Saab Key Programming

saab 93 key cars built since 1994 utilize an immobilizer system that relies on key codes. A new transponder is required to allow the addition of a second key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key available.

Transponder key

The transponder is a piece of key with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car is able to check if the signal matches the one on the key. If both signals match the car will then unlock itself and begin. This is a great method to deter auto theft and keep your vehicle secure from thieves.

While the metal part of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code that is programmed into the car's computer in order to identify it.

The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There isn't a standard method to go about it, but you need to think about how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, place a diode over each pin of the key switch and then solder it. This will shield the pins from current, and prevent them from being shortened. A diode only allows the current to flow in a single direction, and has a the black band as a visual indicator saab ignition Key that shows the direction in which current will flow.

Sanabria states that some of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data.

Jump starting the battery

A majority of people keep an item in their trunk to start a car in case of emergency, but it might not be the best idea for cars with more modern technology.

The engine block is a good alternative. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline inside the engine compartment.

After the cables have been connected, you need to begin the car and let it run about five minutes. Then, disconnect them in reverse.
