Saab Key Programming
Saab cars that were built prior to 1994 have an immobilizer feature built on coded keys. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The problem is that this can be very expensive. Always keep an extra set of keys at 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 ignition. The car will then check the signal to see whether it is identical to the one that is in the key. If the signals are the same, the car will unlock itself and begin. This is a great way to safeguard your car from theft.
Transponder keys are a favored feature in vehicles, but you should be aware they're not as secure as classic metal keys. The metal portion of a traditional key can be easily cut or copied, while a transponder has an electronic chip which protects it. This chip contains an unique code that is programmed into a car's computer order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if the device has an unmodified chip and has been programmed to match. Otherwise, the car will reject the key and refuse to start.

There's no standard way to do this, but it is crucial to plan the routes you'll use to solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.
After the rows and column are soldered together, it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and stop them from being shorted. The diode allows current to only flow in one direction. It features a visual indicator, a black band, that shows which way current will flow.
Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY users in some cases replace keys in the program and restore lost immobilizer information, Sanabria says.

Jumpstarting the battery
A lot of people keep an item in their trunk to jump-start a car in case of emergency, but it may not be a good option for vehicles with newer technology.

The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline that is in the engine compartment.
