This article contains detailed instructions with photos, battery selection, common mistakes and answers to frequently asked questions.

What kind of battery is in the ŠKODA Superb 2 key?

In the original key ŠKODA Superb II (article 3T0 959 753 B or 3T0 959 753 C) uses a lithium battery type CR2032 with a voltage of 3 V. This is a standard battery with a diameter of 20 mm and a thickness of 3.2 mm, but not all analogues are suitable due to the characteristics of the contact group.

Official battery requirements:

• 🔋 Type: CR2032 (not to be confused with CR2026 or CR2016 - they are thinner and will not provide reliable contact!).
• 🏷️ Brand: recommended Duracell, Energizer, Panasonic or Varta (cheap no-name batteries run out quickly).
• ⚡ Capacity: at least 220 mAh (the original ŠKODA battery has 240 mAh).
• 🛡️ Protection: Leak-proof elements ("Leak-Proof" marking) are preferred.

The cost of an original battery from a dealer is from 300 rubles, but suitable analogues can be bought at any hardware store or ordered at Wildberries/Ozon for 50–150 rubles. The main thing is to avoid counterfeits: check the packaging for the presence of a hologram and the production date (the shelf life of lithium batteries is 5–7 years).

Tools and preparation for replacement

To replace the battery in the key Superb 2 you will need:

• 🔧 A flat-head screwdriver with a thin blade (or a plastic pick).
• 🔋 New battery CR2032.
• 🧲 Small magnet (optional, to secure the screw during disassembly).
• 📸 Smartphone (to photograph the location of the board before disassembling).

Before starting work:

1. Make sure you have spare key - in case something goes wrong.
2. Check the operation of all key fob buttons (perhaps the problem is not in the battery, but in the contacts).
3. Prepare a clean work area - a lost screw or spring can result in costly repairs.

⚠️ Attention: Do not use metal objects with sharp edges (knives, blades) - they can scratch the key body or damage the board. If you are afraid of damaging the latch, buy a special plastic tool for disassembling key fobs (costs ~200 rubles per AliExpress).

Step-by-step instructions: how to disassemble the key and replace the battery

1. Step 1: Removing the metal key.
   

   Press the unlock button (usually located on the side) and remove the mechanical key from the case. This will make the latch easier to access.

2. Step 2: Dividing the body.
   

   Insert a flat-head screwdriver into the gap between the halves of the case (from the side of the key ring) and carefully move them apart, moving around the perimeter. The latch is located closer to the trunk release button - you will have to apply a little more effort there.

3. Step 3: Removing the board.
   

   After separating the case, remove the board with the battery. It is attached to a small screw (sometimes there is none - the board is simply inserted into the grooves). Don't pull the wires!

   Use a screwdriver to pry up the old battery and remove it. Install the new one, observing the polarity (the plus must be on top!). Press the battery until it clicks.

5. Step 5. Assembly.
   

   Place the board back, align the case halves and press them together until the latch clicks. Insert the metal key into place.

• 🔄 Battery polarity (reverse it).
• 🔌 Contacts on the board (they may have oxidized - clean with alcohol).
• 📶 Antenna location (it should fit tightly to the body).

What to do if the key cannot be disassembled?

If the case does not give in, try heating it with a hairdryer (temperature 50–60°C) - the plastic will become softer. Do not use force: in 90% of cases the problem is an unopened latch. Watch a video disassembly for your key model on YouTube (search for "ŠKODA Superb 2 key battery replacement").

Frequently asked questions about replacing the battery in the ŠKODA Superb 2 key

❓ Can I use a rechargeable battery instead of a CR2032?

No, this is not recommended. Rechargeable batteries (eg ML2032) have a lower voltage (2.4 V instead of 3 V), which leads to unstable operation of the key. In addition, they discharge faster and may leak when overcharged.

From official dealers ŠKODA the cost of replacing the battery in the key ranges from 800 to 1,500 rubles (depending on the region). At the same time, the battery itself will cost you 300–500 rubles, and the rest is work. Self-replacement saves up to 80% of money.

❓ Why does the key only work near the car, even after replacing the battery?

There may be several reasons:

• 📡 Bad antenna contact: check if it is pinched when assembling the key.
• 🔋 Defective battery: try replacing it with another one (even new elements are sometimes discharged).
• 🚗 Problems with the signal receiver in the car: Diagnostics of the comfort unit is required.

❓ Is it possible to replace the battery in a Keyless Go key?
