Saab Key Programming

saab fob key replacement cars produced since 1994 feature an immobilizer system that relies on key codes. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key on hand.

Transponder key

The transponder is a key with an electronic chip. The chip sends a signal when the key is put into the ignition. The car checks to see whether the signal matches with the one on the key.

The chip has an unique code that is encoded into the car's system to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the fob has a non-modified chip that has been programmed to match. The car won't start if the key is not programmed to match.

There's no standard way to do this, but it's important to plan out the routes you'll use to solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It includes 5 rows and 17 column.

After the columns and rows are soldered together after which it is time to connect the key switches. To do this you must place a diode across each pin on the key switch and then solder it. This will shield the key switch pins from current and keep them from being shorted. A diode permits current to only flow in one direction. It has a visual indicator, a black band, that shows which way current will flow.

Sanabria states that some of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 can assist shoppers or DIY customers to program replacement keys and restore immobilizer information.
