It can be costly. Always keep a spare set of keys at hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is put into the ignition. The car then checks the signal to determine whether it is identical to the one in the key. If the signals are the same it will open itself and begin.

The metal component of a traditional keys can be easily cut and copied, whereas transponders have an electronic chip that safeguards it. This chip contains a unique code encoded into the car's system to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do this if your key fob has a non-modified chip that has been programmed to match it. In the absence of that, the car will reject the key and won't start.

A diode allows the flow of current to be in one direction, and it comes with a an indicator in black that indicates the direction in which current will flow.
