What is the battery model for Cadillac XT4 key?
2 Answers
The battery model for Cadillac XT4 key is CR2032. CR2032 is a lithium manganese dioxide battery, named according to the IEC standard. 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 has a diameter of 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 varies between 200-240mAh, depending on the manufacturer's standards. The shelf life of CR2032 is typically 5 years, but if the manufacturing level is low 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.), 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 slot and a shallow slot at the top of the smart key. The deep slot is the keyhole, while the shallow slot is used to open the battery cover. Insert the mechanical key into the shallow slot 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.
As a Cadillac XT4 owner, the key fob battery model is CR2032, that common small coin cell. A few months ago my key started responding sluggishly, and the dashboard displayed a low battery warning. I quickly checked the manual to confirm it was indeed CR2032. I bought several at the supermarket for 10 yuan, then used a small screwdriver to gently pry open the key casing for replacement - found it super easy. I recommend keeping one or two spare batteries in the car, so if the key fails in remote areas, it won't disrupt your trip. Regular checks are crucial too, especially after about a year and a half of driving when batteries tend to drain. My current routine is replacing it every 18 months, while also cleaning dust inside the key to prevent contact issues that might cause other problems.
