Main features:

• 🔋 Weak indicator signal: When pressing buttons, the light on the key fob blinks dimly or does not light up at all.
• 🚗 Reduced range: the key only works in the immediate vicinity of the car (less than 1–2 meters).
• ⚠️ Intermittent operation: The central locking does not open/close the first time or requires multiple presses.
• 🔑 Message on the dashboard: on some versions Kodiaq (with MIB3) a warning may appear "Key battery low".

If you experience any of these symptoms, do not delay replacement. Complete discharge of the battery may result in loss of key synchronization with the immobilizer, which will require reprogramming from an authorized dealer.

⚠️ Attention: If the key stops working completely (does not respond to buttons, the indicator does not light), do not try to disassemble it without preparation. In some cases, this may not be due to the battery, but to damage to the board or antenna. It is better to first check the battery in another device (for example, a watch or remote control).

Which battery to buy for the ŠKODA Kodiaq key

Recommendations for selection:

• 🔋 Give preference to brands with low self-discharge: Duracell or Energizer last 20–30% longer than cheap analogues.
• 🛒 Buy from trusted places: Avoid market stalls, where there is a high probability of encountering a fake.
• 📅 Look at the production date: Battery, Released more than 2 years ago, may already be partially discharged.
