Which battery to choose for the Skoda Rapid 2019 key
In original keys Skoda Rapid 2019 uses a lithium battery type CR2032 3V voltage. However, not all elements of this type will work. The thing is, the keychains VW Group (which includes Skoda) batteries with a high frequency of drowned-in This protects against short circuits in case of accidental contact with metal objects in your pocket.
Recommended options:
| Manufacturer | Battery model | Average price (RUB) | Features |
|---|---|---|---|
| Varta | CR2032 V3032 | 80-120 | Drown contacts, long service life |
| Duracell | DL2032 | 100-150 | High capacity, suitable for keys with illumination |
| Maxell | CR2032 | 60-90 | Budget option, standard contacts |
| Renata | CR2032H | 130-180 | Premium segment, increased resource |
β οΈ Attention: Do not use batteries marked BR2032 They have a smaller capacity and are designed for other operating conditions. Also avoid cheap no-name options: they often flow, which leads to oxidation of contacts inside the key.
Before buying, check the date of production on the packaging. Lithium cells lose up to 20% of their charge over 5 years of storage. The optimal age of the battery is no more than 1-2 years from the date of release.
If the key is equipped with button highlighting (option) Keyless EntryChoose batteries with high capacity, for example, Duracell DL2032 or Energizer CR2032. They hold the charge longer with frequent LED inclusions.
Battery replacement tools
To disassemble the key Skoda Rapid 2019 will not require complex equipment, but there are a few required items:
- π§ Plastic spatula or pick (for separating the body halves)
- π© Phillips screwdriver
PH00(for some key versions) - 𧲠Small magnet (so as not to lose the contact spring)
- πΈ Smartphone (for photographing the location of parts)
- 𧴠Alcohol wipes (for cleaning contacts)
β οΈ Attention: Do not use metal screwdrivers or knives for disassembly! The key body is made of brittle plastic ABS, which breaks easily under rough influence. If you don't have a plastic spatula on hand, you can use an old bank card.
For models with Keyless Go (keyless entry) you will also need:
- π§ Torx screwdriver
T5(for unscrewing hidden screws) - π Tweezers (for removing small antenna parts)
Before starting work necessarily remove the metal ring with the logo from the key Skoda - it interferes with disassembly and can scratch the plastic. The ring is attached to a small pin; it can be carefully pryed off with a fingernail or a plastic spatula.
Step-by-step instructions for replacing the battery
Let's look at the process using a standard key as an example Skoda Rapid 2019 without function Keyless Go. The whole process will take no more than 10 minutes.
Step 1: Separating the Case
Place the key on a flat surface with the buttons facing down. Insert a plastic spatula into the gap between the top and bottom halves of the housing (on the side opposite the metal ring). Gently move the spatula along the seam until you hear a click, indicating that the first latch has opened. Repeat on the other side.
Step 2: Removing the Board
After disconnecting the case, you will see a printed circuit board with a battery. Carefully pry up the battery with a plastic spatula and remove it. Please note polarity: There is usually a marking on the board + and β. If there is no marking, remember which side the old battery was installed in.
Step 3: Install a new battery
Insert the new battery, observing the polarity. Make sure the battery is seated all the way in the slot - sometimes it can get stuck due to dust. After installation, lightly press the battery to check for good contact.
Step 4. Assembling the key
Align the halves of the housing and squeeze them until you hear a characteristic click. Make sure that all the latches are locked - to do this, slightly pull the halves in different directions. If you feel any play, disassemble the key and check whether the board is seated correctly.
βοΈ Check before assembly
β οΈ Attention: If the key does not work after replacing the battery, check whether the synchronization with the immobilizer has been lost. To do this, insert the key into the ignition and turn it to position ON (without starting the engine). Wait 10 seconds - the system should automatically resync.
What to do if the key doesn't sync?
