Is your VW key fob looking a bit worse for wear? Perhaps the casing is cracked, or you simply want to give it a thorough clean. Taking apart your VW key fob might seem daunting, but with the right approach and a little care, it’s a surprisingly straightforward DIY task. This guide, based on personal experience, will walk you through the process of safely disassembling your VW key fob.
Before you begin, it’s important to note that this guide is for informational purposes and based on a personal experience of disassembling a specific VW key fob model. While the general principles may apply to other models, always proceed with caution and at your own risk. If you’re uncomfortable with DIY electronics repair, it’s always best to consult a professional.
Tools You’ll Need
Before you start taking your VW key fob apart, gather these simple tools:
- Small screwdriver: A precision screwdriver set will be ideal, as you’ll need a very small head to push a pin and potentially a slightly larger one for prying gently.
- Small pliers or tweezers: These can be helpful for removing small components like the pin.
- Air gun or compressed air (optional): For cleaning the components once disassembled.
- Soft cloth: To protect the key fob surfaces and for cleaning.
Step-by-Step VW Key Fob Disassembly Guide
Let’s get started with disassembling your VW key fob. Follow these steps carefully:
Step 1: Remove the Silicone Piece and Plastic Cover
The first step is to remove any easily detachable external parts. In many VW key fobs, you’ll find a loose silicone piece or button cover and a separate plastic cover on the back. Gently peel off the silicone piece if present. Then, carefully pry off the plastic cover on the back of the key fob. You might be able to do this with your fingernail or the edge of a plastic opening tool to avoid scratching the plastic.

Step 2: Remove the Battery and Physical Key
Next, remove the battery and the physical emergency key from the fob. The battery compartment is usually revealed once you remove the back plastic cover. Take out the battery, noting its orientation for reassembly later. Then, slide out the physical key blade. This is usually released by a small button or lever on the side of the key fob. Set these components aside in a safe place.

Step 3: Locate and Push the Retaining Pin
With the external parts and battery removed, you’ll now need to locate a small retaining pin that holds the key fob housing together. This pin is usually located on the side of the key fob, often near where the key blade is released. Using your small screwdriver, carefully push down on this pin. You may need to apply a bit of pressure.
Step 4: Twist and Release the Chrome Top Piece
While pushing down on the pin, gently twist the key fob housing. This twisting motion, combined with pushing the pin, should release the top chrome piece of the housing. This is typically the chrome part located on the side where the key release button is situated. Once released, you should be able to carefully separate this top chrome piece.

Step 5: Remove the Larger Chrome Piece
With the top chrome piece removed, you should now be able to push out the larger remaining chrome piece from the housing. It should slide out relatively easily once the top piece is detached. If the pin stayed in place during the previous steps, you can now carefully pull it out using small pliers or tweezers.

Step 6: Clean the Components
Now that your VW key fob is disassembled, you can take the opportunity to clean all the components. Use a soft cloth to wipe away any dirt or grime. If you have compressed air or an air gun, you can use it to blow out any dust or debris from the internal parts and crevices.
VW Key Fob Reassembly Guide
Reassembling your VW key fob is essentially the reverse of the disassembly process. Follow these steps to put it back together:
Step 1: Place the Silicone Piece
Start by placing the silicone button piece back onto the plastic part of the key. Ensure it sits correctly in its designated position.
Step 2: Add the Larger Chrome Piece
Next, carefully add the larger chrome piece of the housing. Make sure it aligns properly with the silicone piece and the plastic key body, creating a flush finish.
Step 3: Add the Top Chrome Piece and Pin
Now, add the top chrome piece. Align it with the other components and push it into place. Once aligned, reinsert the small retaining pin. This might require a bit of force. You can use a small wooden plank or a hard, flat surface to gently press the pin back in until it is securely in place and flush with the surface of the chrome housing.
Step 4: Reinsert the Physical Key and Battery
Finally, slide the physical key blade back into its slot until it clicks into place. Then, reinsert the battery, ensuring you place it in the correct orientation as you noted during disassembly. Replace the back plastic cover and the silicone button piece if they were originally present.
Conclusion
Congratulations! You have successfully taken apart and reassembled your VW key fob. This process is indeed reasonably easy, as demonstrated by this guide. By following these steps, you can clean your key fob, and potentially address minor issues like replacing the battery or cleaning internal contacts. While this guide provides a general overview, remember that key fob designs can vary slightly. If you encounter any difficulties or are unsure about any step, it’s always wise to seek professional help. Perhaps a video guide would be even more helpful for visual learners – something to consider for the future!
