Is your 2004 Honda key fob acting up? Often, the culprit is a dead battery. Replacing the battery in your 2004 Honda key fob is a straightforward process, and sometimes, after a battery change, you might find you need to reprogram your remote to regain full functionality. This guide will walk you through both changing your key fob battery and, if necessary, reprogramming your 2004 Honda key fob. Keep all your remotes handy as you’ll need to program them all in the same session. Ensure all doors and the rear hatch/trunk are firmly closed before you begin. You’ll only need one remote to start the programming sequence, but all remotes must be programmed together. Remember, each step must be completed within 5 seconds for successful programming.
Here’s how to reprogram your 2004 Honda key fob:
-
Get Inside and Close Up: Sit in the driver’s seat of your 2004 Honda with all doors and the trunk completely shut.
-
Ignition ON & Lock Press: Insert your key into the ignition. Turn the key to the “ON” position (position “II” on the ignition bezel) until the dashboard lights illuminate. Within 5 seconds of turning the key to ON, press the “Lock” button on your remote for about one second, then release.
-
Ignition OFF: Turn the ignition key to the “OFF” position (position “I” on the ignition bezel). The dash lights should turn off.
-
Repeat the Cycle: Repeat steps 2 and 3 three more times. This means you will have completed the sequence a total of four times. Ensure each step is done within 5 seconds of the previous one.
-
Enter Programming Mode: On the fourth turn of the key to the “ON” position, press the “Lock” button on one of your remotes. You should hear the door locks cycle, making a “clunk” sound. Note that the doors will not actually lock or unlock at this stage, this sound simply indicates that the system has entered programming mode. Do not turn the key off after this step.
-
Program Each Remote: Within 5 seconds of hearing the locks cycle and within 5 seconds of each other, take each remote you wish to program and press the “Lock” button for about one second, then release. Do this for every remote. Each time you press a remote button, the door locks should cycle again. You can program up to three remotes in total. This entire step needs to be completed within 10 seconds.
-
Finalize Programming: Turn the ignition key completely to the “OFF” position and remove the key from the ignition. Open the car door and step out, then close the door.
Your 2004 Honda key fobs should now be programmed and fully functional. Test each remote to ensure they are working correctly. If your remote has a trunk/hatch release button, remember that you usually need to press and hold this button for a few seconds for the trunk/hatch to open.
If you encounter issues, double check each step and timing, and try the process again. Sometimes, persistence is key! Many users have found success with this method for their 2004 Honda vehicles.
