    Just started making an otherworldly noise coming from drivers door area when unlocking with key fob or switch on door. I am not sure how to attach a small audio file I made with my iPhone. I am worried something is in the process of wearing out and I will be stuck, locked out. Its not a normal beep tone. I do not have an aftermarket alarm. Tried uploading but the file .m4a extension isn’t supported. Thanks in advance!

    The power lock actuators wear out. I understand they're very expensive at Toyota, but the no-name ones are much cheaper and work properly. Any neighborhood mechanic can do the repair, there's nothing special about these.

    Yes - I think that’s it. Quite loud too!

    I see what you mean about Toyota prices! Yikes. They want more than what I paid for the entire car

    there's a lot here on diy, and expensive at a dealer. but you should probably replace it at some point before it fails.
