Losing a car key or needing a spare is a common hassle for car owners. If you drive a Honda Fit and are looking for a backup key, you might be wondering about the costs involved. Dealerships often quote significant labor charges for key programming, leading many to search for a more affordable solution. The question arises: can you program a Honda Fit car key yourself? This guide explores whether programming your own Honda Fit key is possible and provides a step-by-step method based on readily available information.
Understanding Honda Fit Key Programming
Modern car keys, especially those with keyless entry, are not just simple pieces of metal. They contain transponder chips that communicate with your car’s immobilizer system. This system is a security feature designed to prevent theft. When you start your car, the immobilizer verifies the key’s signal. For a new key to work with your Honda Fit, it needs to be programmed to your car’s system.
Dealerships have specialized tools and diagnostic equipment to perform this programming. However, for certain Honda models and keys, a DIY programming method might be available, potentially saving you a significant amount of money on labor costs.
DIY Programming Sequence for Honda Fit Keys
Based on information found in online forums and discussions, a specific sequence of actions might allow you to program a new remote key fob for your Honda Fit. It is important to note that this method may not work for all models and years, and success can vary. However, it’s a potentially cost-effective approach to try before resorting to professional services.
Before you begin:
- Ensure you have a new, compatible OEM Honda Fit key.
- Make sure all doors, hood, and hatch are closed properly.
- Be prepared to follow the timing precisely in each step.
Programming Steps:
- Turn the ignition switch to the ON position (II). This is the position just before you start the engine, where the dashboard lights are illuminated.
- Within 1 to 4 seconds, press the lock button on your new transmitter key fob.
- Within 1 to 4 seconds, turn the ignition switch to the OFF position.
- Within 1 to 4 seconds, turn the ignition switch back to the ON position (II).
- Within 1 to 4 seconds, press the lock button on your transmitter key fob again.
- Within 1 to 4 seconds, turn the ignition switch to the OFF position.
- Within 1 to 4 seconds, turn the ignition switch back to the ON position (II).
- Within 1 to 4 seconds, press the lock button on your transmitter key fob once more.
- Within 1 to 4 seconds, turn the ignition switch to the OFF position.
- Within 1 to 4 seconds, turn the ignition switch back to the ON position (II) for the fourth time.
- Within 1 to 4 seconds, press the lock button on your transmitter key fob.
- Listen for the sound of the door lock actuators. You should hear the doors lock and unlock, confirming programming mode. Immediately press the lock button again to store the code. If you don’t press it again, the code may not be saved.
- If you have additional key fobs to program, within 10 seconds, press the lock button on each of them. Listen for the door lock actuators after pressing each fob’s button to confirm successful programming.
- Turn the ignition switch to the OFF position and remove the key.
- Test all programmed keys to ensure they properly lock/unlock the doors and start the ignition.
Immobilizer Chip Considerations
While this sequence aims to program the remote key fob functions (locking/unlocking), it’s crucial to understand if it also programs the immobilizer chip. The immobilizer chip is what allows the car to start. It’s possible that this DIY method only programs the remote functions and not the immobilizer.
If the above sequence only programs the remote but not the immobilizer, you might be able to unlock and lock your doors with the new key, but the car may not start. In some cases, the immobilizer programming might require specialized equipment that is only available to dealerships or certified locksmiths.
Alternatives and When to Seek Professional Help
If the DIY programming method does not work for your Honda Fit, or if you are uncomfortable attempting it, professional help is readily available.
- Dealership: Honda dealerships are fully equipped to program keys for your Honda Fit. While they may be more expensive, they guarantee the key will be programmed correctly and work with your car.
- Certified Locksmiths: Many automotive locksmiths have the necessary tools and expertise to program car keys, often at a lower cost than dealerships. Ensure they are certified and experienced with Honda vehicles.
Conclusion
Programming your own Honda Fit car key can potentially save you money, and the DIY method described above is worth trying. However, be aware of its limitations, especially regarding the immobilizer chip. If you encounter difficulties or prefer a guaranteed solution, seeking professional help from a dealership or a certified locksmith is recommended. Always prioritize the security and proper functioning of your vehicle’s key system.
