2 Answers
Here is the method to replace the battery of a Roewe 350 car key: 1. Pop open the key. 2. Use a small flathead screwdriver to rotate the screw located in the remote key storage slot to the ON position. 3. Gently pry the locking screw end of the remote battery seal cover with the screwdriver, then remove the remote battery and seal cover. 4. Use tweezers to take out the remote battery. 5. Install the new battery. Replacing the car key battery requires caution, as any mistake could damage the circuit board inside the key. Before replacement, the car owner should carefully review the battery replacement diagram. When disassembling the key, pay attention to the original positions of each component and try to choose an original battery. During installation, carefully identify the positive and negative terminals of the battery to avoid incorrect placement. Additionally, be mindful of the seal ring at the bottom of the key to prevent damage during replacement, as this could also lead to circuit board damage.
When I replaced the battery for my Roewe 350 key fob myself, I found it to be quite simple. There's a notch on the back of the key—just gently pry it open with a fingernail or small screwdriver to reveal the interior. The battery is a CR2032 coin type. Make sure to observe which side the positive pole of the old battery faces (usually the raised side) and insert the new battery in the same orientation. Never put it in backward, or the key may malfunction. I like to wipe the contact points with an alcohol swab first to ensure they're clean and conductive. After snapping the cover back on, press the car lock button to test if it works normally. Key fob batteries typically last 1-2 years. I bought a whole pack online for just 10 yuan—it's handy to keep a few spares at home. If the key slot is too tight, don't force it open to avoid damaging the plastic casing. The whole process takes less than 5 minutes, much easier and cheaper than visiting a repair shop.
