Saab cars manufactured since 1994 have an immobilizer feature that is based on codes for keys. A new transponder is required for addition of an additional key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
It can be costly. This is the reason why you should always keep a spare key in your possession.
Transponder key
The transponder key is a piece of hardware with an electronic chip that sends a signal to the car when it is inserted into ignition. The car will then check the signal to determine whether it is identical to the one on the key. If the signals match then the car will be able to unlock and begin. This is a great way to stop auto theft and keep your vehicle secure from thieves.
Transponder keys are a common feature in vehicles, but you must be aware that they are not as secure as traditional keys made of metal. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. The chip has an individual code that is programmed into the car's computers to identify it.
The car will recognize the Saab keyfob and allow it to be turned on. However, it can only do this if the key fob is equipped with a chip that is not modified that has been programmed to match. The car will not start in the event that the key has not been programmed to match.

There's no standard way to go about it, but you must consider how you will route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.
After the rows and column are soldered together It is now time to connect the key switches. To do this, put a diode across each pin of the key switch and solder it. This will shield the pins of the key switch from current and also prevent them from being shorted. The diode will only allow current to flow in one direction, and it also has a a black band visual indicator that indicates which way the current will flow.
Sanabria says that a few of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY users to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle'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 in newer vehicles may not be the most efficient option.

Attach the other end to a clean, unpainted metal surface under the hood of the affected vehicle. The engine block is an excellent option. Don't connect the black cable to the negative terminal on the dead battery, since it could ignite an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, turn on the disabled vehicle and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in your Saab 9-3 will recharge while you drive. It takes a while for it to return to its original state. It's a good idea purchase a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and special programming to convince it that the lost keys aren't in the process of trying to steal the car.
Replacement case
Saab owners typically only have one car key, and if that is lost, they'll be charged. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE for older models. It is best to have a second key in the event of theft or any other catastrophe, and the best way is to purchase an additional key as early as you can. But saab key programming near me G28 buy a used key even when it's "new." Keys that are claimed as new from aftermarket sellers will not work and are likely to fail in the crucial moment.
