I’ve had wireless hire cars. Horrible things, never sure where they key is and tend to come with “features” like automatically locking and setting the alarm if you walk away from the car
And then they unlock automatically when you walk back to them. Much more convenient than having to manually fumble for the lock and unlock buttons. Not sure what the problem is here!
Alarm goes off as the car isn’t empty
Never had this happen in my experience. Sounds like an issue with an aftermarket alarm?
Park at a convenience store. Go in to get a coffee. Leave friends in car. Friend decides they want a coffee too. They open the door-- car alarm goes off. I'm sure some cars are better programmed but this has happened to me in several cars. (For the record, I still prefer keyless!)
Having a keyfob at all seems awkward and old-fashioned after driving a Tesla. Same goes for the start/stop button.
