If you think that in case you lock your keys in your car or lose them, you can unlock the door by getting someone at home to call you on your mobile, then press the sound from the unlock button function on your spare key into their microphone, while you set your volume to "loudspeaker" and the lock miraculously opens, then you are in for a shocking surprise! Keyless entry systems operate on an encrypted radio signal, which cannot be transmitted by a mobile phone over a voice channel. Call your road-side service provider or get someone to drop your spare keys to you.
