What is the battery model for the Tiida key?
3 Answers
The battery model for the Tiida key is CR2025. CR2032 is a lithium manganese dioxide battery, named according to the IEC standard. 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, with F used for square shapes; 20 indicates the battery diameter is 20mm; 25 represents the battery height is 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 standards are 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 to 8 years or even 10 years. Generally, replacing a car key battery involves 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 will 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 open to reveal the coin battery. Gently remove the battery. Step 3: Replace the new battery. Install the new battery, then reattach the battery cover and mechanical key in order to complete the battery replacement.
I used to be a car mechanic and have worked with many car models. The battery for the Tiida key is usually the CR2032 model, which is widely used and as reliable as a universal part. Why do I say that? Because this battery is small and cheap, easily available in supermarkets or online, and costs just five yuan to replace. Changing it is simple too—just use a screwdriver to pry open the key shell, pop out the old battery, and insert the new one, making sure to align the positive and negative terminals correctly (don’t reverse them!). It’s recommended to check it every two years; otherwise, if it runs out of power, you won’t be able to start the car, which would be a hassle. Additionally, some older Tiida models might use CR2016, but CR2032 has strong compatibility, so it’s always good to have one on hand. In short, keep an eye on the key’s indicator light—replace it when it dims to save money and stay worry-free.
I've been driving my Tiida for several years, and it was really embarrassing when the key suddenly stopped working. Later, I realized the battery was dead and had to frantically check the model number. After confirming it was a CR2032, I bought one at a convenience store, opened the key casing, and fixed it in no time. Looking back now, the battery life is about two years, depending on how often you use the car—frequent unlocking drains it faster. It's best to buy original or well-known brands to avoid leakage from cheap ones damaging the key. I usually keep a spare in the glove box for emergencies. Some people mistakenly think it's a CR2025, but it's thicker and doesn't fit the Tiida's slot. Knowing this small detail can save you a trip to the dealership and hundreds in repair costs.
