Transponder keys could be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal part of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip is a unique code that's 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 will only recognize the key fob if it has an unmodified chip and has been programmed to match. The car won't start when the key isn't programmed to match.

There isn't a standard method to do it, but you must think about how to open a saab 93 without a key to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this, put a diode across each pin of the key switch and then solder it. This will shield the pins from current, and prevent them from being shortened. A diode allows current to only flow in one direction. It features a visual indicator that is black, that indicates which direction current will flow.

Sanabria says that some of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data.
