Corresponds to VAG 1551/2 Function 16, (KWP-2000 only)

The Security Access Function must be used on some (but not all) KWP-2000/CAN/UDS Control Modules before you can Recode or change Adaptation values. On others, it "enables" certain features like cruise control. Valid Login codes can be found in the Factory Repair Manual for your car.

Balloons: VCDS can show Security Access "charts" when appropriate information is available in a Label File for the control module in question. The balloon will appear when the mouse cursor is hovered over the Enter security access key field.

For certain immobilizer functions, you can select the largely obsolete [Use 7-digit PIN/SKC] button to enter a 7-digit Secret Key Code as explained on this page.

The Option field is only to be used if you are given specific instructions from Ross-Tech.

Use the [Do It!] button to save the Login and return to the Open Controller Screen.

Use the [Cancel] button to cancel the Login and return to the Open Controller Screen.
