The battery replacement for the Tiguan L key involves turning out the key head, removing the back cover in the direction of the arrow, using a suitable thin tool to pry out the battery from the battery compartment, placing the new battery, pressing it into the battery compartment in the direction of the arrow, and then replacing the cover. Tiguan L Seating Layout: The Tiguan L has been upgraded to a 7-seater model with a 2+3+2 seating arrangement, catering to the needs of larger families. The most notable feature is the flat-folding design of the third-row seats, providing flexible and versatile space configurations. When the third-row seats are folded down, the trunk capacity expands to 1780L, easily meeting various travel demands of consumers. Tiguan L Power: The Tiguan L 2.0T comes in two versions with different power outputs. The low-power 2.0T version delivers 186 horsepower with a maximum torque of 320 Nm, achieving maximum torque between 1500-4000 rpm and maximum power between 4100-6000 rpm, paired with a 7-speed dual-clutch transmission.
Last time I changed the key battery for my Tiguan L by myself, and the steps were quite simple. First, prepare a new CR2032 coin cell battery, then pull out the metal key blade. Use your fingernail or a screwdriver to gently pry open the shell along the seam. Pay attention to which side of the old battery is facing up, and place the new battery the same way—otherwise, it won’t work if installed backward. Finally, snap the shell back together, reinsert the key, and test the remote functions. The whole process takes just three minutes—no need to waste money at the dealership. You can buy the battery online for just five yuan with free shipping, and it lasts over a year. If your key starts responding slowly, it’s time to replace the battery—don’t wait until it stops working completely.
I often help friends with replacing key batteries. On the back of the Tiguan L key, there's a latch—press it to pull out the mechanical key. Then, use a flathead screwdriver to gently pry open the shell along the gap, being careful not to apply too much force to avoid cracking the plastic. Once open, remove the old battery, making sure to remember the CR2032 model to avoid buying the wrong one, which is available at convenience stores. Insert the new battery with the printed side facing up, and when closing the cover, ensure the tabs align properly. After replacement, test the sensitivity by pressing the lock button, and it's best to do this on a balcony to prevent the battery from falling.
