Saab Key Programming

saab key fob programming cars that were built prior to 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required to allow the addition of an extra key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that this could be extremely expensive. Always keep an extra set of keys available.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car then analyzes the signal to determine whether it matches that of the key. If the signals are the same it will open itself and start. This is a great method to stop car theft and keep your vehicle secure from thieves.

Transponder keys may be an extremely popular accessory for automobiles, but they are not as secure as traditional keys made of metal. While the metal part of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip has an unique code that is embedded into the car's computer to identify it.

The car will recognize the Saab keyfob and permit it to turn on. But, it's only able to do so if the key fob has an unmodified chip that has been programmed to match it. Otherwise, the car would reject the key and refuse to start.

It's not a common way to go about it, but you need to plan how to route and solder each column and SAAB Replacement Key row. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 columns.

After the columns and rows are soldered together, it is time to connect the key switches. To do this, put a diode on each key switch pin and solder it. This will protect the pins of the key switch from current and keep them from being shorted. A diode can only allow the current to flow in a single direction, and it also has a a black band visual indicator that indicates the direction current will flow.

Sanabria says that a few of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 are able to assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a set in their trunk to jump-start their vehicle in an 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 is not to be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline that is in the engine compartment.

Once the cables are connected, you can start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will recharge while you drive. It takes a while for it to recharge again. It is a good idea to purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a new computer module and a special program to convince the system that your lost keys aren't trying to steal the car.

Replacement case
