Press the silver button on the remote key fob to eject the mechanical key. Pry open the cover of the remote key fob. Remove the old battery from the key and replace it with a new one.
I recently replaced the battery in my Sportage key fob, and it was actually quite simple. First, go to the supermarket and buy a spare CR2032 coin cell battery—the silver, round type. Then, locate the seam in the middle of the key fob casing and gently pry it open along the edge using a coin or your fingernail; you'll hear a click. Inside, you'll see the old battery seated in a slot. Use small tweezers or a toothpick to remove it, remembering that the battery has a positive and negative side—the new battery should be inserted with the plus (+) side facing up. Finally, align the casing and press firmly until the clips snap back into place. The whole process takes no more than 5 minutes, but avoid using excessive force to open the casing, as the plastic clips can break easily. If you're really unsure, a watch repair stall by the roadside can do it for just 10 yuan.
I've helped my elderly neighbor replace key fob batteries several times. The process boils down to three key steps: preparing tools, removing the old battery, and installing the new one. All you need is a coin and a CR2032 battery, which are available at convenience stores. Flip the key fob to its backside, insert the coin into the middle seam of the casing, and gently twist to open it. Be careful with the fragile metal contacts inside - avoid touching them directly with metal tools. When removing the battery, note the positive pole marking and install the new battery in the same orientation. Remember to clean dust from the casing before reassembly to prevent poor contact. The Sportage key fob is quite sturdy and much easier to disassemble than Japanese car keys - it's perfectly manageable as a DIY job.
Last week I just replaced the Sportage key battery, summarizing a few key points: The battery model must be CR2032, buying the wrong one won't fit; When disassembling the shell, find the correct force point, which is at the groove on the back of the key; When installing the new battery, the metal side should face down and the printed side face up; The cover must click securely into place when closing. Special reminder: avoid repeatedly pressing the remote when the key battery is dead, as it will drain the backup power. If you find green corrosion marks in the battery compartment upon opening, clean them with an alcohol swab before installing the new battery. The whole process is as simple as replacing a phone SIM card.
