saab spare key Key Programmingsaab key programmer cars built since 1994 feature an immobilizer that relies on coded keys. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The problem is that it can be very expensive. It is recommended to always have an extra set of keys at hand.
Transponder key
The transponder is a piece of key equipped with an electronic chip. The chip sends a signal when the key is put in the ignition. The car will then check the signal to determine whether it is the same as the one in the key. If the signals match it will open itself and start. This is a great method to guard your car against theft.
Transponder keys are a popular feature in automobiles, however you should be aware that they are not as secure as traditional metal keys. While the metal parts of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code that is inserted into a car's computer order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it can only do so if the key fob is unmodified and has a chip that has been programmed to match it. In the absence of that, the car will reject the key and refuse to start.
It is important to have an extra Saab key. This is especially true for those who live in a rural location where there are many car thieves. The good part is that you can get a replacement key for your Saab without needing to visit an auto dealership and pay the hefty prices they ask.

This can be expensive especially for cars that are used.
The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult aspect of the project and will require lots of soldering. It's not a common way to go about it, but you should consider how you will connect and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It includes 5 rows and 17 columns.
Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from being shorted. A diode allows the flow of current to be in one direction, and it also has a an indicator in black that indicates the direction current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY users in some cases program replacement keys and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunk for emergencies, but jumping a battery in newer vehicles might not be the best option. These vehicles are equipped with digital and computer systems that communicate with one another. A surge in voltage when the battery is connected to another can fry the components making your car unusable.
Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of the affected vehicle. The engine block is an excellent option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline inside the engine compartment.
Once the cables are connected, begin the car and let it run for about five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It will take a while for it to drop back down. It is recommended to purchase a second key fob, as soon as possible. The replacement of the one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Saab owners usually have only one car key, and if that is lost, they will be charged. It's costly to add the key and also requires replacing the CIM or TWICE for older models. It is best to have a second key in case of theft or other disaster the best solution is to purchase a second key as soon as you are able to. Even when the key is "new" it won't work.
The dealer will charge you the highest dollars if you only have one working key. However, we can reset and re-program your computer's EEPROM to prepare it to accept a new key without replacing the entire system. This can save you lots of money. It's also much less expensive than waiting until you lose your only key.
