The main thing is to know exact battery type (it depends on the year of manufacture and configuration), have suitable tools on hand and follow the instructions so as not to damage the case or electronic board. In this article we will analyze the replacement process step by step, talk about the nuances for different versions of key fobs (including backlit keys and keyless entry Keyless), and also give tips on how to extend the life of a new battery.

Which battery to buy for the Škoda Kodiaq key fob

The type of battery depends on the generation of the car and the type of key fob. In most cases for Kodiaq (2017–2026) in use lithium batteries type CR2032 (3 V, 220 mAh), but there are exceptions:

• 🔋 CR2032 — standard for key fobs without illumination (article number of the original battery from Škoda: N 910 891 01).
• 🔋 CR2026 — found in keys with backlit buttons (thickness 2.5 mm versus 3.2 mm for CR2032).
• 🔋 CR1632 - rare, but installed in key fobs with the function Keyless (keyless entry).

To accurately determine the type, remove the old battery and look at the markings on its case. If the key fob is being disassembled for the first time, refer to the table below. Buy batteries trusted brands: Duracell, Energizer, Panasonic or Varta. Cheap analogues can leak and damage the electronic board.

1. Place the keychain on a flat surface buttons down. The mechanical key (if built-in) must be removed.

2. Insert a flathead screwdriver or pick into gap between body halves on the side where there are no buttons (usually a clip is located there).

3. Gently twist the tool to release the latches. It will start from the mechanical key side.

4. When the housing opens slightly, do the same on the opposite side. Don't delay force the halves - they should separate easily.

If the key fob does not budge, check to see if there is a mechanical key left inside - it may block disassembly. In backlit keys, you will first have to remove the LED module (it is attached to two small latches).

When the case is disassembled, you will see a circuit board with a chip and a battery socket. In most cases, the battery is held on a plastic clip or metal retainer. Remove the old battery by prying it off with a screwdriver or magnet, and install a new one, observing polarity (plus should look up).

Features for different versions of key fobs:

• 🔑 Standard key fob (without backlight): battery CR2032 Installs into the socket without additional fasteners. After replacement, check if the contacts are bent.
• 💡 With backlit buttons: before replacing the battery CR2026 disconnect the LED module (it is attached to two wires). Do not pull on the wires - they are fragile!
• 📶 Keyless (keyless access): the battery can be soldered to the board. In this case, you will need a soldering iron or contact service.

What should I do if the key fob does not work after replacement?

If the key fob does not respond to button presses, check:

1. Correct installation of the battery (polarity!).

2. The integrity of the contacts on the board (are they bent?).

3. Presence of oxidation - clean contacts with alcohol.

If the problem persists, the immobilizer settings may have gone wrong. In this case, reprogramming will be required at the dealership (cost ~1,500–3,000 rubles).

Assembling the key fob and checking its functionality

When the battery is installed, all that remains is to assemble the key fob in reverse order. Make sure that:

• 🔄 All body latches tightly fixed (no play).

Why does the key fob only work near the car, even though the battery is new?

The reason may be discharged (voltage below 11.8 V), synchronization failure or failure of the immobilizer antenna. Try reprogramming the key fob (instruction above) or checking the battery voltage.

What should I do if, after replacing the battery, the key fob does not sync with the car?

Perform the retraining procedure:

1. Close all doors.
2. Put the key in the ignition lock and turn to the "ON" position.
3. Press and hold the button LOCK on the key fob for 5 seconds.
4. Repeat step 3 2 more times.
