The steps to replace the battery in a Volkswagen Tiguan key are: 1. Remove the mechanical key from the car key; 2. You can see an opening mark at the bottom of the key; 3. Use a small screwdriver to turn the opening mark at the bottom 90 degrees; 4. Rotate the outer shell of the key to open it; 5. Remove the old battery and insert the new battery into the car remote key in the reverse order of removal. Taking the 2017 Tiguan as an example, it is a compact SUV with body dimensions of: length 4506mm, width 1809mm, height 1685mm, a wheelbase of 2684mm, and a body weight of 1600kg.
Changing the battery in a Volkswagen Tiguan key is actually quite simple. I usually prefer to do it myself, and the steps are straightforward: First, prepare a small flathead screwdriver or even a coin, locate the clip gap on the back of the key, and gently pry it open to remove the cover. Avoid using too much force to prevent damaging the plastic. Remove the old battery—usually a small CR2032 coin cell—and pay attention to its original installation orientation: the positive side (the side with text) should face outward. Then, insert the new battery, reattach the cover, and press it firmly. Test the buttons to see if the car lights respond, ensuring everything works properly. The battery typically lasts over two years, so it's recommended to buy branded batteries from reputable stores to prevent leakage. After replacing, test the unlock function away from the car for safety, and avoid operating in humid areas as static electricity can interfere with the circuit. During routine maintenance, check the battery status to avoid unexpected malfunctions while driving.
Don't take safety issues lightly. A dead battery in the Volkswagen Tiguan key can cause accidental unlocking problems. Let me explain step by step: First, prepare small tools and find a quiet place to operate. Gently pry open the back of the key with a small screwdriver—don't use excessive force to avoid scratching your hands. Remove the old battery and replace it with a new CR2032, ensuring correct orientation—positive pole facing outward is crucial, otherwise the buttons may malfunction. Close the cover tightly and test if the buttons light up. If not replaced promptly, aging batteries may corrode internal circuits, increasing risks. It's best to check regularly, every two years, or replace when buttons become sluggish. Keep the operation area dry and test thoroughly before driving to avoid troubles on the road. Pay attention to details—the Volkswagen key has a compact design, so avoid damaging the edges or joints during prying, and you can complete the task easily.
