What is the battery model for Nissan X-Trail car key?

The battery model for X-Trail car key is CR2032. CR2032 is a lithium manganese dioxide battery, named according to IEC standards. The naming convention is as follows: C - Indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R - Indicates the battery shape is cylindrical, if it were square, F would be used instead; 20 - Indicates the battery diameter is 20mm; 32 - Indicates the battery height is 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, the lifespan can be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can be extended further to 8 years or even 10 years. For X-Trail models such as the Fashion Edition, Comfort Edition, and Luxury Edition, the key battery model is CR2032. Replacing the key battery requires only 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 will see a deep slot and a shallow slot at the top of the smart key. The deep slot is for the keyhole, while the shallow slot is used to open the battery cover. Insert the mechanical key into the shallow slot and pry it open to reveal the coin battery. Gently remove the battery. Step 3: Replace the battery. Insert the new battery, then reattach the battery cover and mechanical key in order to complete the replacement. There are two important points to note when replacing the X-Trail car key battery: The key uses a coin battery, model CR2032, so make sure not to buy the wrong type. The battery replacement should be done quickly because the key has a memory function. If it loses power for more than 5 minutes, it will need to be rematched.
That day I happened to change the car key battery for my friend's X-Trail, and after some effort, I figured it out. The battery model is usually CR2025, but older models might use CR2032, so I suggest you first open it up and check the stamped numbers on the old battery to confirm. Changing it yourself is quite simple—just use a coin to insert into the slot on the side of the key fob and give it a gentle twist to open. Be careful not to use too much force and break the plastic clips. The battery costs about five bucks at the supermarket. When installing the new battery, remember to place it with the positive side up; if it's installed backward, the buttons won't respond. After replacing it, test the key from a distance—if the remote range shortens, it's likely due to poor contact and needs to be reinstalled. Also, a quick reminder: don't cheap out and buy off-brand batteries, as leaking fluid can corrode the circuit board and ruin the entire key.
I'm someone who enjoys studying electronic components. The most common battery model for the X-Trail car key is the CR-series button battery, specifically like the CR2025 which is 2.5mm thick or the slightly thicker CR2032 at 3.2mm. Just take a screwdriver to open the back cover, and you'll see the model number printed on the battery surface. When choosing a battery, don't just look at the size; the voltage must be 3V. Some cheap batteries have unstable voltage, which can cause remote control failure. The battery life is usually just one or two years—when the remote control range shortens, it's time to replace it. During installation, make sure to clean the battery compartment thoroughly, as finger grease can lead to poor contact. I've changed my car key battery twice in four years and discovered a trick: don't keep the key and phone in the same pocket—electromagnetic interference drains the battery quickly.
