NOTE: When the keys are lost you must replace both the twice unit and the chip that goes into the key as an assembly and they must be married together with the Saab Tech 2 Scan tool in-order for them to function. You will also need to get a key cut so you won't have to replace your complete ignition switch.
NOTE: The House brand of Twice unit alarms is the OES module that we are remapping. You will still have to program the alarm at your local Saab dealer
