Key fob chip transplant?

Oh boy. If ya can it dance then that means fob is not working enough .

The pieces in fob have to talk to each other and the vehicles immo box behind glove upper box marked immo black . If from another car you have the fob and the three boxes marked one two and three which are the IMO box the sks box and the other one I put in the picture a few weeks ago if you put these three boxes from another car in your existing car and have the remote that went with those three boxes that could work . Without all that you need immo functioning scanner that's not locked out for usa

 

The small black chip and the printed-circuit board have independent functions (and they're independently registered to the car). The small black chip is what allows you to start the car when the fob is pushed into the dash slot. The circuit board allows you to lock/unlock the doors and start the car by having the fob with you.

I don't see what you'd lose by transplanting both pieces into a non-worn-out plastic case. If the non-worn-out buttons then worked, you'd be done. If not, you'd be about where you are now, but without the worn-out buttons.

 

@ChapmanF is correct. For relevance, to code a new wireless key (ie the circuit board, which is easily copied) with Techstream, you only need the unlock button working (there is logic behind this).

It’s the black ”chip” that is most relevant for smart key start though. It’s a symbiosis that is intended to be hard to copy fully by design.

 

Wow, you're saying that the actual lock button on the circuit board was ripped off? Not just the rubber cover? That's kind of awesome.
If you like doing small projects, are you familiar with circuit board repair? Do you have a hot air soldering system or similar? You could just install a new button on your board and put the repaired board in a new case. I have some old circuit boards from fobs I've replaced that should still have good buttons if you want one.
