Saab cars manufactured since 1994 come with an immobilizer system made up of coded keys. A new transponder is required in order to enable the addition of an extra key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
It can be costly. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder can be described as a key that is equipped with an electronic chip. The chip transmits a signal when the key is placed into the ignition. The car then checks to see if the signal matches the one on the key. If the signals match the car will then unlock and begin. This is a great method to avoid car theft and keep your vehicle secure from thieves.
Transponder keys could be a popular addition to automobiles, but they are not as safe as traditional metal keys. The metal component of the traditional keys can be easily cut or copied, while transponders have an electronic chip that protects it. This chip contains a unique code encoded into the car's system to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it will only do this if the key fob has an unmodified chip that has been programmed to match it. If not, the car will refuse to accept the key and will not start.
It's important to make sure that you have a spare key for your Saab. This is especially true when you live in a rural location that has numerous car thieves. You can get a new key for your

Key for Wired
saab key fob cars usually come with two keys when they are new. If you only have one, it is recommended to get an extra key as soon as you can. This is because if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used car.
The next step is to connect the row and column wires to the microcontroller. This is the most laborious aspect of the project and will require lots of soldering. There's no standard way to accomplish this, however it's important to plan out how you will route and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 5 rows and 17 column.
After the rows and column are soldered together It is now time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, and prevent them from being cut off. A diode lets current only flow in only one direction. It is equipped with a visible indicator, a black band, that shows the direction in which the current will flow.
A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY users in some cases programme replacement keys and recover lost immobilizer data, Sanabria says. The tools connect to OBD ports and guide the user through each step which makes the process much easier than replacing the vehicle's computer.
Jumpstarting the battery
Most people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery in newer cars might not be the best idea. These cars have a variety of electronic devices and computers that communicate with each other. A voltage spike when a battery is connected to another can fry the components making your car unusable.
Start the vehicle you are using and let it run for about two minutes before you connect the cables to the non-working one. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the vehicle's hood. An engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite the gasoline that is in the engine compartment.
Once the cables are connected, you need to start the vehicle and let it run about five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 is recharged as you drive. It may take a while it to recharge again. It's a good idea to buy a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't attempting to steal the car.
Replacement Case
saab 93 replacement key owners often only have one car key, and if that is
lost, they'll be charged. The reason is that it's costly to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's recommended to have a second key in the event of theft or other disaster the best solution is to buy an extra key as quickly as you can. Even when the key is "new", it will not function.
Most locksmiths can't help you with a single working key, and the dealer will charge you for the cost of replacing the computer in your car to create a
replacement saab key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This could save you lots of money. It's cheaper to do this instead of waiting until you lose the only key.
