Is your 2003 Toyota Camry key fob suddenly not working? Before you rush to a dealership or locksmith, you might be able to fix it yourself. This guide will walk you through a simple DIY method to reprogram your key fob and potentially save you time and money.
Here’s how to attempt to reprogram your 2003 Toyota Camry key fob yourself:
-
Get Ready: Ensure your 2003 Camry is in the correct starting state. This means your driver’s side door is open, all other doors and the trunk are securely closed, and importantly, the driver’s door is unlocked. Have your new key fob ready.
-
Key Insertion Sequence (Within 5 Seconds): Quickly insert your key into the ignition cylinder, and immediately pull it out. Repeat this insert and remove action one more time, all within a 5-second window. Do not turn the ignition at any point during this process.
-
Door Cycling Sequence (Within 40 Seconds): Now, you need to cycle the driver’s side door. Close the driver’s door, then open it. Repeat this close and open cycle one more time.
-
Final Key and Door Sequence (Within 40 Seconds): Insert the key into the ignition (again, do not turn it), and then pull it out. Next, cycle the driver’s door closed and open two more times, just as you did in the previous step. After the second door cycle, insert the key into the ignition and leave it there. Close the driver’s door.
-
Ignition Timing is Crucial: With the key in the ignition and the driver’s door closed, turn the ignition to the “ON” position (just before starting the engine), and then immediately turn it back to the “OFF” position. Remove the key completely from the ignition.
-
Programming Mode Confirmation: If you’ve correctly followed the sequence, within 3 seconds, you should hear the power door locks cycle – they will lock and then unlock automatically. This lock cycle indicates that your 2003 Toyota Camry has successfully entered programming mode. If you don’t get this confirmation, return to step 1 and carefully repeat the process.
-
Key Fob Programming (Within 40 Seconds): Now for the programming itself. On your key fob, press and hold both the “lock” and “unlock” buttons simultaneously for about 1.5 seconds. Immediately after releasing both buttons, press and hold only the “lock” button for 2 seconds. Within 3 seconds, the door locks should cycle once (lock then unlock), confirming successful programming of that key fob. If the door locks cycle twice, it means the remote was not accepted, and you should repeat steps 6A and 6B.

-
Programming Additional Key Fobs: If you have more key fobs to program, repeat step 7 for each additional remote.
-
Exit Programming Mode: Open the driver’s door to finalize the programming process and exit programming mode.
By following these steps carefully, you can attempt to reprogram your 2003 Toyota Camry key fob yourself. Remember, timing and accuracy are key to successful programming. If you encounter issues or the key fob still doesn’t work after these steps, it might be time to consult a professional locksmith or your local Toyota dealership for further assistance.
