2 Answers
To replace the battery in a Beijing Hyundai Elantra key fob, follow these steps: 1. Press the silver button on the top of the key fob, hold the top, and pull out the mechanical key; 2. Insert the mechanical key into the gap, twist it slightly to pry open the key fob cover; 3. After removing the circuit board, you will see the battery. Take out the old battery and insert the new one, then reassemble the circuit board and cover the key fob. Taking the 2020 Beijing Hyundai Elantra as an example, it is a compact car with body dimensions of 4610mm in length, 1800mm in width, and 1450mm in height, with a wheelbase of 2700mm and a curb weight of 1319kg. The 2020 Beijing Hyundai Elantra is equipped with a 1.4T turbocharged engine, delivering a maximum horsepower of 130PS, a maximum torque of 211Nm, and a maximum power of 95.6kW, paired with a 7-speed dual-clutch transmission.
I do these small jobs myself, and replacing the battery for the Hyundai Elantra key is neither difficult nor complicated. There's a thin gap on the back of the key—use a thin plastic card or coin to gently pry open the cover, avoiding excessive force to prevent damaging the clips. Inside, you'll find a CR2032 coin battery. Carefully remove the old battery and dispose of it properly—don't just toss it away. Buy a new CR2032 battery from a supermarket or online, and when inserting it, ensure the positive side (marked) faces up and aligns with the slot. After securely closing the cover, immediately test the unlock and lock buttons to confirm they work. Keep a few spare batteries in your car in case of emergencies, so you're not stranded if the battery dies in the wild. If the key still doesn't work after replacing the battery, check for signs of drops or water damage—if found, visit a 4S shop for inspection. Remember to handle it gently to extend the key's lifespan, and don't rush the job to avoid frustration.
