Since both remote entry batteries are dead on my current car, I cannot try at the moment. I'm not really concerned if I can do it on my current vehicle anyway. My coworker swears this is true story BTW* , so hold on to your seats.
One day we're in the office and my coworker, we'll call her Martha Kaclackin, comes up with this crazy story about accessing her vehicle after locking her keys in the car. She tells me "I was at the mall the other day and locked myself out of the car". She says she then phoned up her husband via cell, so that he may come to the rescue. Mr Kaclackin too busy watching the game, told her to "point the cell phone at the car honey". He then points the remote from his keychain at the phone he's using at home. She does what he says, and instantly the lights flash, and a click is heard. She said she hopped in her car and drove home.
Has anyone ever heard of such a thing? And even so, will this be possible with the new E60?

I remember reading a couple of years back that (can't remember brand of car Merc or Bimmer) The engine changes the security code each time its started via a signal transmitted by the key. Apparently it was some form of security system built into the engine. If the statement is true would this affect the ability to unlock the car via the phone as my friend claims she and her hubby did?

There is a similar link about locking the keys in the car, I felt this was different, hence the starting of a new post. I did provide the link anyway.

Lastly, anyone want to be the class guinea pig?

I've heard of this before but have never tried it.

We're still in the month of April, and I don't believe it unless someone here on forum proves it.

I would expect cell phone microphones to filter and transfer signals only in the audible frequency range.
Hence no it should not work.

This is strange because I was telling a friend of mine about this just this weekend. I swear this works on my Honda Civic (now my wife's car :-) but I have never tried this on my e60. I should give it a go sometimes and see. BTW this doesn't work on all cars because it didn't on my friends Ford Focus.

Probably a tall tale, but the one about aiming your key fob at your head to increase the remote's range seems to be true...

Completely forgot about that trick.

With regards to the cell phone, perhaps this is similar to how Onstar is able to unlock your car remotely??

You're kidding right?

Sorry... I am not aware of any GSM/TDMA/CDMA cell phone that will work as a radio repeater. If it did then you should also be able to open your garage door in the same way. Sounds like BS to me.

The key to your head trick works because you become a ground plane for the antenna. At least this would work on older keys that have the fob and metal shaft as the antenna. You can use any part of your body such as your hand just place the key to the body part at a 90 degree angle to extend the range.

"It might work if remote entry system signals were sound-based, but they're not. The remotes transmit an encrypted data stream over a radio frequency signal -- a signal that can't be relayed by cell phone."
