Method for replacing the battery in the new Magotan's key: 1. Take out the spare mechanical key, then remove the silver decoration below the key; 2. Use your thumb to push firmly towards the hidden key side to remove the silver decorative cover; 3. Open the rear cover of the key and pry off the back cover; 4. Remove the old battery and replace it with a new one, then reassemble following the original steps. The Magotan is the first B-segment sedan produced and sold by FAW-Volkswagen since its establishment. In terms of body dimensions, it measures 4866mm in length, 1832mm in width, and 1464mm in height, with a wheelbase of 2812mm.
I've been driving the new Magotan for a while and have changed the key battery quite a few times. It's actually quite simple. There's usually a thin seam on the back of the key. Just use a small flat-head screwdriver or a coin to gently pry it open along the seam. Inside, you'll find a small round battery, which is the CR2032 model. Gently take it out and put in the new battery, making sure the marked side faces up. After installation, just snap the cover back on until you hear a click, and it's secure. If the battery is running low, you'll notice the unlocking distance becomes shorter or the buttons respond sluggishly—that's when it's time for a replacement. I recommend buying branded button batteries like Panasonic or Energizer; they're of better quality and last longer. During routine maintenance, it's a good idea to check the battery compartment contacts for any rust to prevent poor contact. The whole process takes no more than three minutes, and you can do it yourself without spending extra at the 4S shop.
Changing the battery for my new Magotan key was super easy, even a beginner can handle it. Just prepare a CR2032 battery and a thin card like a bank card. Aim for the gap at the edge of the key's back, insert the card, and gently pry open the cover. You'll see a small round battery—pop it out and replace it with the new one, usually with the positive side facing outward. Then snap the cover back on and test the remote functions; if everything works, you're good to go. When the battery is running low, the remote often malfunctions or the light dims, so I keep a spare in the glove box. There are plenty of video tutorials online—just search and watch for two minutes to learn, saving both money and hassle. Don't pry too hard to avoid scratching the key; it's a piece of cake and not as complicated as you might think.
I believe the key to replacing the battery in the new Magotan's key lies in the details. Avoid using sharp tools and opt for a plastic pry bar for safety. Ensure the battery is the CR2032 model, and test the voltage upon purchase to avoid defective products. After prying open the casing, avoid touching the internal electronic components. When replacing the battery, the marked side usually faces up or the negative terminal aligns with the contact position. Before closing the cover, gently clean the battery compartment contacts with a cotton swab to remove dust. The battery lifespan is approximately one to two years, depending on usage frequency, so regular testing is recommended. If the key doesn't work after replacement, it might be due to incorrect installation or loose contacts—simply double-check to resolve the issue.
