This Tester Key is specially designed to help you determine the correct Generation of your Prodecoder (VAG)of the lock – if it is 1st OR 2nd one.
When the key goes to the RED dot = the lock is Generation 1
When the key goes to the GREEN dot = the lock is Generation 2
If the Prodecoder HU66 for Both Generation 1 or 2 is put into the NOT corresponding lock, the Prodecoder may be damaged.
