Ignition will not recognize the key chip and it will not start.
We purchased a used Pointiac Bonneville with the "knowledge" that the key ignition module did not recognize the computer chip in the key. The car does not always start and we have to keep turning the ignition switch for 20 minutes until the car starts. We purchased a new module unit and installed it. We were told that we would need a relearn code for this. The car started several times (without the relearn code) and now we are back in the same position where the car will not start. My husband hooked up a tester/code reader to the car and it will not read the computer. When hooked up to a different vechicle it will read it..but it is not reading this bonneville. We called the service department at the dealer and they said that the module comes with 3 parts (Module?, PCM, Ignition).
Do you think that we should replace the PCM and ignition or does this problem sound like something else?
What is the re-learn code for this module part with all the wires?
Re: Ignition will not recognize the key chip and it will...
Call a locksmith they have a reader and can tell if your key is the problem... it will tell them which keycode is for your vehicle and they can check and see if the key matches also i have a 95 ssei and the pcm was the problem with mine

The car's computer needs to be programmed to accept the key you're using with the replacement switch. There is a chip in each key, and if the computer doesn't recognize the chip, it will not allow the car to continue to run. As far as I know, only the dealer can reprogram the computer, and it may not be cheap.
First of all you need to programm all ignition keys using suitable diagnostic equipment (VAS, VAG-Com) connected to the data link connector of the car. You have an electronic immobilizer key recognition problem. Now your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel.
Everytime when you had a new key you must programm all available ignition car keys before trying to start the engine with this new key !!!
You have an electronic immobilizer key recognition problem. Your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel. Do you have this warning symbol lightning on the dashboard?
This warning lamp indicates that the engine is locked by the immobilizer system, and the engine start sequence must be repeat again.
From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car's electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.
Use another ignition key that you have, and start the engine.

This car uses a key with a transponder chip in it. The ignition reads the value of the chip thru 2 small contacts just inside the entrance of the keyhole. These contacts are known to get dirty, wear out, or become totally disconnected from the wire they are hooked to. Use electrical cleaner in the lock cylider and run the key in and out a few times to clean the lock. This is your temporary fix. The next item you may want to try ,is having another chip key made. If this doesn't work, then you will need to replace the ignition cylinder. You can try "Plastichead Keys" for these parts. They can be reached at email@example.com.
Wow...this could be a BIG problem...unless you have pretty good mechanical abilities. Your BCM (body control module) is faulty. If it's any consolation, you're not alone. There are two schools of thought as a repair and often ends up being a "trial n error" type of repair. One is to match the rating of the small metal chip in your ignition key with a resistor (RadioShack) and splicing the resistor into the ORANGE wires leading from the ignition to the BCM. The other is to replace the BCM with a junkyard piece and IMPORTANTLY make sure you get the ignition key that goes with it. Good Luck
your key reader is not reading the chip in your key you can either replace the ignition switch cost about 250 dollars parts and labor or i can tell you how to bypass it for less than 20 bucks in premium chat hope this helps
Ok, If it is the Factory Key, It should have the Plastic Finger grip at the Top. This Finger Grip has a Transponder Chip inside that Tells the Ignition that the Key is the Correct Key for this car, Go ahead and Start. These Transponders do Stop working Sometimes. If you will take the Key to the Dealer they can Reprogram the Key to work for you. But, It has to be the Factory key for this. If you have had a Key made, The key will not have the Chip inside it and will only work on the Doors. Please Rate my Response, I need all the Help That I can Get! Thanks!
Chances are the wire going to ignition broke allowing the security to start flashing.this will keep the car from cranking.On my 93 bonneville I went to Radioshack and got a 680 ohm resister,cut the 2 small yellow wires on lower steering column under dash,soldered resister to the 2 yellow wires coming from harness.Cost of repair..$1. you can read the resistance on the key by using ohm meter on each side of chip in key
