2 Answers
Haima replacement key battery steps are as follows: 1. Open the folding key and forcefully separate the upper and lower parts of the remote. 2. Disassemble the lower part's upper and lower covers, remove the circuit board, and take out the old battery. 3. Insert the prepared new battery into the circuit board with the positive pole facing downward, place it into the lower part of the shell, and snap the upper and lower parts of the remote back together. Below is some information about remote keys: 1. A car remote key utilizes the wireless remote control function of the central locking system, allowing doors to be unlocked and locked from a distance without inserting the key into the lock. 2. Based on their usage methods, they can be divided into three categories: active working mode, passive working mode, and coil induction mode.
Last time the remote range of my Haima car key became shorter, so I replaced the battery myself. First, confirm the battery type—Haima keys generally use CR2032 coin cell batteries, which can be bought at hardware stores or supermarkets. Use a small screwdriver or coin to gently pry open the shell from the small groove on the back of the key, being careful not to break the clips. Once opened, you’ll see the old battery secured in its slot—use a toothpick or fingernail to lift it out. Insert the new battery in the same orientation as the old one, with the positive side (the side with text) facing up. Then align the shell clips and press gently until you hear a click, indicating it’s properly secured. Finally, test if the remote function has been restored. The whole process takes just a few minutes—doing it yourself is hassle-free and saves money. If you’re unsure, check online video tutorials for a clear visual guide.
