The EEPROM Method
If your car's key stops working, it may take a while for a professional to reprogram it. In most instances, the EEPROM is scanned to determine the unique code of the car. This process is risky and there's a good likelihood of damaging the information inside the module. It's best to leave this to a professional locksmith.
An EEPROM is a non-volatile memory utilized in various electronic devices, including car keys. It stores information, including the unique authentication codes or encryption keys that are recognised by your car when you use the key to lock or start it. These codes are vital because they let your car know that you are the owner of the key and have the right to drive.

With a screwdriver, remove the single plastic clip that holds it in place. After that, disconnect the two connectors to electrical power and remove it from the vehicle. Then, you can read the EEPROM data using a SOIC8 clip or micro pincers connected to an electronic programmer. Once you have the data you can save it as a file and then write it back into the EEPROM.
You can utilize a program like PonyProg to read the EEPROM data. Click on Read Device. The EEPROM dump will be displayed as a series of hex characters. There are three Hex values including the KEY_CODE key_count, and the V_ARG_ENABLED. You need to change all other Hex values to 00 to "virginize" the chip. After this, you can flash the chip to restore its functionality.
Ignition Method
This method involves activating the car's system using a second key. It does not work on all vehicles, but it will be able to reset the key fob in case it's not functioning properly or the battery is dead. It will work if you have pressed the buttons with force (people often push the unlock button repeatedly).
This method requires that you turn the ignition on and keep it turned on. Next make sure that the driver's door is locked of the vehicle with a second key. Next, set the key fob in the lock position and point it towards the transmitter on the front side of the car, just above the mirror. Press the unlock button for a few seconds.

Keyless Entry Method
The new generation of keyless systems, which are found in modern OCTAVIA cars and electric ENYAQ-iV cars, comes with an innovative security feature that can stop thieves from "signal extension". The car transmits an alert and the key must reply within a set time. If the key doesn't respond, the car cannot be unlocked and starts to sound alarms.
The car also can tell that the key is close with a sensor located in the door handle. It works by sending an electrical signal to the internal coil of the key, which sends a signal back to the sensor. If the sensor detects this, the car unlocks itself and turns on the interior lights, if set to do this.
Even older keyless entry systems have an alternate. If the remote isn't working, you can still manually open the driver door. This can be done by sliding the blade or, in certain models, pressing a button on the pocket. This is particularly useful if you've lost your key or if the battery has gone out.
