Took my newer Camry in to have a new key 'programmed' so I'd have a spare. They did that job, then they re-programmed the TPMS (Tire Pressure Monitoring System) threshold so that it triggered a week after I got the car back. I sighed heavily and replaced their leaky valve core, set the tire pressure to factory spec and then re-adjusted the threshold back down to factory spec. It's worked trouble - free for a couple years now.
Dealer Service. Feh.
