saab key programmer cars built since about 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. You should always keep a spare set of keys at hand.

Transponder key

The transponder is a key equipped with an electronic chip. This chip sends 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 match then the car will be able to open and start. This is a great method to prevent auto theft and keep your vehicle secure from thieves.

Transponder keys are a favored feature in cars, but it is important to know that they aren't as secure as traditional metal keys. While the metal portion of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code which is programmed into the car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has an unmodified chip and has been programmed to match. Otherwise, the car will refuse to accept the key and will not start.

This can be costly especially for used vehicles.

The next step is to wire the row and column wires to the microcontroller. This is the most tedious component of the project and will require a lot of soldering. There's no standard way to go about it, but you must think about how to open a saab 93 without a key to route and connect each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 5 rows and 17 columns.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, place an inverter over each key switch pin and then solder it. This will shield the pins from current and prevent 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 shows the direction in which current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep an item in their trunk to jump-start their vehicle in the event of an emergency, but it may not be the best option for vehicles with newer technology. These vehicles are equipped with numerous digital and computers that communicate with one another. A surge in voltage when a battery is hooked up to another one could damage these components and render your car undriveable.

Start the vehicle you are using and allow it to run for approximately two minutes before connecting the cables to the battery that is not working. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the damaged vehicle. The engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery, since it could ignite a spark that ignites the gasoline in the engine bay.

Once the cables are connected the disabled vehicle and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 will be recharged as you drive. It will take a while for it to recharge again. It is a good idea to purchase a spare fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and special programming to convince it that the lost keys aren't in the process of trying to steal the car.

Replacement Case
