20 Up-And-Comers To Watch In The Skoda Key Reset Industry
How to Reset a Skoda Key
Just got a message from my infotainment device to say the key battery is low and requires replacement. It's not the first time and last time I went to an auto dealer, they replaced it at no cost, took 2 minutes and told me it would be working again.
Switch the ignition ON and secure the vehicle mechanically. Press the unlock button five times in intervals of 1 second on the remote control. A short horn tone will be heard.
Method of EEPROM
It may take a while for a professional car locksmith to reprogram your key in the event that it ceases to function. In many cases the EEPROM is read to find the unique code of the car. This is a risky process, and there's a high possibility of destroying the data within the module. It is best to leave this to a skilled locksmith.
An EEPROM (non-volatile) memory is used in a wide variety of electronic devices, including car keys. It stores information that includes the unique authentication codes as well as encryption keys that your car recognises when you use it to unlock the vehicle or start it. These codes are vital because they inform your car that you are the owner of the key and have permission to drive.
If your EEPROM is corrupted, the keys will cease to function. The issue is caused by pressing the wrong key or accidentally hitting the wrong key. You may attempt to reset it using a special tool however, this isn't 100% guaranteed to work. It's better to use an expert who has years of experience in automotive key programming.
To reset your EEPROM you must remove the Kessy Module from the vehicle. This is the module that sits above the accelerator pedal, on the left side of the vehicle. Take off the clip made of plastic that holds it in place with a screwdriver. After that, unplug the two electrical connectors and remove it from the vehicle. Then you can read the EEPROM data with a micro pincer or SOIC8 clip connected to the programmer. Once you have all the information you are able to save the 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 will appear as an array of hex characters. There are three Hex values: the KEY_CODE, the key_count and the V_ARG_ENABLED. You must change all the other hex values to 00 to "virginize" the chip. Once you do this you are able to flash the chip and restore its functionality.
Ignition Method
This method requires another key to activate the car's security system. It's not applicable to all vehicles, however it is possible to reset the key fob in case it's not working properly or the battery is dead. It should work if you have pressed the buttons with force (people often try to push the unlock button repeatedly).
This method requires that you turn the ignition on and keep it on. Next, lock the driver's door of the car with another key. Then, put the key fob in the lock position and point it towards the transmitter on the front of the car, just above the mirror. Press the unlock button for a few minutes. The horn will sound and the key fob should begin to work.
If the skoda keys aren't working, the transmitter inside may have been damaged or not synchronized with the vehicle's anti-theft system. This requires changing the program. A locksmith technician or auto locksmith can assist you with this.
If the key fob won't work after reprogramming it could be because the car "forgot" the key in the event that the car was not in use for 6m. It is still possible to try a resync method in the user's manual - remove the door lock for the driver's cap and lock and then open the car with the key. If it doesn't work, you'll need to visit the dealer. This usually happens with keys that have lost their functionality, and it takes less than 2 minutes to do.
Keyless Entry Method
The latest generation of keyless systems that are used in modern OCTAVIA cars and electric ENYAQ-iV vehicles, comes with an innovative security feature to prevent thieves from "signal expanding". A signal is sent to the vehicle and then to the key, which is required to respond within a certain time. If the key doesn't reply, the vehicle cannot be unlocked and starts to ring its alarms.
The car also can tell that the key is nearby through a sensor on the door handle. It works by sending an electrical signal to the internal coil of the key, and then transmits the signal back to the sensor. If the sensor detects it then the car will open itself and activate the interior lights automatically if the key is programmed to do this.
Even older keyless entry systems come with a backup. If the remote does not work, you may unlock the door for the driver mechanically, either by sliding out the blade or, with certain models, by pressing down on a button within the door pocket. This method is particularly helpful when the battery of your key is dying or you've lost it.
Remote Control Method
If you've recently purchased an electronic remote control but it doesn't work in your car it could be because the seller didn't have programmed it to match your vehicle. It could also be that the battery terminals have become loose. They'll appear to be loose and then soldered in. Soldering them back into place should bring back the full function. If you're not comfortable with this sort of repair, seek out an expert auto electrician.
Switch ignition OFF, and then lock the vehicle from within with the second key that's not matched (this resets the memory position 1). Enter channel "01" (may be channel "21" in some Audi models). Insert the new key fob into the door to the driver's side and then press the unlock button twice in 5 seconds (often enough to reach the next available memory position).
Repeat how to unlock skoda octavia without key coding process for up to 4 additional remote controls. Make sure to shut off the ignition before programming each remote. You should hear a tone every time you successfully program the remote.
