EEPROM Method
If your car's key isn't working, it could take an extended time for a professional to reprogramme it. In a lot of instances, the EEPROM is read to find the unique code of the car. This process is risky and there's a possibility of destroying the data in the module. It's best to leave this to an experienced locksmith.
An EEPROM is a non-volatile memory utilized in a variety of electronic devices, including keys for cars. It is a storage device that stores the unique authentication codes and encryption keys that your car recognizes when you use it to unlock the vehicle or start it. These codes are important because they let the car know that you've got the correct key and are authorized to drive it.

Utilizing a screwdriver to remove the single plastic clip that holds it in place. After that, you can disconnect the two connectors to electrical power and pull it out of the vehicle. Then you can read the EEPROM data with the SOIC8 clip or micro pincers connected to a programmer. Once you have all the information you can save the file and write it back to the EEPROM.
To read the EEPROM data, utilize a program like PonyProg and click Read Device. The EEPROM dump will appear as a hex array of characters. Three hex numbers are noteworthy for the KEY_CODE (key_code), the key_count (key_count) and the V_ARG_ENABLED. It is necessary to change all other hex values to 00 to "virginize" the chip. Once you do this you are able to flash the chip and restore its functionality.

This method involves activating the car's security system with an additional key. It may not work with all cars, but it can reset the key fob if it's not functioning or the battery is dead. It should work if you have pressed the buttons hard (people often push the unlock button repeatedly).
To apply this method switch on the ignition and leave it on. Then, lock the door to the driver's compartment with another key. Then, put the key fob in the lock position and point it towards the transmission transmitter located on the front side of the car above mirror. Press and hold the unlock button for a few seconds. The horn should sound, and the key fob should begin working.

The new generation of keyless systems that are used in modern OCTAVIA cars and electric ENYAQ-iV vehicles, has an innovative security feature that can prevent thieves from "signal extending". A signal is sent to the car and then to the key, which is required to respond within a specified time. If the key isn't responsive the car can't be locked. It will begin to ring alarms.
A sensor located in the door's handle could also be used to tell the car that the key is nearby. It works by sending a signal to the key's internal coil, which in turn, responds by sending an indication to the sensor. If the sensor detects this, the car will unlock itself and can turn on the interior lights, if set to do so.
Even older keyless entry systems come with an traditional backup. If the remote doesn't work it is still possible to manually open the driver's door. This can be done by sliding the blade or, in some models, by pressing a button on the pocket. This is particularly useful if you've lost your key or if the battery has gone out.
