Saab Key Programming

Transponder key

The transponder key is a key equipped with an electronic chip. It transmits a signal to the car when it is put into the ignition. The car then analyzes the signal to determine whether it is the same as the one that is in the key. If the signals are the same the car will then unlock itself and begin.

There's no standard way to do it, but you need to think about how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered together It is now time to connect the key switches. To do this, place a diode on each pin on the key switch and then solder it. This will shield the key switch pins from current and also prevent them from being shorted. A diode only allows the flow of current to be in one direction, and it has an indicator of black color that shows the direction in which current will flow.

Sanabria states that a number of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 are able to assist customers shopping or DIY customers to program replacement keys and restore the immobilizer's data.

Remember that the battery on your Saab 9-3 is charged while you drive, so it could take a while to get the battery back to its original level.

Replacement Case

saab 900 key owners typically only have one car key, and if it is Lost saab Keys, they will be charged.
