Operating a modern car Skoda Kodiaq 2019 release is inextricably linked with the functioning of the electronic access key. One day you may notice that the remote control has stopped responding to button presses, and the central locking opens the doors only when you directly touch the tag on the door handle. This is a classic sign of a low battery, which does not mean a breakdown of the immobilizer system itself or the receiving module.
Many car owners immediately turn to dealerships, where they charge a significant amount for a simple replacement of the power source. In fact, the procedure does not require complex diagnostic equipment or specific auto mechanic skills. It is enough to know the design of the case, choose the right type of battery and follow a clear algorithm of actions to restore the functionality of the key fob in a couple of minutes.
Discharge diagnostics and choosing the right battery

If, when you press the lock or unlock button, the LED on the key body blinks dimly or does not light up at all, this is a sure signal for action. In some cases, the car may beep when you try to open the doors with the key fob, but not respond to commands, which also indicates a low battery.
For model Skoda Kodiaq 2019 release standard key uses a standard lithium battery CR2032. This is a common type of battery that can be easily found at any electronics or auto parts store. It is important not to confuse it with similar models, for example, CR2026 or CR2016, as they are thinner and will not provide stable contact inside the compartment.
When choosing a new element, you should pay attention to the manufacturer. Cheap analogues may have low capacity, which will lead to repeated replacement after a few months. It is best to give preference to brands with a good reputation, such as Varta, Renata or Maxell. The shelf life of such batteries is usually several years, so even a part purchased for future use will not have time to run out.
β οΈ Warning: Never attempt to charge a standard CR2032 lithium battery as this may cause it to explode. Use only new batteries from trusted manufacturers.
Sometimes owners are faced with a situation where the key stops working immediately after washing the car. In this case, the problem may be not only in the discharge, but also in oxidation of the contacts due to moisture ingress.

Tools and preparation for the replacement procedure
For a successful replacement of the power supply, you will not need a set of professional locksmith tools. The whole procedure is done manually, but having a small set of items will make the process easier and reduce the risk of damage to the case. You will need a new power supply, which we have already discussed, and a flat screwdriver or plastic card.
The use of a metal tool requires special care not to scratch the glossy surfaces of the key fob. If you have a plastic spatula to remove the skin of the cabin, it will fit perfectly. In extreme cases, you can use a thin coin or even a thumbnail if the case of the key has special notches.
It is best to work on a clean surface, for example, on a table covered with soft cloth. This will prevent the loss of small parts, such as the spring or the key metal plate itself, if it detachs. Lighting also plays an important role: make sure you see the inside of the battery compartment well.
β οΈ Warning: Before starting work, carefully examine the key case for cracks. If the case is damaged, when you try to open it can break completely, and you will need to replace the entire key fob.
Take your time and act consistently. The rush in such cases often leads to unnecessary damage to the plastic, which is then difficult to disguise. If you feel that some part is not amenable, stop and re-examine the design, you may be trying to open the key from the wrong side.

If you have a model with a single body without a folding key, the cover can be removed from the back. In this case, you need to find the seam around the perimeter of the body and carefully conduct it with a flat object until the latches are released. In some cases, the lid is only removed in one direction, so try different angles of application of force if it does not lend itself immediately.

In most keys. Skoda positive contact (with the inscription) should be facing upwards, to the lid, but this must be checked visually on the body of the compartment.
Insert the new battery into the socket, slightly pressing it to lock in place. Make sure it sits tight and doesn't hang around. If the amplifiers that hold the battery bent when removing the old one, carefully correct them with a thin object, but do not overdo it so as not to break the plastic.
Before closing the lid, it is recommended to check the operability of the key. Press any button on the key fob and see if the LED light will light up. If the light is bright and instantaneous, then the contact is established correctly. If the indicator does not respond, check the polarity and purity of the contacts again.
If you notice that the contacts inside the key have traces of oxidation or plaque, they can be gently wiped with a cotton swab soaked in alcohol. Allow the contacts to dry completely before installing the new battery. This will extend the life of the electronic module and provide reliable contact.
What to do if the battery does not fit?
If the new battery does not enter the socket, check its thickness. The standard CR2032 has a thickness of 3.2 mm. If you accidentally bought a thicker model, it will not fit. Do not try to insert it by force, as this can damage the body.
Case assembly and function testing
After successfully installing the battery and checking its operability, you can start assembling the key. Take a plastic cover and carefully combine it with the main body. Make sure all the latches are in their grooves. Slightly press the lid until a characteristic click, which will confirm its reliable fixation.
Then put the metal key back in place. Put it in the groove to the point and press the lock to make it snap. Scroll the key several times to make sure the folding mechanism works smoothly and does not jam. If the key does not fold or, conversely, is not fixed in the open position, it is possible that the lid is installed incorrectly.
Now it's time for the final test. Approach the car and check all the remote control functions: opening and closing doors, opening the trunk, and the panic function (syrene). If the car responds to all commands correctly, then the replacement was successful.
In some cases, if the key has not been used for a long time with a discharged battery, a synchronization procedure may be required. This usually happens automatically when you first press a button, but if this does not happen, consult the vehicleβs operating instructions for a synchronization code or contact the service.
