saab car keys Key Programming

Saab cars made since 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required to allow the addition of an additional key, as well as special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

This can be expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal back to the car when it is placed in the ignition. The car then checks the signal to see whether it is the same as the one on the key. If the signals are identical it will open itself and begin. This is a fantastic way to guard your car against theft.

Transponder keys are a popular addition to cars, but they're not as secure as traditional metal keys. 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 that is encoded into the car's system 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 your key fob has an unmodified chip that has been programmed to match the original. The car won't start when the key isn't programmed to match.

This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most laborious component of the project and it will require a lot of soldering.

It has five rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins on the key switch from current and keep them from being shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator with a black band that shows which way current will flow.

Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY users in some cases program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the car's computer.

Jump starting the battery

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.

In the event of theft or any other calamity it is recommended to have a spare key. Don't buy a secondhand key even it's "new."
