Key Programming via OBD
General Instructions
- The PIN and CS codes are required for key programming.
- For some models it is possible to read immo data from engine ECU.
- If programmer fail to read the data via OBD - perform Eeprom/Bench method.
Key Programming via EEPROM
Unit - KESSY
2 versions: Encrypted (2008+ Continental/Siemens VDO) and Unencrypted (-2008 Siemens VDO/Siemens VDO)
Unencrypted - Read eeprom 93C86
Encrypted - Reading with in-circuit connection (refer to Kessy 2008+ of your programmer)
KESSY Location
Located in the driver's footwell
Eeprom reading
Recommended out-circuit reading.Use EEPROM adapters, most programmers can handle the readout.
KESSY (-2008)
Read eeprom 93C86
KESSY (2008+)
Reading with in-circuit connection (refer to Kessy 2008+ of your programmer)

Decoding Tips
- HU66 generations two and three locks wafers are 2 up 2 down
- The lock has 8 spaces and 4 depths.
- Audi A8 and some VW Touareg use a 9-cut lock, the 9th cut is a generic cut the same in every lock. All cut to code machines have the facility to cut this 9th cut automatically if selected.
- The same eight cuts on both sides of the key.
- To decode the lock read in the SAME direction as it was picked.
- Picking rule: if the wafer moves at all leave it alone.
