What is the battery model for the 2019 Nissan X-Trail car key?

The battery model is CR2032. It 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 shape is cylindrical, and if it is square, F is used instead; 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 is around 200mAh. CR2032 typically has a lifespan of 5 years. If the manufacturer's production level is not high 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, free from moisture, etc.), the lifespan can be further extended to 8 years or even 10 years. The usage time of the car remote key battery is closely related to the frequency of use. The more frequently it is used, the shorter the usage time will be. If the remote key battery runs out, you can directly use the mechanical key to open and start the vehicle. The battery used in car remote keys is a button cell, mainly using three types of batteries: CR2016, CR2025, and CR2032. For the specific model used in each vehicle, owners can refer to the battery model in the user manual for replacement. Button-type CR2016 battery: The usage rate of this battery in car key remotes is very high, making it one of the most common car remote batteries. The battery voltage is 3V, while general car key batteries are powered by 9V, so three batteries need to be replaced each time. Examples include: Honda, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter 20mm, thickness 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than CR2016. However, some car keys still use it. It is thicker than the 2016 model but has a relatively higher storage capacity. CR2025 specifications: battery diameter 20mm, thickness 2.5mm. This type of battery is also commonly used in audio remotes. Button-type CR2032 battery: Its thickness is twice that of CR2016. The 3V-CR2032 lithium manganese battery belongs to the lithium-manganese dioxide structure. The positive electrode material is chemically very stable manganese dioxide, the negative electrode material is lithium metal, and the electrolyte is a lithium battery. The main components of the electrolyte are dimethoxyethane, propylene carbonate, and lithium perchlorate. Its shape resembles a button, hence it is referred to as a button lithium battery or lithium manganese button battery.
I recall that the 2019 Nissan X-Trail's key fob typically uses a CR2032 battery, which is a standard coin cell with 3 volts, commonly used in many car remote keys. As an enthusiast who often helps friends with car repairs, I recommend replacing it yourself: first locate the seam on the back cover of the key, gently pry it open with a plastic card—avoid using metal tools to prevent scratches. When removing the old battery, observe the positive and negative terminal positions; usually, the positive side faces up. Clean the contact points before inserting a new CR2032 battery. Reassemble the cover and test the remote functions. Sometimes, re-pairing may be needed after replacement—hold the lock button for a few seconds. A reminder: battery life is generally 2-3 years; delayed or unresponsive buttons are a sign it's time for a replacement. Buying batteries online costs just a few dollars, but choose reputable brands to avoid low-quality products.
I've been driving this X-Trail for five years now, and have replaced the key fob battery twice - confirmed it's a CR2032 model. Once during winter when the remote stopped responding, I went to a hardware store to buy the same battery and replaced it at home. The process was super simple: use a small screwdriver to pry open the back cover, remove the old battery, and insert the new one in the same position. Just be careful not to reverse the polarity during installation - it worked perfectly immediately after replacement. From my experience, CR2032 batteries are easy to find and replace, available at supermarkets and electronics stores. I recommend regular checks, like replacing it every two years to prevent unexpected failures. Also, never replace the battery when the key gets wet - wait until it's completely dry, otherwise short circuits may damage the circuitry. Overall it's hassle-free, a DIY job that takes just minutes.
