2 Answers
Mercedes-Benz GLA key battery replacement method is: 1. There is a battery cover on the back of the key, with a groove in the middle; 2. Press the groove to twist open the cover, remove the old battery and replace it with a new one. The Mercedes-Benz GLA is a compact 5-door, 5-seat SUV with body dimensions of: length 4427mm, width 1834mm, height 1610mm, and a wheelbase of 2729mm. The Mercedes-Benz GLA is equipped with a 1.3T turbocharged engine, delivering a maximum power of 100 kilowatts at 5500 rpm, and a maximum torque of 250 Nm between 1460 to 4000 rpm.
As an amateur technician who frequently repairs car keys, I know that replacing the battery in a Mercedes-Benz GLA key is actually quite straightforward. On the back of the key, there's usually a small groove or gap—just gently pry it open with a coin or a small flat-head screwdriver, but don't use too much force to avoid cracking the shell. Inside, you'll find a small round battery, model CR2032, which you can easily buy at any supermarket. When removing the old battery, pay attention to the positive and negative markings (there's a plus sign on the positive side), and insert the new battery with the positive side facing up. Snap the cover back on until you hear a click, then immediately test the unlock button to see if the car lights flash to confirm it's working. Common mistakes include prying too hard and cracking the plastic or inserting the battery backward, causing it not to work—just be patient. It's recommended to check the battery once a year to avoid being stranded outside in a panic when it dies.
