Saab cars built since about 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required in order to enable the addition of an extra key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The transponder can be described as a key that is equipped with an electronic chip. The chip transmits a signal when the key is inserted in the ignition.

This is a great method to avoid auto theft and keep your car secure from thieves.

Transponder keys are a common feature in automobiles, but you should be aware that they aren't as secure as classic keys made of metal. While the metal parts of a conventional key can be cut and copied, a transponder is protected by an electronic chip. The chip has a unique code that is embedded into the car's computer to identify it.

There isn't a standard method to go about it, but you need to think about how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this you must place an inverter over each pin on the key switch and solder it. This will shield the pins on the key switch from current and also prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it also has a the black band as a visual indicator that shows the direction in which current will flow.

Sanabria says that a few of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 can assist customers shopping or DIY customers to program replacement keys and restore immobilizer information. The tools plug into the OBD port and guide the user through the process, making it easier than replacing the computer in the vehicle.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunks to use in an emergency however, jumping a battery on newer cars might not be the best idea.

The black cable should not be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite the gasoline inside the engine compartment.

The battery in your saab key replacement cost 9-3 is recharged while you drive. It may take a while it to drop back down. You should purchase another key fob as soon as you can.

It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It's recommended to have a spare key in the event of theft or any other catastrophe the best solution is to buy an extra key as soon as you are able to. But don't buy a used key, even it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't perform and are almost certain to fail at the critical moment.

Most locksmiths aren't able to help if you have only one working key and the dealer will charge you top dollar to replace the computer in your vehicle for a replacement.
