Which battery to choose for the Skoda Kodiaq key
In the keys Skoda Kodiaq (including restyled versions 2021+) a standard battery type is used CR2032 with a voltage of 3 V. This is a lithium βtabletβ with a diameter of 20 mm and a thickness of 3.2 mm. However, not all batteries of this type are equally suitable for car keys. Here's what you should pay attention to:
- π Capacity: the best option is batteries with a capacity 220β240 mAh. Cheap analogues (180β200 mAh) will last 1.5β2 times less.
- π·οΈ Brand: recommended manufacturers - Duracell, Energizer, Panasonic or Varta. Chinese no-name batteries often leak and damage the contacts.
- π Expiration date: Check the date on the package. A battery manufactured more than 2 years ago may be partially discharged.
- π‘οΈ Anti-counterfeit protection: Original batteries have holographic stickers or laser engraved logo.
In some keys Kodiaq with function Keyless Entry (keyless entry) battery can be used CR2026 (0.7 mm thinner). To accurately determine the type, look at the old battery - the markings are on its body. If the key is new and the battery has not yet been changed, refer to the data in the table below.
| Year of production Kodiaq | Key type | Recommended battery | Notes |
|---|---|---|---|
| 2017β2020 | Standard (3 buttons) | CR2032 | Suitable for most versions |
| 2021β2026 | Touch (Keyless) | CR2026 or CR2032 | Depends on the configuration (see markings) |
| 2020+ (facelift) | Key with display | CR2032 (high capacity) | Requires a battery with a leakage current of <1 Β΅A |
β οΈ Attention: Do not use batteries markedDL2032orECR2032- These are alkaline analogues that are not intended for long-term use in car keys. They can leak and damage the board.
Tools and preparation for replacement
To replace the battery in the key Skoda Kodiaq You don't need professional equipment, but some tools will make the process much easier. Here is a complete list of what you need to prepare:
- π§ Flat head screwdriver (preferably with a thin tip) or a plastic pick for disassembling the case.

Step-by-step instructions for replacing the battery
Disassembling the key Skoda Kodiaq does not require special skills, but it is important to follow the sequence so as not to damage the case or board. Below is a universal instruction suitable for most versions of keys (including restyled models).
Step 1: Opening the Key Case
Place the key on a flat surface with the buttons facing up. Insert a flathead screwdriver into the slot between the two halves of the case (usually located closest to the key fob ring). Gently twist the screwdriver to release the latches. Do not use excessive force - the plastic may crack.
What to do if the case cannot be disassembled?
If the key does not budge, try slightly heating it with a hairdryer (temperature no higher than 50Β°C) - this will make the plastic more elastic. Alternative method: use two screwdrivers, inserting them into opposite slots and simultaneously pushing the halves apart.
Step 2: Removing the Old Battery
After disassembling the case you will see a board with a battery. Gently pry up the old battery with a screwdriver or your fingernail and remove it. Please note polarity: There is usually a marking on the board + and β. If the battery leaks, clean the contacts with an alcohol wipe.
Step 3: Install a new battery
Insert a new battery plus up (unless otherwise indicated on the board). Make sure it fits snugly into the socket. If the battery is loose, check to see if there is any debris or oxidation left in the groove.
Step 4: Assembling the Key
Align the two halves of the case and squeeze them until the latches click. Check that all buttons can be pressed without jamming. If the case does not close tightly, check that the board is installed correctly - sometimes it moves during assembly.
Before final assembly, press all the key fob buttons one by one to make sure they work correctly. If any button does not work, disassemble the key again and check the position of the board.
Common mistakes and how to avoid them
Even something as simple as replacing a battery can turn into problems if you make mistakes. Here are the most common ones and how to prevent them:
- π Reversed polarity: If you install the battery with the minus side up, the key will not work. There is always a marking on the board

- πΆ Lack of synchronization: after replacing the battery in the keys with Keyless resynchronization may be required. Instructions are given above.
- π Wrong battery type: installing CR2026 instead of CR2032 (or vice versa) will lead to unstable operation of the key fob.
Critical error: if after replacing the battery the key stops working at all, check to see if the immobilizer chip has moved. In some key models Kodiaq it is attached with double-sided tape and can fall off if disassembled carelessly.
