How to Open a Volkswagen Car Key?
2 Answers
To open a Volkswagen car key, follow these steps: 1. Eject the mechanical key; 2. Insert a screwdriver into the gap of the mechanical key and twist to pry it open; 3. Rotate and pry open the side with the electronics to remove the circuit board. Taking the Volkswagen Sagitar as an example, it is a compact 4-door, 5-seater sedan with body dimensions of: length 4753mm, width 1800mm, height 1462mm, and a wheelbase of 2731mm. The Volkswagen Sagitar is equipped with a 1.2T turbocharged engine and a 5-speed manual transmission, delivering a maximum power of 85 kW and a maximum torque of 135 Nm. It features front-wheel drive, with a front suspension using MacPherson independent suspension and a rear suspension using multi-link independent suspension.
I frequently disassemble Volkswagen keys, especially when fixing button issues. First, remove the mechanical key blade. There's usually a small button on the side of the key body—press it and gently pull out the key blade. Next, locate the housing clips. Volkswagen keys typically feature a plastic clip design without screw holes, so you can gently pry them open from the seams using a plastic pry tool or a nail file. Avoid metal tools to prevent scratching or short-circuiting the internal circuitry. Once the key splits into two halves, be careful not to yank any wires or damage the chipboard. If you're replacing the battery, the common CR2032 battery can be found in supermarkets—make sure to install the new battery with the correct polarity. When reassembling, align the cover and press firmly until you hear a click, indicating it's properly seated. Take your time during the process—slow and steady wins the race. If it feels too tight, the clips might not be aligned correctly. After disassembly, cleaning the button contacts can extend their lifespan. If it's your first attempt, I recommend working in a well-lit area to minimize the risk of mistakes.
