Ok, so it is a random question but was wondering if the car could drive maybe 3 miles away from someone holding the key. I ask this question because my mother was dropping me off at work and I forgot to give her the keys to her vehicle, she has a 2011 BMW X3, yes I know, not a Lexus but I found that I still had her when I stuck my hand in my pocket that was maybe 5 minutes after she drove off. I immediately called her to let her know, to my amazement the car did not stop and she was about 2 miles away. Sorry but I find that amazing and wondered if the GS could accomplish the same thing. All answers are welcome.

 

I would guess the key is only a perimeter functioning part of the security system. It doesn't surprise me that once security/ID is obtained the rest of the electronics take over. If not, imagine if the battery in your FOB went bad on a long drive -- that could get ugly

 

you only need the key to start the car. once its started you can drive anywhere.

 

yeah you could drive coast to coast without the key if you dont turn it off

 

Exactly you need the key to turn it on once its on, its on and running aslong as you dont turn it off, cause thats when you need the key again

 

Ok, always thought that beeping sound meant the imment death of the engine cutting off in the GS.

 

What everyone else said, however I learned they hard way. I was warming up my car in the garage and went inside to grab a bottle of water. The car started beeping as I walked away, and assuming the car was going to shut off I threw the keys on the sun roof. Proceeded to come back to my car, drove off and didn't realize my keys were on the roof until I heard them slide off as I accelerated onto the freeway. FML.

 

lol... FML, love that website.

 

You can drive to russia and back as long as you don't turn off the car

 

Lol that really had to suck.
