i just bought my 08 G6 it has a aftermarket remote stater and alarm installed. we got the 2 factory fobs and 2 after market ones. 2 factory's will NOT work at all on the car and only 1 after market will work. the TPMS does not work on the car shows it needs serviced...... also get a svc air bag message once and a while. so my problem is we locked car with the fob and a blue light blinks by the fog light button. so we tried to unlock it the next day with the fob and it would not work at all..... the red light blinks on the fob so it cant be the battery. we unlocked car with key the lights started flashing horn going off and all lol. could not get it to go off even unhooked battery and still was going crazy. so i ran the wires from the sensor on windshield to under the dash were i found 2 boxes with wires cut everywhere and all taped up.....? i unplugged the biggest connector and it shut the alarm off............ so my question is how to i get the factory fobs to work on the car again? i know that is causing the TPMS problem also.
