The transponder key is a key equipped with an electronic chip. It sends a signal to car when it is inserted into the ignition. The car then examines the signal to see if it matches that of the key. If the signals match the car will then unlock and begin. This is a great way to avoid auto theft and keep your car safe from thieves.

Transponder keys could be an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. The metal component of the traditional keys can be easily cut and copied, whereas a transponder has an electronic chip which protects it. The chip has a unique code embedded into the car's computer to identify it.

The car will recognize the Saab keyfob and allow it to be turned on. However, it can only do this if the fob has an unmodified chip that has been programmed to match it. Otherwise, the car will reject the key and refuse to start.

There isn't a standard way to accomplish this, but it is crucial to plan the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

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

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

Jump starting the battery
