First, press the button on the key to remove the metal mechanical key. Then, use your left thumb or a small flat-head screwdriver to pry open the seam of the remote key upwards. Apply a little force to open one end of the battery cover. Next, remove the old battery and insert the new one into the battery slot. Finally, press the key cover back into place. Additional relevant information is as follows: 1. The Volkswagen Tiguan is a car produced by SAIC Volkswagen, with dimensions of 4506mm in length, 1809mm in width, and 1685mm in height, and a wheelbase of 2684mm. 2. The Volkswagen Tiguan comes standard with ESP body stability system, EBD electronic brake force distribution, and ASR traction control across all models.
I've been driving the Tiguan for several years and have changed the key battery quite a few times myself. On the back of the Tiguan key, there's usually a small slot or button—just press gently or pry it open with your fingernail to remove the back cover. The battery model is almost always a CR2032 coin cell; opt for a reputable brand and avoid cheap knockoffs. When removing the old battery, pay attention to the electrode orientation. Insert the new battery the same way, with the positive side facing down—reversing the direction may cause malfunction. After closing the key, test the lock/unlock function first to ensure there are no gaps that could let water in. I recommend replacing the battery in the spare key as well to avoid the hassle of accidentally locking it in the car. Make it a habit to check the battery life annually—it can save you from many unexpected situations.
As a DIY beginner, I just replaced the battery in my Tiguan key myself, and the process was simple and cost-effective. There's a hidden button on the side of the key—just press it gently and the back cover pops open. Be careful not to use too much force when removing the old battery to avoid damaging the plastic clips. The new battery should be a CR2032 model, which you can easily find in supermarkets or online. It's recommended to buy the same brand to ensure the size fits perfectly. When installing the new battery, align it with the slot, making sure the positive side faces inward, and press it firmly into place. Then, snap the cover back on and lock it securely. After replacement, immediately test the unlock and lock buttons to see if they light up or respond, ensuring everything works properly. Doing it yourself saves both the cost and time of visiting a 4S shop. It’s also convenient to keep spare batteries in the car—just in case you run into trouble on a long trip.
