Where is the immobilizer in a kia sedona

You don't say 'why'?

Just over $100, or for cheap, go to a auto salvage yard. Don't forget the lock cylinder and key are also part of the anti-theft system and engine immobilizer.

You can't bypass alarms and immobilizers. They are there specifically to stop what you are trying to do. You have to fix the problem, not find a way to beat it. You need a transponder in the key (a chip) and you need that key reprogrammed. You need the fob.

To reset the Jeep Liberty alarm, press the control door-lock button on the keyless entry fob. Open the side door of the cab. Leave all doors closed for around 16 seconds before the Vehicle Security Light on the instrument cluster starts blinking quickly.

Push the lock button on your key fob for three seconds, until the lights on your dashboard blink. Your key has been reprogrammed, and your alarm and computer have been reset. Turn your Kia off, remove the jumper wires and close the hood.

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

Try disconnecting the neg. battery terminal. Open the drivers door and leave it unlocked then reconnect the battery back up.

may need to reset at the dealership.

That is exactly what it is. You need to find out how to reset the program. Check your owner manual. It could have it in there. If not, you should be able to call your Kia dealership and they can give it to you. You will need all your info from the vehicle.

You have a sticky motor somewhere, they tend to unlock but only half way so the motor tries to lock and unlock again, all I can suggest is get some WD40 and spray all your locks including the bootlock and all the mechanisms dont be shy with the WD40 after you have done all the locks do the keyholes etc aswell and then lock and unlock the car with the key on all locks and then lock and unlock repeatedly with the remote locking button.

Hope this helps

Dan. If you need more info about the internal door motors get back to me.

put key is drivers side door. lock-unlock 3 times in 5 seconds and then try to start. of this does not work or lock is seized, you will have to have towed to the dealer for svc

check the clip where it connect to the door pan and see if a wire is broken or that whole peace is broken where it doesnt work any more
