After eleven years and 165,000 miles worth of locking and unlocking, the remote for my cars alarm is about to give up the ghost. I changed the batter, but that wasn't it, but switch itself seems to be wearing out. Since I don't want the last thing it does to be to arm the alarm, I've stopped using it and have reverted to the old fashion key. The lock hasn't really had any exercise in years so it was a little resistent at first. The design itself is nice. When you turn the key clockwise it locks all four doors on the car. The first rotation counter-clockwise unlocks just the driver door and a second turn unlocks the rest of the doors. Not that big a deal, and most cars probably do the same thing, but it's one of those little detail refinements that means that someone was really thinking about it.
