The EEPROM Method
It may take a while for a professional locksmith to reprogram your key if it stops working. In most instances, this requires reading the EEPROM to determine the unique code for that specific vehicle. This process is risky, and there's a good possibility of destroying the data inside the module. It is best to leave this to a skilled locksmith.
An EEPROM is an in-built memory that is non-volatile and can be found in various electronic devices, including car keys. It stores information that includes the unique authentication codes and encryption keys that your vehicle recognizes when you use it to unlock or start the car. These codes are essential because they inform your car that you are the owner of the key and that you have permission to drive.
If your EEPROM is corrupted, the keys will cease to function. The problem is caused by pressing the wrong button or accidentally hitting the wrong key. It is possible to reset the key by using an appropriate tool. However this method might not work. It is better to work with an expert who has years of experience in programming automotive keys.
To reset your EEPROM, you must remove the Kessy Module from the vehicle. This is the module above the accelerator pedal located on the left side of the car. With a screwdriver, remove the single plastic clip holding it in the position. After that, disconnect the two connectors to electrical power and remove it from the vehicle. Then, you can access the EEPROM by using a SOIC8 and micro pincers that are connected to the programmer. Once you have all the data you can save the file and then write it back to the EEPROM.
To read the EEPROM data, use a program like PonyProg and click Read Device. The EEPROM dump appears as an array of hexadecimal characters. There are three distinct Hex values: the KEY_CODE, the key_count and the V_ARG_ENABLED. To "virginize", the chip, you must change all other hex values starting with 00. Once you have done this you are able to flash the chip to restore its functionality.
Ignition Method
This method uses an additional key that works to activate the car's security system. It may not work with all cars however it is able to reset the key fob in cases where it's not working or the battery has died. It should also work in the event that the buttons are pushed hard (a common reason for this is pressing down the unlock button multiple times).
To apply this method, turn on the ignition and turn it off. Then you must lock the door of the driver of the car using another key. Then, turn the key fob to its lock position and point it at the transmission receiver located on the front of the car above the mirror. Press and hold the unlock button for a few seconds. The horn will sound, and the key fob should begin to work.
If the skoda keys do not work, it could be that the transmitter inside has been damaged or out of sync with the vehicle's theft-deterrent system. If this is the situation, it needs to be changed into a new program. A locksmith technician or auto locksmith can assist you in this.
If the key fob won't function after reprogramming it, it could be that the car "forgot" the key if the car was not used for six months. This should allow you to try a resync method in the user's manual. take off the driver's door lock cap and lock, and then unlock the car with the key. If how to unlock skoda octavia without key doesn't work, you will need to visit the dealer. This is usually the case with keys that are no longer working and takes less than 2 minutes.
Keyless Entry Method
The new generation of keyless systems that are used in modern OCTAVIA cars and electric ENYAQ-iV vehicles, comes with an innovative security feature to protect against thieves "signal expanding". The car sends an alarm and the key must reply within a certain time. If the key isn't responsive then the car will not be locked. It will start to ring alarms.
The car can also tell the key is near by through a sensor on the door handle. It works by sending an alert to the key's internal coil, which in turn, responds by sending the signal to the sensor. If the sensor detects this, the car will unlock itself and can turn on the interior lights if set to do this.
Even older keyless entry systems come with an older-fashioned backup. If the remote doesn't work, you can still manually open the door to the driver. You can do this by sliding the blade away or, in some models, pressing a button in the pocket. This method is especially useful when the battery of your key is dying or you've lost it.
Remote Control Method

Repeat this procedure for up four additional remote controls. Be sure to switch off the ignition between programming each remote. You will hear a chime every time you successfully code the remote.
