Only after market systems have valet over ride switches.
From what you said, the RX8 is shut down from
the factory immobilizer,
The IM05 bypass module is designed to circumvent this
but it's dependent on you having the original
programmed ignition key to do it.

Also, the system must not be damaged, or the code
lost from the keys or it won't do that.

Mazda may also need to reprogram the immobilizer code
for you to procede. Have that bit of info looked at
first.

try the spare key if the problem still persist .
then you have to diagnose the immo system by scan tool to know which DTC is recorded

The immobilizer essentially is a relay they spliced in series between the ignition lock and starter solenoid. All you have to do is jumper these 2 wires back together again. You can test wich wire to the immobilizer is from the ignition by watching a test light probed to the contacts when someone cranks the engine. The solenid wire is easier to trace because you can follow it from the starter.

Reset the ignition anti theft on my 2004 dodge stratus


If you are referring to the factory immobilizer, there is no resetting to be done.

The Sentry Key Immobilizer System (SKIS ) is designed to prevent unauthorized vehicle operation. The system consists of a Sentry Key Immobilizer Module (SKIM ), ignition key(S) equipped with a transponder chip and PCM. When the ignition switch is turned on, the SKIM interrogates the ignition key. If the ignition key is Valid or Invalid, the SKIM sends a PCI Bus message to the PCM indicating ignition key status. Upon receiving this message the PCM will terminate engine operation, or allow the engine to continue to operate.


For all faults except transponder faults and VTSS LED remains on steady. In the event of a transponder fault the LED flashes at a rate of 1 Hz (once per second). If a fault is present the LED will remain on or flashing for the complete ignition cycle. If a fault is stored in SKIM memory which prevents the system from operating properly, the PCM will allow the engine to start and run (for 2 seconds ) up to six times. After the sixth attempt, the PCM disables the starter relay until the fault is corrected.

Immobilizer active reset on 2006 volkswagon passat


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.

I had a new key cut for my 2004 accord and replaced the keyless entry pad. The car will not start...does the pad need reprogramed to start the car


If you car has the immobilizer system, the following might help.

The Immobilizer System protects your car from theft. A properly coded ignition key must be used in the ignition switch for the engine to start. If an improperly-coded key (or other device) is used, the engine’s fuel system is disabled.
When you turn the ignition switch to ON (II), the Immobilizer System indicator should come on for a few seconds, then go out. If the indicator starts to blink, it means the system does not recognize the coding of the key.
Turn the ignition switch to LOCK (0), remove the key, reinsert it, and turn the switch to ON (II) again.

Hope this is helpful to you.
