What is the battery model for Kia K4 key?
2 Answers
The battery model for Kia K4 key is CR2032. CR2032 is a lithium manganese dioxide battery, named according to IEC standards. Among them: C- indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R- indicates that the battery is cylindrical in shape, with F used instead if it is square; 20 indicates that the battery diameter is 20mm; 32 represents the battery height of 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 200-240mAh, varying by manufacturer. The shelf life of CR2032 is typically 5 years. If the manufacturer's production level is low or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. If the usage environment is ideal (sealed, room temperature, no moisture, etc.), the lifespan can be further extended to 8 years or even 10 years. Generally, replacing a car key battery only requires the following 3 steps: Step 1: Remove the mechanical key. Press the lock button on the side of the smart key to remove the mechanical key. Step 2: Open the battery cover. After removing the mechanical key, you can see a deep groove and a shallow groove at the top of the smart key. The deep groove is the keyhole, while the shallow groove is used to open the battery cover. Insert the mechanical key into the shallow groove and pry it outward to open the battery cover. After opening, you can see the coin cell battery. Gently pry it out to remove the battery. Step 3: Replace the new battery. Install the new battery, then reattach the battery cover and the mechanical key in sequence to complete the key battery replacement.
I remember the battery model for my Kia K4 key is CR2032, which is a common button cell battery that can be purchased at many electronics stores or online for around ten yuan. Replacing it yourself is quite simple: first, split the key into two parts, gently pry open the side clips—be careful not to break the plastic shell with too much force. After removing the old battery, install the new CR2032, making sure not to reverse the positive and negative poles, or it might not start. Last time my key ran out of power, the car door wouldn’t unlock properly, and I realized the battery had expired. It’s recommended to replace it every one or two years or check based on the dashboard prompts to avoid affecting the remote function. If unsure, you can spend a little money at the 4S shop to have them replace it for peace of mind.
