Saab key battery Replacement Key Programming
Saab cars made from 1994 have an immobilizer system that is based on key codes. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.
The issue is that this can be quite costly. This is the reason why you should always have a spare key on hand.
Transponder key
The transponder key is a piece of hardware with an electronic chip that sends a signal back to the car when it is inserted into ignition. The car then analyzes the signal to see whether it matches that of the key. If the signals match the car will then unlock itself and start. This is a great method to protect your vehicle from theft.
Transponder keys are an increasingly popular feature in automobiles, however you should be aware that they're not as secure as classic metal keys. While the metal parts of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. This chip has an unique code that is embedded into the car's computer to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if it is equipped with a chip that is unmodified and programmed to match. In the absence of that, the car will reject the key and refuse to start.

After the columns and rows are soldered, it's time to connect them to key switches. To do this, put a diode over each pin of the key switch and then solder it. This will protect the pins from current, preventing them from being cut off. The diode allows current to only flow in only one direction. It has a visual indicator with a black band that shows the direction in which the current will flow.
Sanabria says that a few of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 will assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data.

Jump-starting the battery
A lot of people keep a set in their trunks to jump start a vehicle in the event of an emergency, but it may not be the best option for vehicles with newer technology. They have numerous electronic devices and computers that communicate with each other. A voltage spike when the battery is connected to another can fry the components and render your vehicle unable to drive.
Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface underneath the hood of the affected vehicle. The engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery, as this could cause a spark that ignites the gasoline in the engine bay.

Replacement case
Many Saab owners have only one key for their car and if they lose it, they'll be charged. It's costly to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It's recommended to have a spare key in the event of theft or any other catastrophe and the best option is to purchase an additional key as quickly as you can. Don't buy a secondhand key even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the crucial moment.
The dealer will charge you the most expensive dollar if you have only one working key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This could help you save a significant amount of money. It's also less expensive than waiting until you lose your sole key.
