An EEPROM (non-volatile) memory is utilized in a broad variety of electronic devices, including car keys. It stores data, including the unique authentication codes or encryption keys that are recognized by your car when you use the key to unlock or start it. These codes are crucial because they let the car know that you have the right key and are authorized to drive it. If your EEPROM is damaged, the keys will not function properly.

Then, disconnect the electrical connectors. Pull it out. Then, you can read the EEPROM data with the SOIC8 clip or micro pincers connected to the programmer. Once you have the data you can save it to a file and then write it back into the EEPROM. You can use a program such as PonyProg to read the EEPROM data. Click on Read Device.

This method requires that you turn the ignition on and keep it on. Next make sure that the driver's door is locked of the vehicle with another key. Then, turn the key fob to its lock position, and aim it at the transmission receiver located in the front of the car above the mirror. Press and hold the unlock button for a couple of seconds. The horn will sound, and the key fob will begin to work. If the skoda keys aren't working, the transmitter inside may have become corrupted or unsynchronized with the vehicle's anti-theft system.

Keyless Entry Method The new generation of keyless entry systems - like the kind supplied with modern OCTAVIA as well as electric ENYAQ iV cars - features one ingenious safety feature that prevents thieves from "signal extension". A signal is sent to the vehicle and then to the key, which must reply within a specific time. If the key does not respond, the car cannot be unlocked and starts to ring its alarms. The car also can tell the key is near by with a sensor located in the door handle. The sensor sends an alert to the key's internal coil which in turn, responds by sending a signal to the sensor. If the sensor detects this, the car unlocks itself and can turn on the interior lights if set up to do so. Even the older keyless entry systems have an old-fashioned backup. If the remote doesn't work it is still possible to manually open the driver door. You can do this by sliding the blade away or, in some models, by pressing a button in the pocket.
