Is your 2003 Acura TL key fob malfunctioning, or did you get a replacement and need to program it? You’re in the right place! Programming your key fob for a 2003 Acura TL can be done easily at home without needing special tools. This guide will walk you through each step to get your key fob working in no time.
Before you begin, it’s important to understand a couple of things. When you enter programming mode on your Acura TL, it will erase all previously programmed key fobs. This means you’ll need to reprogram all your key fobs, not just the new one. Also, each step needs to be completed within 4 seconds of the previous one to prevent the system from exiting programming mode, and you should program all remotes within 10 seconds of each other.
Here’s how to program your 2003 Acura TL key fob:
-
Turn the Ignition ON: Insert your key into the ignition switch and turn it to the ON (II) position. This is the position right before you would start the engine.
-
Press Lock or Unlock: Within 4 seconds of turning the ignition ON, press either the LOCK or UNLOCK button on one of your key fobs. It doesn’t matter if the fob is currently programmed or not for this step.
-
Turn the Ignition OFF: Within 4 seconds of pressing the button, turn the ignition switch back to the LOCK (0) position. This is the position where you can remove your key.
-
Turn the Ignition ON Again: Again, within 4 seconds, turn the ignition switch back to the ON (II) position.
-
Repeat Steps 2-4 Two More Times: Repeat the sequence of pressing the LOCK or UNLOCK button (step 2), turning the ignition to LOCK (step 3), and then back to ON (step 4) two more times, using the same key fob you used in step 2.
-
Press Lock or Unlock Again (Confirmation): Within 4 seconds of the last ignition cycle, press the LOCK or UNLOCK button on the same key fob one more time. If you have successfully entered programming mode, the power door locks should cycle (lock and then unlock) automatically. This confirms you are now in programming mode and ready to program your remotes.
-
Program the First Remote: Within 10 seconds of the door locks cycling, press the LOCK or UNLOCK button on the key fob you are currently programming. The power door locks should cycle again to confirm that this remote has been successfully programmed.
-
Program Additional Remotes: If you have other key fobs to program, do so within 10 seconds of programming the first one. For each additional key fob, press the LOCK or UNLOCK button. The door locks should cycle each time to confirm successful programming of each remote.
-
Exit Programming Mode: Once you have programmed all desired key fobs, turn the ignition switch to the LOCK (0) position. This will exit programming mode.
-
Test Your Remotes: Test each of your programmed key fobs to ensure they are working correctly by pressing the LOCK and UNLOCK buttons and verifying the door locks respond as expected.

Troubleshooting Tips:
- Timing is Crucial: The 4-second and 10-second time limits are important. If you exceed these timeframes, you may exit programming mode and need to start over. Try to perform each step smoothly and quickly.
- Incorrect Key Fob: Ensure you are using the correct key fob for your 2003 Acura TL. The part number for the compatible key fob is G8D-444H-A. Using an incompatible fob will prevent successful programming.
- New Batteries: Make sure the key fobs you are trying to program have fresh batteries. Low battery power can sometimes interfere with the programming process.
- Repeat the Process: If you don’t get confirmation (door locks cycling) at any step, carefully go back to step 1 and repeat the entire process. Double-check that you are following each step exactly as described.
Programming your 2003 Acura TL key fob is a straightforward process. By following these instructions carefully, you can save time and money by programming your key fob yourself. If you continue to experience issues, consider consulting your Acura dealership or a professional automotive locksmith for assistance.
