Howdy folks, recently I’ve noticed some weird things happening with my 01 LX470.

It’s a backup vehicle for me so it doesn’t get driven so much these days. For the last year or so if I leave it for more than 48 hours the battery dies and I have to jump it. Whenever I jump it my alarm goes off. Then I noticed 3 weeks ago that if I lock it from the drivers door instead of with the remote, the battery will hold a charge just fine.

I also noticed that when I press the lock button on the door with a door open, the truck doesn’t auto unlock to keep me from locking my keys in the car. And I haven’t tried with the front doors, but if a rear door is open it beeps if I try and lock from the remote. The tailgate doesn’t do that.
 
It’s possible the lock motor is old and not completely latching. That could be causing the issue. Have you replaced the motors before?
