depending on the amount/location of damage to the vehicle you could have damaged the wiring harness leading to blown fuses, or damaged important sensors/relays that, if damaged, wont allow the vehicle to start. or you could have tripped the rollover switch which cuts the power to the engine in the event of a rollover to help prevent fires. but can be set off if damaged or hit hard enough. Start checking fuses and wiring on the damaged part of the vehicle. I hope this info helps.
It sounds like a security problem. The same thing happened to a friend. He had to take the key to the dealer. It cost about $125. I think they turned the alarm off.
The light is most likely on due to some type of electrical fault within the computer controlled system on the car. You will need to have the vehicle scanned for codes to resolve this.
Hi Joe here,
The problem with your a/c is a sensor. Most likely the pressure sensor. You need to have the vehicle scanned to find out which sensor it is.
