What is the battery model for the Tayron remote key?
4 Answers
Tayron key battery model is CR2025. CR2032 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, if it is square, F is used instead; 20 indicates that the battery diameter is 20mm; 25 represents the battery height of 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 140-170mAh. CR2025 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 greatly shortened. Domestic first-tier brand batteries can basically guarantee this lifespan. If the usage environment is ideal (sealed, room temperature, no 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 3 steps: Step 1: Remove the mechanical key. Press the buckle 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 groove and a shallow groove at the top of the smart key. The deep groove is the keyhole, and the shallow groove is used to open the battery cover. Insert the mechanical key into the shallow groove and pry it outward with force to open the battery cover. After opening, you can see the button battery. Gently pry it, and the battery will come out. Step 3: Replace the new battery. Install the new battery, then reattach the battery cover and mechanical key in order, and the key battery replacement is complete.
I've been driving the Volkswagen Tayron for three years and have previously encountered issues with the key battery running out of power. It uses the CR2032 model, which is a very common button cell battery that can be easily purchased at supermarkets or online at an affordable price, just a few yuan each. Replacing it is quite simple: use a small screwdriver or a thin card to gently pry open the back cover of the key. When removing the old battery, be careful not to pull it out forcefully to avoid damaging the contacts. When inserting the new battery, make sure the positive side faces up; otherwise, it may not work. The battery typically lasts about two years, depending on usage frequency. If the key stops working or the buttons become unresponsive, it's likely time to replace the battery. I once mistakenly bought a CR2025, but it was the wrong size and wouldn't fit at all, so it's essential to confirm the correct model. Doing it yourself saves the hassle and unnecessary expense of going to a 4S shop, but be gentle during the process to avoid damaging the internal circuitry of the key.
As someone with some knowledge of automotive accessories, I've discovered that the remote key battery for the Tayron is the CR2032 model. CR stands for lithium-ion battery, and 2032 indicates a diameter of 20mm and a thickness of 3.2mm. This design provides stable current to the key chip at 3V. I've opened my own key and confirmed that the factory-installed battery is indeed this model, typically lasting over two years. The replacement process isn't too difficult: there's a small notch on the back cover, and once pried open, the battery can be removed. When inserting a new CR2032, make sure to align the positive and negative terminals correctly. If the key fails to unlock from a distance, it's often due to battery aging; I recommend keeping a few spares in the car for emergencies. Compared to similar models, most Volkswagen SUVs use the same battery type—for example, the Tiguan also uses CR2032, showing high compatibility. To extend battery life, avoid exposing the key to high temperatures.
I just replaced the battery in my own Tayron key a few days ago, the model is CR2032. You can see this label when you open the battery cover, it's a common button cell type. DIY replacement is very convenient: pry open the back cover, remove the old battery, insert the new battery in the same orientation, and snap the cover back on. The whole process takes about five minutes, no need to visit a professional shop. If the key's red light doesn't illuminate when pressed or the car's unlocking response becomes sluggish, it's usually a battery issue - timely replacement is recommended to avoid affecting daily use. Brands like Nanfu or Sony's CR2032 batteries available on the market are good choices, with a lifespan of about one to two years. Regular checks can prevent unexpected failures.
