Is your 2004 Honda Key Fob not working? Don’t panic! Before you rush to the dealership, there are a few simple steps you can take to diagnose and potentially fix the issue yourself. This guide will walk you through troubleshooting common problems with your 2004 Honda key fob, from battery replacement to reprogramming and even sourcing a new fob if needed.
First things first, let’s check the most common culprit: the battery. It’s surprisingly easy to install a new key fob battery incorrectly, so double-check the polarity (+/- vs. -/+) to ensure it’s properly aligned. If you’re unsure about the battery’s condition, testing it with a multimeter is a good idea. Batteries, especially those from online marketplaces, can sometimes be old stock and have a reduced lifespan. If you recently replaced the battery and your 2004 Honda key fob still isn’t working, consider the possibility of a faulty or expired battery.
If the battery is not the issue, or if you’re looking to replace a lost or damaged fob, purchasing a new key fob for your 2004 Honda is more affordable than you might think. Online marketplaces like AliExpress and eBay offer a variety of options. You can find replacement fobs specifically designed for 2004 Honda models such as the Civic and Pilot at competitive prices. Look for fobs with FCC ID NHVWB1U523 or NHVWB1U521 to ensure compatibility with your vehicle’s keyless entry system.

Consider upgrading to a flip key for added convenience and to avoid the discomfort of a traditional key fob in your pocket. Once you have a new or replacement 2004 Honda key fob, you’ll likely need to reprogram it to work with your car. Fortunately, you can easily do this yourself without a trip to the mechanic.
Follow these steps to reprogram your 2004 Honda key fob:
- Ensure all doors and the rear hatch/trunk are closed. Have all your remotes for the vehicle ready.
- Sit inside your 2004 Honda with all doors tightly shut.
- Insert your key into the ignition and turn it to the “ON” position (position “II”) so the dashboard lights illuminate. Within 5 seconds, press the “Lock” button on one of your remotes for about a second and release.
- Turn the key to the “OFF” position (position “I”) – the dashboard lights will turn off.
- Repeat steps 3 and 4 three more times (a total of four cycles). Each step must be completed within 5 seconds of the previous one.
- On the fourth turn of the key to the “ON” position, press the lock button on one of the remotes. You should hear the door locks cycle (a clunking sound). This indicates the system has entered programming mode. Do not turn the key off at this point.
- Within 5 seconds of entering programming mode, and within 5 seconds of each other, press the lock button on each remote you wish to program for about a second and release. Each time you press a remote button, the locks should cycle. You can program up to three remotes in this session.
- Turn the ignition completely off and remove the key. Exit your 2004 Honda and close the door.
Your 2004 Honda key fob should now be programmed and functioning correctly. Test all buttons, including the trunk/hatch release (which may require holding the button for a few seconds).
If you encounter difficulties or prefer professional assistance, you can always contact your local Honda dealership. However, be prepared for a potentially higher cost for their services. By following these steps, you can likely resolve your 2004 Honda key fob issues yourself, saving time and money that could be better spent – perhaps on a nice dinner out!
