I actually don't want to do the "one click" to unlock. I want to do "is the key near the vehicle".

Ah, that is slightly harder. You have to hear the car's challenge and then have a decent antenna pointed at the fob, repeat the challenge, then quickly switch to rx to hear the response, them replay the response. Even with the antenna pointed at the fob you should be loud enough for the car because it is close.

You can even start the car this way. The car will keep running even out of range of the fob for safety reasons.

PSA: Don't rob from or steal cars. That is wrong. Don't be a bad guy. They might have worked hard for what they have and be really nice people.

what frequency does the car transponder challenge the key and what frequency does the key respond at?

is it a rolling code challenge like unlock/lock?

Also some new ones use ultra wide band. A super short pulse that can tell how far the fob is based on how long it took to respond to the challenge.
