How to Open a Volkswagen Car Remote Key?
3 Answers
Volkswagen car remote key can be opened by following these steps: 1. Unfold the key at the folding point to pop out the mechanical key; 2. Insert a flat-head screwdriver into the small horizontal groove in the recess, press firmly, and turn the screwdriver; 3. Pry open a larger gap, hold the key ring, pull hard, and forcefully separate the side to expose the battery and circuit board section. Remove the old battery and replace it with a new one. Volkswagen is a German automobile manufacturer headquartered in Wolfsburg, Germany, with brands such as Audi and Volkswagen under its umbrella. Taking the Phaeton as an example, it is positioned as a large premium luxury sedan. In terms of body dimensions, the Phaeton measures 5175mm in length, 1903mm in width, and 1450mm in height, with a wheelbase of 3001mm.
I've taken apart Volkswagen keys several times, and it feels quite simple—the key is finding the right spot. Many Volkswagen keys have a small button in the middle; you need to press it and then gently pry open the shell using a small screwdriver or your fingernail to slowly work it open from the gap. Just don’t use too much force, as those plastic clips can break easily, and if they do, you’ll have to replace the entire key cover. Once opened, you’ll see the battery compartment, usually a CR2032 model—just swap in a new one. When reassembling, align it properly until you hear a click to ensure it’s securely fastened. I’d recommend checking the manual or following a tutorial on YouTube first, since the key circuitry is quite delicate, and damaging it could cost hundreds to fix. It’s also a good idea to keep a spare button battery at home, as the signal weakens when the key’s battery runs low.
As someone who frequently does minor repairs myself, I don't think disassembling a Volkswagen key needs to be overly complicated. Take my old Tiguan key for example—it has an arrow mark on the back, and prying it open from there does the trick. I used a stiff card to gently slide in and make a full circle, which separated the casing. Just be careful not to touch the circuit board, as the battery compartment is directly exposed. However, it's worth noting that Volkswagen keys are designed quite tightly, so the first attempt might be tricky. You might want to practice a few times or ask for help. The main reason for disassembly is usually to replace the battery, but remember that the dashboard will show a warning light before the battery dies, signaling it's time to act. I've had to disassemble a key to dry it out after it got wet, so it's best to protect your key from water exposure. If you really can't manage to open it, spending a bit at a repair shop to have a technician handle it is the safer option.
