The body dimensions of the Mercedes-Benz GLA200 are 4417mm in length, 1804mm in width, and 1494mm in height.

Last time I changed the battery for my Mercedes-Benz GLA200 key, I found it super easy and quite enjoyable as a hands-on task. The key back cover usually has a small button or clip – just press it gently to slide open the cover, revealing the coin cell inside. Remember, the battery model is CR2025, so don’t get the wrong one; you can buy it at an auto parts store or supermarket. Use your fingernail or a small screwdriver to gently pry out the old battery, being careful not to damage the slot. When installing the new battery, make sure the positive side faces upward, secure it in place, and then close the cover. Test the remote buttons to ensure they work; if not, double-check the battery orientation. The battery costs just a few bucks and lasts about a year—keep a spare in your car just in case. The whole process takes just two or three minutes, saving money and giving you a real sense of accomplishment.
As a car owner, I recommend beginners take their time when replacing key fob batteries—safety first. The Mercedes-Benz GLA200's key is quite delicate, so avoid using excessive force when prying open the back cover to prevent surface scratches. The battery is hidden inside; use a small tool like a pen tip or tiny screwdriver to gently pry it out, being careful not to cut your fingers. The battery model is CR2025—make sure to install it with the correct polarity. Test all key buttons immediately after replacement to ensure remote functionality. If the battery feels loose, it may cause malfunctions; repeat the steps until it sits securely. This small task takes about five minutes, but patience is key to avoid damaging the fob. Pay attention to early warning signs like delayed response (e.g., difficulty unlocking doors) and replace the battery proactively.
