Saab Key Programming

saab key replacement cars built from 1994 have an immobilizer system that is based on key codes. A new transponder is required to allow the addition of an extra key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this can be very expensive. This is 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 out a signal when the key is placed into the ignition. The car will then check the signal to see if it matches the one that is in the key. If both signals match, the car will unlock itself and begin. This is a great method to stop auto theft and keep your car safe from thieves.

While the metal portion of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code which is programmed into the car's computer in order 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 if the device has an unmodified chip and has been programmed to match. In the absence of that, the car will reject the key and not start.

The next step is connecting the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a large deal of soldering. There's no standard way to accomplish this, however it is crucial to plan how you will route and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect for this keyboard. It includes 5 rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins of the key switch from current and prevent them from being shorted. A diode can only allow the current to flow in a single direction, and it also has a an indicator of black color that indicates which way the current will flow.

Sanabria states that a number of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508 can assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the car's computer.

Jump starting the battery

Most people keep an item in their trunks to jump-start their car in case of emergency, but this might not be a good option for vehicles with newer technology.
