(Security) light does not come on. Waited 3 minutes. tried to start car but it won't start. Tried different key, still won't start.
1992 Cadillac El Dorado does not start due to anti theft system. Any suggestions on 1992 Cadillac Eldorado
If I remember correctly the '92 Cadillacs have the resistor pellet in the key. Because you already tried a different key the problem could be a broken wire from the ignition tumbler to the connector under the dash. Have someone test the resistance of the tumbler and replace if needed.
agree with justin
