This is an excellent way to guard your car against theft.

Transponder keys are an increasingly popular feature for cars, but they're not as safe as traditional metal keys.

There's no standard way to go about it, but you should think about how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the key switch pins from current and stop them from being shorted. A diode can only allow current to flow in one direction, and it comes with a the black band as a visual indicator that indicates the direction in which current will flow.

A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY customers in certain cases create replacement keys and restore the lost immobilizer's data, Sanabria says.

Jump starting the battery

A lot of people keep an item in their trunks to jump-start their vehicle in the event of an emergency, but it may not be the best option for vehicles with newer technology.

Don't connect the black cable to the negative terminal of the dead battery, since it could spark an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the disabled vehicle and let it run for about five minutes before disconnecting them in reverse order.

The reason for this is that it's not inexpensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other catastrophe it is advisable to have an extra key. But don't buy a used key, even if it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't perform and are almost certain to fail at the crucial moment.