If after replacing the battery and rebooting the system the key still does not work, try the following:
1. Remove the key from the ignition switch.
2. Press and hold the button LOCK on the key fob for 5 seconds.
3. Insert the key back into the lock and turn to position ON.
4. Repeat the procedure 2-3 times.
If this does not help, contact service - the key may need to be re-flashed.
Features of replacing keys with Keyless Go
Keys with system Keyless Entry (keyless entry) have a more complex design. In them, in addition to the standard battery CR2032, an additional antenna is installed for communication with the car at a distance of up to 1.5 meters. When disassembling such keys, you need to consider several points:
1. Additional screws
There may be hidden Torx screws in the case T5. They are located under rubber plugs or stickers. Carefully pry off the plugs with a plastic spatula to avoid damage.
2. Antenna module
Inside the key you will find a thin wire connecting the board to the antenna. Do not pull on it - this may cause it to break. If the antenna comes away from the contacts, carefully insert it back using tweezers.
3. Check after assembly
After replacing the battery, check the operation Keyless Go:
- Approach the car with the key in your pocket - the doors should unlock automatically.
- Touch the door handle with the button LOCK β the car should be closed.
- Try starting the engine with the button START/STOP (if any).
If the keyless entry does not work, but the mechanical key entry works, the problem may be with the antenna. In this case, diagnostics in the service is required.
Common mistakes and how to avoid them
Even with the apparent simplicity of the procedure, many owners Skoda Rapid make mistakes that lead to key breakage or immobilizer malfunction. Let's look at the most common ones:
1. Using the wrong batteries
Installing batteries with the wrong polarity or the wrong type (BR2032 instead of CR2032) can lead to short circuit and failure of the key board. Always check the labeling!
2. Rough disassembly of the case
The use of metal tools often results in chipped plastic or damaged latches. If the case is cracked, it can be glued with superglue Loctite 406, but this is a temporary solution - over time the key will fall apart.
3. Dirt getting on the contacts
Dust or fabric fibers on the board may cause false positives buttons or complete inoperability of the key. Before assembly, wipe the contacts with an alcohol wipe.
4. Loss of contact spring
Some keys have a small spring under the battery to ensure reliable contact. If it falls out, the key will not work. As a replacement, you can use a spring from a ballpoint pen, cutting it to the desired size.
5. Incorrect synchronization
After replacing the battery, some owners forget to resync the key with the car. This leads to the fact that the car does not respond to signals from the key fob, although the battery is new. The solution is the procedure for βlearningβ the key through the ignition switch (described above).
If after replacing the battery the key stops working completely (even mechanical opening does not help), do not try to βreanimateβ it yourself. In 90% of cases, this indicates a damaged immobilizer chip and requires reprogramming at the dealership.
How to extend battery life
Average battery life CR2032 in the key Skoda Rapid - 2-3 years. However, with proper use, this period can be increased to 4-5 years. Here are some practical tips:
1. Keep the key in a dry place
Humidity accelerates contact corrosion and increases battery self-discharge. Do not leave the key in the bathroom, in the kitchen near the stove, or in the pocket of wet clothes.
2. Avoid extreme temperatures
Lithium cells do not tolerate both overheating and extreme cold. Do not place the key on the dashboard in direct sunlight or near heaters. The optimal storage temperature is from +10Β°C up to +25Β°C.
3. Do not carry the key with metal objects
Contact with coins, a key ring, or a smartphone may cause parasitic discharges, shortening battery life. Use a case or a separate pocket for the key.
4. Turn off the button backlight (if any)
In keys with option Keyless Entry The button backlight turns on when pressed and consumes additional energy. If you rarely use this function, you can disable it through the car settings menu (section Central Locking β Key Settings).
5. Check voltage regularly
Using a multimeter, you can measure the battery voltage without disassembling the key. Normal value - 3.0β3.3 V. If the voltage drops below 2.7 V, it's time to change the battery.
β οΈ Attention: If you rarely use the car (for example, in winter), remove the battery from the key when not in use. Lithium cells are discharged even without load, and a long period of inactivity with a dead battery can lead to loss of synchronization with the immobilizer.
