What is the battery model for Ford car keys?

[LaHaley]

Ford key battery model is CR2025. CR2025 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 the battery diameter is 20mm; 25 represents the battery height is 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 140-170mAh. The shelf life of CR2025 is typically 5 years. If the manufacturer's production level is not high or quality control is poor, its lifespan can be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. If the usage environment is ideal (sealed, room temperature, free from moisture, etc.), its lifespan can be further extended to 8 years or even 10 years. Generally, replacing a car key battery only requires the following three 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 the top of the smart key has a deep groove and a shallow groove. 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. Once opened, 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 mechanical key in sequence to complete the battery replacement.
