Key fob question
 

If I leave the key fob on my just picked today,2010 triple black 19k roadster, in the car (garage kept) over night will I be draining the batteries in either the fob or the car

Nope. no different then it being in your pocket every time you drive your car.

Thank you...

But why would you want to leave the FOB in anyone can than start you car, get in your trunk, etc.

I leave the car in the garage with an NSX. Keys are on both of them and I leave the keys in the Z4 Coupe left on the driveway. I haven't locked my front door for 15 years... I live in a really safe area.

However, I have had the Z for two weeks. I have been leaving the key fob in the car and the battery wore down! I think that the key and the car are constantly communicating. I'm not leaving the fob in the car anymore.

I'm coming to your neighborhood!!!

I'm not sure if the car/fob do more communicating when in range or not but you should be able to check by putting the fob in a metal box. The "Press Brake/Clutch" light should go off if the box is doing a good job of shielding the fob. See if battery drains.

That's a great idea SouthArk!
