What is the electronic model of the Elantra car key battery?

Elantra key battery model: CR2032. Owners must ensure to purchase the same model battery when replacing it. Below is relevant information about the key: 1. Steps to replace the Elantra key battery: Pull out the mechanical key, and you will see a notch in the middle of the plastic shell. Use a flat-head screwdriver to pry it open—there are no screws, just pry it open. Remove the mechanical key, use a coin to twist along the small groove on the key's flat surface to open it. Replace it with a CR2032 Panasonic lithium battery, positive side down. After replacement, firmly press the separated key parts together to snap the buckle closed. 2. A remote key refers to a key that can unlock and lock the door from a distance without inserting it into the keyhole. Its biggest advantage is: regardless of day or night, there's no need to locate the keyhole, allowing convenient remote locking and unlocking.
I bought an Elantra a few years ago, and the car key uses a CR2032 battery, which is quite common for button cells. If the key isn't working properly, it's most likely due to a dead battery. Last time, I replaced it myself: first, gently pry open the key shell with a small flat-head screwdriver, being careful not to damage the clips. Remove the old battery, insert the new CR2032 with the correct polarity, and then snap the shell back together. After replacing, remember to test the locking function to avoid any malfunctions. For daily use, it's recommended to regularly check the key signal, especially when the unlocking distance becomes shorter—that's when it's time to replace the battery. I use Panasonic brand batteries; they're durable and affordable. Also, key models may vary by year—older versions have a folding design with slightly different battery placement, but CR2032 is definitely the right choice.
As a frequent driver of the Hyundai Elantra, I've found that the core of the remote key is the CR2032 battery—a fixed model often overlooked. When the key responds sluggishly, it's usually due to a drained battery causing weak signals. My biggest fear is it jamming when locking the car. I recommend opting for OEM batteries or high-capacity versions like the Sony CR2032, costing just a few bucks each. Replacing it yourself is super easy: first, close the car doors to avoid mishaps, then use a tool to pry open the key slot, remove the old battery, and insert a new one. Avoid no-name brands to prevent leakage and circuit damage. The Elantra's key internals are delicate, and a dead battery can affect the central control system, so I check mine every two years to avoid embarrassing situations when out and about.
