I remember last time when I replaced the key battery for my Mercedes-Benz C260L, I used a little trick. There's a small button on the back of the key – just press it gently and the casing pops open, revealing a small coin cell battery. The battery model is CR2032, which you can easily find in supermarkets or on e-commerce platforms. Make sure to insert it with the positive side facing up, not the wrong way around. When putting it back together, align the edges and press firmly – the whole process takes less than 5 minutes, simple and cost-effective. If the battery runs out, the car's dashboard will display a 'key battery low' warning, so it's best to replace it promptly to avoid being unable to unlock the doors. I recommend keeping a spare battery in the car just in case of sudden power loss, preventing being stranded outside. The key itself is quite durable, so avoid prying or using tools forcefully, as this can easily damage internal components. Regularly checking the battery life is also a good habit.
Replacing the battery in a Mercedes C260 key isn't difficult, I've done it several times. First, there's a small indented button on the back of the key - press it gently to open the casing. See the CR2032 battery inside? When replacing it, make sure the positive side aligns with the metal contacts for proper connection. I recommend using a plastic tool or your fingernail to gently pry it out, avoiding metal objects that might scratch the circuit board. The battery typically lasts about two years - when the key starts responding slowly, that's your signal. If buttons don't work after replacement, the contacts might be dirty; just clean them with a cotton swab. Remember to close the casing properly before testing - dust and water protection is crucial. This procedure works for many Mercedes models, mastering it saves you a trip to the dealership.
