Yeah what they said. Door lock remotes operate on RF
(radio frequency
), while what's coming out of the phone speaker is AF
(audio frequency
). Try it with your TV remote from another room using the 2 phone technique...it won't work there either, and if it does, it's because the TV is still close enough that it's picking up the RF signal from the remote itself, not via the phone.
Man, some people will believe anything! I got a bridge I want to sell you Janelle!
Just to clear thing up a bit, remote car door locks are indeed RF with an encrypted code that is accepted
(hopefully
) only by the receiver in you car. That is why you can unlock your car doors from inside a building or from any direction around your car for that matter. This will not work using a cell
(or other
) phone, just not possible. About using a TV remote, it would not work anyway, *most* TV and other electronic components use IR
(infrared
) to transmit the hex or binary code from the remote to the device. This is way you need to point the remote at the TV or other device you are trying to control. Without having a LED to send the code to the receiver on the TV it would just not work. Some Satellite receivers use an RF
(radio Frequency
) to transmit the signal, and that is why it may not be necessary to point the remote at the Sat receiver.
TV's in the early to mid 70's used a audible tone for basic functions like power, vol +/- and ch +/-. This could really screw this the dog in the house, when I was a child, ours would cock his hear to the side and run up to you while using the remote!
And yes, I am also an electronics
(Home Theater/Stereo/Computer
) geek!
