Saab Key Programming
Saab cars made since 1994 use an immobilizer that relies on key codes. A new transponder is required in order to enable the addition of an additional key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
It can be costly. This is the reason why you should always have a spare key at hand.
Transponder key
The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to the car when it is inserted into the ignition. The car then checks to see whether the signal matches with the one on the key. If the signals match the car will then unlock itself and begin. This is a great way to deter car theft and keep your car safe from thieves.
Transponder keys are a common feature in automobiles, but it is important to know that they're not as secure as classic keys made of metal. The metal component of the traditional keys can be easily copied and cut, but transponders have an electronic chip which protects it. The chip has a unique code which is programmed into a car's computer 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 it is equipped with a chip that is unmodified and has been programmed to match. The car won't start in the event that the key has not been programmed to match.
It is important to have an extra Saab key. This is particularly true when you live in a rural region that has numerous car thieves. The good thing is that you can get a replacement key for your Saab without having to go to a dealer and pay the high costs they ask. You can have the replacement key on the spot at a fraction of the cost you would spend at an auto dealer.
Wired key
Saab cars are typically delivered with two keys. If you only own one, it is recommended to get an extra key as soon as you can. This is because if you lose it, the car will need an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're buying a used car.
The next step is to connect the wires for the column and row to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There's no standard way to accomplish this, but it is crucial to plan the way you'll route and solder the rows and columns. 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 joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from being shortened. A diode can only allow current to flow in one direction, and it also has a a black band visual indicator that indicates the direction in which current will flow.
Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in some cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the car's computer.

The majority of people have a set of jumper cables in their trunks for emergencies however, jumping a battery for newer vehicles might not be the most efficient option. These vehicles are equipped with many electronic devices and computers that communicate with one another. A surge of voltage when batteries are connected to another can fry the components and render your vehicle unusable.
Start the vehicle that is working and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the affected vehicle. The engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery, since it could ignite an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, start the car 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 will take a while for it to fall back. You should invest in a second key fob, when you can. Replacing the one that works requires the installation and programming of a brand new computer chip.
Replacement case
Saab owners usually only have one car key, and if that is lost, they'll be charged. The reason is that it's expensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a spare key in the event of theft or any other catastrophe, and the best way is to purchase an extra key as soon as you can. But don't buy a used key, even the case that it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't work and are likely to fail in the crucial moment.
The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a new key without the need to replace the entire system. This could save you a great deal of money. It's also cheaper than waiting until you lose your one key.
