Default Key Fob replaced and then Car won’t start.

So, I’m lost here. I got a replacement key fob and switched the key and the circuit board to the new fob. Went to start the car and it tried to start on first two attempts and then nothing on the third. Tried to research on my own and thought that it was the Skreem. I sent the Skreem and the ECU to precisionECU for them to do the immobilizer fix. Got them back, installed them, and now the car still won’t start. Remote still unlocks and locks doors. I hear the fuel pump engage, all the lights on the dash are on, and after a few seconds the fan starts. What did I do wrong? Is the chip for the key not on the circuit board? Did I miss it and throw it away possibly? Does it matter if the Skreem is immobilized? Thoughts? Advice? Thanks in advance!

No, the chip is small and in the front of the FOB. I hope you didn't throw it away or loose it. There is a how to here on the forum. Use the search function.

Contact Needswings or SOS - you will need to yank the ECU and SKREEM and send them to them. They can make a key for your car, but I'd go with a SKREEM Delete, where the car no longer needs that little chip to start. This decreases security a bit, but our cars are not big theft targets anymore. This way, you no longer need the RFID chip and the car starts just by turning the key.

I understand this will cost around $450-500 but once you do this, you are DONE with SKREEM issues forever.

Pizzaguy, that makes me feel better. That’s what I paid precisionECU to do. I have contacted them and they asked me to check my install and if it still doesn’t work, that they will let me send it back to have them check it out. Hopefully I just didn’t push one of the connectors in all the way....

It was a very expensive mistake but I just unhooked everything and when I plugged it back in, it now works. So, now I can safely recommend PrecisionECU for doing the Skreem delete. Thanks guys for your input. It helped me.....
