3 Answers
The method for replacing the key battery of the new Mercedes-Benz CLS260 is as follows: 1. Press the button on the back of the key, push the back cover forward to open the key, and the battery is located in the slot beside it; 2. Pry open this slot to remove the old battery and replace it with a new one; 3. Next, reattach the back cover of the key. Once the back cover is securely installed, the battery replacement is complete. Symptoms of a low battery are as follows: 1. The lifespan of a Mercedes key battery is generally two years, while the original factory battery can last up to six years. When the key battery is low, the Mercedes vehicle will display two indicators: one is that pressing the ignition switch will prompt a message on the dashboard to replace the key battery. 2. Press the lock or unlock button on the key. If the indicator light on the key dims or does not light up, it indicates that the key battery needs to be replaced.
Just helped a friend replace the battery in their CLS260 key fob a couple of days ago, and it's actually quite simple. There's a small notch on the back of the key—just insert a coin or a small flathead screwdriver and gently pry to open the casing. The battery is a CR2025 coin cell, so make sure not to get the wrong type. When removing the old battery, pay attention to the polarity, and install the new one in the same orientation. You'll hear a click when closing the cover, indicating it's properly secured. After replacement, remember to test the lock/unlock functions. If you notice the remote range getting shorter, it's time to replace the battery—don't wait until it's completely dead and causes inconvenience. When buying batteries online, opt for reputable brands like Panasonic. If purchasing from a supermarket, check the production date to avoid old stock. The key casing is plastic, so avoid using excessive force when prying to prevent scratches and keep it looking good.
I'm quite familiar with replacing Mercedes key batteries. The CLS260's key design is quite reasonable. First, locate the small notch on the back of the key - you can pry it open using a small steel ruler or thin card. The battery inside is CR2025 specification, smaller than a fingernail. When installing, make sure the silver side faces upward; it won't work if installed backwards. The whole process takes just three minutes, and even women can do it without difficulty. Here's a little tip: if the remote doesn't work after battery replacement, try pressing and holding both the lock and unlock buttons simultaneously for ten seconds to reset the system. When buying batteries at the supermarket, be careful not to pick CR2032 by mistake - although similar in size, they differ in thickness. It's recommended to perform the replacement in a dry environment as moisture can oxidize the battery contacts. Remember to recycle the old battery properly; don't discard it carelessly and pollute the environment.
