Lost your key fob or need to program a new one for your 2004 Acura TSX? Programming your key fob yourself can save you time and money compared to dealership services. This guide provides simple, step-by-step instructions to program your 2004 Acura TSX key fob quickly and efficiently at home. Make sure to follow each step carefully to ensure successful programming.
Programming Steps
Before you begin, note that entering programming mode will erase all previously programmed key fobs. You will need to reprogram all your remotes during this process. Ensure you have all key fobs you wish to program ready before starting. Each step must be completed within 4 seconds of the previous one, and you must program remotes within 10 seconds of each other once in programming mode.
-
Turn Ignition to ON (II): Insert your key into the ignition switch and turn it to the “ON” position (II). This is the position right before you would start the engine.
-
Press Lock or Unlock Button: Within 4 seconds of turning the ignition ON, press the “LOCK” or “UNLOCK” button on one of your key fobs. It doesn’t matter if this fob is already programmed or brand new.
-
Turn Ignition to LOCK (0): 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 the key.
-
Turn Ignition to ON (II) Again: Within 4 seconds of turning the ignition to LOCK, quickly turn it back to the “ON” (II) position.
-
Repeat Steps 2-4 Twice More: Repeat steps 2, 3, and 4 two more times, using the same key fob button you used in step 2. You will have cycled the ignition ON and pressed the remote button a total of three times.
-
Press Lock or Unlock Button (Confirmation): Within 4 seconds of the last ignition cycle, press the “LOCK” or “UNLOCK” button on the same key fob used in step 2 again. If you have successfully entered programming mode, the power door locks should cycle (lock then unlock) automatically. This confirms you are now in programming mode. If the door locks do not cycle, you will need to repeat steps 1-6 more quickly.
-
Program 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 door locks should cycle again to confirm that this remote has been successfully programmed.
-
Program Additional Remotes: If you have more key fobs to program, within 10 seconds of the last successful programming confirmation, press the “LOCK” or “UNLOCK” button on the next key fob. Again, the door locks should cycle to confirm programming. Repeat this step for all remaining key fobs you wish to program.
-
Exit Programming Mode: Turn the ignition switch to the “LOCK” (0) position to exit programming mode.
-
Test Remotes: Test all programmed key fobs to ensure they are working correctly by pressing the “LOCK” and “UNLOCK” buttons and verifying the door locks respond.
By following these instructions, you should be able to program your 2004 Acura TSX key fobs easily.
