Method of EEPROM
It may take a while for a professional locksmith to reprogram your keys if it stops working. In most cases, the EEPROM is analyzed to discover the unique code of the car. This process is risky, and there's a chance of corrupting the information in the module. It's best to leave this to an experienced locksmith.
An EEPROM (non-volatile) memory is utilized in a broad range of electronic devices including car keys. It stores information that includes the unique authentication codes as well as encryption keys that your vehicle recognises when you use it to unlock the vehicle or start it. These codes are crucial because they let your car know that you are the owner of the key and that you have the right to drive.
If your EEPROM is damaged, the keys will stop working. The issue is caused by pressing the wrong key or accidentally hitting the wrong key. It is possible to reset the key by using a special tool. However this method might not work. It is better to work with a professional who has extensive experience in automotive key programming.
To reset your EEPROM, you must first remove the Kessy module from the vehicle. It is located just above the accelerator pedal on the left side of the vehicle. Remove the plastic clip that is holding it in place using the screwdriver. Then, unplug the electrical connectors. Remove it. You can then read the EEPROM with a SOIC8 or micro pincers that are connected to a programmer. Once you have all the information, you can save the file and write it back to the EEPROM.
You can make use of a program like PonyProg to read the EEPROM data. Click on Read Device. The EEPROM dump appears as a hexadecimal array of characters. Three hex values stand out for the KEY_CODE (key_code), the key_count (key_count) and the V_ARG_ENABLED. You must change all the other Hex values to 00 to "virginize" the chip. After you've done this, you can flash the chip to restore its functionality.
Ignition Method
This method involves activating the car's system using another key. It isn't applicable to all vehicles however it is possible to reset the key fob if it isn't working properly or the battery is dead. It should work if have tried pressing the buttons repeatedly (people often push the unlock button repeatedly).
This method requires you to switch on the ignition and keep it turned on. Then, mechanically lock the car's drivers door using a different key. Then, put the key fob in the lock position and point it towards the transmission transmitter located on the front of the car, just above the mirror. Press and hold the unlock button for a couple of seconds. The horn will sound, and the key fob will start to work.
If the skoda keys don't work, it could be that the transmitter inside has been damaged or out of alignment with the vehicle's security system. This will require the reprogramming of the device. This can be done with the help of an expert technician or an automotive locksmith.
If the key fob is not working after reprogramming it, it may be that the car has "forgotten" the key (if the car hasn't been used in 6 months). You can try the resync procedure in the user's guide Remove the cap and lock from the driver's side of the door. Then unlock the car with that key. The key should be able to sync again. key, if not then it's a trip to the dealers. This normally works on keys that have lost their functionality and takes less than two minutes to do.
Keyless Entry Method
The new generation of keyless entry systems - like the type that is used in modern OCTAVIA and electric ENYAQ iV cars - features one ingenious safety feature that blocks thieves from "signal extension". The car sends an alert and the key must reply within a certain time. If the key does not respond then the car will not be unlocked. It will begin to sound alarms.
The car can also tell the key is near by by using a sensor in the door handle. This works by sending a signal to the key's internal coil that then responds by sending a signal to the sensor. If the sensor detects it then the car will open itself and turn on the interior lights automatically if it is set to do this.
Even older keyless entry systems have an alternative. If the remote does not work, you may open the door of the driver mechanically by slipping out the blade or, in some models, by pressing down on a button inside the door pocket. This method is especially useful if you've lost your key or the battery has died.
Remote Control Method
If you've recently purchased an entirely new remote control but it's not working in your car, it's possible that the seller didn't set it up to work with your vehicle. It could be that the battery terminals are loose (look for this, they may feel a bit loose to the touch and may be soldered in place) - carefully soldering them back in place should restore your key fob to working order. If you're not sure about this type of repair, consult an expert auto elect technician.
Turn off the ignition and lock the car from inside using an unmatched key (this resets memory position 1). Enter channel "01" (may be channel "21" in certain Audi models). Insert skoda key reset thekeylab.co.uk in the driver's door, and then press the unlock button two times in less than 5 seconds.
Repeat this coding process for up to four additional remotes - make sure to switch off the ignition when programming each remote. You should hear a chime each time you successfully code the remote.
