If the proximity door unlock has been activated twice in less than 10 minutes without the door being opened, then disable unlocking by proximity key until the proximity key has not been detected for more than 10 minutes.
There are times when I’m working in my garage with my key in my pocket. Every time I walk by my car, it unlocks itself, unfolds the mirrors and extends the door handles. I might walk by twenty times over the course of an hour or two and it continues to annoy me and adds wear and tear on those components.
