There is a groove on one side of the key. Use a flathead screwdriver wrapped in cloth to gently pry it open. Inside, you will find the battery. When replacing the battery, pay attention to the model number on the battery. The Mitsubishi Outlander uses a coin cell battery, and you can replace it by simply opening the key casing. Below are the detailed steps for replacing the key battery in a Mitsubishi Outlander: 1. Face the side with the Mitsubishi logo toward you. Wrap the tip of a flathead screwdriver with cloth and insert it into the notch on the remote switch casing to open it. 2. Remove the remote transmitter from the key casing, then follow the steps to open the transmitter. 3. Remove the old battery. 4. Install the new battery with the + side facing down. 5. Reassemble the transmitter. 6. Place the reassembled transmitter back into the remote casing and secure the switch casing. 7. Check and confirm the installation.
Last time I replaced the Outlander key fob battery, it was quite simple. First, prepare a CR2032 coin cell battery and a flathead screwdriver. There's a small groove on the back of the key fob - gently pry open the casing with the screwdriver, being careful not to apply too much force and damage the plastic clips. After opening, remove the old battery, paying special attention to the positive/negative polarity markings inside the Outlander's battery compartment. When installing the new battery, make sure the positive side faces upward and press it in gently until you hear a click. Before reassembling, test the unlock function by pressing the buttons a few times - if the lights blink normally, you're good to go. Finally, align and snap the cover back into place. The whole process takes about five minutes. I recommend using quality batteries like Panasonic or Sony for better durability.
Changing the key fob battery yourself can save you a lot of money. The dealership charged me 300 yuan! You just need to buy the correct battery type - the Outlander uses a CR2032 battery, which costs only about 10 yuan at supermarkets. Locate the small slot near the metal ring of the key, and you can pry it open with a coin or your fingernail. Remember the orientation of the old battery before removing it, and make sure not to install the new battery backwards. If the casing is particularly tight, try using a hair dryer to heat it for a few seconds to soften the plastic. After replacing the battery, immediately test the trunk button and remote start function. Once I forgot to test it and couldn't start my car. Also check the key's sealing ring and replace it if it's aged.
