saab car keys Key Programming

Saab cars that were built prior to 1994 come with an immobilizer system that is based on codes for keys. The addition of a key requires an entirely new transponder and programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

This can be expensive. It is recommended to always have an extra set of keys at hand.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is inserted into the ignition. The car then examines the signal to see if it matches the one that is in the key. If the signals are in sync, the car will unlock and begin. This is a great method to prevent car theft and keep your vehicle secure from thieves.

Transponder keys may be an extremely popular accessory for cars, but they're not as safe as traditional metal keys. While the metal component of a conventional key can be cut and copied, a transponder is protected by an electronic chip. This chip has a unique code programmed into the car's computers to identify it.

When a Saab 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 an unmodified chip and programmed to match. The car won't start in the event that the key is not programmed to match.

This can be costly especially if you're buying a used car.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard method to go about it, but you must think about how to route and connect each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It includes 5 rows and 17 column.

After the columns and rows are soldered together It is now time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and also prevent them from being shorted. A diode lets current only flow in one direction. It has a visual indicator of a black line that indicates the direction in which current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain cases create replacement keys and restore lost immobilizer data Sanabria says. The tools connect to OBD ports and guide the user through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery for newer cars might not be the best idea.

The black cable should not be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.
