The chip has a unique code that is inserted into the car's computer in order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. However, it can only do this if the fob has a non-modified chip that has been programmed to match it. The car will not start in the event that the key has not been programmed to match.

There's no standard way to do it, but you must determine 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 pins and wires to connect.

After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from getting shorted. A diode lets current only flow in one direction. It features a visual indicator of a black line that indicates which direction current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can help shop customers or even DIY customers in certain cases create replacement keys and restore lost immobilizer information, Sanabria says.

Jump-starting the battery

A majority of people keep an item in their trunk to start a vehicle in an emergency, but this might not be the best option for vehicles with newer technology. These cars have a variety of digital and computer systems that communicate with each other. A voltage spike when a battery is hooked up to another one could damage the components and render your vehicle unable to drive.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the disabled vehicle. The engine block is a great choice. Do not connect the black cable to the negative terminal of the dead battery, since this could cause a spark that ignites the gasoline in the engine bay.
