How to Reset a Skoda Key

I just received a message from my infotainment device to inform me that the battery for my key is low and requires replacement. It's not the 1st time, and last time I visited an auto dealer, they replaced it for free in 2 minutes and said it will be working again.

Switch ignition ON and lock the vehicle mechanically. Press skoda octavia key programming at intervals of 1 second on the remote control. A short horn tone will sound.

EEPROM Method

It may take a while for a professional locksmith to reprogram your keys if it stops working. In many cases, this means taking a look at the EEPROM to find the unique code for the particular car. This is a risky procedure since there's a great chance that the information stored in the module could be damaged. This is why it's best to trust an skilled locksmith.

An EEPROM is an in-built memory that is non-volatile and can be found in various electronic devices, such as keys for cars. It stores data, which includes the unique security codes or encryption keys that are recognised by your car when you use the key to unlock it or start it. These codes are vital because they let the car know that you have the right key and that you are authorized to drive it.

If your EEPROM is corrupted, the keys will cease to function. The issue is caused by pressing the wrong button or accidentally hitting the wrong key. You may try to reset it by using a special tool but this method is not guaranteed to work. It is recommended to hire an expert with years of knowledge of programming keys for automobiles.

To reset your EEPROM, you must first remove the Kessy module from the vehicle. It's located just above the accelerator pedal on the left side of the car. Take off the plastic clip that is holding it in place using the help of a screwdriver. Then, unplug the electrical connectors. Take it out. Then you can read the EEPROM data with a micro pincer or SOIC8 clip connected to the programmer. Once you have the data you can save it as 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. The EEPROM dump appears as a hexadecimal array of characters. There are three values in hex including the KEY_CODE key_count, and the V_ARG_ENABLED. To "virginize", the chip, change all other hex values from the value 00. After this you are able to flash the chip and restore its functionality.

Ignition Method

This method requires activating the car's system with an additional key. It might not work on all vehicles however it is able to reset the key fob when it isn't working or the battery has gone out. It should work if you have tried pressing the buttons repeatedly (people often push the unlock button repeatedly).


To do this switch on the ignition and leave it on. Next, lock the driver's door of the car with a second key. Then, rotate the key fob back to its lock position, and aim it at the receiver for transmission located on the front of the car above the mirror. Hold the unlock button down for a few minutes. The horn should sound, and the key fob will start working.

If the skoda keys aren't working, the internal transmitter could be damaged or unsynchronized with the vehicle's anti-theft system. This requires reprogramming. 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 in the event that the car wasn't used for 6m. This should still allow you to test a resync option in the user's manual - remove the door lock for the driver's cap and lock, and then unlock the car with that key. It should re sync the key, but if it doesn't, you'll need to visit the dealer. This normally works on keys that have lost their functionality, and it takes less than two minutes to complete.

Keyless Entry Method

The latest generation of keyless entry systems - the type that is used in modern OCTAVIA and electric ENYAQ iV vehicles - has an innovative security 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 fails to respond, the car cannot be locked and will sound alarms.

A sensor in the handle of the door can also be used to tell the car that the key is in close proximity. This works by sending an electrical signal to the internal coil of the key, and then returns a signal back to the sensor. If the sensor detects it, the car will unlock itself and activate the interior lights automatically if it is set to do this.

Even older keyless entry systems come with an traditional backup. If the remote does not work, you can open the driver's door mechanically by slipping out the blade or, in certain models, by pressing down on a button within the door pocket. This method is especially useful if your key's battery dies or you've lost it.

Remote Control Method

If you've recently purchased an entirely new remote control but it's not working in your car, it's possible that the seller didn't set it up to work with your vehicle. It could also be that the battery terminals have become loose. They will appear to be loose and then soldered in. Soldering them back into place will bring back your key fob's full functionality. If you're not confident with this kind repair, you should consult an expert auto elect technician.

Turn off the ignition and secure the car from the inside with another key that is not matched (this resets memory position 1). Enter channel "01" (may be channel "21" in certain Audi models). Insert the new keyfob into the driver door and press the unlock button twice in less than 5 seconds.

Repeat this process for up four additional remote controls. Be sure to turn off the ignition between programming each remote. You should hear a tone each time you successfully program the remote.
