EEPROM Method It can take some time for a professional locksmith to reprogram your key in the event that it ceases to function. In a lot of instances the EEPROM is scanned to determine the unique code of the car. This is a risky process because there's a high chance that the information stored in the module will be damaged. It's best to leave this to an experienced locksmith. An EEPROM is a non-volatile memory utilized in various electronic devices, such as keys for cars. 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 crucial because they notify the car that you've got the correct key and are authorised to drive it. If your EEPROM is damaged, the keys will cease to function. The problem can be caused by pressing the wrong key or accidentally hitting the wrong key. You could attempt to reset it using a special tool but this method is not certain to work. It is recommended to employ an expert who has years of knowledge of programming automotive keys. To reset your EEPROM you must remove the Kessy Module from the vehicle. This is the module located above the accelerator pedal on the left side of the vehicle. Utilizing a screwdriver to remove the single plastic clip holding it in the position. Then, disconnect the electrical connectors. Pull it out. Then you can access the EEPROM data with a micro pincer or SOIC8 clip connected to a programmer. Once you have all the data, you can save the file and write it back into the EEPROM. To read the EEPROM data, utilize a program like PonyProg and click Read Device. The EEPROM dump will be displayed as an array of hex characters. There are three hex values that are the KEY_CODE, key_count, and the V_ARG_ENABLED. To “virginize”, the chip, you must change the other hex values to 00. Once you've completed this, you can flash the chip to restore its functionality. Ignition Method This method requires activating the car's security system with another key. It might not work for all vehicles however it is able to reset the key fob in cases where it's not functioning or the battery is dead. It should work if you have tried pressing the buttons repeatedly (people often attempt to press the unlock button repeatedly). To apply this method, turn on the ignition and then leave it on. Next you must lock the door of the driver of the car with another key. Then, turn the key fob to its lock position, and aim it at the receiver for transmission located in the front of the car above the mirror. Hold the unlock button down for several minutes. The horn will sound and the key fob will begin to function. If the skoda key isn't working, the internal transmitter could be damaged or not synchronized with your vehicle's anti-theft system. If this is the case, the key will need to be reset. This can be accomplished with the help of an expert technician or an automotive locksmith. If the key fob isn't working after reprogramming it, it may be that the car has “forgotten” the key (if the vehicle hasn't used in 6 months). You can try the resync procedure in the user's manual – remove the cap and lock on the driver's side door, then unlock the car with that key. If it doesn't, you'll need to visit the dealer. This usually happens with keys that have lost their function, and it takes less than 2 minutes to do. Keyless Entry Method The latest generation of keyless entry systems, such as the ones that are included in the latest OCTAVIA and ENYAQ iV vehicles – has one ingenious safety feature that prevents thieves from “signal extension”. A signal is sent to the car and then to the key, which must respond within a certain time. If the key doesn't reply the car can't be locked. It will start to sound alarms. The car can also detect the key is near by through a sensor on the door handle. The sensor sends an indication to the key's internal coil, that then responds by sending an indication to the sensor. If the sensor detects it then the car will open itself and turn on the interior lights automatically, if the key is programmed to do that. Even the older keyless entry systems come with an traditional backup. If the remote doesn't work however, you can manually open the driver door. This can be done by sliding the blade away or, in certain models, pressing a button in the pocket. This is especially helpful in the event that your key's battery is dead or you've lost it. Remote Control Method If you've just bought a remote control that does not work in your vehicle, the seller might not have programmed it correctly to your vehicle. It could be that the terminals of the battery are loose (look for this, they might feel a bit loose to the touch, and then sometimes soldered in the wrong place) It is important to carefully solder them back into place will return your key fob to its original working condition. If you're not confident with this sort repair, you should consult a professional auto elec technician. Switch ignition OFF and physically lock the car from inside by using a second, unmatched key (this resets memory position 1). Enter channel “01” (may be channel “21” in certain Audi models). Insert the new keyfob into the driver's door and press the unlock button two times in less than 5 seconds. Repeat this coding procedure for up to 4 additional remote controls – be sure to switch off the ignition before programming each remote. You should hear a sound every time you successfully program the remote.
