Try getting a new key made I had same problem.
I've heard it can be a few things: key, ignition cylinder, bcm. It's something to do with the PASSLOCK. I installed an aftermarket remote start system with a security bypass module and I haven't had any troubles with mine since. This procedure used to help some of the times my car wouldn't start: Turn key to off Turn key to on (do not try to start the car Just on) Security light should be flashing After 10 minutes, turn key to off for 5 seconds during the 10 minutes, do not open any doors. Turn key to on for 2 seconds Start car
