How to Open and Replace the Battery in the Venucia T90 Key?

Hold the remote key with one hand and pull out the key with the other. After pulling it out, the opening mark is located at the bottom of the remote key. Use a screwdriver to align with the described position and forcefully turn it 90 degrees. After turning, the outer shell of the key can be opened.
I've personally replaced the battery in my Venucia T90 key fob, and the whole process is actually quite simple but requires careful handling. When the key buttons stop responding, it's usually a sign that the battery is running low, typically a CR2032 coin cell model. The key fob shell is secured by plastic clips. Just find a gap along the edge and gently pry it open with your fingernail or a small tool – don't use too much force to avoid cracking the plastic. Inside, there's a small battery compartment. When removing the old battery, be careful not to touch the circuit board. Insert the new battery with the positive side facing up (the side with markings should be on top). When closing the shell, press firmly to ensure the clips snap into place – you should hear a click sound. Finally, test if the buttons respond normally. I recommend buying good-quality brand-name batteries to avoid premature failure from inferior products, and keeping spare batteries in your car for easy replacement. The entire battery replacement takes just 2-3 minutes. Before starting, clean your work surface to prevent losing small components.
I often replace the battery for the Venucia T90 key. First, check that the battery model is CR2032. Use a tool like a thin plastic sheet or your fingernail to carefully pry open the shell from the side seam of the key—avoid using metal tools to prevent damaging the plastic. Once opened, you'll see the battery compartment; gently remove the old battery. When installing the new battery, the positive side usually faces up—check the markings in the slot to ensure it's not inserted backward. Before closing the cover, make sure it's aligned properly and press firmly until you hear the locking click. Test the button functions to confirm everything works. It's recommended to do this in a well-lit area to avoid visibility issues. While it's not difficult, if it's your first time, practice with an old key to avoid mistakes that could damage the circuitry. Regularly replacing the battery can extend the key's lifespan and prevent driving inconveniences.
