This is how bad my immobilizer was.
It didn't work at all and the chip circled in red was the chip I tapped into and copy its memory onto the other used immobilizer's memory. The only problem I have now is the security system doesn't fully engage (maybe because the pigtail is partially destroyed). When locking the car the the alarm sounds twice, and the red light flashes twice every 10 seconds. Coincidentally my remote stopped working after a few weeks, light flashes but don't send a signal.
Regarding the immobilizer the chip can be soldered over to a different immobilizer or I can explain how I reprogrammed it, but there are professionals here (wish I knew earlier) who can do it better than me.
