2018 Honda CR-V Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2018 Honda CR-V does not support DIY on-board programming for its key fobs. The vehicle's computer system requires a specialized scan tool to program new key fobs. This process involves syncing the new fob's unique code with the car's immobilizer system, a task that can only be performed by a qualified automotive locksmith or Honda dealership.

Attempting to program a new key fob without the proper equipment can lead to issues with your vehicle's security system and could even prevent your car from starting.

Battery replacement

Replacing the battery in your 2018 Honda CR-V key fob is a straightforward process:

1. Locate the small release button or switch on the side of the key fob. Press or slide it to release the emergency key blade. Pull the emergency key blade out of the fob.
2. With the emergency key removed, you'll see a small slot or indentation along the edge of the key fob. Use a small flat-head screwdriver or a coin to carefully pry the two halves of the fob apart.
3. Once opened, you'll see the circuit board and the CR2032 battery. Note the orientation of the old battery (which side is facing up).
4. Gently remove the old battery and insert the new CR2032 battery, ensuring the positive (+) side is facing the same direction as the old battery.
5. Align the two halves of the key fob and press them firmly together until they click securely into place.
6. Reinsert the emergency key blade into the fob until it locks.

Test your key fob to ensure it locks and unlocks your vehicle.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2018 Honda CR-V, you have a few main options, each with pros and cons:

• Honda Dealership:

  • Pros: Guaranteed genuine OEM part, programmed on-site with specialized tools, comprehensive warranty.
  • Cons: Most expensive option. Expect to pay between $200-$350 for the fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than a dealership, can provide both OEM and quality aftermarket fobs, equipped with the necessary programming tools, convenient mobile services available.
  • Cons: Prices can vary, ensure the locksmith specializes in automotive keys and programming. Expect to pay between $150-$280 for the fob and programming.

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

  • Pros: Potentially the cheapest option for the fob itself. Wide selection of aftermarket fobs.
  • Cons: You'll still need to pay a locksmith or dealer for programming. Risk of purchasing a non-compatible or low-quality fob. Always verify the FCC ID (ACJ876E0G) and part number (72147-TLA-A01) before purchasing. Cost for the fob alone could be $30-$100, plus programming fees.

If on-board programming isn't supported

As mentioned, the 2018 Honda CR-V requires a scan tool for key fob programming. This means you'll need to factor in the cost of professional programming, whether from a Honda dealership or a qualified automotive locksmith.

Your 2018 Honda CR-V key fob also contains an immobilizer transponder (typically an ID47 chip). This transponder is crucial for starting your vehicle. Even if your fob can lock and unlock the doors, the car will not start if the transponder isn't correctly programmed to the vehicle's immobilizer system. This is another reason why specialized tools are required for programming.

Cost Expectations:

• Dealership: Total cost including fob, cutting, and programming generally ranges from $200 to $350.
• Automotive Locksmith: Total cost including fob, cutting, and programming generally ranges from $150 to $280.

The cost for cutting the emergency key blade is usually included in the overall service when you purchase the fob and programming from a professional.
