Transponder key

The transponder key is a key with an electronic chip that sends a signal back to the car when it is put into the ignition.

There's no standard way to accomplish this, however it is important to think about the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and also prevent them from being shorted. A diode allows current to flow in one direction, and has a the black band as a visual indicator that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY users in some cases programme replacement keys and recover lost immobilizer information, Sanabria says.
