Saab cars built since about 1994 have an immobilizer feature that is based on codes for keys. The addition of a key requires an entirely new transponder and programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

This can be expensive. Always keep a spare set of keys at hand.

Transponder key

The transponder is a key that is equipped with an electronic chip. This chip sends out a signal when the key is inserted in the ignition. The car then analyzes the signal to determine if it matches the one that is in the key. If the signals are in sync then the car will be able to open and start. This is a great method to prevent auto theft and keep your vehicle safe from thieves.

This chip contains an unique code which is programmed into a car's computer in order to identify it.

When a saab key fob repair key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and programmed to match. Otherwise, the car will reject the key and refuse to start.

The next step is to connect the wires for the column and row to the microcontroller. This is the most tedious aspect of the project and it will require a lot of soldering. There isn't a standard method to go about it, but you must consider how you will route and connect each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 column.

After the rows and column are joined It is now time to connect the key switches. To do this, you need to place a diode over each key switch pin and then solder it. This will shield the key switch pins from current and stop them from being shorted. A diode can only allow current to flow in one direction, and it also has a an indicator of black color that indicates which way the current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain instances program replacement keys and restore lost immobilizer data Sanabria says.

Jump-starting the battery

The majority of people have the set in their trunks to jump start a vehicle in the event of an emergency, but it may not be a good option for vehicles with newer technology.

Do not connect the black cable to the negative terminal of the dead battery, since it could ignite an ignition spark that ignites the gasoline in the engine bay.

The reason for this is that it's not inexpensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or other catastrophe, it is best to have an extra key. But don't buy a used key even if it's "new." Claimed-new keys purchased from third-party sellers won't work and are almost guaranteed to fail at the crucial moment.
