1. Just the Key:
* If you've lost your key or it's broken: You'll need a new key *cut* to match your vehicle's ignition. This is the cheapest option.
* How: You can go to a locksmith, an automotive dealership (Ford dealer is ideal but more expensive), or an auto parts store like AutoZone or Advance Auto Parts that offers key cutting services. Some hardware stores may also offer this. They'll need your vehicle's VIN or the original key (if you have a spare). They may also need to check the ignition cylinder to ensure a correct match.
* Cost: Expect to pay anywhere from $10 to $50 for a simple key duplication, depending on the type of key (standard or transponder) and the location.
2. Key and Transponder Chip (More Likely):
* Your 2000 F-350 likely has a transponder chip embedded in the key head. This chip communicates with the vehicle's immobilizer system to allow the engine to start. If your key is broken, lost, or the chip is malfunctioning, simply cutting a new key won't work.
* How: You'll need to obtain a key that includes a new transponder chip. A locksmith, dealer, or some auto parts stores specializing in this can do this. They typically program the chip to your vehicle's computer system. This involves plugging a device into your vehicle's diagnostic port. The process is more involved than just cutting a key.
* Cost: This is considerably more expensive, ranging from $50 to $200 or even more, depending on the complexity, location, and the need for additional services like towing (if your vehicle is immobile). Dealerships will generally charge the most.
3. Ignition Cylinder Replacement:
* If your ignition cylinder itself is damaged or worn out, replacing the whole cylinder is necessary. This is more expensive and labor intensive.
* How: This is a job best left to a professional mechanic or locksmith experienced with vehicles. They'll remove the old cylinder and install a new one, ensuring correct key operation and potentially replacing the ignition switch as well.
* Cost: This will likely cost several hundred dollars, potentially upwards of $500+ due to the labor involved in removing and reinstalling the ignition cylinder. The cost of the cylinder itself will be added to labor costs.
In Summary:
* Cheapest: Duplicating a simple key (if you have a working spare and it's just a copy you need).
* Mid-range: Replacing a key with a transponder chip.
* Most Expensive: Replacing the ignition cylinder.
Before doing anything, it's advisable to get at least two quotes from different sources (locksmith, auto parts store, and maybe a mechanic) to compare prices and ensure you're getting a fair price. If you're locked out of your truck, calling a roadside assistance service might be a faster (but more expensive) initial solution.
