If the serial number to get the code does not work, then there are two options:
- To give the device specialists for money
- Independently read the memory chip (EEPROM) and save to a file (dump) with the extension *. Bin. Typically the code is stored there.

Disassemble the unit, we find the desired chip and fed to it from the board. Next padpaivaem it necessary wires.

Basically it is a memory chip 24Cxx (24c01, 24c16, 24c32, etc.) that can be read via I2c with solder them 3 wires from the programmer. And do not forget to apply +5 volts (can be from a computer USB) through any diode to the 8th pin of the chip.

Here is a diagram of the simplest programmer for devices 24Cxx

Here is a simple diagram of another programmer.
It supports almost all types of the most commonly used memory chips, but does not always work correctly …


Here you can see the full version of programmer

 

Next programmer works with EEPROM 93c46. Other chips are not supported
Work is performed by the printer port LPT1:

Well, the fourth programming more serious ESMARTProg
Supports programming of over 500 types of devices of different companies – manufacturers
