First of all, take a look at this picture.The "Loaded File" window displays the immobilizer file name. Ensure that a valid dump is stored.

The "Maker"window displays selected maker name. Ensure the right key maker selected.

The "info" windows display an important information:
1. Original transponder---Informs you about type of the original transponder
2. Allowed transponder---Informs you what type of transponders is suitable for the key maker
3. Data location---The immobilizer memory may be stored in various chips, the description informs you about from where you have to read a dump.

Some immobilizers can have various chipsets. In this case the field displays several possible chips. Find one of them inside of the immobilizer and

read it.
4. Data size---Each chip has certain memory size, the key maker accepts files with the described size.
5. Data format---This field appears in case of 93CXX eeprom seria.
There are two standards of data layout:
Intel format and Motorola format or Little Endian and Big Endian respectively.
The data layout depends on a chip-programmer that is used for eeprom reading.This field informs you what kind of format is suitable for the key maker.Usually you can see that both

formats are suitable. It means that the program can understand any data layout.

Create a key step by step
Firstly, run the key maker interface according to the vehicle and read information in the "Info" window. Watch theData location field describes the

memory chip. Find out the chip inside of the immobilizer and read it. Save the read data (dump).
Click the "OPEN IMMOBILIZER FILE" button and load the saved dump.
The program will analyse the dump.
If the dump is correct the "WRITE" button will become active and the "Keys" window will display the range of key numbers that can be created.
Take a look at the "Info" window, the Allowed transponder field.
Ensure you use a transponder exactly the indicated type.
Place the transponder into the coil.
Choose the key position you want create in the "Keys" window.
Click the "WRITE" button.
This starts the writing process and transponder will be stored with the appropriate data.
At this point you may be asked to save a new immobilizer dump.
The program displays a standard File Save dialog where you have to save the data.
After this you will be informed about the new data saved and must be written into the immobiliser.
