What is the battery model for Hyundai Elantra's key?
2 Answers
The battery model for Hyundai Elantra's key is CR2032. Its working principle is: the key emits radio waves, which are received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and then the system's actuator performs the unlocking or locking action. Taking the 2016 Fashion Edition Hyundai Elantra as an example, its body dimensions are: length 4750mm, width 1775mm, height 1445mm, wheelbase 2700mm, and fuel tank capacity 50L. The 2016 Fashion Edition Hyundai Elantra has a front MacPherson independent suspension and a rear torsion beam non-independent suspension. It is equipped with a 1.6L naturally aspirated engine, with a maximum horsepower of 128PS, maximum power of 94kW, and maximum torque of 156Nm.
I used to drive a Hyundai Elantra, and the car key battery was usually a CR2032 coin cell. When the remote stopped working, I replaced it myself several times. The method is simple: use a coin or a small screwdriver to pry open the key casing, remove the old battery, pay attention to the positive and negative polarity, and install a new CR2032. This battery is easy to find in supermarkets or online stores, costing about one yuan. Normally, it lasts for over a year. If it frequently malfunctions, replace it earlier. Remember not to touch the key's circuit board to avoid damage. In winter, the battery drains faster, so keeping it in your pocket to stay warm can extend its lifespan. Overall, the Elantra key design is stable, and CR2032 is the standard model. Choose a high-quality one to avoid leakage issues. Doing it yourself saves time and money, and keeping one or two spare at home is very convenient.
