Transponder keys may be an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal.

It has five rows and 17 column.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins on the key switch from current and stop them from being shorted. The diode allows current to only flow in one direction. It is equipped with a visible indicator with a black band that shows which way current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY users in some cases create replacement keys and restore lost immobilizer information, Sanabria says.
