How to Replace the Battery in a Volkswagen Tiguan Key?
2 Answers
To replace the battery in a Volkswagen Tiguan key, first pull out the mechanical key. Then, use a small screwdriver to turn the bottom opening position 90 degrees. Next, rotate the outer shell of the key to open the key cover. After opening, remove the internal battery and replace it with a new one. Below is an introduction to the Volkswagen Tiguan: 1. Transmission: The Tiguan is equipped with industry-leading 1.8TSI and 2.0TSI engines, paired with a 6-speed manual transmission or an Aisin 6-speed automatic transmission, delivering strong power and higher fuel efficiency. 2. Configuration: The Tiguan comes standard with ESP body stability system, EBD electronic brake force distribution, and ASR traction control system.
I used to tinker with my Volkswagen Tiguan key fob battery quite often, and it's actually not difficult. First, find a small flathead screwdriver or coin, and gently pry open the casing from the small gap on the side of the key—don't use too much force to avoid scratching the plastic. Once opened, you'll see the round coin cell battery, usually a CR2032 model, which can be easily bought for a few bucks at an electronics store or online. Note whether the positive side of the old battery faces up or down, and make sure the new one is placed the same way—don't reverse it, or the current won't flow. After installing, press the cover firmly until it clicks shut. Finally, test the lock and unlock buttons to confirm they respond normally. A quick tip: the battery lasts about two to three years; if the buttons start responding sluggishly, it's time to replace it, or you might face trouble if it fails unexpectedly. It's best to keep a spare battery in the car for emergencies. Wear gloves when handling to avoid static electricity affecting the circuit, and be careful not to apply too much force—the Tiguan key casing is delicate and can break easily.
