Lost your key fob or need to program a new one for your 2012 Volkswagen Passat? Don’t worry, programming your key fob can be a straightforward process you can often do yourself. This guide will walk you through the steps to program your 2012 Volkswagen Passat Key Fob, saving you time and potentially money.
Programming Your 2012 Volkswagen Passat Key Fob
Before you begin, ensure you have all the necessary keys. You will need one already programmed key to start the ignition and the new key fob you wish to program. Follow these steps carefully:
-
Ignition ON: Insert your already programmed key into the ignition switch and turn the ignition to the “ON” position. Do not start the engine. Leave the key in the ignition throughout the programming process.
-
Mechanical Lock: Exit the vehicle and manually lock the driver’s side door using your second, mechanical key. It’s crucial to physically lock the door with the key in the lock cylinder.
-
Press “Open” Button: Take the key fob you are programming. Press the “Open” or “Unlock” button on the fob once. Immediately after pressing the button, you should hear a short horn signal. This confirms the vehicle has recognized the signal from the key fob.
Note: If you are programming multiple key fobs, you will need to repeat step 3 with a slight variation. For the second key fob, press the “Open” button twice (with a one-second interval between presses). For the third, press it three times, and for the fourth, four times. For example, to program the second key fob, press “Open”, wait one second, then press “Open” again.
-
Activate Coding: After pressing the “Open” button the required number of times, wait for approximately 6 seconds. Then, press the “Open” button one more time to finalize and activate the coding process.
-
Confirmation and Testing: The remote unit should now be programmed to your 2012 Volkswagen Passat. You can now switch the ignition off and remove the key from the ignition.
-
Unlock with Remote: Test the newly programmed key fob by pressing the “Unlock” button. The central locking system should respond, and your doors should unlock.

Erasing Key Fob Memory (Optional)
If you have lost a key fob or want to ensure old fobs no longer operate your vehicle, you can erase the memory. This process will clear all previously programmed key fobs, and you will need to reprogram any fobs you wish to use afterward.
-
Ignition ON: As with programming, insert a working key into the ignition and turn it to the “ON” position (do not start the engine). Leave the key in the ignition.
-
Mechanical Lock: Manually lock the driver’s side door from the outside using your second mechanical key.
-
Press “Open” Button Five Times: On the key fob you are using for the erasing process (it can be any of the old fobs), press the “Open” button five times in one-second intervals. You should hear a short horn signal.
-
Activate Memory Erasing: After approximately 6 seconds from the horn signal, press the “Open” button one more time to activate the memory erasing process.
-
Memory Erased: The memory is now erased. None of the previously programmed key fobs will operate the central locking system. Switch the ignition off and remove the key.
After erasing the memory, you can program up to four new key fobs using the programming procedure outlined above.
This guide should help you program your 2012 Volkswagen Passat key fob or erase the memory effectively. Always double-check your vehicle’s manual for the most accurate and model-specific instructions. If you encounter any issues, consulting a professional locksmith or Volkswagen dealership is recommended.
