2003 Honda Accord EX Key Fob Programming Instructions
Before you begin, note that entering programming mode will erase all previously programmed remotes. You will need to reprogram all your key fobs during this process. Make sure to complete each step within 5 seconds of the last to prevent the system from exiting programming mode prematurely.
Here’s how to program your 2003 Honda Accord EX key fob:
-
Turn the ignition to the ON position (II). This is the position right before you would start the engine.
-
Press the LOCK or UNLOCK button on one of your key fobs. It doesn’t matter if the remote is already programmed or not for this step.
-
Turn the ignition to the LOCK position (0). This is the position where you can remove your key.
-
Repeat steps 1, 2, and 3 two more times using the same key fob remote you used in step 2. So, in total, you will have cycled the ignition ON-Press Button-LOCK three times.
-
Turn the ignition switch to the ON position (II) again.
-
Press the LOCK or UNLOCK button on the same key fob used in step 2. If you have successfully entered programming mode, the power door locks should cycle (lock and then unlock) automatically to confirm.
-
For each key fob you wish to program, press the LOCK or UNLOCK button. After pressing a button on each remote, the door locks should cycle again to confirm that the system has accepted the remote’s signal.
-
Turn the ignition switch to the LOCK position (0) to exit programming mode.
-
Test all your programmed key fobs to ensure they are working correctly.
By following these steps, you should be able to successfully program your 2003 Honda Accord EX key fob. If you are still experiencing issues or need to purchase a replacement key fob, visit Keylessentryremotefob.com for a wide selection of key fobs and expert support.
