Programming general
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When only replacing the key blank, there is no need for programming.
The remote control contains functions for both immobilizer and remote key. This means that after replacing the remote control, it must be programmed with both function for immobilizer and remote control.
