It can be costly. Always keep an extra set of keys on hand.

Transponder key

The transponder can be described as a key equipped with an electronic chip. This chip sends out a signal when the key is put in the ignition.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this you must place a diode on each pin on the key switch and then solder it. This will protect the pins from current, and prevent them from being shorted. The diode allows current to only flow in only one direction. It is equipped with a visible indicator with a black band that indicates the direction in which current will flow.
