How to Replace the Battery in the New Mercedes-Benz ML230 Key?
1 Answers
Replacing the battery in a Mercedes key involves the following three steps: 1. First, push the small switch tab on the tail of the remote to the right, which will release a manual key. 2. After pulling out the key, gently insert it into the slightly larger hole on the back of the key slot. Insert it about one centimeter until the remote's battery cover hits the latch, then gently pry to open the cover. 3. Open the cover by hand to reveal the remote's battery. Tap the battery lightly to pop it out and remove it. If the pin is difficult to pull out, replace it with a new battery, reattach the key cover, and then reinsert the manual key to complete the process.
