Saab Key Programming
saab 93 key cars built since about 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required for addition of a second key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
This can be expensive. It is recommended to always have a spare set of keys in your possession.
Transponder key
The transponder key is a key with an electronic chip that transmits a signal to the car when it is put into the ignition. The car then checks the signal to see 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.

This chip contains a unique code that is embedded into the car's computer to identify it.
The car will recognize the saab 93 key replacement keyfob and permit it to be turned on. But, it's only able to do so if the key fob is equipped with a chip that is not modified that has been programmed to match. The car will not start in the event that the key has not been programmed to match.
It is important to have an extra Saab key. This is particularly important when you live in a rural region where there are a lot of car burglars.

The next step is to connect the wires of columns and row to your microcontroller. This is the most tedious part of the project, and will require a lot of soldering. There is no standardized way to accomplish this, however it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins to connect for this keyboard. It has five rows and 17 columns.
After the columns and rows 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 on the key switch from current and keep them from being shorted. A diode only allows the flow of current to be in one direction, and it also has a a black band visual indicator that indicates the direction in which current will flow.
Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- can help shop customers or even DIY customers in certain cases programme replacement keys and recover the lost Saab keys immobilizer's data, Sanabria says. The tools plug into OBD ports and help the customer 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 emergencies, but jumping a battery in newer cars might not be the best choice. These vehicles have many computers and digital devices that communicate with each other. A surge of voltage when the battery is connected to another battery could damage the components and render your vehicle unusable.
Start the vehicle that is working and let it run for about two minutes before you connect the cables to the non-working one. 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 clear, unpainted metal surface under the hood of the affected car. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery as this could trigger an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, you should start the vehicle and let it run for approximately five minutes. Then disconnect them in reverse. Be aware that the battery of your saab key programmer 9-3 is recharged when you drive, so it will take a while how to open a saab 93 without a key get the battery down. It is a good idea to buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming to convince it that your lost keys are not trying to steal the car.
Replacement case
Saab owners often only have one car key, and if it is lost, they'll be charged. The reason is that it's not inexpensive to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other calamity it is best to have an extra key. However, don't purchase a secondhand key even when it's "new." Claimed-new keys from aftermarket sellers will not perform and are almost certain to fail at the crucial moment.
The dealer will charge you the most expensive dollar if you have only one working key. However, we can reset and re-program your computer's EEPROM to prepare it to accept the new key, without replacing the whole system. That can save you lots of money. It's cheaper to do this than waiting until you lose the sole key.
