10 Myths Your Boss Has About Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 come with an immobilizer system made up of coded keys. In order to add a second key, it requires a new transponder and special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
The problem is that this can be very expensive. This is the reason why you should always have a spare key available.
Transponder key
The transponder is a key with an electronic chip. This chip sends a signal when the key is placed in the ignition. The car is able to check whether the signal matches the one on the key. If both signals match, the car will unlock itself and start. This is a fantastic way to safeguard your car from theft.
Transponder keys may be a popular addition to cars, but they're not as secure as traditional keys made of metal. While the metal component of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. This chip contains an unique code that's programmed into a car's computer in order to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. The car will only recognize the key fob if it has an unmodified chip and has been programmed to match. Otherwise, the car would reject the key and refuse to start.

It includes 5 rows and 17 column.
After the columns and rows are soldered together, it is time to connect the key switches. To do this you must place an inverter over each pin on the key switch and solder it. This will shield the pins on the key switch from current and also prevent them from being shorted. The diode allows current to only flow in only one direction. It features a visual indicator, a black band, that indicates which direction current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may help customers in the shop, or even DIY customers in certain cases program replacement keys and restore lost immobilizer data Sanabria says.
