Most of the time when you have a key with a chip inside you will need to go to the dealer and have it programmed to your vehicle. Depending on the dealership, you will need to bring registration and the vehicle to prove it is yours.

96 volvo 850 won't start and horn and turn signal chirp on and off


My wife ran into this problem one day when she came out of a store. Turns out the car alarm had been set off in her absence, and the alarm system had immobilized the car. The solution was to simply use the remote (rather than the key) to unlock the car. That cleared the immobilizer, and she started it up and drove off.

I lost the keys to an Acura rl 2000 I bought a new original switch with a red and a black key I already istalled but the car won't start


The keys need to be programmed to the immobilizer. Replacing the switch was unnecessary. Keys can be made to the existing locks.

My starter won't turn over because of the immobilizer


It could be the neutral safety switch if it is an automatic trans.
On most cars you can disable the alarm by locking and unlocking the drivers door with the key.
A mechanic would check for voltage at the starter, the neutral safety switch or clutch switch, and the key switch.

HAD A NEW KEY MADE AND NOW IT WON'T START


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 !!!

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.

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.

After changing the fan belt at a garage, my Mazda 6 would not start. We trried using the extra key remote, but the car still will not start. What is the problem/solution? Is there a special Security...


Hi there,

Your Mazda 6 keys have transponders built in and only the correct key I.D. will activate your vehicle's immobilizer.

I'm at a loss as to how changing a fan belt could have altered your vehicle's immobilizer system - are you absolutely certain the garage hasn't disturbed any of the electronics?

First, we need to establish whether your vehicle's immobilizer still considers your keys as valid.

- Insert Key # 1 and turn ignition to ON (do not start).
Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 1 is considered still vaild.
- quickly turn Key 1 back to LOCK position and remove key.

Wait 5 seconds...

- Insert Key # 2 and turn ignition to ON (do not start).
Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 2 is considered still vaild.

Note: if Security light does not behave as above and keys still won't start your car, then your keys are no longer validated by the PCM

If this is the case, then unfortunately unlike other manufacturers, only Mazda will be able to re-program your key's ID into your vehicle's PCM. Contact your local Mazda Dealership to discuss.


Regards,

Scott

I have a 2006 I280 iszuzu pickup the antitheft was engaged and won't start how do I fix it?


MAKE SURE YOU USING THE RIGHT KEYS. TRY ANOTHER IGNITION KEY.PLACE KEY IN THE SWITCH. TURN IGNITION SWITCH TO ON POSITION UNTIL IMMOBILIZER WARNING LAMP ILLUMINATES FOR 2 TO 3 SECONDS. IF IMMOBILIZER WARNING LAMP ILLUMINATES FOR 2 TO 3 SECONDS THEN FLASHES RAPIDLY.KEY CODE NOT RECOGNIZED.REMOVE KEY AND TRY AGAIN. IF ALL FAILS TAKE CAR TO DEALERSHIP THEY HAVE TO USE DIAGNOSTIC EQUIPMENT TO FIX CAR.PROBLEM COULD BE IN THE IGNITION SWITCH,BCM,FAULT IN THE ECM OR IMMOBILIZER CODE INCORRECT.

If you have other key try it. If it still doesn't work the immobilizer has a problem. If you deactivate it anyone with a copy of your key can put it to work. Be sure of what you do.
