Saab Key Programming

Saab cars that were built prior to 1994 feature an immobilizer mechanism based on coded keys. Adding an extra key requires a new transponder and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

Transponder keys could be an increasingly popular feature for automobiles, but they are not as safe as traditional keys made of metal. While the metal portion of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. The chip has a unique code that is inserted into the car's computer in order to identify it.

When a saab ignition key key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the fob has an unmodified chip that has been programmed to match the original. If not, the car will refuse to accept the key and will not start.

It's not a common way to do it, but you must think about how to 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 columns.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this you must place a diode on each key switch pin and then solder it. This will shield the pins from current, and prevent them from getting shorted. A diode can only allow the flow of current to be in one direction, and it comes with a a black band visual indicator that indicates which way the current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement key for saab 93 keys and restore data from the immobilizer.

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

The battery in the saab 9 3 key replacement 9-3 will charge as you drive. It may take a while it to drop back down. It is recommended to purchase an additional key fob as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip.

In the event of theft or any other catastrophe it is advisable to have a spare key. But don't buy a used key even the case that it's "new."
