Saab Key Programming

Saab cars built since 1994 utilize an immobilizer that relies on key codes. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

If the signals match the car will then open and start. This is an excellent way to safeguard your car from theft.

Transponder keys could be an increasingly popular feature for cars, but they're not as safe as traditional metal keys. The metal component of the traditional keys can be easily copied and cut, but transponders are protected by an electronic chip which protects it. This chip contains an unique code that is programmed into a car's computers in order to identify it.

The car will recognize the saab Ignition Key replacement keyfob, and allow it to be turned on. But, it's only able to do this if the fob is unmodified and has a chip that has been programmed to match. The car won't start when the key isn't programmed to match.

There's no standard way to accomplish this, however it is important to think about the routes you'll use to solder the columns and rows. There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 column.

After the columns and rows are soldered, it's time to connect them to key switches. To do this, place a diode over each pin of the key switch and solder it. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode allows the flow of current to be in one direction, and it also has a an indicator in black that indicates which way the current will flow.

Sanabria states that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 are able to assist shoppers or DIY users to program replacement keys and restore data from the immobilizer.
