Car keys for Honda

Losing a key fob for your Honda or needing to add an extra one can be a frustrating situation. But fear not! With some basic tools, a replacement key fob, and a bit of know-how, you can save money by making or adding a key fob yourself. This comprehensive guide will take you through the steps, offering solutions for various Honda models.

Assess Your Needs

Before you begin, determine whether you’ve lost your only key fob or need to add a spare. The process will vary depending on your situation.

  • Lost Key Fob: If you’ve lost all your key fobs, you’ll need to reprogram your Honda’s system to accept a new key.
  • Adding a Spare: If you have a working key fob and want to add another for convenience, you’ll primarily focus on programming the new key to work with your vehicle.

Gather Tools and Materials

Here’s what you’ll typically need:

  • Replacement Key Fob: Purchase a compatible replacement key fob for your Honda model. Ensure it matches your vehicle’s make, model, and year.
  • Small Flat-Head Screwdriver: This may be needed to open the key fob or access the internal components.
  • New Key Blade (if applicable): Some replacement key fobs come with a new key blade. If you need a physical key, ensure it’s included and can be cut to match your original key.
  • Access to Your Honda Vehicle: You’ll need to be near your Honda for programming and testing.

Steps to Make or Add a Key Fob

Step 1: Purchase a Replacement Key Fob

Find a compatible replacement key fob for your specific Honda model. You can purchase these online or from automotive stores. Make sure the replacement is designed for your vehicle’s year and model.

Step 2: Program the Key Fob

Programming methods can vary based on the Honda model and year. Here are some common approaches:

  • Manual Programming: Some Honda models allow for manual programming by following a sequence of actions using the ignition and door locks. Check your owner’s manual for specific instructions.
  • Using a Scanner Tool: Newer Honda models often require a scanner tool for programming. This tool connects to your car’s OBD-II port and communicates with the vehicle’s onboard computer system to sync the new key fob.

Refer to your Honda’s owner’s manual or reputable online sources for detailed programming instructions tailored to your specific model and year.

Step 3: Sync the Key Fob

If you’re adding a spare key fob, syncing it with your Honda’s system is essential. Here’s a general method:

  1. Sit in the Driver’s Seat: Ensure all doors are closed, and you’re seated inside the vehicle.
  2. Insert and Remove the Key: Insert your existing working key into the ignition and turn it to the “On” position (without starting the engine). Then, quickly remove the key.
  3. Press Lock/Unlock Buttons: Within five seconds of removing the key, press and hold the “Lock” or “Unlock” button on your existing key fob.
  4. Program the New Key Fob: While holding the button on your existing key fob, press the “Lock” or “Unlock” button on the new key fob. Hold for a few seconds until you hear the door locks cycle.
  5. Test the New Key Fob: After programming, test the new key fob to ensure all functions (lock, unlock, trunk release, panic button) work correctly.

Step 4: Cutting a New Key Blade (if needed)

If your replacement key fob includes a key blade and you require a physical key, you might need to have the key blade cut to match your original key. Visit a locksmith or automotive hardware store for this service.

Final Tips

  • Battery Replacement: If your new key fob has a battery compartment, ensure the battery is new or fully charged for optimal performance.
  • Backup Keys: Always keep spare keys in safe locations to avoid future issues.


By following these steps and guidelines, you can successfully make or add a key fob for your Honda vehicle without the need for expensive dealership services. Remember to research specific instructions for your Honda’s model and year, as programming methods can vary. With a bit of patience and attention to detail, you’ll have a functional key fob ready to use with your Honda. Happy DIY key fob programming!
