Key fob and alarm issues. I locked my car with my key fob as usual, when I went to unlock it with my key fob it wouldn't unlock, the key fob wouldn't respond to any inputs. I used my key to unlock the door and of course the alarm went off with the horn and lights flashing. This is a factory alarm. I tried to start the car and nothing. I pulled both horn fuses from underneath the hood to quiet it down. I changed out the battery on the fob and that didn't work.
I disconnected the battery to see if it would rest the alarm for ten minutes, and it did to a point. I tried using the key fob again to see if the key fob worked and it didn't for about a minute after reconnecting the battery, but then work correctly. On the DIC display it said Alarm Activated by Hotwire. The car did start after this finally. But after driving for about ten minutes on the highway the Airbag fault message came up for a few seconds, the speedometer dropped out, but came back and then the low tire light icon came on. The tire icon light went off after about two minutes of driving. After driving for another ten minutes the ABS fault message came on along with the X Contact dealer and the tire light icon. This time all the gauges dropped out for about twenty seconds and the came back to normal. After driving for another ten minutes the low tire light went off. The car drove fine the whole time. I haven't tried the key fob or starting the car since I got home. The car battery is only two years old. Sorry for the long post, hopefully it's something simple.
I left the car unlocked last night, tried the key fob this morning and it didn't respond. I tried starting the car and it wouldn't start. Just a whole bunch of waring messages again. Abs fault, brake, air bag, contact dealer.
