How to Reset a Skoda Key

Switch the ignition ON and mechanically lock the vehicle. Press the unlock button five times at intervals of 1 second on the remote control. A short horn tone will be heard.
The EEPROM Method
It can take some time for a professional locksmith to reprogram your key in the event that it ceases to function. In most cases, this means taking a look at the EEPROM to locate the unique code for the particular vehicle. This process is risky, and there's a possibility of destroying the data inside the module. This is the reason it's best to leave it to an expert locksmith.
An EEPROM is a non-volatile memory used in many electronic devices, such as keys for cars. It stores information, including the unique security codes or encryption keys that are recognised by your car when you use the key to unlock or start it. These codes are vital because they notify the car that you have the correct key and that you are authorized to drive it.
If your EEPROM is damaged the keys won't function properly. The problem is usually caused by using the incorrect key, or hitting the wrong buttons. skoda kodiaq key fob not working could try to reset it using a specific tool, but this method is not guaranteed to work. It is recommended to hire an expert with years of knowledge of programming keys for automobiles.
To reset your EEPROM you must remove the Kessy Module from the vehicle. This is the module located just above the accelerator pedal on the left side of the vehicle. Using a screwdriver, unscrew the single plastic clip holding it in the position. Then, unplug the electrical connectors. Take it out. Then you can read the EEPROM data using an micro pincer or SOIC8 clip connected to an electronic programmer. Once you have all the data, you can save the file and then write it back to the EEPROM.
You can use a program such as PonyProg to read the EEPROM data. Click on Read Device. The EEPROM dump appears as a hexadecimal array of characters. There are three distinct Hex values that are the KEY_CODE, key_count and the V_ARG_ENABLED. You must change all the other Hex values to 00 to "virginize" the chip. Once you have done this, you are able to flash the chip to restore its function.
Ignition Method
This method involves activating the car's system with a second key. It isn't applicable to all vehicles but it is possible to reset the key fob in case it's not functioning properly or the battery is dead. It should work if have pressed the buttons with force (people often attempt to press the unlock button repeatedly).
This method requires you to turn on the ignition and leave it on. Next, lock the driver's door of the car with a second key. Next, set the key fob in the lock position and point it at the transmitter on the front of the vehicle, above the mirror. Press the unlock button for several minutes. The horn will sound, and the key fob will begin to function.
If the skoda keys aren't working, the internal transmitter may have been damaged or not synchronized with your vehicle's anti-theft system. If this is the situation, it needs to be changed into a new program. This can be done with the help of an expert or an automotive locksmith.
If the key fob doesn't seem to be working after reprogramming it, you could be able to determine that the car has "forgotten" the key (if the car hasn't been used for 6m). This should still allow you to try a resync method in the user manual - remove the driver's door lock cap and lock, and then unlock the car using the key. It should re sync the key, if not then it's time to visit the dealer. This is usually the case with keys that are not functioning and is less than two minutes.
Keyless Entry Method
The latest generation of keyless systems, which are present in OCTAVIA vehicles of the present and electric ENYAQ-iV vehicles, comes with an innovative security feature to prevent thieves from "signal extension". A signal is sent to the car and then to the key, which must reply within a specific time. If the key doesn't reply, the vehicle cannot be locked and will ring its alarms.
The car also can tell that the key is close by using a sensor in the door handle. This works by sending an electrical signal to the internal coil inside the key, which then transmits the signal back to the sensor. If the sensor detects this, the car is able to unlock itself and turns on the interior lights if it is set to do so.
Even older keyless entry systems come with an traditional backup. If the remote doesn't work however, you can manually open the driver's door. You can do this by sliding the blade away or, in certain models, by pressing a button in the pocket. This method is especially useful if your key's battery dies or you've lost it.
Remote Control Method

It is possible that the battery terminals have come loose. They'll appear to be loose and then soldered into. Soldering them back in place will restore your key fob's full functionality. If you're not confident with this type of repair, consult an expert auto elect technician.

(Can be channel "21" on some Audi models.) Insert the new key fob into the door to the driver's side and press its unlock button twice within 5 seconds (often enough to reach the next available memory position).
Repeat this procedure for up four additional remotes. Make sure to switch off the ignition between programming each remote. You should hear a sound each time you successfully program the remote.
