saab 93 key replacement cars made since 1994 utilize an immobilizer system that relies on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The problem is that this can be quite costly. This is why it is important to always have a spare key available.

Transponder key

The transponder keys are keys with an electronic chip that sends a signal back to the car when it is inserted into ignition.

There is no standardized way to accomplish this, however it is crucial to plan the way you'll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the rows and column are soldered together after which it is time to connect the key switches. To do this, you need to place a diode on each pin of the key switch and solder it. This will shield the pins from current and prevent them from getting shorted. The diode allows current to only flow in one direction. It has a visual indicator, a black band, that indicates the direction in which current will flow.

Sanabria says that some of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508, can help shoppers or DIY users to program replacement keys and restore immobilizer data.

Replacement case

Saab owners often only have one car key, and if that is lost, they'll be charged. The reason for this is that it's costly to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming.
