I was once shown how to bypass the alarm on a Toyota where you turn the key on, but without attempting to start it, then cycle off, on, off, and on again, then the alarm turned off and it would start like you turned it off with the remote!
There should be a way to bypass the system on my 2002 Elantra GT as one remote (the one I have, she gets the good one

) is seriously worn out and some day soon I believe I will be stranded and she will be home with the good remote and no way to get to me.
Anyone know?
