There is no standardized way to accomplish this, but it's important to plan out the way you'll route 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 the time to connect them to key switches. To do this you must place a diode on each pin on the key switch and solder it. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode permits current to only flow in only one direction. It is equipped with a visible indicator of a black line that shows the direction in which the current will flow.

Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY users in some cases program replacement keys and restore lost immobilizer data, Sanabria says.

Replacement case

Saab owners usually have only one car key, and if that is lost, they will be charged. The reason for this is that it's not inexpensive to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming.
