Saab Key Programming
Saab cars manufactured since 1994 utilize an immobilizer system based on coded keys. In order to add a second key, it requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
The issue is that this could be very expensive. This is the reason why you should always have a spare key at hand.
Transponder key
The transponder is a key that has an electronic chip. This chip sends a signal when the key is put into the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match then the car will be able to open and start. This is a great method to protect your vehicle from theft.
Transponder keys are a popular feature in vehicles, but you must be aware that they're not as secure as traditional metal keys. The metal part of the traditional keys can be easily cut or copied, while a transponder has an electronic chip which protects it. The chip is equipped with an individual code that is programmed into the car's computers to identify it.
The car will recognize the
saab 9-3 key not accepted contact service keyfob, and allow it to be turned on. The car can only recognize the key fob if it is equipped with an unmodified chip 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 vital to have a spare

Wired key
Saab cars are usually provided with two keys. If you have only one, it is recommended to purchase an extra key fob as quickly as you can, because if you lose it the car will require the replacement of a CIM unit and the locking cylinders have to be replaced. This can be costly particularly if you are buying a used car.
The next step is connecting the wires for columns and row to your microcontroller. This is the toughest part of the project, and it will require a lot of soldering. There is no standardized way to do this, but it is essential to determine how you will route and solder the columns and rows. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are joined It is now time to connect the key switches. To do this you must place a diode across each key switch pin and solder it. This will shield the pins on the key switch from current and also prevent them from being shorted. The diode will only allow the current to flow in a single direction, and it has the black band as a visual indicator 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 -- may assist customers at the shop or DIY customers in certain cases program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the user through each step making the process simpler than replacing the car's computer.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunk for emergency situations however, jumping a battery on modern automobiles might not be the best choice. These cars are equipped with a variety of computers and digital devices which communicate with one another. A surge of voltage when the battery is connected another can fry the components making your car inoperable.
Connect the cables to the vehicle that is operating. Allow it to run for two minutes. 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 under the hood of the affected car. The engine block is a great option. Do not connect the black cable to the negative terminal of the dead battery because it could spark an ignition source that ignites gasoline in the engine bay.
After the cables have been connected, you need to start the vehicle and let it run for approximately five minutes. Then, disconnect them in reverse. Be aware that the battery in the

It is a good idea to purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and special programming to convince it that your missing keys are not trying to steal the car.
Replacement case
Many
saab 93 key programming owners have only one key for their vehicle and if they lose it, the cost will be. It's expensive to buy 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 catastrophe it is recommended to have a spare key.

The majority of locksmiths won't be able to help when you only have one working key and the dealer will charge for the cost of replacing the computer in your car to create a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a replacement key without having to replace the entire system. This can save you a lot of money. It's also a lot cheaper than waiting until you lose your one key.
