This thing about holding the key to your head really did work, I used to make folk laugh when I did it. If as I think the Civic uses the radio signal type of security system, then the phone thing is an April 1st story.
Note: I have looked in the manual and it does not state how the system works.  |
About the 'head' thing. Did you first hold the key normally, at waiste height, then try with it pionting at your head? The extra distance could be down to the transmitter being higher up and having a better chance of getting to the target?
