How to Replace the Battery in a Tourneo Key?
2 Answers
First, press the button on the car key to pop open the back cover, gently tap it to remove the old battery, and then insert the new battery. The steps to replace the battery in a Tourneo key are as follows: 1. First, disassemble the car key. Some car keys have screws that need to be removed first, then pry open the key cover with force. 2. If there are no screws, you can pry it open directly. Once opened, you will see the coin cell battery. Most car remote keys use CR2032 coin cell batteries. CR stands for lithium-manganese coin cell battery with a voltage of 3 volts, and 2032 indicates the battery diameter is 20mm and thickness is 3.2mm. 3. The specific model number is labeled on the original car battery.
Recently helped a friend fix a few keys, and battery replacement is quite common. The Tourneo key generally uses a CR2032 coin cell battery, and the steps are straightforward: Prepare a small flathead screwdriver or a similar tool. There's a thin seam or clip on the back of the key; align and gently pry it open, avoiding excessive force to prevent damaging the plastic casing. Once opened, you'll see the battery, usually seated in a slot. Carefully remove the old battery, noting which side is the positive terminal (usually the round side faces up). Insert the new battery in the same orientation, ensuring the positive side is up. Finally, align and press the back cover firmly until you hear a click to confirm it's properly seated. It's best to test the remote function immediately—locking or unlocking should respond quickly. The whole process takes just a minute or two, and it's recommended to check the battery every two years to avoid unexpected failures.
