The situation when the key fob to start the car refuses to work is familiar to all car enthusiasts. Because of this little thing, a broken miniature source of electricity, the car owner has to waste his nerves and time. Not all drivers know how to properly replace the battery in a Skoda Octavia A7 key.
In our article we will look at the procedure for opening the key without damage, and we will tell you how to replace the battery in the Skoda Octavia A7 key. The reader will also learn other useful information on the topic: how to get into the Skoda Octavia A7 with a broken battery.
What kind of battery is in the key?
On the conveyor, a CR2025 3V battery from Panasonic is installed into the Octavia A7 key fob. On average, such a battery lasts up to three years, but sooner or later it has to be changed, as evidenced by this inscription on the dashboard.
Recommendation appearing on the dashboard
It is not always possible to find a “native” battery, and then the question arises of what alternative option is available. Their list is quite large:
| Name | Type | Approximate cost (RUB) |
| Energizer | CR2025 | from 100 |
| Panasonic Power Cells | CR2025 | from 100 |
| Duracell | CR2025 | from 180 |
| Renata | CR2025 | from 100 |
| Sony | CR2025-5BL | from 30 |
| Camelion | CR2025 | from 30 |
| VARTA | CR2025 | from 100 |
Any of the listed batteries will fit into the key fob, but their service life is directly dependent on the cost. To be fair, let’s say that even a branded expensive battery can hide a fake. Here we can only hope for the integrity of the sellers and luck.
Disassembly and replacement
The battery in the Skoda Octavia A7 key is replaced using a flat screwdriver if a new battery is available. To avoid damage to the key fob, we will tell you in detail how this is done.
We bring the key into working condition.
Key with folded blade
Insert a flat-head screwdriver into the opened opening.
Screwdriver in the “body” of the key fob
Without making much effort, without undue haste, we turn the tip of the screwdriver around the axis.
Screwdriver movement
The top cover disengages with a characteristic click, after which there is no need for a screwdriver, since the remaining actions are performed by hand.
Removing the cover
The space for installing the battery opens.
Battery location
Insert a screwdriver with a narrow pin into the recess specially made for this purpose and remove the used battery.
Removing the battery
That's all, now all that remains is to replace it with a new, expired battery and reassemble it in reverse order.
Opening a car with a mechanical key
If it is not possible to buy a new battery, you can open the car with a mechanical key.
You need to do the following:
- Release the keyhole of the keyhole covered by the cap. To do this, press the door handle towards you, pry it off with a screwdriver or wrench, then remove the cover.
- Insert the key into the unlocked lock and turn it. This procedure must be carried out carefully, because the mechanism itself, which has been inactive for a long time, could oxidize, rust and lose its functionality. For preventive purposes, it is recommended to spray it with the tested product VD-40, then wait until the aerosol touches the metal for five minutes.
- After the driver enters the cab, you can start the car.
The process of replacing the battery in the Skoda Octavia A7 key
How to open and start a car if the battery is dead
Even replacing the battery on the Skoda Octavia A7 key fob sometimes does not allow you to easily open the car door and start the engine. In this case, the door can be opened using a physical key. To do this, you need to release the keyhole, which is hidden by a plastic cover in the handle on the driver's door.
Plastic cover that hides the lock
To remove the plastic cover, you need to pull the handle towards you and place a screwdriver or, if one is not at hand, a key under it.
Removing the lining from engagement
Using the selected tool as a lever, we disengage the lining. The released cover can be removed by hand without difficulty.
Removing the trim
Access to the castle is now open.
Lock
We insert the key into it.
Insert the key
If you rarely use this method of opening doors, then there is no need to rush to immediately make a full turn. If the lock was not in working order, the locks could oxidize or rust. Therefore, it is first recommended to inject WD-40 into the inside and wait about 10 minutes. Then slowly make movements in different directions. And only after feeling freedom of movement can you make a full turn.
Expert opinion Alexey Bartosh Specialist in repair and maintenance of electrical equipment and industrial electronics. However, even opening the door with a low battery will only result in receiving a notification from the on-board system that it could not find the key. Consequently, a car that does not have an ignition switch cannot be started without changing the battery in the key fob. But even after installing a new battery, it is not always possible to achieve interaction between the key fob and the vehicle systems.
