yeah mine was just worn out with just shy of 200k on the clock. on bumpy roads, the keys would often fall out and hit my leg, so i tried to keep my keychain as minimal as possible - car, house, and that's it. everything else (lockers, work, etc) i kept on a separate keyring. for a brief time, my dad had an 88 camry wagon, and its key would unlock the door but not start mine. my key never worked in anyone else's car though.
drivetrain was great though, and easily got 40 mpg on the highway. but for some reason, cruise didn't work above 80. if you were going say 85 or 90 and hit SET then let off the gas, it would coast down to 80 and hold it there. it held whatever your set speed was as long as it was 80 or less. that was really annoying driving to/from dallas, even before they raised the speed limit to 75. typically, if you're not doing 90, you're going to be run over.
