After the columns and rows are soldered together after which it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, and prevent them from being shorted. The diode will only allow the current to flow in a single direction, and it comes with a a black band visual indicator that indicates the direction current will flow.

Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY customers in certain cases programme replacement keys and recover lost immobilizer information, Sanabria says.

Replacement Case

Many Saab owners have only one key for their car and if they lose it, it's going to cost them. The reason for this is that it's expensive to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's recommended to have a second key in the event of theft or any other catastrophe and the most effective way is to purchase an extra key as quickly as you can.
