A friend came over with a late-model BMW and we went to a concert and when we got back, her remote wouldn't open the door. She tried over and over as she panicked and thought she'd not be able to start the car. I couldn't tell if the remote's battery was dead, or the car's. I told her I would jump the car, but she said, No, it won't work.
Then we discussed if I had a replacement battery for the remote. I have
2032's but nothing bigger, and she says her remote uses a bigger one. I said, Isn't there a key in your remote, and she said "uh" and brushed it off. I said, Why is there a keyhole if there is no key?
So she finally took the key out of the remote and opened the door but as she did that she said the car wouldn't start because the battery is dead.
But of course it did.
She admitted that she panicked.
What do you call the arrangement between the car and the key or the remote where the car can tell if the key/remote is nearby, even though the key/remote has no battery or a dead battery???? Is there a technical name? A poplular name?
I have the same thing in my 2005 Solara, that there is a chip in the key, but no battery, and the key has to be within a few inches of the keyhole. She has no keyhole (other than in the door), but the remote has to be near the driver's side of the dashboard.
In my case, I can make a copy of my key on a non-chip-key blank, and uses it with a broken chip key, if for example, I have the handle of key on the same keyring. The first key turns inside the keyhole and the handle makes the car happy.
