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

First, you need to eject the metal mechanical key, as the key shell cannot be opened when the mechanical key is inserted. Press the physical button to eject the mechanical key, then turn the key horizontally and pry upwards along the gap. Gently pry open the key shell to separate the "head" and "tail" of the key. Stand the tail of the key upright, and you can lift the key cover from the gap on the back of the key. Once the key cover is removed, open it to replace the battery, then reassemble the key.
I also replaced the key battery for my Venucia T90 some time ago, and the process was quite straightforward. First, flip the key to the backside, and you'll notice a thin seam running along the edge—that's where the clip is located. Prepare a small flathead screwdriver or a plastic pry tool, gently insert it into the seam to pop open the cover—avoid using excessive force to prevent scratching the plastic casing. Once opened, the battery will be exposed, typically a small round CR2032 type. Use your fingers or tweezers to remove the old battery, being careful not to damage the internal contacts. Install the new battery with the correct polarity, usually positive side up. After replacement, press the cover until you hear a click to secure it, and that's it. Remember to test the button functions, such as remote unlocking, to ensure everything works properly. To prevent battery depletion in daily use, you can keep a spare key or check and replace the battery every two to three years in advance. When handling, make sure the environment is dry, and keep children away for safety first.
