The transponder is a key with an electronic chip. This chip sends out a signal when the key is inserted in the ignition. The car will then check the signal to see whether it is identical to the one on the key. If the signals match, the car will unlock itself and begin.

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

There is no standardized way to accomplish this, but it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has 5 rows and 17 columns.

After the rows and column are joined, it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being cut off.

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

Jump-starting the battery

Most people keep an item in their trunks to jump-start a car in an emergency, but this might not be the best idea for cars with more modern technology. These cars are equipped with 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 these components and render your vehicle unable to drive.

Start the vehicle you are using and let it run for about two minutes before connecting the cables to the one that is disabled. Attach the red clip on 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 good choice. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline in the engine compartment.

Once the cables are connected, turn on the vehicle that has been disabled and let it run for about five minutes before you disconnect them in reverse order. Remember that the battery on the Saab 9-3 gets recharged during your drive, which means it can take a while to get the battery back to normal.

Most locksmiths cannot help you in the event that you only have one working key and the dealer will charge high fees to replace the computer in your car to make a replacement. We can, however, reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This could save you a significant amount of money.
