The problem is that this can be quite costly. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a key that is equipped with an electronic chip. This chip sends a signal when the key is put in the ignition. The car then checks the signal to see whether it matches the one on the key. If the signals match, the car will unlock and begin. This is a great way to avoid car theft and keep your vehicle safe from thieves.

Transponder keys are an increasingly popular feature in automobiles, but you should be aware they aren't as secure as traditional keys made of metal. The metal component of the traditional key can be easily cut and copied, whereas transponders are protected by an electronic chip that safeguards it. This chip contains an individual code that is programmed into the car's computer to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and programmed to match. The car will not start in the event that the key is not programmed to match.

It's not a standard way to do it, but you need to think about how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are joined It is now time to connect the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will shield the key switch pins from current and prevent them from being shorted. A diode permits current to only flow in one direction. It has a visual indicator of a black line that shows the direction in which the current will flow.

Jump-starting the battery

A majority of people keep an item in their trunk to start a car in case of emergency, however it might not be a good option for vehicles with newer technology. These vehicles are equipped with a number of computers and digital devices that communicate with each other. A voltage spike when the battery is connected to another one could damage these components and render your car undriveable.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say ”POS” or ”+”.) Attach the other end to a clear, unpainted metal surface beneath the hood of the damaged vehicle. The engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks that could ignite the gasoline inside the engine compartment.

Once the cables are connected, you can start the vehicle that is disabled and allow it to run for around five minutes before you disconnect them in reverse order.

Replacement Case

Saab owners usually have only one car key, and if that is lost, they'll be charged. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster it is best to have an extra key. Even when the key is ”new” it won't work.

Most locksmiths can't help you when you only have one working key and the dealer will charge for the cost of replacing the computer in your car to create a replacement. We can, however, reset and re-program the computer's EEPROM to accept an alternative key without replacing the entire system. This could save you lots of money. It's much cheaper than waiting until you loose the only key.
