I experienced (experience) a similar problem only during the winter months. the problem is with the security system. Either the sensor or the module is bad(sometimes) in my case. The solution is to leave the key in the "on" position for I think 10 minutes. At that point the computer will reset the password, and after shutting off the vehicle, it will restart. Frustrating problem. Hope this gives you something to rule out at least.
