SOURCE: How can I bypass a anti auto theft system on my 1990 cadillac seville?

I Have A Seville 1990, When That Happen To Me I Got The Inginion
Replaced Problem Solved. What Is Happening Is Your Key Has A Chip And That Chip Is A Resister And When The Valve Is Not Sented To The Computer It Disengages the Fuel Pump And Than Tells You To Wait. Soon All That Will Happen Is You Will Get The Wait 3 Mins And It Will Never Start, A Good Locksmith Can Take Care Of This For You And That Will Save You Some Money. Cause If You Go To The Dealer Ouch They Will Hit You Up. But I Asure This Is How It Will Happen Cause It Is How It Happen To Me
And Sorry There Is No By Passing The Computer

SOURCE: I have a 1992 cadi eldorado and the car will not

your key maybe defective or[ wrong key may have been tried.] or your battery has been improperly disconnected and reconnected . in that case you will have to go through reset procedure with proper key or call dealer with key code for replacement key.if you have the right working key , the reset is off on three times in 5 seconds leaving key on last time 4 up to 20 min. [not start ] then for 5 min.off then start if light is still on then your key is most likely defective. hope this helps .please let us know . Have a good day.

SOURCE: cadillac seville won't start

I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)

Instrument cluster illuminates intermittently on 1990 eldorado


If this is the analog intrument cluster and the entire instrument cluster is intermittently losing illumination, remove the instrument cluster light fuse and replace it with a new fuse. It is remotely possible that the actual fuse holder wires have broken due to age and would need to be soldered back together.
If this is the digital instrument cluster and the entire display is going dead, it could be anything from the wiring harness to the BCM. If it is the digital instrument cluster, I can really only recommend taking it to a reputable shop or Cadillac dealer to service.

Can you disable security system in 00 Cadillac Eldorado


Yes it can be done but if this has to be totally removed , you need to bypass the voltage to the unit and cut off the Alarm. If this is temporary you can disable on the remote key by switching off the armed sequence- follow the instructions given in your brochure or call up toll free to Cadillac support.

1988 cadillac eldorado has a new battery that only starts up with a jump charge. I think it might be the altinator or alarm ? Need the solutions


It could be the hood latch isn't engaging all the way and causing the hood light to stay on and create a drain on the battery. My grandfathers car (same year/make) had this issue and we used a bungy cord to keep it shut all the way and the problem is gone now.

I have a 1991 eldorado,it will not start back up when i go to store after about 3 to 4 min it start that's goes on all the time


Sounds to me that a starter may be going bad. This is a common problem for Cadillac.
My 1990 and 1997 Cadillac Devilles (one a Limo) does this all the time.

I would check the connections at the battery to ensure they are clean and tight, though, before going for a new starter.

How to reset a 1990 cadillac el dorado security theft system?


Not sure if it will work for this car, but turn the key to the ON position, and leave it like that for 10 - 15 minutes. I know thats how some GM cars are reset. If you have a weak battery be sure to hook a charger up to it while doing this.
