Ok..
Your vehicle is equipaded with Factory Anti Theft System.
Called Pass key II . If the mechanic found the Code
Pass key error....
Is there a few test to Do. to know exactly the problem.

1--- check if the Old and New key Are equipaded with a Little thing (Chip or Ressistence) in the center of the key.
If not you need a key with the chip. and the correct Ohms.

2. If you just replace the battery,
Full charge the battery Attemp to start the vehicle and leave the key in run position for exactly 11 Minutes, Them turn the key to off position for 30 seconds and try to start, if the vehicle start . you did the prosses to program the key.

If the vehicle not start.
Some times this procedure will require Up to 3 times to setup.
Or more with intervals of 30 minutes,, But if not start.
Remove the lower cover of the steering column. and the the Connector orange with 2 white wires shielded with a orange cover.
NOTE.. Be sure to not Confuse with the Yellow wires and connector, They are for the AIR BAG. Dont use a Convencinal Test light on any of the Mentionated wires....

After you find the wire and saw everything ok.

3-- You will need to remove the Ignition Lock cylinder.
The ignition lock cylinder is use 2 white wires shielded with orange cover, On 90% of the cases one of the wires come broken. and the ECM loss the comunication with the Chip incrusted in the key..

Car does start


I would start with the key switch and checking the major fuses in the engine compartment. It sounds like the key switch is not moving past Acc or it does not have power for the major circuits.

I was sitting at a stop light and the car died and smoke came from steering column ever thing else works light radio etc but when you turn the key there is nothing no idiot lights no miles nothing the car...


Maybe the ignition switch burned up. A lot of juice travels through them and it has happened.
What is confusing is, lights will work without the switch. You should be able to turn lights on without the key in the ignition. But a radio normally needs the ignition turned to ACC (accessory) or ON. And some when left on don't turn off with the key off until the door is opened.

Possibly the ignition melted and is affected to where the radio still gets power as if it was in the ACC position

Engine starts for 3 seconds and then shuts down, radio,locks,trunk release,interior lights do not work, clock/radio display shows time but nothing from radio


Hi,
This could be a tricky one - so just go through the options methodically untill you effect a repair.

If it has an immobiliser fitted - try using another key. Sometims the chip in the key fails.

If you did anything prior to this problem - jetwashing, using a mobile phone near the steering column, serious work etc - try these areas first.

Check alternator function.
Check fuses.
Check fuel level.
Look for leaks.
Check belts condition.

It is behaving like a major electrical fault. Check the BIG fuses in the engine bay fusebox. After this - check that the ignition switch is supplying a switched live feed when in the "on" position.
It could be a faulty switch contact. Possible if you have uprated lights somewhere.

This system can be scanned for faults, you need that scan done to see what is wrong in the electronics, this takes a dealer level scan tool.

95 buick park ave car running radio off,igniton on accradio works


Who ever took the radio out is guilty. The power wires must have been reversed. One is supposed to have power all the time, (memory)and the other just when your ignition is on. Apparently, they got mixed up.

sounds like your passlock sensor on the ignition barrel is faulty. you will have to go to the dealer to have it replaced because of the programming after replacement.
