Saab Key ProgrammingSaab cars manufactured since 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required in order to enable the addition of an extra key, and special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
It can be costly. This is why you should always have a spare key at hand.
Transponder key
The transponder keys are keys with an electronic chip that sends a signal to car when it is put into the ignition. The car will check to see whether the signal matches with the one on the key. If the signals are in sync, the car will unlock and begin. This is a great method to avoid car theft and keep your car secure from thieves.
Transponder keys are a favored feature in vehicles, but you should be aware that they're not as secure as traditional keys made of metal. The metal component of the traditional key is easily copied and cut, but a transponder has an electronic chip which protects it. The chip is equipped with a unique code programmed into the car's computers to identify it.
When a
saab centre milton keynes key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob when it has an unmodified chip and programmed to match. The car won't start if the key is not programmed to match.
It is essential to have an extra

The good news is that it's possible to get a replacement key for your Saab without needing to visit an auto dealership and pay the hefty prices that they charge. You can get the replacement key on the spot for less than half the cost you would spend at the dealership.
Key for Wired
saab 93 key fob cars are usually provided with two keys. If you have only one, you should get an extra key as soon as you can. This is because, if it's lost, the car will need an entirely new CIM and the locking cylinders replaced. This can be costly especially if buying a used car.
The next step is to connect the row and columns wires to your microcontroller. This is the most laborious aspect of the project and it will require a lot of soldering. It's not a standard way to do it, but you must consider how you will connect and solder 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 joined after which it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, preventing them from being shortened. The diode allows current to only flow in one direction. It features a visual indicator, a black band, that indicates which direction current will flow.
Sanabria says that a few of the tools that are sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 can assist shoppers or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer in the vehicle.
Jump-starting the battery
Most people keep a few sets of jumper cables in their trunks in case of emergency however, jumping a battery on newer vehicles might not be the best idea. These cars have a variety of electronic devices and computers that communicate with each other. A voltage surge while a battery is hooked up to another one could damage these components, rendering your car undriveable.
Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood--the engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite the gasoline inside the engine compartment.
Once the cables are connected, start the disabled vehicle and let it run for approximately five minutes before you disconnect them in reverse order. Keep in mind that the battery on the Saab 9-3 gets recharged during your drive, which means it may take some time for the battery to go down. It's a good idea purchase a spare fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and a special program to convince it that your lost keys are not trying to steal the car.
Replacement case
saab 93 key owners often only have one car key, and if it is lost, they will be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster it is best to have a spare key. Even if the key is "new" it will not work.
Most locksmiths aren't able to help with a single working key and the dealer will charge you for the cost of replacing the computer in your vehicle to make a replacement. We can, however, reset and reprogram the computer's EEPROM in order to prepare it to accept the new key, without replacing the whole system. This can help you save money. It's much cheaper instead of waiting until you loose the only key.
