When I first tried replacing the battery for my Bestune B70 key, I was quite nervous. The key is a remote type with a small groove or gap on it. It's advisable to prepare a small flat-head screwdriver or a credit card, align it with the gap, and gently pry it open. Be careful not to use excessive force to avoid breaking the clips or scratching the surface. Before removing the old battery, check the model number clearly; it's usually a CR2032 coin cell battery, which can be bought new for a few bucks at supermarkets or online. After replacement, carefully reassemble the shell and snap it tight. Test if the unlocking function works properly. If unsure, consult the vehicle manual or search for tutorial videos on your phone to avoid damaging it through improper disassembly, which could lead to costly repairs. DIY is convenient, but being meticulous is key.
Changing the battery for the Bestune B70 key feels like a piece of cake. There's usually a small notch on the edge of the key—just pry it open with your fingers or a bank card, no tools needed at all. The battery model is CR2032, available at any convenience store, and the whole process takes just ten seconds. After inserting the new battery, snap the key back together and test it with a couple of clicks. A quick tip: replace the battery every two years or so to avoid remote failure and unnecessary delays. Doing it yourself saves you dozens in repair fees—simple, cost-effective, and totally worth it.
