Lost your key fob or need to program a new one for your 2005 Acura MDX? No need to rush to the dealership and spend a fortune. Programming your 2005 Acura MDX key fob is a straightforward process you can easily do yourself at home. This guide provides simple, step-by-step instructions to get your key fob programmed and working in minutes.
Before you begin, make sure you have all the key fobs you intend to program with you. This procedure will erase all previously programmed remotes, so you’ll need to reprogram all of them, both old and new, in one session.
Step-by-Step Programming Instructions
-
Get Inside and Close the Doors: Enter your 2005 Acura MDX and ensure all doors are completely closed. This is crucial for the programming sequence to work correctly.
-
Ignition Cycling (Repeat 3 Times): This step involves a quick sequence of ignition and remote button presses. You must complete each sub-step within 5 seconds. Use the same remote for this entire step.
- A. Turn Ignition ON (Position II): Insert your key into the ignition and turn it to the “ON” position (II) – this is the position right before starting the engine, where the dashboard lights up.
- B. Press the LOCK Button: Immediately press the “LOCK” button on your key fob remote.
- C. Turn Ignition OFF (Position I): Turn the ignition back to the “OFF” position (I).
Repeat steps A, B, and C a total of THREE times.
-
Ignition ON Again: Turn the ignition switch to the “ON” position (II) one last time.
-
Lock Button Confirmation: Press the “LOCK” button on the same remote you used in step 2. If you have successfully entered programming mode, you will see the door locks cycle (lock and unlock). This confirms the system is ready to program your remote.
-
Program the Remote: Press the “LOCK” button on the same remote again. The door locks will cycle once more, indicating that this remote has been successfully programmed.
Programming Additional Remotes: If you have extra key fobs to program, repeat step 7 for each additional remote. You have a 10-second window to program each subsequent remote. Each successful programming will be confirmed by the door locks cycling.
-
Exit Programming Mode: Turn the ignition switch to the “OFF” position (I). This will exit the programming mode.
Now, test all your programmed key fobs to ensure they are working correctly. You should be able to lock and unlock your 2005 Acura MDX, as well as activate other remote functions if your key fob is equipped with them.
If you encounter any difficulties during this programming process, double-check each step and ensure you are completing them within the 5-second time limit.
