You're as wrong as I am.
If the safe were already open - it couldnt then 'open' again.

But yes, the original post shoudl have said 'at' instead of 'in'.

 

i have a Auto watch, with two alarm fobs. i taken one to work today, as needed my keys and left my fob at home, lets say i was quite far away, easy 3 miles. anyways, rang the mother up as she locked the car and left the window open a little to slide the key inside. called her and told her to hold it in different places, such as around the car, near the dash, near the door, even got a metal coat hanger and place it from the phone to the car, and nothing come of it.

 

Fuck me we have a clever one here

 

funny that

 

The only way it could possibly work even slightly would be if your phone was a very poor design and demodulated and re-transmitted it on the GSM band. However, you would be extremely lucky for the receiving phone to manage to re-modulate to the correct frequency and re-transmit, all entirely by accident.

Pre-amps and power-amps always have low-pass filters in their circuitry to improve their performance in the audio band, limit power usage and protect themselves and the speaker from damage. This would stop any un demodulated RF signal from passing through the circuitry. Furthermore, the bandwidth available for each audio signal on a GSM network is not sufficient to transmit an RF signal. Some audio circuits do unintentionally function as rf demodulators though, but not those in phones as if they did so every phone call would sound like a fax machine!
