saab key fob repair Key Programming
saab 93 key fob replacement cars produced since 1994 use an immobilizer system that relies on coded keys. A new transponder is required to allow the addition of an extra key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
The problem is that this can be extremely expensive. You should always keep a spare set of keys on hand.
Transponder key
The transponder key is a piece of hardware with an electronic chip that sends a signal to the car when it is inserted into the ignition. The car then analyzes the signal to see whether it is the same as the one on the key. If the signals are in sync it will unlock and begin. This is an excellent way to protect your vehicle from theft.
Transponder keys are a common feature in cars, but it is important to know that they're not as secure as classic keys made of metal. While the metal component of a traditional key can be cut and copied the transponder is protected by an electronic chip. This chip contains an unique code that is programmed into a car's computers in order to identify it.
The car will recognize the Saab ignition Key keyfob and permit it to be turned on. The car can only recognize the key fob if it has a chip that is unmodified and has been programmed to match. The car won't start in the event that the key has not been programmed to match.

The next step is to wire the column and row wires to the microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. There isn't a standard method to go about it, but you should plan how to route and connect each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 column.
After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being cut off. A diode lets current only flow in one direction. It features a visual indicator of a black line that shows which way current will flow.
Sanabria states that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 will assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and guide the user through the procedure, making it simpler than replacing the computer inside the vehicle.
Jumpstarting the battery
Most people keep a few sets of jumper cables in their trunks to use in an emergency however, jumping a battery in newer vehicles might not be the best idea. These vehicles are equipped with many digital and computers that communicate with each other. A voltage spike when the battery is connected to another can fry the components and render your car unable to drive.
Connect the cables to the vehicle working. Allow it to run for two minutes. 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 clean unpainted metal surface beneath 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, since it could ignite a spark that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that is disabled and let it run for approximately five minutes before you disconnect them in reverse order. Be aware that the battery in your Saab 9-3 is charged when you drive, so it may take some time for the battery to go back down again.

In the event of theft, or any other disaster it is recommended to have an extra key. Even it's "new" it will not work.
The dealer will charge you the most expensive dollar for only one working key. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. That can save you a lot of money. It's much cheaper than wait until you lose the only key.
