What is the battery model for Cadillac XT4 key?
4 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.
Cadillac XT4 owners all know that the key fob uses a CR2032 battery, and this little thing is truly amazing. I enjoy doing these detailed tasks myself. When disassembling the key, first pull out the mechanical key part, then gently open the back cover with a flat-head screwdriver. Be careful not to use too much force to avoid damaging the plastic clips. The battery itself has a stable 3-volt performance, but its lifespan is about one to two years, depending on usage frequency. I've tried different brands of CR2032, and even the supermarket ones are quite durable—a single battery can last a month or so without any issues. Key maintenance isn't just about replacing the battery; I also regularly check the contacts for oxidation and wipe them with a soft cloth to ensure smooth connectivity. This kind of DIY fun saves me the hassle of queuing at the dealership.
The Cadillac XT4's key fob battery is a CR2032 model, which I've confirmed in the manual. If you notice weakened key signals during use, it may be a sign of impending battery depletion—don't wait until it fails completely. Based on my experience, the battery typically lasts about a year and a half, with faster depletion during hot summer months. Replacing the battery is quite simple—just purchase a new one for a few dollars and do it yourself in minutes. A good backup plan is to keep an unopened spare battery in the car for emergencies.