Then we perform synchronization. The algorithm for this operation for the first key is as follows:
- Turn off/on the ignition. All further actions must be completed within thirty seconds, otherwise you will have to start all over again.
- Close the driver's door and mechanically lock the lock using the second key.
- If the first copy is being programmed, then press unlock once.
- After six seconds, press unlock again. After opening the lock, the system will send a signal confirming the entry to the first position.
To synchronize the second key, repeat the first two steps, and then press unlock 2 times. After 5 seconds, press again. As a result, the lock on the door will open and a sound signal will sound, confirming that the key has been written to the second position.

How to disassemble a Skoda Octavia key and change the battery
Many people have at some point encountered the problem of a dead battery in the alarm remote control or key. Such a problem can happen to any person, so you need to know how to open the car in similar situations and how to replace the battery . Within the framework of this article, this information will be presented using the example of a Skoda .
Sequence of work
You need to prepare a new battery and a small flathead screwdriver. You need a lithium battery, which has the number CR2025, with a power of 3 V.
- We throw away the sting.
- Insert a screwdriver into the side recess and carefully lift the cover up.
- Turn the screwdriver against its axis and remove the upper part of the housing.
- We insert a screwdriver into a special slot near the battery and slightly pry it, it should pop out.
- We replace the old power source with a new one.
- Align the top cover around the perimeter and snap it into place.
This is how the battery in the Octavia A7 key is replaced. In a similar way, you can change the battery in the device for the Octavia A5. Now you can remove the car from the alarm and start it calmly.
Before the battery in the key fob is completely discharged, a message will appear on the car display indicating that it is time to change the key fob battery. This inscription appears for a very short time, so there is a high probability that the key fob will stop working unexpectedly.
Therefore, car enthusiasts will find it useful to know how to get into the car when the key does not work or is lost.
Characteristics of the CR2025 battery
This battery has a round shape. Its body is marked with the following symbols:
- C is a lithium battery;
- R – radial shape;
- the first indicator 20 indicates the diameter of the product in mm;
- another parameter 25 indicates its height: 2.5 mm.
Battery capacity: 165 mAh, operating voltage: 3 V. When it is discharged, it drops to 2 V.
CR2025 battery
We disassemble the key and change the battery
So, to replace the battery in the key, you will first need to buy and prepare a new battery. A CR-2032 lithium battery is used for this. You also need to prepare a small screwdriver for this work:
- The first thing you need to do before replacing is to remove the key.
- After that, in the place where the key itself is hidden, you need to lift the latch with a screwdriver. Next, carefully pull the lid up.
- You need to insert the same screwdriver into the resulting gap and carefully not turn it too much.
- After this, you can remove the protective cover with your hands, where the desired element will be located.
- In this disassembled form, it is possible to replace the battery with a new one and then perform the operation in the reverse order.
Here is a simple procedure for disassembling the key and changing the battery. This method is suitable for Skoda Octavia A5 and A7. After this, access to the car will be unlocked. But it’s not always possible to get by with just changing the battery. For some reason, the key may not work, and even worse if it is lost, but you need access to the car. Therefore, it is necessary to know methods of how to enter the salon without a key.
Important addition
But it also happens that there is nothing to replace the battery with, but you have to go. The fact that the old battery is completely discharged is indicated by an LED indicator that does not respond to key presses on the remote control. In this case, we do not get angry, but act as follows. We approach the car, release the mechanical key from the device and carefully open the driver's door. At this stage, the included standard alarm is activated. After turning it off, you can start starting the engine. But this is not so easy to do: the start-stop button does not work, and the smart key is not detected by the on-board computer. But all is not lost, because... Especially for these cases, Korean engineers came up with a clever system. We lift the armrest between the driver and passenger seats, and a niche opens in front of us, at the bottom of which a secret is hidden in the form of a recess for a smart key. Insert the bottom side there until it stops and secure.
After this, let's try to restart the machine. This time everything should work - the system will react and come to life, and the engine will start. Now you can safely drive to the place where you can buy a new battery. First, we remove the smart key from the slot into which we inserted it earlier. While the central locking is not activated, the interior can be locked and unlocked with a mechanical key.
This correct method has repeatedly helped car owners in seemingly hopeless situations. This is good because it does not require a lot of time and effort to implement, and also does not require entering codes, passwords, numbers, otherwise it will greatly complicate the task, although it will increase the level of vehicle security.
