Keyless vehicles
My DH wants to know how you get in your vehicle if it is locked when the battery dies when you have no key to open the door??

The battery in our Jeep FOB died and would not lock/unlock the doors from it's buttons. But when next to the door they would unlock in the normal grab the handle mode. Any insight to this?
Our 17 Lincoln MKX does not have a handle etc on the glove box ie no possible key. It's electrically opened by a button on the dash. Perhaps I should see if it opens without the FOB.
answer to the first question. Many of the newer "keyless" units rely on proximity detection of an RFID chip. That's in the fob. so when the car (battery working) detects the correct fob RFID it will unlock the doors if you have set it to do so or is the default.
This RFID has been around for decades and decades. Many ID badges used by companies have the chip in the badge so when you walk by the door sensor it unlocks it.
Now they are in credit cards as well.
Also current US passports have an RFID chip in them as well. They are thin and small enough to be un noticeable.
