saab 93 key fob replacement cars produced since 1994 use an immobilizer system that is based on a set of keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. It is recommended to always have a spare set of keys on hand.

Transponder key

The transponder is a key equipped with an electronic chip. The chip transmits a signal when the key is inserted in the ignition. The car then analyzes the signal to determine whether it is the same as that of the key. If the signals match then the car will be able to unlock and start.

There is no standard method to do this, but it is crucial to plan the routes you'll use to solder the rows and columns. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 column.

After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, preventing them from being shortened. The diode will only allow current to flow in one direction, and it also has a an indicator in black that shows the direction in which current will flow.

Sanabria says that a few of the tools sold in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 will assist customers shopping or DIY customers to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the user through the procedure, making it simpler than replacing the computer in the vehicle.

Jump-starting the battery

A majority of people keep a set in their trunk to jump start a car in case of emergency, but it might not be a good idea for newer cars. These vehicles have many computers and digital devices that communicate with one another. A surge in voltage when a battery is connected to another can fry the components making your car unusable.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clear, unpainted metal surface beneath the hood of the damaged car. The engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline inside the engine compartment.

After the cables have been connected, you can start the car and allow it to run for around five minutes. Then, disconnect the cables in reverse.

Replacement Case

It's recommended to have a second key in case of theft or any other catastrophe and the most effective way is to purchase a second key as soon as you can. Even when the key is "new" it will not work.
