How to Replace the Key Battery for the New Mercedes-Benz E230?
3 Answers
To replace the key battery for the new Mercedes-Benz E230, follow these steps: Start from the tail end of the key and push upwards on the marked switch. The hidden mechanical key will pop out. Remove the mechanical key, then use it to press against the marked position at the tail end of the key to open the key casing. Inside, you will find the battery located relatively deep. Insert a tool into the gaps on both sides to remove the old battery and replace it with a new one. The Mercedes-Benz E230 has a body length of 4818mm, width of 1822mm, height of 1452mm, and a wheelbase of 2854mm. It is equipped with a 2.5-liter V6 engine.
I just replaced the battery in my E230 key the other day, and the steps were actually quite simple. First, locate a small indentation on the back of the key, use a coin to twist it gently, and the metal cover will pop open. Pay attention to the original battery model, which is CR2032, and install the new battery with the positive side facing up. Last time I bought a Panasonic button battery at the supermarket for just ten yuan. After installing it, press the metal cover back until you hear a 'click' sound to ensure it's properly in place. If you can't manage it yourself, a visit to the 4S shop might cost around a hundred yuan in labor fees. Usually, keep the key in your pocket and avoid squeezing it with coins; the battery can last two to three years.
I remember the first time my daughter helped me replace the battery in my Mercedes key fob – didn’t even need a screwdriver. The E230 generation key has a sliding mechanism: press the silver button on the back with your thumb while pushing the key casing sideways to open it. The key is avoiding brute force – those plastic clips snap easily. The battery compartment sits beneath the circuit board; carefully remove the old battery before inserting the new one. Pro tip: lay a microfiber glasses cloth underneath when working. Last time I did this on the kitchen counter and ended up scratching the key casing.
