So every once in a while I have this weird issue with my 2002 X5. Nothing major, but I want to get to the bottom of it. It happened again for the first time in a long time today. Basically I was walking to my X. I hit the unlock button and the car unlocked normally. I get in the car, and start up the engine, and the hazard lights turn on. So I turn them off and begin to drive, and I push the Door lock button, but it doesn't work. I get home, I shut off the car, get out, and then hit the lock buttom from my key. The system arms, but the doors are unlocked! Then I just unlock it again and lock and it seems to be fine. This issue happens exactly the same way every once in awhile.

Does this mean anything? Any idea what causes this?
