Owners Skoda Kodiaq sooner or later they are faced with the need to replace the battery in their lighter key. The symptoms of a low battery are familiar to many: the key fob stops opening the car the first time, the signal weakens, and a warning appears on the dashboard Key battery low. In this article we will analyze all the nuances of the procedure - from choosing the right battery to step-by-step analysis of the key body of different generations Kodiaq (including restyled 2021+ models).
Key design Ε koda unified for most models of the group VW, but Kodiaq has its own characteristics: for example, in keys with a function Keyless Entry uses a different type of battery than standard key fobs. We will go into detail about the differences between the keys 2017-2020 and 2021-2026 years, and also give recommendations on choosing batteries to avoid counterfeits and premature discharge.
Types of Skoda Kodiaq keys and their features
Factory Ε koda Auto completes Kodiaq two main types of keys that are visually similar but have different internal components:
- π Standard key (without
Keyless) - equipped with lock/unlock buttons and a mechanical blade. Uses battery typeCR2032(3B). - π Key with Keyless Entry - supports contactless access and push-button engine start
Start/Stop. Requires a batteryCR2026(3B) due to the compact board with an additional chip.
It's easy to distinguish them: keys with Keyless have an inscription on the back cover KEYLESS or a car icon with waves. They are also slightly thicker than standard ones. Carefully check the type of key before purchasing a battery - installation CR2032 instead of CR2026 may damage the contacts!
| Characteristics | Standard key | Key with Keyless Entry |
|---|---|---|
| Battery type | CR2032 |
CR2026 |
| Capacity, mAh | 220-240 | 160-170 |
| Service life | 2-3 years | 1.5-2 years |
| Replacement features | Simple disassembly, without the risk of damaging the antenna | Requires care when removing the board |
Keys Kodiaq The restyled version (from 2021) received an updated body design, but the internal structure remained the same. The only change is that the latches on the back cover are more rigid, which makes disassembly more difficult without a special tool.

Which battery to choose: review of brands and types
Not only its service life, but also the stability of the immobilizer depends on the quality of the battery. Cheap batteries often lose capacity at low temperatures, which leads to malfunctions of the key in winter. Recommended brands:
- π Duracell β optimal price/quality ratio, stable operation at β20Β°C.
- π Energizer β increased service life (up to 5 years in storage mode).
- π Panasonic - the best choice for keys with
Keylessthanks to low self-discharge. - π Varta - a budget option, but with a risk of counterfeiting (check the hologram on the packaging).
Avoid batteries that are not marked or have the type "Super Heavy Duty" - These are cheap analogues with reduced capacity. For Kodiaq with Keyless Entry It is critical to use batteries with markings "Premium" or "Long Life", since they provide a stable voltage of 3V throughout their entire service life.
Before purchasing, check the production date on the packaging. Batteries older than 2 years lose up to 20% of their capacity even in the original packaging.
The price of a high-quality battery varies from 80 to 200 rubles. Savings of 20-30 rubles may result in the need for replacement in 6 months instead of 2 years. The table below compares popular models:
| Brand | Model | Average price, rubles | Features |
|---|---|---|---|
| Duracell | CR2032 DL2032 | 180 | Resistance to temperature changes |
| Energizer | CR2026 ECR2026 | 150 | Increased capacity (170 mAh) |
| Panasonic | CR2032 BR2032 | 200 | Minimum self-discharge (0.5% per year) |
| GP | CR2032 3V | 60 | Budget option, short service life |
Step-by-step instructions for replacing the battery
The replacement process takes no more than 5 minutes, but requires care. You will need:
- π§ Flathead screwdriver (or plastic pick)
- π New battery (check type!)
- π§² Magnet (for fixing the key blade during disassembly)
Step 1: Removing the Mechanical Key
Press the button at the bottom of the key fob and pull out the metal blade. This will prevent accidental damage to the locking mechanism during disassembly.
Step 2: Disassembling the case
Insert a screwdriver into the groove on the back cover (logo side Ε koda) and carefully pry it off. The lid is held on by two plastic latches - do not use excessive force to avoid breaking them. In the keys 2021+ The latches are reinforced so a little more pressure may be required.
Check the key type (Keyless or standard)
Buy a battery from a trusted brand
Prepare a screwdriver and magnet
Take a photo of the board location (in case of an assembly error) -->
Step 3: Removing the Old Battery
Pry off the battery with a screwdriver or your fingernail. In the keys with Keyless the board can be secured with an additional fastener - do not pull it by force, but first release the latch.
Step 4: Install a new battery
Insert a new battery plus up (there is a marking on the board +). Make sure the contacts are not dirty - wipe them with an alcohol wipe if necessary.
Step 5: Assembling the Key
Close the back cover until it clicks. Check the operation of all buttons and proximity access (for Keyless). If the key does not work, disassemble it again and check the polarity of the battery.
What should I do if the key does not work after replacement?
1. Check the polarity of the battery (plus should be on top).
2. Make sure the pins on the board are not bent or oxidized.
3. Try to βresetβ the key by pressing all buttons simultaneously for 5 seconds.
4. If the problem remains, the antenna inside the case may be damaged (diagnostics at a service center is required).
Common mistakes and how to avoid them
Even in such a simple procedure, the owners Kodiaq make mistakes that can damage the key. Let's look at the most common ones:
β οΈ Attention: Never use metal objects (knives, scissors) to disassemble the key. The plastic latches are fragile, and scratches on the case will allow moisture to get inside.
- β Wrong polarity - if you mix it up
+andβ, the key will not work and the battery may leak. - β Antenna damage - in the keys with
Keylessa thin antenna loop is located around the perimeter of the board. Its breakage will lead to loss of connection with the car. - β Using expired batteries β even new batteries lose capacity after 3-5 years of storage.
Another typical problem is incomplete closing of the lid. If the latches do not lock, the key may fall apart in your pocket. Check this by lightly pulling the cover after assembly.
Owners Kodiaq 2021 and newer cars sometimes encounter the problem that after replacing the battery, the key stops opening the trunk. This is due to the updated immobilizer firmware. Solution:
- Get into the car and close all doors.
- Insert the key into the ignition (even if you have
Keyless). - Turn the ignition on for 5 seconds, then turn it off.
- Remove the key and check all functions.
How to extend the life of your key battery
Average key battery life Kodiaq - 1.5-3 years, but it can be increased by following simple recommendations:
- π Keep the key away from metal objects - they create parasitic currents that discharge the battery.
- π‘οΈ Avoid extreme temperatures β do not leave the key in the sun or near heaters.
- π± Don't carry your key in the same pocket as your phone. β NFC modules of smartphones can activate the chip
Keyless, shortening battery life. - π Use the key regularly β prolonged inactivity (more than 6 months) leads to self-discharge.
For keys with Keyless Entry critical disable function, if you leave the car for a long time. For example, at airports or in long-term parking. You can do this through the menu Settings β Center lock β Keyless on display MIB3.
Using batteries with high capacity (for example, CR2032H from Panasonic) can extend the replacement interval to 4 years, but only under proper storage conditions.
If you rarely use the car, remove the battery from the key when not in use. This is especially true for owners Kodiaqwho store the car in winter parking.
