I a new owner of a used 2007 ES350, about a week ago I had to change out the battery on the car. Since then something weird is happening now. The doors are trying to lock by themselves. I can hear the clicking nose in the doors while i'm driving . I got out the car this morning with my key fob in my hand, but lef tthe car running to take my daughter into daycare, the doors automatically lock and could not be unlock by the key fob nor any of the buttons on the doors. i had to use the key to open the doors. Has anyone had this happen to them before? I being told that I should replace the battery in the key fob.

 

I think I've seen something similar on this forum before. If I remember correctly, it was something to do with the car battery.

I know you said you installed a new one but make sure the connectors are all secure, the battery is actually good and that the charging system is working properly.

 

I bet it's the actuator.

 

Maybe give this a shot:

With the car running in park or neutral hold the lock button down for 5 seconds...? Easy enough to try...
