I've heard that bit about the ignitions and heavy key rings, but have never had the problem.

I have always only carried ONE keyring. Long, long before I knew I had ADD, it was the only way to have the key I needed with me. I have 16 keys and a screwdriver on the ring. I drive a decrepit old 1985 Chev Cavalier with only five windows on the odometer, so I don't know how many times it's gone around.

You guys must be driving those wimpy, namby-pamby vehicles.
