LOL... This was eons ago. Never had this issue again as I disconnect my AntiGravity during the winter

LOL,, yeah that was the OEM Panasonic. My AntiGravity is amazing that I have had for two years. My key always works and never had that weird issue again.

Replaced the door actuator myself about a year ago. Car battery went completely dead today, and to my surprise the mechanical key was not working. Unfortunately for me no matter how many times i tried it was not opening so I had to call a locksmith.

does anyone have a diagram or video showing the part of the mechanical key hole mechanism that connects to the actuator?

I recommend if you don't drive the vehicle often or tend to take short trips, put the battery on a trickle charger. Also, I always use the Odyssey AGM batteries. Law enforcement/EMT use them. When I lived in AZ, most conventional batteries would last 1-1.5 years due to the extreme heat (we're talking 115F outside and more like 120-130F in your garage after you park a car w/ a hot engine in it and shut the door). I installed an Odyssey w/ full metal jacket inside my LX470 when I bought it...it lasted the full 4 years I lived in AZ, plus 2 more years in New Mexico where it was subject to near 0F temps during the winter. I also replaced the stock battery in my LS with an Odyssey...have never had any issues. They are pricey, though.

This is a very old thread. I replaced it with an AntiGravity Lithium Ion battery with internal battery management. It also has its own internal jump start feature. Never had any issues as the battery never loses charge. Always works like a charm.
