How to Open the Mingtu Key to Replace the Battery?
3 Answers
Here is the detailed tutorial for replacing the battery in the Mingtu key: 1. Take out the spare mechanical key, then gently pry open the key casing along the gap. Once the casing is opened, you will see the key battery, and you can remove the old battery for replacement. 2. Precautions: After opening the key casing, be careful not to damage the chip. If the chip is damaged, you will need to replace it with a new one. 3. Usage Cycle: The remote key for the car generally contains a battery, which can last for about 2 to 3 years. Once the battery is depleted, the car owner will need to replace it.
Last time I changed the battery for my Mistra's key fob, I found it was actually quite simple. First, press the mechanical key release button on the back of the fob and pull out the metal key blade. Then use a plastic pry tool or your fingernail to gently pry open the casing along the seam on the side - be careful not to use excessive force. Once opened, you'll see the button battery inside, which is a CR2032 model. Panasonic or Sony brands work fine. To remove the old battery, just push it out with a toothpick. When installing the new one, remember to place it with the positive side facing up. Finally, align the top and bottom covers and press them together until you hear a click. The whole process takes about five minutes. I even bought a 10-pack of spare batteries online for backup, which cost less than half the price of getting them from the 4S shop.
I helped my neighbor replace the battery in their Hyundai Mistra key fob, which mainly involves four steps. First, flip the key fob to the backside and press the small square button to release the mechanical key blade. Then, insert a coin into the side gap and gently twist to separate the outer shell. Inside the battery compartment, there's a spring clip - just use your fingernail to pry out the old battery (remember it's a 3V CR2032 model). Key point: when installing the new battery, make sure the side with the text faces toward the key buttons. Last time my neighbor installed it backward, causing the remote sensing to fail, and we had to reopen and reinstall it correctly. Finally, when closing the case, first align the clips on the battery compartment side, wait for the crisp click sound, then press the other side to ensure a snug fit without any looseness.
