Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is put into the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are the same it will open itself and begin. This is a great way to protect your car from theft.

Transponder keys are a favored feature in automobiles, however it is important to know that they are not as secure as classic keys made of metal. While the metal parts of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip is equipped with a unique code programmed into the car's computer to identify it.

When a saab ignition key key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car won't start in the event that the key has not been programmed to match.

The next step is connecting the wires of columns and row to your microcontroller. This is the toughest part of the project and it will require lots of soldering. There isn't a standard way to do this, but it's important to plan out how you will route and solder the rows and columns. 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 joined then it's time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins of the key switch from current and keep them from being shorted. A diode allows current to only flow in only one direction. It has a visual indicator of a black line 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 -- may assist customers at the shop or DIY users in some cases program replacement keys and restore lost immobilizer data Sanabria says.

Jumpstarting the battery

The majority of people have the set in their trunk to jump start a car in case of emergency, but it might not be a good idea for vehicles that are newer. These vehicles are equipped with electronic devices and computers that communicate with each other. A surge in voltage while a battery is hooked up to another one could damage these components and render your vehicle undriveable.

Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of the affected vehicle. The engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery because this could trigger a spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle that is disabled and let it run for approximately five minutes before you disconnect them in reverse order. Keep in mind that the battery on the Saab 9-3 will be charged while you drive, so it may take some time to get the battery back to normal.

Most locksmiths can't help you in the event that you only have one working key and the dealer will charge top dollar to replace the computer in your vehicle to make a replacement. We can, however, reset and re-program the computer's EEPROM to accept a new key without replacing the whole system. This could save you a lot of money.
