lmportant information on Programming 

Security code 

The security code protects the antitheft control unit 
against unauthorized programming and data access 
from Tech-2. The security code consists of a 4 digit 
code number and is programmed into the antitheft 
Control Module (ACU). 

New control units are not programmed with a security 
code.  

If the control units are replaced, the security code 
entered in the transmitter (into remote key).  

Must be programmed into the new control unit with 
Tech-2. 

The security code can only be programmed with Tech-2 
once and must therefore be performed with great care. 

Once programmed, the security code cannot be 
overwritten. An already used antitheft can be reused in 
a different car by initializing the antitheft. After that you 
can program the security code again. For initializing 
command you need the current security code. 

If the antitheft control unit is returned, always enclosed 
the security code that is allocated to that control unit. If 
this is not done, we can not process the case and the 
warranty will not be recognized. 

 

Entering a code 

If the Tech-2 display requests that the 
• security 

code 

•  Vehicle Identification No. 
•  Country code (Select 213 Germany in all items) 
be entered, process as follows; 

To input a digit you need to use the up and down 
buttons of the Tech-2. By using the numeric buttons the 
according digit will be displayed at the current position 
and the cursor will move to the next position. 

For letters you need to use the up and down buttons of 
the Tech-2. The up and down key might be used for 
digits as well. By using the up and down buttons the 
displayed digit or letter will be increased or decreased.  

To move to the next position you need to use the move-
to-right-button. 

With the two buttons, move-to-right and move-to-left 
you can select the position of number you want to 
change.  

This will allow you to correct a wrong number. 

After the number is completed you need to press the 
Enter button to accept the number. Correction is now no 
longer possible. 

 

 

Use the OKAY soft key to program the number and the 
NOT OKAY soft key to abort the programming.
