Saab Key Programming
Saab cars made since 1994 come with an immobilizer system that is based on codes for keys. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
This can be expensive. You should always keep a spare set of keys at hand.
Transponder key
The transponder key comes equipped with an electronic chip. It transmits a signal to the car when it is put into the ignition. The car then examines the signal to determine whether it matches the one that is in the key. If the signals match, the car will open and start. This is a great way to protect your vehicle from theft.
Transponder keys are an extremely popular accessory for automobiles, but they are not as safe as traditional metal keys. While the metal part of a traditional key could be cut and copied, a transponder is protected by an electronic chip. This chip has an unique code that is encoded into the car's system to identify it.
When a saab 9-3 key not accepted contact service key fob is used, the car recognizes it and allows it to turn on. The car will only recognize the key fob if it has an unmodified chip and has been programmed to match. The car won't start when the key isn't programmed to match.
It is crucial to have an extra Saab key. This is especially true for those who live in a rural area with numerous car thieves.

Key for Wired
saab 900 key cars usually come with two keys when they're new. If you own only one, you should get an additional key as fast as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This could be expensive 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 will require a lot of soldering. There isn't a standard way to accomplish this, but it is essential to determine the routes you'll use to solder the columns and rows. There are 22 microcontroller wires and pins to connect to this keyboard. It has five rows and 17 columns.
After the columns and rows are soldered together It is now time to connect the 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 current to only flow in one direction. It is equipped with a visible indicator with a black band that indicates which direction current will flow.
Sanabria states that a number of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 will assist shoppers or DIY users to program replacement keys and restore data from the immobilizer. The tools plug into the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.
Jumpstarting the battery
The majority of people have a set in their trunks to jump-start a car in an emergency, but it may not be the best idea for newer cars. These vehicles are equipped with numerous digital and computer systems that communicate with one another. A voltage surge when batteries are connected to another can fry the components making your car unusable.
Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface under the hood of the damaged car. The engine block is an excellent alternative. Don't connect the black cable to the negative terminal of the dead battery as this could cause a spark that ignites the gasoline in the engine bay.
After the cables have been connected, you need to begin the car and let it run about five minutes. Then, disconnect the cables in reverse. The battery in your saab car keys 9-3 is recharged as you drive. It may take a while it to recharge again. It's a good idea to purchase a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince it that the lost saab key keys aren't attempting to steal the car.
Replacement Case

In the event of theft or any other catastrophe it is recommended to have an extra key. Even even if the key is "new" it will not function.
The dealer will charge the highest dollar for only one working key. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept the new key, without replacing the whole system. That can save you a lot of money. It's also less expensive than waiting until you lose your one key.
