Saab Key Programming

Saab cars made since 1994 have an immobilizer system based on coded keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

Transponder key

The transponder can be described as a key that has an electronic chip. This chip sends out a signal when the key is inserted in the ignition.

This chip contains a unique code that is programmed into the car's computers to identify it.

The car will recognize the saab replacement keys keyfob and allow it to turn on. But, it's only able to do this if the key fob has an unmodified chip that has been programmed to match. The car won't start in the event that the key has not been programmed to match.

There is no standard method to do this, but it is crucial to plan the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this, place an inverter over each key switch pin and solder it. This will protect the pins on the key switch from current and stop them from being shorted. A diode allows current to only flow in one direction. It has a visual indicator, a black band, that shows the direction in which the current will flow.

Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 will assist shoppers or DIY users to program replacement keys and restore immobilizer data.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery on modern vehicles might not be the best option.

Replacement case

Many saab 9 3 key replacement owners only have one key for their vehicle and if they lose that the cost will be. The reason for this is that it's costly to replace a key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming.
