Key won't start vehicle
Ford came out and made a new key and now the old key doesn't work

The 2000 Ford Expedition continued to be a favorite with drivers looking for a roomy full-sized SUV with an accent on comfort. For the 2000 model year, Ford made power adjustable brake and accelerator pedals a standard, which made the Expedition even more popular with soccer moms.
Three trim lines were offered for the 2000 Expedition: XLT, Special Edition and Eddie Bauer. The Eddie Bauer and Special Edition trim provided luxury features like leather upholstery and captain's-chair front seats; a new option for 2000 was a rear entertainment system.
Under the hood, the 2000 Ford Expedition offered two choices of engine: a Triton V-8 4.6 liter overhead cam with 240 horsepower and 280 lb.-ft. of torque, or a Triton V8 5.4 liter overhead cam that delivered 260 horsepower and 350 lb.-ft. of torque. That kind of power enabled the Expedition to tow up to 8,000 pounds.
What's the bad news? Gas mileage, of course. 12 mpg city, 16 mpg highway (Triton 5.4); it's a hefty price to pay at the pump. But many drivers think the spaciousness, durability, and comfort of their Ford Expedition are worth it!
