Transponder key

The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is put into the ignition.

For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from getting shorted. A diode lets current only flow in one direction. It features a visual indicator, a black band, that shows the direction in which the current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- may assist customers at the shop or DIY customers in some cases program replacement saab 9-3 key keys and restore lost immobilizer data Sanabria says.