This example shows us how a harmless (if ignored) organizational nuance can turn into a rather serious technical problem. Therefore, always keep a spare battery (or rather, more than one) in the glove compartment, just in case.
Replacing the battery in the factory key for Skoda Octavia A7
Battery marking
: CR 2025.
- If the car slams shut, the keys remain in the middle, and the engine, as it is also called, is running, then it is recommended to try pressing the door and pushing a wire into the gap that appears. Using a similar wire, you can reach the window lift button and press on the lowering positions. Later it is possible to get into the salon to the key.
- If it so happens that there is no key, then the lifts will not work. In this case, you will need to turn to special specialists to open almost any car using various technologies. However, this procedure will be paid and ranges from 3,500 rubles. But this price will be taking into account the working larvae. In an unpleasant situation, master keys will not bring results.
- Without the help of others, they open the car in another way. It is necessary to use a long wire and a wire with a light bulb. At the edge of the wire, you need to wrap it 90 degrees. After this, press off the upper part of the door using a board or kitchen spatula. It is recommended to work carefully so as not to destroy the paint on the car. After a gap appears, you need to push the wire in and try to get it out, and then pull the hood opening handle.
Next, you need to find the mounting block; in Octavia it is located on the left. The roof is opened and the relay is looked for (Main or Master Relay). Then it is removed and then you need to wire it to supply electricity from the battery, alternately pressing the relay contacts, this will turn on the ignition. A light bulb will be needed so as not to burn anything unnecessary. After turning on the ignition, you should open the window as at the beginning. If none of the described methods help, then the last method is to simply break the glass. In this case, replacing the batteries will not cost you, then it is better to use one of the above methods. When, using the services of burglars, from time to time it will be cheaper to break a window and pay for its replacement. Alas, the choice of one or other method remains with each car owner.
This, this is not the most humane way, unfortunately, in the absence of options, this method is the most suitable. It is recommended to find out the price of one or another window in advance. The one that will be cheaper is more practical to break.
Towards the end of the note, it must be said that changing batteries is an easy way to open a Skoda Octavia.
What to look for when choosing a battery for Skoda Octavia A5
The Skoda Octavia A5 uses batteries with reverse polarity. This means that the positive terminal is on the right and the negative terminal is on the left (where the battery terminals are closest to you). The location of the terminals is of great importance, since the length of the cables for connecting the battery is limited and will not be sufficient if a battery with a different terminal arrangement is installed.
Please be reminded that the positive and negative battery terminals are different sizes. According to European standards, the positive terminal has a diameter of 19.5 mm, the negative - 17.9 mm.
When choosing a battery, consider its size. Under the hood of the Skoda Octavia A5, the battery is located on a special platform equipped with mounts. Additionally, the battery is placed in a soft or plastic case. At the factory, batteries are installed with case dimensions of 207x175x175 mm, 207x175x190 mm, 242x175x175 mm, 242x175x190 mm, 278x175x190 mm. If you don't know the size of your battery, you can measure it, as well as the mounting pad, using a tape measure. Then it will be possible to determine exactly what parameters the battery should meet.

How to disassemble the door of Skoda Octavia A5?
You can disassemble the door mechanism lock on the Octavia A5 for several reasons.
Change the standard columns and be sure to do it with spacer rings
Or, as in our case, we disassemble the door to achieve proper sound insulation.
Also to the questions: how to remove the glass in the doors of the Skoda Octavia A5? or how to change the window regulator? — I will try to give comprehensive answers.
Disconnect the glass from the window lifter
To do this, remove two rubber plugs and lower the glass with the electric window so that two bushings appear in the technological hole (they can be black or white), see Photo:
And secure the glass with tape:
So, you need to slide two grommets inside the door! First the bushing has a smaller diameter, then a larger one. You can, for example, apply pressure: the main thing is not to damage the bolt. The bushings will fall inside; after disassembling the door, they can be easily pulled out.
We release the glass, lift it to the bottom with our hands and fix it with tape.
Drilling out the rivets
We take a drill for 10 and without fanaticism, with a little effort we drill 9 rivets in the front door (which ones - let’s look at the diagram!), There are only 7 of them in the back door.
Now you can remove the plate, remove the window regulator bushings and thoroughly vacuum the bottom of the door to remove chips.
