2015 Ford Explorer Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2015 Ford Explorer supports DIY on-board programming for additional key fobs, provided you have two previously programmed "MyKey" keys for the vehicle. If you only have one working key or no working keys, a dealership or locksmith will be required to program new keys using a diagnostic scan tool.

To program a new key fob (with integrated key blade) if you have two existing programmed keys:

1. Insert the first previously programmed key into the ignition and turn it to the "ON" position for at least three seconds, but no longer than ten seconds. Then turn the key to the "OFF" position and remove it.
2. Within ten seconds, insert the second previously programmed key into the ignition and turn it to the "ON" position for at least three seconds, but no longer than ten seconds. Then turn the key to the "OFF" position and remove it.
3. Within ten seconds, insert the new, unprogrammed key into the ignition and turn it to the "ON" position. Keep it in the "ON" position for at least six seconds. The security light on your dashboard should illuminate and then extinguish, indicating successful programming.
4. Turn the new key to the "OFF" position and remove it. Test the key fob functions (lock, unlock, panic) and ensure the vehicle starts with the new key.

Important Note: This procedure programs the integrated transponder chip that allows the car to start. The remote functions (lock/unlock) are usually programmed simultaneously. If the remote functions do not work, some vehicles may require a separate, simpler remote programming sequence (often involving cycling the ignition and pressing buttons), but for the 2015 Ford Explorer, the above procedure typically programs both simultaneously.

Battery replacement

The 2015 Ford Explorer key fob uses a single CR2032 coin cell battery. Replacing it is a straightforward process:

1. Locate the small release button or a slot on the side of the key fob. Press the button or insert a small flat-head screwdriver into the slot and gently twist to separate the two halves of the fob case.
2. Carefully remove the circuit board. The CR2032 battery will be visible in a holder on the circuit board.
3. Note the orientation of the old battery (usually positive side up). Gently pry out the old battery.
4. Insert the new CR2032 battery with the positive (+) side facing the same direction as the old one.
5. Align the two halves of the key fob case and snap them back together until they are securely closed.
6. Test all functions of your key fob to ensure it is working correctly.

Where to buy a replacement fob

• Ford Dealership:
  • Pros: Guaranteed genuine OEM part, often comes with programming service included. They handle all complexities.
  • Cons: Most expensive option. Expect to pay between $200-$350 for the fob and programming.
• Automotive Locksmith:
  • Pros: More affordable than a dealership, often provides mobile service. They have the necessary equipment to cut and program keys. They can often provide OEM or high-quality aftermarket fobs.
  • Cons: Prices can vary. Generally $150-$250 for parts and service.
• Online Retailers (e.g., Amazon, eBay):
  • Pros: Cheapest option for the fob itself. You can find OEM (new or used) and aftermarket options.
  • Cons: You still need to get the key blade cut and the fob programmed. The quality of aftermarket fobs can vary significantly. Be wary of counterfeit products. Aftermarket fobs typically cost $25-$75 online.

If on-board programming isn't supported

If you do not have two working "MyKey" keys for your 2015 Ford Explorer, or if the on-board programming procedure doesn't work, you will need professional assistance.

• Cost Expectations: For a dealership, expect the total cost for a new fob, cutting the key blade (if applicable), and programming to be in the range of $200-$350. A mobile automotive locksmith typically charges $150-$250 for the same services. The key difference is the specialized diagnostic equipment (scan tool) required to access the vehicle's computer and program the immobilizer transponder.
• Immobilizer Transponder: The 2015 Ford Explorer utilizes a Ford SecuriLock Passive Anti-Theft System (PATS) which incorporates a transponder chip within the key fob. This chip communicates with the vehicle's immobilizer system. If the correct transponder signal is not detected, the vehicle will not start, even if the key blade physically turns the ignition. Professional programming ensures this transponder is correctly synchronized with your vehicle's engine control unit (ECU).
