Greetings and Welcome to Just answer.

here is the reset.

Turn the key on, with the engine OFF.Try to start the engine, then release the key to ON, Engine will not start. Watch the security telltale, after about 10 mins, it will turn OFF.

Turn OFF the ignition, and wait 5 seconds.

Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. You must turn the ignition OFF before attempting to start the vehicle.

 

Start the engine .

 

 

If this works, then you may need to replace the passlock sensor or bypass it.
