Disassembling a Volkswagen key fob can seem daunting, but with the right tools and a little patience, it’s a manageable task. This guide provides a step-by-step walkthrough on how to safely take apart your VW key fob, clean it, and reassemble it without damage. This process can be helpful for replacing a worn-out key fob battery, fixing a sticky button, or simply giving your key a thorough cleaning.
Disassembling the VW Key Fob
Before you begin, gather the necessary tools: a small flat-head screwdriver, a pair of small pliers or tweezers, and optionally, an air compressor for cleaning.
-
Remove the Key Components: Start by gently removing the silicone piece and the plastic cover from the back of the key fob. Then, take out the battery and the physical key blade. This will expose the internal components of the key fob.
-
Release the Chrome Housing: Locate the small pin holding the chrome housing together. Carefully push down on this pin with your small flat-head screwdriver. While applying pressure to the pin, gently twist the chrome housing. This should release the top chrome piece (the side with the key release button).
-
Separate the Housing: Once the top chrome piece is detached, you can push out the larger bottom chrome piece. The pin might stay in place; carefully remove it using your pliers or tweezers. Now, your key fob should be separated into four main parts: two chrome pieces, the silicone piece, and the plastic body.
-
Clean the Components (Optional): With the key fob disassembled, this is a good opportunity to clean the individual parts. Use an air compressor to blow away dust and debris. You can also use a soft cloth and a mild cleaning solution to wipe down the surfaces.
Reassembling the VW Key Fob
Putting your VW key fob back together is essentially the reverse of the disassembly process.
-
Reassemble the Plastic and Silicone: Place the silicone piece back onto the plastic body of the key fob, ensuring it sits flush and securely.
-
Attach the Chrome Housing: Add the larger bottom chrome piece to the assembly, making sure it aligns correctly with the silicone and plastic. Then, attach the smaller top chrome piece, ensuring a flush finish with the rest of the housing.
-
Reinsert the Pin: Carefully reinsert the small pin into its hole. This might require some pressure; using a small wooden block or similar object to support the key fob while pushing the pin in can be helpful. Make sure the pin is fully inserted and secure.
-
Replace the Key Blade and Battery: Slide the physical key blade back into its slot and insert the battery back into its compartment, ensuring the correct polarity.
-
Reattach the Covers: Finally, reattach the plastic back cover and the silicone piece, completing the reassembly process.
By following these steps, you can successfully disassemble, clean, and reassemble your VW key fob. Remember to be patient and gentle throughout the process to avoid damaging any of the delicate components. If you encounter any difficulties, consult a professional locksmith or your VW dealership for assistance.
