Lost your key fob or need to program a new one for your 2004 Acura MDX?

This guide provides clear, easy-to-follow instructions to get your 2004 Acura MDX key fob programmed quickly and efficiently.
Step-by-Step Programming Guide for Your 2004 Acura MDX Key Fob
Before you begin, gather all the key fobs you intend to program. It’s important to note that this procedure will erase all previously programmed remotes. Therefore, you must program all existing and new remotes you plan to use with your vehicle during this session. Ensure you have all remotes ready before starting the programming sequence.
Timing is crucial in this process. You must complete each step within 5 seconds. If you exceed this time limit at any point, you’ll need to start the entire process from the beginning. However, you can attempt these steps as many times as needed to successfully program your key fob.
Here are the steps to program your 2004 Acura MDX key fob:
-
Enter your Acura MDX and close all doors. Make sure all doors, including the trunk or liftgate, are completely closed.
-
Repeat the following sequence THREE times using the same key fob for each repetition:
A. Turn the ignition to the ON position (II). This is the position just before you would start the engine. The dashboard lights should be illuminated.
B. Press the LOCK button on the key fob you are programming.
C. Turn the ignition to the OFF position (I). This is the position where the engine is off, but the key is still in the ignition.
Repeat steps A, B, and C a total of THREE times.
-
Turn the ignition to the ON position (II) one last time. Leave the ignition in the ON position after the third repetition of the previous sequence.
-
Using the same key fob from step 2, press the LOCK button again. At this point, you should hear the door locks cycle (lock and unlock). This confirms that your 2004 Acura MDX has successfully entered programming mode.
-
Within 10 seconds of the door locks cycling, press the LOCK button on the same key fob once more. The door locks will cycle again to confirm that this key fob has been programmed.
-
If you have additional key fobs to program, repeat step 5 for each additional remote. You have a 10-second window to program each additional remote. Each time you successfully program a remote, the door locks will cycle to confirm.
-
Turn the ignition to the OFF position (I). This will exit the programming mode.
-
Test all programmed key fobs to ensure they are working correctly by locking and unlocking the doors and, if applicable, testing other remote functions.
By following these steps carefully, you should be able to successfully program your 2004 Acura MDX key fob. If you encounter difficulties or prefer professional assistance, you can search for a qualified key fob installer in your area using online directories.
