To replace the key battery for Fit, follow these steps: 1. Press the button on the electronic key and remove the mechanical key; 2. Insert a coin into the slot and turn it clockwise to separate the key into two parts; 3. Use a toothpick to remove the old battery and replace it with a new one of the same model; 4. Snap the two parts back together, press the edges, and ensure the clips return to their original positions. The Fit is a compact 5-door, 5-seat hatchback with the following dimensions: length 4109mm, width 1694mm, height 1537mm, and a wheelbase of 2530mm. It is equipped with a 1.5L engine and a CVT transmission, delivering a maximum power of 96 kW and a maximum torque of 155 N·m. The drivetrain is front-wheel drive, with a MacPherson strut front suspension and a torsion beam rear suspension.

I recently replaced the battery in my Fit's key fob myself, and the process was quite straightforward. First, you need to confirm whether the key is the Crystal Diamond folding type or the smart key type - the battery is usually a CR2032. Use a small flathead screwdriver or coin to align with the groove on the back of the key fob, then gently pry open the casing. Inside, you'll see the round coin cell battery secured in its slot; carefully remove it using tweezers or your fingernail, being careful not to damage the circuit board with excessive force. When installing the new battery, pay attention to the polarity - the metal side should face downward against the contacts. When closing the casing, listen for the 'click' sound to ensure proper engagement. Finally, don't forget to test both the locking and ignition functions. The whole procedure takes about five minutes and saves you over a hundred yuan compared to visiting the dealership.

I often help friends replace the battery in their Fit keys. Prepare a CR2032 battery and pull out the mechanical key from the shell. There's a seam in the middle of the key case—run your fingernail along it to pry it open. When removing the old battery, pay attention to whether the positive side faces down or up; taking a photo for reference is the safest. Install the new battery in the original orientation, ensuring the metal contacts are fully aligned. When closing the case, make sure all four clips snap securely into place, then test all button functions. Remember to choose Panasonic or Sony batteries for better durability, as low-quality batteries are prone to leakage and can corrode the circuit.

Just changed the CR2032 battery for my Fit's key last week, which is easily available at convenience stores. The safest way to open the key is using a fingernail or plastic card, as metal tools may scratch the casing. Remember the orientation of the old battery when removing it, and ensure the metal contacts are fully engaged when installing the new one. After reassembly, test the key's signal range - reduced remote distance may indicate poor battery contact. Lay a cloth on the work surface to prevent losing small parts, and avoid excessive force during the process to prevent damaging internal clips.
