Programming Your 2003 Honda Odyssey EX Model Key Fob (Factory Installed System)
If your 2003 Honda Odyssey EX model came with a factory-installed keyless entry system, follow these steps. It’s important to note that this system can store up to three remotes. Programming a fourth remote will erase the memory of the first programmed remote.
-
Turn the Ignition ON: Insert your key into the ignition and turn it to the ON position (II). This is the position right before you would crank the engine to start.
-
Press Lock or Unlock: Within 4 seconds of turning the ignition ON, press the LOCK or UNLOCK button on your key fob. Ensure you point the remote towards the receiver, which is typically located near the glove box area.
-
Turn the Ignition OFF: Within 4 seconds of pressing the button, turn the ignition switch to the LOCK (0) position.
-
Repeat Steps 1-3 Two More Times: Repeat steps 1, 2, and 3 two more times using the same keyless remote from step 2. Essentially, you are cycling the ignition ON, pressing a button, and OFF, three times in total.
-
Turn the Ignition ON Again: Within 4 seconds of the last cycle, turn the ignition switch back to the ON (II) position.
-
Press Lock or Unlock and Confirm: Within 4 seconds, press the LOCK or UNLOCK button on the same remote once more. If you have successfully entered programming mode, the power door locks should cycle (lock and then unlock) automatically. Press the LOCK or UNLOCK button again.
-
Program Additional Remotes: If you have other remotes you wish to program, press the LOCK or UNLOCK button on each of them within 4 seconds of each other. After pressing a button on each remote, the door locks should cycle again to confirm that the system has accepted the remote’s signal.
-
Exit Programming Mode: Turn the ignition switch to the LOCK (0) position to exit the programming mode. The door locks should cycle one last time to confirm exit.
-
Test Your Remotes: Test each programmed remote to ensure they are working correctly by pressing the LOCK and UNLOCK buttons and verifying the doors respond.
Programming Your 2003 Honda Odyssey LX Model Key Fob (Dealer Installed System)

Repeat Steps 1-3 Two More Times: Repeat steps 1, 2, and 3 two additional times using the same key fob from step 2.
-
Turn the Ignition ON Again: Turn the ignition switch back to the ON (II) position.
-
Press Lock or Unlock and Confirm: Press the LOCK or UNLOCK button on the same remote. The power door locks should cycle to confirm you are in programming mode.

Program Additional Remotes: Press the LOCK or UNLOCK button on each additional remote you want to program. The door locks should cycle after each button press to confirm acceptance.
