My 2011 Lincoln Town Car is possessed ... 👻

A couple weeks ago, I went outside to the mailbox, and I could hear my radio on in the Town Car. I went in the house and got the keys and opened the door. Sure enough it was on. I pushed the volume and turned it off. Then closed the door. Pressed the lock button on the remote and it locked. I have been having a problem with the entry-exit function (until I can get my FORSCAN back on there to disable it) - the seat has been making 'knocking/skipping' noise (I think the gear is stiped). Before I could get 3 feet from the car - it unlocked and I heard the seat 'knocking. Acting like the key is in the ignition (when it is clearly in my hand). I know the car will not lock if the key is in the ignition. I was a very hot day (97 degrees outside and car partially in the sun). The windows are all limo tinted and I have a sun-shade in the windshield. It was warm in the car - but not scorching. I got in the car put the key in and started it. Let it run 3-4 minutes and turned it OFF. Took the key out and got out. Pressed the button and again - unlocked and seat knocked. I opened the door and the 'key in' chime sounding. pushed radio knob and it came on. No key in the ignition. I put key in again and turned back and forth 3-4 times and removed key. Original to the car key, BTW. Removed it and got out. This time the car stayed locked.

About 3 hours later I was going to take the Town Car out for a drive and the battery was completely dead - would not even unlock the doors. The battery was just installed in DEC 2024 (DuraMax Pro (84 month battery).

I am at a complete loss as to what is going on, I take very good care of 'Aunt Lin' and now this. Some Googling say lock cylinder issue - but if you replace that - does it use the existing keys? I am looking for some advice on how to resolve the issue.

Regardless of how " New " the battery is get it load tested and replaced if necessary.
One bad battery cell can bring in lots of strange gremlins

Right now the battery is completely dead.

Right now the battery is completely dead.

Charge it back up and then go get it load tested

I still want to know what is eating the battery - and why the car is acting like it is possessed.

Post #2 then IF the battery passes the testing then you need to find a short to ground somewhere

Took battery to AUTOZONE where I bought it, and they tested it. Had a BAD CELL. Replaced Free of Charge. Now I see if the gremlins are gone. I took Aunt Lin for a drive after replacing battery...gonna need a longer drive to reset the P1000 code which set due to the dead battery. Needs a 30-50 mile trip, usually. Got home and the lock-unlock did not happen again and the car appears to have 'shut off the radio' when I opened the door.

I still need to change the ENTER/EXIT setting until I can get the seat motor/gear fixed.
