Before replacing, it's best to first understand the battery model of your car key, which is usually indicated in the vehicle's user manual. Then, select a new key battery according to the specified model. Below are the steps to replace the battery in a Mercedes-Benz GLA: 1. On the side of the Mercedes-Benz GLA remote, there is a PUSH button. Press this PUSH metal head and pull out the mechanical key. 2. After removal, a small groove and a slit will be exposed at the top. Pry it open with force, and the key will split into two halves as you apply pressure. 3. The side with the circuit board is where the battery inside the key is located. 4. Flip it over, remove the old battery, and place a CR1632 battery in the metal frame position. 5. Then, place the circuit board back in its original position, close the two halves together, and you're done.
Replacing the battery in the Mercedes-Benz GLA key is actually quite simple, and I've done it several times myself. There's a small gap on the key; you can gently pry open the plastic cover with a coin or a hard card, but don't use too much force to avoid damage. The small battery inside is a CR2032 model, just carefully insert it with the positive side facing up. If the battery is low, the remote control distance will shorten or the buttons won't respond, which means it's time to replace it. Generally, changing it every two years is enough. Buying a new battery yourself only costs a few dollars, saving both time and money compared to going to a repair shop. Remember to regularly check the key's status to avoid affecting locking and unlocking at critical moments due to a dead battery.
I've tried various car key DIYs myself, and the Mercedes-Benz GLA is quite easy to disassemble. Just insert a flat tool into the key slot and pry open the plastic cover. Remove the old battery, which is a CR2032 model—make sure not to place it backwards, or it won't work. After installing the new battery, snap the cover back on until you hear a click, and you're done. The whole process takes less than 5 minutes—fun and hassle-free. If the battery contact is poor, you can clean the electrode plates and try again. It's recommended to test the remote functions after each battery replacement to ensure everything works properly before finishing up.
