Strange Unlocking Situation 2

[MacG]

I decided to start a new thread with links to the old one for reference so I do not get any false reports of replies referencing AOL from the mod :)

After a nearly six month hiatus, it did it again today. Walked past the rear passenger door,
door beeped, door unlocked. I'm sure that I did not hit the unlock button on
the key while walking. Strange, but no harm since I can always relock the car.

Sorry to drag up such an old thread but this has happened
to me about 4 or 5 times except I am approaching from the front. We bought a 2007 ES350 from the dealer in November 2014. If you still have this car has this continued? Did I buy your car? ;)

The only things that come to mind would batteries in the fob and perhaps the car battery as Lexus said that the car's battery is showing wear. I have not seen any signs of that and I assume it means that it just has fewer cranking amps.

Any help would be appreciated.
