This is an excellent way to protect your vehicle from theft.

Transponder keys are an extremely popular accessory for cars, but they're not as secure as traditional metal keys.

There's no standard way to do this, but it is important to think about how you will route and solder the columns and rows. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, put a diode across each pin of the key switch and then solder it. This will shield the pins of the key switch from current and prevent them from being shorted. A diode lets current only flow in only one direction. It has a visual indicator with a black band that shows the direction in which the current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain instances programme replacement keys and recover the lost immobilizer's data, Sanabria says.

In the event of theft, or other catastrophe, it is best to have an extra key. Don't purchase a used key even if it's "new."
