Question about immobilizer chip

Does the chip need to be in the vicinity of the ignition all the time?

Let's say, for some reason, I ripped out the chip from the key. If I take that key and try to start the car, of course it won't work. If I put the chip in the ignition area and start the car, it will.

Now my question... what if I started the car with the key and chip, but I suddenly pull the chip away from the ignition. The car will not die, correct? I just want to confirm before I throw more cash into the money pit.

Thanks in advance.

I'm pretty sure you're right. I think the chip is just for the starter and not the ignition. That's why if the car is standard you could probably jump start it. You might want to try and jump start it without the chip and see if it works. If it does, then you know you don't need the chip. Or, you could just try and move the chip and see what happens.

What are you working on? Keep us posted.

You're probably right, but what are you planning, Kev? And how do you plan on getting the chip out of the key? This sounds shady

I know the car cranks if direct power is given to the starter... but we never gave power to it long enough to see if it started without the key (I doubt it would).

Nothing shady is happening. I just want to make sure a turbo timer works.

Thanks guys.

Although thats a point I would not have thought about. For the TT to operate you need some ignition control. Nice catch.

Re: Question about immobilizer chip

i didn't check those other posts, but the answer is:
the chip only starts the car. if it's in the vicinity of the ignition, the car will turn on. once on, you do not need hte chip anymore. this is also how you are able to remote start cars with immobilizer chips. a black box that holds an extra key is placed somewhere hidden in the car. when you activate remote start, a pulse is sent to this box, which activates the chips code. in that split second that the chip is active, the car will turn on, the pulse will shut down, the chip will deactivate, and the car will stay on.
you are thinking, someone can easily find your key, and just drive away with your car. 2 choices for this:

1) rip the key off the chip and just leave the chip in the box.
2) do a good job at hiding it.

old fashioned way of doing remote start prior to this bypass module was taping the chip around the ignition. that left the chip around the area 24/7. the problems with that arose when you would turn on the car with your key, and the car would then see 2 keys. the one taped around the ignition and your own. this created problems.

again, i didn't bother lookin at the other threads, so this may be repetitive, but a pretty savvy installer told me all this, and he knows his sh*t.

Thanks! I'm not worried about remote start. What the turbo timer does is let the car run after you have stopped the car and taken the key out.

So, since the immobilizer chip only affects startup, the chip will not need to be in the vicinity when the turbo timer is working.

I did my remote start in this method, but removed the chips from both the keys (that's how I got one anyway) so I would not have this problem.
