True it should still crank(turn over). That sounds more like the Passkey system or the key cylinder needs replacing. Many posts about that here.

I have only had my Intrigue not start one time in 5+ years of ownership. After disconnecting the battery it started fine. Keep an 8MM box wrench in your center console at all times for that just in case scenario.

Post back and let us know the verdict once your sensor is replaced. It helps build confidence in others reading these posts.
