17 Signs To Know You Work With Skoda Key Reset
How to Reset a Skoda Key

I just got a message that my infotainment device is low on battery and has to be replaced. It's not the first time and when I last visited a dealer they just replaced it for free, took 2 minutes and told me it would be working again.

Switch the ignition ON and lock the vehicle mechanically. Press unlock button on remote control 5 times at 1 second intervals. A short horn will sound.

EEPROM Method

It could take some time for a professional car locksmith to reprogram your keys if it ceases to function. In many cases, the EEPROM is scanned to determine the unique code of the car. This process is risky, and there's a likelihood of damaging the information inside the module. This is why it's better to trust an expert locksmith.

An EEPROM (non-volatile) memory is used in a wide variety of electronic devices like car keys. It is a storage device that stores the unique authentication codes and encryption keys that your car recognises when you use it to unlock or start the car. These codes are important because they inform the car that you have the correct key and are authorized to drive it.

If your EEPROM is damaged the keys won't work. The problem is typically caused by using the wrong key, or by hitting the wrong buttons. It is possible to reset the key by using an instrument that is specifically designed for this purpose. However this method might not 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 just above the accelerator pedal on the left side of the car. With a screwdriver, remove the single plastic clip holding it in the position. Then, disconnect the electrical connectors. Take it out. Then, you can read the EEPROM data using an micro pincer or a SOIC8 clip connected to the programmer. Once you have all the data you are able to save the file, and then write it back into the EEPROM.

You can make use of a program like PonyProg to read the EEPROM data. Click on Read Device. The EEPROM dump will show up as an array of hex characters. There are three distinct values in hex: the KEY_CODE, the key_count, and the V_ARG_ENABLED. To "virginize", the chip, you must change the other hex values to the value 00. After you've done this, you can then flash the chip to restore its functionality.

Ignition Method

This method involves using an additional key that works to activate the car's system. It might not work on all vehicles, but it can reset the key fob when it isn't working or the battery has died. It should work if you have pressed the buttons hard (people often push the unlock button repeatedly).

This method requires you to switch on the ignition and leave it on. Then, mechanically lock the car's drivers door using a different key. Next, turn the key fob back to its lock position and point it at the transmission receiver located in the front of the vehicle above the mirror. Hold the unlock button for several seconds. The horn should sound, and the key fob will start working.

If the skoda keys aren't functioning, the transmitter inside may have become corrupted or not synchronized with the vehicle's anti-theft system. This requires the reprogramming of the device. This can be accomplished with the help of an expert technician or an automotive locksmith.

If the key fob won't work after reprogramming it could be because the car "forgot" the key if the car was not used for 6 months. This should still allow you to try a resync method in the user's manual - remove the driver's door lock cap and lock, and then unlock the car with that key. If it doesn't work, you'll need to visit the dealer. This is typically the case for keys that are not functioning and takes less than 2 minutes.

Keyless Entry Method

The new generation of keyless systems, which are present in the latest OCTAVIA cars as well as electric ENYAQ-iV cars, comes with an innovative security feature that can prevent thieves from "signal expanding". The car transmits an alert and the key has to respond within a set time. If the key fails to respond, the vehicle will not be unlocked and it will sound alarms.

A sensor in the handle of the door can also be used to inform the car that the key is near. This works by sending an indication to the key's internal coil, that then responds by sending the signal to the sensor. If the sensor detects it, the car will unlock itself and switch on the interior lights automatically, if it is set to do this.


Even the older keyless entry systems come with an old-fashioned backup. If the remote doesn't work, you may unlock the door for the driver mechanically by sliding out the blade or, in certain models, pressing down on a button within the door pocket. This is especially helpful in the event that your key's battery is dead or you have lost it.

Remote Control Method

If you've recently purchased a remote control and it doesn't work in your car it could be because the seller didn't have programmed it correctly to your vehicle. It could also be that the battery terminals are loose (look for this, they could appear a bit loose to the touch and sometimes soldered in the wrong place) - carefully soldering them back in place should return your key fob to its original working condition. If you're unsure about this kind repair, you should consult a professional auto technician.

Switch ignition OFF and physically lock the car from within by using a second, unmatched key (this resets memory position 1). they said "01" (may be channel "21" in some Audi models). Insert the new key fob in the door to the driver's side and then press its unlock button twice in 5 seconds (often enough to reach the next available memory position).

Repeat this process for up to four additional remote controls. Be sure to turn off the ignition between programming each remote. You will hear a chime every time you successfully code the remote.
