Types of ŠKODA Superb keys and their features
Cars ŠKODA Superb third generation (index 3V) are provided with three main types of keys. The type depends not only on the process of replacing the battery, but also on the choice of the power cell.
- 🔑 Retractable blade lighter key - Classic version for basic configurations. The battery is hidden under the back cover, access to it requires care due to fragile latches.
- 📱 A key fob with buttons and a folding key - The most common type. It has two buttons (open/close) and a hidden metal key for mechanical locking.
- 🚗 Keyless-keychain (keyless access) - for versions with the system KESSY. It has an enlarged body and a special antenna for communication with the car.
Models after the facelift of 2019 may have an updated keychain design, but the design remains identical. Logo keys ŠKODA on the front (instead of the VW) use batteries of the type CR2032 year-to-year.

Which battery to choose: types and analogues
For all keys ŠKODA Superb (except for early versions prior to 2015) a lithium battery type is used. CR2032 with tension 3V. However, there are cheap analogues on the market that can reduce the life of the keychain.
| Battery type | Capacity (mAh) | Manufacturer | Service life (approx.) | Price (RUB) |
|---|---|---|---|---|
CR2032 (original) |
220–240 | Panasonic, Duracell, Energizer | 3–5 years | 80–150 |
CR2032 (budget) |
180–200 | GP, Varta, Camelion | 1–2 years | 30–60 |
DL2032 |
220 | Analogue CR2032 from Duracell |
3–4 years | 100–130 |
BR2032 |
190 | For extreme temperatures | 2–3 years | 120–180 |
⚠️ Attention: Labeled batteries LR (for example, LR2032) alkaline, not lithium. They have less stress (there is less stress).1.5V) and don't fit for keys ŠKODA. Their installation will lead to unstable operation of the keychain or complete loss of communication with the car.
For keys with system Keyless It is recommended to use batteries with high capacity (for example, Panasonic CR2032P) as they consume more charge due to constant signal exchange with the machine.
Before buying, check the date of production on the battery pack. Lithium cells lose up to 20% of their capacity in 5 years of storage in a warehouse.
Step-by-step instructions: replacing the battery in the lighter key
