Replacing the battery in the key Rapid - a simple procedure that takes 5-10 minutes, but has its own nuances. In this article, we will look at how to open the case correctly, what type of battery is needed for different years of manufacture, and what to do if the key does not work after replacement.

For example, models before 2017 often use a battery CR2032, and in newer ones - CR2026. The wrong choice of battery will lead to rapid discharge or even damage to the contacts.

Which battery is needed for the Skoda Rapid key: CR2032 or CR2026?
The type of battery depends on the year of manufacture and the type of key you have. Rapid. In most cases, one of two options is used:
| Year of issue | Key type | Recommended battery | Alternative options |
|---|---|---|---|
| 2012β2016 | Standard key fob (2 buttons) | CR2032 (3V, 220 mAh) | CR2026 (smaller capacity) |
| 2017β2021 | Key fob with 3 buttons (including trunk) | CR2026 (3V, 160 mAh) | CR2032 (may not fit) |
| 2022βpresent | Key with contactless start (Keyless) | CR2032 (original only) | Analogues are not recommended |
Why is it important to choose the right type? Battery CR2032 thicker (3.2 mm) and has a larger capacity than CR2026 (2.5 mm). If you put a thicker battery in a key designed for CR2026, the case may not close, and the contacts may become deformed. The reverse situation (installation CR2026 instead of CR2032) will lead to poor contact and rapid discharge.
Advice: buy batteries from trusted brands - Duracell, Energizer, Panasonic or Varta. Cheap analogues are often counterfeited, and their actual capacity may be lower than declared.
