key fob wont turn over
So my primary key fob wont turn over... it unlocks and locks my car but when i put it in the key receiver it does not turn... my spare key turns the car on just fine... anyone experienced this problem? what can be the cause of this ?

First, i would check the vehicle battery. That may not be the culprit, but a weak battery can cause all sorts of electrical gremlins, including "killing" a key. For example, leaving the key in the ignition and then the battery dying can ruin that key. There is really no way to re-sync a key - once it gets locked out, it's toast.

Nope. Most all SRS errors are "persistent" and can't be cleared until the underlying fault is corrected, and then the error is reset via SDS (or other high-end scan tool - not generic OBDII).
