I have lost my keys and am dying to go for a ride. is there any way i can bypass the hiss, ignition an immobilizer by joining wires together or bypassing certain bits?

fob doesnt control immobilizer key has security set up --fob is designed to open and lock doors and reset alarm ---and no bypass to immobilizer

If you could disable an immobilizer system easily, it wouldn't be called an anti-theft system. The systems in late model cars cannot be disabled.

You can not just wire the wires together and have it work, there needs to be a certain amount of resistance in the circuit for it to work. And it isn't the fuel pump that gets immobilized, it's the fuel injectors that will not meter.

You can't.

Locate the immobilizer unit. This is a black box, usually situated under the dash close to the steering column. Trace the wires from the immobilizer to the vehicle's wiring harness, and where the original harness was cut, remove the immobilizer wires, and reconnect the original wires. Most fitters simply disable the ignition or starter circuit at the ignition lock wiring and this can easily be reversed.
A professional repair centre or auto electrician may only take less than half an hour for a job like this.

If the immobilizer is indeed your problem, there is now way to "bypass" this sytem. The immobilizer system has to read a frequency produced in your key to allow the veh to start. It is a theft deterent. If it could simply be "bypassed", the system would be useless as anyone could start the veh. Ususally, immobilizers kill the fuel supply, not the ignition spark. If you have no spark, you may hve another problem all together.

The vehicle requires a bypass module. If you are using one of your keys and an antenna ring to bypass the immobilizer, you still need to make a connection at the keysense wire. The keysense wire is light green at the ignition harness. If you are using the - status wire(ground when running)(light blue) from the 620 for the keysense and the immobilizer; double diode the wire.

1. Obtain a new transponder key.
2. Grind the key in accordance with the shape of the original key.
3. Apply 12V battery voltage to the ignition pulse generator lines of the engine control module (ECM).
4. Turn the ignition switch ON with the original key. The immobilizer indicator comes on and it remains on.
*The code of the original key is recognized by the ECM.
*If there is any problem in the immobilizer system, the system will enter the diagnostic mode and the indicator will remain on for approx. ten seconds, then it will indicate the diagnostic code (page 20-5).
5. Disconnect the red clip of the inspection adepter from the battery positive (+) terminal for two seconds or more, then connect it again. The indicator remains on for approx. two seconds, then it blinks four times repeatedly.
*The immobilizer system (HISS) enters the registration mode. Registrations of all key except the original key inserted in the ignition switch are canceled. (Registration of the lost key or spare key is canceled.)
NOTE:
The spare key must be registered again.
6. Turn the ignition switch OFF and remove the key.
7. Turn the ignition switch ON with a new key or the spare key. (Never use the key registered in previous step.) The indicator comes on for two seconds, then it blinks four times repeatedly.
*The new key or spare key is registered in the ECM.
*If there is any problem in the registration, the system will enter the diagnostic mode and the indicator will remain on for approx. ten seconds, then it will indicate the diagnostic code (page 20-6).
CAUTION:
Keep the other transponder key away from the immobilizer receiver more than 50mm (2.0 in).
8. Repeat the steps 6 and 7 when you continuously register the other new key.
NOTE:
The ECM can store up to four key codes. (The four keys can be registered.)
9. Turn the ignition switch OFF, remove the inspection adapter and connect the ignition pulse generator connector.
10. Turn the ignition ON with the registered key.
*The immobilizer system (HISS) returns to the normal mode.
11. Check that the engine can be started using all registered key.

If that doesn't work,You will need to go to a dealer and have the keys reprogrammed.
