[Solved] Key fob malfunction
2012 Jeep Compass. Recently my headlights come on when I unlock my door with my key fob. Also while the car is not being used the headlights come on for a couple of minutes and then go off. This happens periodically for no reason. When I take the battery out of the fob this stops the problem. I have put a new battery in the car and in the key fob. If I don't drive the car ( i'm retired) for a few days, with the battery in the key fob, my batter goes dead. Can you help.

Sounds like a malfunction in the receiver or computer. Try doing a system reset.
disconnect the negative battery terminal (being careful not to let it touch anything else). Press and hold the brake for 10 seconds or so and then hook everything back up. (note: you may lose various settings like radio stations, seat position, etc.)

so do mine, but that's a normal function. It's configurable in the DIC.
Which battery goes dead?
Do you have a second key fob and if so, does your vehicle respond normally to it?
sounds like a bad remote
I have searched online for an answer to why your headlights turn on and off randomly by themselves when the car ignition is off. I have zero expertise in this area, just trying to help and learn something new. If the advice given by @mmj does not solve the problem I have read several suggestions that advise checking for a faulty headlight relay switch.
I thought it was fixed, but now my lights come on at night and daybriefly, go out, come on, putting a drain on my battery. If I take the batteries out of the key fobs it doesn't seem to happen. I have disconnected the negative battery cable, let it sit for 20 minutes and then reconnected it. Any idea why the key fobs are causing this problem?
