flatback2 Posted March 16, 2005 Report Share Posted March 16, 2005 Got up this morning started to go to work, put the key in and turned, she would not crank, had power, radio, etc., looked down to see message "STARTING DISABLED". Acted like a shifter switch so I moved the shifter up and down, nothing. Tried a few thing with no success then finally locked myself in the car with the fob and she started. Went out after work fine, stopped at a store fine and then I stopped again and same deal, no crank and "STARTING DISABLED" message. So now I know what to do right , wrong. Locking myself in with the fob did not work this time, this time she started when I moved the shifter up and down. Not much consistancy there. What causes this ? Is there a time reset sequence ? Both times it took me a minute to fool around with it. Thank you for putting up with me. Link to comment Share on other sites More sharing options...
adallak Posted March 16, 2005 Report Share Posted March 16, 2005 Bad contacts on your key or ignition lock. Another possibility - wires within ignition lock are about to move south. You will not be able to start the car some time soon. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...

Scotty Posted March 16, 2005 Report Share Posted March 16, 2005 wow Caddy had the forsight to create a dashboard message for a ignition lock or wiring problem. they are on top of everything Its not an ignition lock or wiring problem, its related to the security system, if you look at your key it has a resistor embetted in it, if it does not make proper contact you will set off that message, Mike Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home.

davedog Posted March 16, 2005 Report Share Posted March 16, 2005 if you have a spare key, try using that. If the spare key works, then you know you need a new key! -dave Crystal Red Tintcoat Exterior | Shale/Brownstone Interior | 32k Link to comment Share on other sites More sharing options...
flatback2 Posted March 16, 2005 Author Report Share Posted March 16, 2005 The old electronic seed in the key trick, yes I remember now. I do not have a spare so I guess I need one, what are they worth? $100. How does one make bad contact with the key ? Is it like wireless or does it actually make contact with something ? Is my key chip just weak or do they just go ? How could I damage the chip ? Could I have set it on a magnet somewhere ? I do not remember putting it in the microwave but perhaps on top ??? cars Link to comment Share on other sites More sharing options...
Scotty Posted March 16, 2005 Report Share Posted March 16, 2005 You didnt damage it, its probably not making good connection. Try cleaning your key and lightly spraying it with WD40 and putting it in and out a few times to clean the contacts in the switch, do not spray anything into the lock, try to transfer the WD40 from the key to the lock.

adallak Posted March 16, 2005 Report Share Posted March 16, 2005 Do you have a lot of stuff on that keyring? Excessive weight may pull the key down and affect the contact with the lock. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
davedog Posted March 16, 2005 Report Share Posted March 16, 2005 i had a copy of mine made at the dealer for $25. my caddy only had one set of keys when I bought it. Microwave it if you wish, but i'd get a spare made first -dave Crystal Red Tintcoat Exterior | Shale/Brownstone Interior | 32k Link to comment Share on other sites More sharing options...
flatback2 Posted March 16, 2005 Author Report Share Posted March 16, 2005 looked at the key under a magnifying glass, didn't look excessivly dirty, wiped it down good. Took a run and stopped and started it about 20 times taking the key out and reinserting it. It did not fail to start, thanks for the ideas Link to comment Share on other sites More sharing options...

flatback2 Posted March 30, 2005 Author Report Share Posted March 30, 2005 The Eldo has been running and starting since I cleaned the key but as I was driving down the road last night the dashboard said "problem with theft system" then flashed "car may not start". Car started fine, tried it several times. You think these things are related ? Link to comment Share on other sites More sharing options...
druhl Posted March 31, 2005 Report Share Posted March 31, 2005 They are definitely related. It sounds like you need to clean the contacts in the ignition switch it the key is clean. try cleaning the key resister with a pencil eraser . As for the contacts in the switch , maybe some contact cleaner. Link to comment Share on other sites More sharing options...
navion Posted March 31, 2005 Report Share Posted March 31, 2005 Locally ACE Hardware is advertizing that they now have the GM keys with the anti theft resistor in them. I think they were around $20 to $25. If you get something on your key, gum, hair spray, ear wax, (sorry, I have seen someone use their key to clean their ears ), etc. you will transfer it into the ignition switch. I haven't ever had one of these switches apart, so I couldn't comment on how best to clean one. If I was going to try it, I think that I would use a sliver from a tounge depressor, and try to burnish the contact area in the switch. You would have to be VERY careful not to break anything off inside the switch! I would be very hesitant to use solvents in the switch. If you must use contact cleaner be sure that you get some that states that it is "Safe for Plastics". If you can get a product that states thet it is safe for radio tuners and plastics, that is better. If you are getting the warning, then I would fully expect that it will fail at sometime in the near future. Good Luck, Britt Britt Link to comment Share on other sites More sharing options...

BSchlossmann Posted March 31, 2005 Report Share Posted March 31, 2005 This problem happened twice to the previous owner of my 93 Eldo. Both times the ignition lock was replaced to correct the problem. I have put 50k miles on the car since it was purchased and haven't had a problem. I do however spray WD-40 on the key and lubricate all locks twice a year. A little WD-40 goes a long way. I have also seen a method for disabling the resistor at the ignition lock and by passing it at the security module. What ends up here is that the same resistor value as the key is jumpered across two of the pins of the security module and a non resistor key is then used.

Yes, this is the most radical way to eliminate all the current and future (broken wires inside ignition lock) security related issues. But your car will become more vulnerable in terms of "stoleability". I personally did not care and bypassed the system as soon as it failed (broken wires).
