    Passkey problems again - 1999 Eldorado ETC

    Hello all,

    I have spent the last few hours browsing message concerning the 'starting disabled - remove key' error for cadillacs. There is a lot of information here, and I wonder if anyone has any advice on my own related problem. One thing that seems to be different is that the security light does not come on:

    1) A week ago I tried to start the car and got the 'starting disabled - remove key' message. The problem is not intermittent - since the first error, it has always repeated.
    2) I do not get a message asking me to wait 3 minutes
    3) The security light is not on
    4) I do have the error code B2710 current and B2750 history
    5) If I leave the key in the on position for a few minutes, an additional message appears saying that the fault is from the antitheft system and that the car may not restart.

    I am not sure what the cause of the error might be and wonder why the security light is not on (it does work and lights for a couple of seconds when the key is turned to on)?

    Also, I was thinking of trying to get a new key made and measured the resistance across the pellet on my key - it reads 600 ohms which does not seem to match any of the 15 key types I have read about. There is a key listed at around 530 ohms and another around 650 ohms - strange?

    Unfortunately, I am far from the U.S. (In UAE) and it is very difficult to get service for the car here. My only option, if I cannot fix it myself, is to have it towed around 120km to a service center in Sharjah.

    Any advice would be appreciated,

    Thanks in advance,

    John.

    As a quick follow-up to my post above, it just struck me that perhaps I read the resistance incorrectly on the key - there is apparently a 6,000 ohm key and probably I did not read the scale correctly. I will check when I get home!

    You won't be the first having a non standard VAT, my original key was dead center between two VAT values.
    Read more here. Do the thing I mentioned on post #5 and tell me what value you get.
    You don't need to tow the car that far for such a simple issue, is just a matter of removing the daspad cover to get access to the IPC connectors and remove the 2 wires and place a resistor matching your key.

    Some people cut the wires under the steering column (between E2 and E13 pins and the Ignition lock cylinder ) but my advice is: DON'T ever cut a wire in your car, just get a connector with a pigtale harness and use the wires to insert into the connector in your car once you solder the resistor (see with red above). If I would be in your area I would fix the car in 10 minutes. See here for example, it is such a simmple matter.

    Hi - Thanks for the quick response. I will give this a go, although I am not much experienced in electronic or cars! I was reading other posts which mentioned removing a 'kick-panel', I think below the steering column, to access the wires. In your post, you are suggesting it is better to do this by removing the dashpad cover - is this the dashboard cover above the instrument cluster?

    Also, I rechecked the key - it does in fact read 6010 Ohms, rather than the 601 I thought at first. I will look for a 6kOhm resistor on ebay - does the wattage rating matter? I think I saw something about using a 0.5W, but I have not yet found any with both of these specs.

    Thanks and best regards,

    John.

    6010 is VAT 12 (6.040 KOhm - normal but accepted values are between 5.798 KOhm and 6.302 KOhm.

    Yes the dash pad cover is the top of the dash pad; look for removal instructions, must be posted hundreds of times. Everybody goes for the kick panel because ... I don't even know why. The best way to do it is as I showed in post #3.
    Wattage...it really doesn’t matter, a 0.25W resistor is good enough, the current is almost neglectable.
    Remember this is a PATCH, is not the real deal fix, the proper fix is to replace the ignition cylinder, you can probably find one on eBay (rockauto.com or rippy – unfortunately since you are not in US…rippy may not be able to help you).
    But when replacing the ignition cylinder you either transfer the tumblers from your existing one (so you can use the same key) or you need to purchase new keys and have them cut to match the new pattern. Either way, remember your car uses VAT 12 keys.

    on my 1989 Cadillac Seville, the wires that I had to put the resistor on was yellow, but if your car has airbags, you have to look out for those wires and make sure you don't cut them.

    There is no airbag wire going to any of the 3 IPC connectors.
    NEVER EVER go by wire colors, you always use connector pin numbers, the wire colors are not reliable (can change from year to year) plus may be duplicated.
    WAIT A MINUTE!!!!
    Who said something about cutting wires?
    NEVER EVER, EVER, EVER cut wires (notice what I mentioned in my diagram).

    Keep in mind this is just a TEMPORARY patch until you replace the ignition cylinder.

    Re: Passkey problems again - 1999 Eldorado ETC

    Dear All,

    Many thanks for the help. I have the car up and running again after installing a 6k ohm resistor. After the many problems I've had (A/C, suspension, cooling system, electrical ...) and the difficulties here getting parts/service, I think it is time to give up the car while it is running!

    All the best,

    John.
