Saab cars built from 1994 have an immobilizer system that is based on a set of keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
The issue is that this could be very expensive. This is why you should always have a spare key on hand.
Transponder key
The transponder key comes equipped with an electronic chip. It transmits a signal to the car when it is inserted into ignition.

This is a great method to deter car theft and keep your car safe from thieves.
Transponder keys can be a popular addition to cars, but they are not as safe as traditional metal keys. The metal portion of a traditional key is easily copied and cut, but transponders are protected by an electronic chip that protects it. This chip contains a unique code embedded into the car's computer to identify it.
The car will recognize the Saab keyfob, and allow it to turn 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 will not start in the event that the key has not been programmed to match.

For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the rows and column are joined after which it is time to connect the key switches. To do this, you need to place a diode across each key switch pin and then solder it. This will shield the pins from current, preventing them from being cut off. A diode can only allow the flow of current to be in one direction, and it has the black band as a visual indicator that shows the direction in which current will flow.
Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY users in some cases replace keys in the program and restore lost immobilizer data, Sanabria says.

Jump-starting the battery
Most people keep the set in their trunks to jump-start a car in an emergency, but it might not be the best option for vehicles with newer technology. These cars have a variety of digital and electronic devices that communicate with one another.

The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline inside the engine compartment.
Once the cables are connected, start the car and let it run for approximately five minutes. Then, disconnect the cables in reverse.

Keys that are claimed as new from a second-hand store will not work and are almost guaranteed to fail at the crucial moment.
The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order for it to accept a replacement key without having to replace the entire system. That can save you a lot of money. It's less expensive than waiting until you lose the sole key.
