My car "wakes up" (you can hear the Bose amp fan in the boot start up)
when you walk by the handle with the key,

But the car won't unlock until you put a hand under the handle.

The lock buttons fail often but the button has only one moving part.

I have found these handles can be reanimated if you unplug them, and clean the plug and handle contacts with contact cleaner. Water gets into the plug, and screws with the very small electrical resistance range the handle uses to work.

Under the rubber button is just a spring and a metal plate the touches a contact on the handle body.
