This may sound very simple . . . it may annoy you even . . .
I'm asking so that I can think of the possible problems.
If you can, describe in detail everything that you observe from the moment you stick the key in the ignition. When you push the key in the ignition, keep the door open . . . listen so that you can tell us if you hear the door chime or not.
Describe in order everything that either happens or fails to happen as you turn the key . . .
Just trying to help . . .
