Recently got this car and the key chip stopped working, green key light on dash is flashing. called pop a lock to get a new key and reprogram it to the vehicle. Every Time he would try to program it, his system would just kick him out, now with the original key, the ignition lock cylinder will not turn to ON or ACC. i bought a new ignition lock assembly with new immobilizer and they key turns and everything but when i try to program the immobiliozer to the vehicle it will say " no communication to ECU'' battery is good and all fuses are good. engine cranks just fine. unsure of what to look at next. Maybe time for a new ECU
