The car will recognize the saab key programmer keyfob and permit it to be turned on. However, it will only do this if the key fob has an unmodified chip that has been programmed to match it. The car won't start in the event that the key is not programmed to match.

It's not a common way to do it, but you need to determine how to open a saab 93 without a key to route and connect each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It has five rows and 17 columns.

After the rows and column are soldered together after which it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode allows the current to flow in a single direction, and it also has a an indicator of black color that indicates the direction in which current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY customers in certain cases programme replacement keys and recover the lost immobilizer's data, Sanabria says.

Jump-starting the battery

A lot of people keep the set in their trunks to start a vehicle in an emergency, but it might not be the best idea for cars with more modern technology.

Replacement Case

Saab owners often only have one car key, and if that is lost, they will be charged. The reason is that it's expensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is best to have a spare key in case of theft or any other catastrophe, and the best way is to purchase an extra key as early as you can.
