In the old days, lost car keys meant spending a couple bucks to have the guy at the hardware store cut you a new set of keys. Today, it means replacing the keyless entry fob and a key with a "chip" built in. Both need to be programmed.
To save money, I ordered replacement fobs from an e-bay vendor (see prior post). If everything works as planned, I will save about $100 by doing so. Of course, I will have to replace the key at a ridiculous price.
