General Instructions
- If the system is locked try to unlock the system by disconnecting the tester and turn ignition off for 15 minutes then ignition on for 5 minutes
- Pressing a remote when it is desynchronised can cause the BSI to enter antiscanning mode for 1 minute when synchronisation is not possible.
- The old keys not programmed as part of key programming procedure will never be able to be re-programmed (newest models).
