Not that I can afford it right now, but just asking.

    Exclamation Re: Starting Disabled

    I am having the same problem with my 94 Deville. I find the same answer about disabling the VATS with a resistor BUT I cannot determine which wires are correct. I have been on my head trying to pick the correct wires but I have not been able to be positive about the ones to cut.
    Does anyone have a diagram or picture or link.

    Please help a large number of us start our cars!!!!

    Thank you

    Re: Starting Disabled

    I just repaired my 97 Eldorado starting problem today. I choose to insert a resistor that matches the pellet value in my key. You can go to Radio Shack and purchase an inexpensive volt ohm meter and use it to measure your key pellet. Then purchase a resistor that matches the value. Use a 1/4 watt fixed resistor or if you cannot find the exact value then purchase a variable resistor trim pot and adjust it to match your key pellet value. I used a 10 turn trim pot adjusted to a 2.33 kilo ohm value. Someone at the store should be able to help you with this.

    You will need to remove the cover under the steering column. Mine has a decor cover with a metal cover under it. Once you have all of that out of the way, locate the large multi-pin connector next to the column. Locate the 2 wire orange wire harness which should be in positions 12 and 13; they are the last two on that row. Positions 10 and 11 were empty on my wiring. Cut the orange wire harness about 3 inches from the large connector. Strip about 1/2 inch of insulation from the ends and solder or crimp the reistor so that it bridges between positions 12 and 13 on the large connector. The resistor should now be the only connection between 12 and 13, do not re-connect the wiring that goes to the ignition key switch. The engine should now start when you turn the key. Insulate and tie wrap the resistor. I tie wraped the resistor to some of the other wires to keep it from flopping around.

    Your anit-theft system will no longer function but at least the engine will start. Good Luck!

    Re: Starting Disabled

    I had a no start situation on Friday. After many hours of diagnosing and chasing, I narrowed it down to the Pass-Key. I did not feel like replacing the ignition lock cylinder so I came into the house and got on this forum and did a search. I found this thread and was able to get the car running for $.21 and many hours of my labor.
    I want to thank those of you that posted this info on here. It is a quick easy fix/bypass once you rule out everything else.

    Re: Starting Disabled

    the resistance on my key was 6.82 k or so and the resistor I have is 6.7 k Will this make a big difference in wether the car starts or not? Also, Does accessing these wires require dissasembly of the column and wheel? or the panel just below the dash? THanks

    Thumbs up Re: Starting Disabled

    I figured out the problem and repaired it today. Thanks to Hobnail for the procedure in getting through. One way that helped me to find which wire it was. It should be the two wires that are coming from the steering column that are about as think as telephone wires. Mine were white very thin and had an orange covering around them. Took me about 1 and a half hours and was fairly easy. THanks all. Great info!
