2019 Ford Ranger Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2019 Ford Ranger does not support DIY, on-board key fob programming. This means you cannot program a new key fob yourself using a sequence of actions like turning the ignition on and off. The vehicle's security system requires a specialized diagnostic scan tool to add new key fobs.

This is a common security measure in modern vehicles to prevent unauthorized key duplication and theft. The scan tool communicates directly with the vehicle's immobilizer system to register the new fob's unique identification code.

Battery replacement

1. Locate the release button: On the side of the integrated key fob, you'll find a small release button. Press it and pull out the emergency key blade.
2. Separate the fob halves: With the key blade removed, you'll see a small slot. Use a thin, flat-head screwdriver or a coin to carefully pry the two halves of the fob apart.
3. Remove the old battery: Note the orientation of the CR2032 battery (positive side usually facing up). Gently pry it out.
4. Insert the new battery: Place a new CR2032 battery into the slot, ensuring the positive (+) side is facing the same direction as the old one.
5. Reassemble the fob: Carefully snap the two halves of the fob back together until you hear a click. Reinsert the emergency key blade.

Where to buy a replacement fob

• Ford Dealership:

  • Pros: Guaranteed genuine OEM part, often comes with a warranty, and programming services are typically included. You'll receive the exact match for your vehicle.
  • Cons: Most expensive option. A new fob from a dealer can range from $200-$350 or more, not including programming labor.

• Automotive Locksmith:

  • Pros: Generally more affordable than a dealership. Locksmiths often have access to both OEM and high-quality aftermarket fobs. They can also cut the emergency key blade on-site and program the fob using their diagnostic tools. Mobile locksmiths can even come to your location.
  • Cons: Quality of aftermarket fobs can vary. It's crucial to choose a reputable locksmith.
  • Price Expectation: Expect to pay $150-$250 for an aftermarket fob, cutting, and programming. OEM fobs from a locksmith will be closer to dealer prices but with potentially lower programming costs.

• Online Retailers (e.g., Amazon, eBay):

  • Pros: Potentially the cheapest option for the fob itself. You can find both OEM and aftermarket options.
  • Cons: You're only buying the physical fob. You'll still need to pay a locksmith or dealer to cut the emergency key blade and program it. There's also a risk of purchasing a counterfeit or incompatible fob. Always verify the FCC ID (HS2T-15K601-AA) and part number thoroughly.
  • Price Expectation: Fobs can be as low as $30-$80, but remember to factor in the additional costs for cutting and programming (another $100-$150+).

If on-board programming isn't supported

As established, the 2019 Ford Ranger requires a diagnostic scan tool for key fob programming. This means you will need to engage with a professional service:

• Cost Expectations: The total cost will depend on where you purchase the fob and who performs the programming. Generally, expect to pay between $150 and $350 for a fully functional, programmed key fob, including the cost of the fob, key cutting, and programming labor.
• Immobilizer Transponder: The 2019 Ford Ranger uses an integrated immobilizer transponder chip within the key fob. This chip communicates with the vehicle's immobilizer system. When a new fob is programmed, its unique transponder code is registered with the vehicle's computer. If the transponder is not correctly programmed, the vehicle will not start, even if the key blade opens the doors. This is a crucial security feature that prevents the car from being stolen with a simple mechanical key copy.
