There isn't a standard way to accomplish this, but it's important to plan out how you will route and 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.

After the columns and rows are soldered, it's the time to connect them to key switches. To do this, you need to place a diode across each key switch pin and then solder it. This will shield the pins on the key switch from current and keep them from being shorted. A diode permits current to only flow in one direction. It comes with a visual indicator with a black band that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY users in some cases replace keys in the program and restore lost immobilizer information, Sanabria says.
