Removing the Customers Code

WARNING: This page is about a different car, the 2004 Buick Regal and 2004 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

Perform the following steps in order to remove the customers code:

  4. Press the HR button.
  5. Set the first 2 digits (0-19) of the code with the HR button.
  6. Set the next 2 digits (0-99) of the code with the MIN button.
