You have a bad door lock cylinder switch. It's usually the driver's side. Put your key in both door locks and move it to lock and unlock. One will not behave properly and make the locks cycle erratically. That's the bad one.

Four or five years ago, my wife told me this was happening to our PT. It was after a very rainy day. A day or two later, the symptoms disappeared--and have never returned.

Did you give the car a blast with water recently? Maybe a too-thorough blast at the door windows?

No word of a lie, my car did this late at night 2winters ago, and I had a heart attack! I thought someone was my backseat!!

Mine is more the interior lights come on, the locks go up and down and my car beeps that a door is open. Mine only does it when its super cold(I live in Onatior, Canada). I posted this a long time ago, I never got to the bottom of the problem. If I remember correctly, someone said it was just the weather causing it.

My car does this almost every time i start it! I start driving and the doors lock over and over and it makes beeps and flashes the interior lights. Last night I had a hard time getting it to turn over, this morning I hooked up my code reader even though the engine light didn't come on. It brought up P0562 which is low system voltage.
