Saab cars made since 1994 use an immobilizer system based on keys that are coded. A new transponder is required for inclusion of an additional key, and special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

It can be costly. It is recommended to always have a spare set of keys at hand.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to car when it is inserted into the ignition. The car is able to check if the signal matches the one on the key.

This will shield the pins from current, thus preventing them from being shorted. A diode allows current to only flow in only one direction. It has a visual indicator that is black, that shows the direction in which the current will flow.

A few of the tools that are available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY customers in certain cases replace keys in the program and restore lost immobilizer data, Sanabria says.

The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite the gasoline in the engine compartment.
