Saab cars made since 1994 utilize an immobilizer system that is based on a set of keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
This can be expensive. It is recommended to always have an extra set of keys at hand.
Transponder key
The transponder keys are keys equipped with an electronic chip. It sends a signal back to the car when it is put into the ignition. The car then examines the signal to determine whether it is the same as the one in the key. If the signals are in sync then the car will be able to unlock and begin. This is a great method to safeguard your car from theft.
Transponder keys are a popular feature in automobiles, however you should be aware they aren't as secure as traditional keys made of metal. While the metal parts of a traditional key can be cut and copied the transponder is protected by an electronic chip. This chip contains an unique code which is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. But, it's only able to do this if the fob has an unmodified chip that has been programmed to match it. If not, the car will reject the key and not start.
It is essential to have a spare Saab key. This is particularly important when you live in a rural location that has many car thieves. The good thing is that you can find a new key for your Saab without needing to visit a dealer and pay the expensive prices that they demand. In the majority of instances, you can get a brand new key made right on the spot for less than half the price of what you'd pay at the dealer.
Wired key
Saab cars usually come with two keys when they are new. If you have only one, it is recommended to purchase an extra key fob as soon as is possible, because if you lose it, the car will require a new CIM unit and the locking cylinders need to be replaced. This can be expensive especially for used vehicles.
The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and will require a great deal of soldering. There isn't a standard method to go about it, but you need to plan how to open a saab 93 without a key to route and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.
Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins that are used for key switches from current and prevent them from being shorted. A diode permits current to only flow in only one direction. It comes with a visual indicator with a black band that indicates the direction in which current will flow.
Some of the tools offered at auto parts stores – such as the Autel MaxiIM IM608 PRO and IM508 – may help shop customers or even DIY customers in certain instances programme replacement saab 9-3 key keys and recover lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunks in case of emergency, but jumping a battery on modern automobiles might not be the best option. These vehicles are equipped with numerous digital and computers that communicate with each other. A voltage surge when batteries are connected to another could cause damage to the components, rendering your car undriveable.
Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal on the battery that is good (it will have “POS” or “+” on it). Attach the other end to a clean unpainted metal surface beneath the hood of the disabled vehicle. The engine block is an excellent option. Do not connect the black cable to the negative terminal of the dead battery, since this could trigger an ignition that ignites the gasoline in the engine bay.
Once the cables are connected the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. Remember that the battery on the Saab 9-3 will be charged while you drive, so it will take a while to get the battery back to normal. It is recommended to purchase another key fob when you can. Replacing the one that works requires the installation and programming of a brand new computer chip.
Many saab 93 key programming owners only have one key for their vehicle and if they lose it, they'll be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft, or any other catastrophe it is advisable to have a spare key. However, don't purchase a secondhand key, even when it's “new.” Keys that are claimed as new from sellers selling aftermarket keys won't perform and are almost certain to fail in the crucial moment.

We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept the new key without having to replace the entire system. This can save you a lot of money. It's also cheaper than waiting until you lose your one key.
