Saab Key Programming
Saab cars produced from 1994 have an immobilizer system 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 it can be very costly. Always keep an extra set of keys on hand.
Transponder key
The transponder is a type of key that is equipped with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then examines the signal to determine whether it is the same as the one in the key. If the signals match it will unlock and start. This is a great way to safeguard your car from theft.
Transponder keys are an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. While the metal parts of a conventional key can be cut and copied the transponder is protected by an electronic chip. The chip contains a unique code that's programmed into a car's computer in order to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the key fob is unmodified and has a chip that has been programmed to match the original. In the absence of that, the car will reject the key and not start.
It's crucial to ensure that you have a spare key for your Saab. This is especially true for those who live in a rural area with many car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying their expensive prices. In most cases, you can have a new key created on-the-spot at a fraction of the cost you'd pay at an auto dealer.
Wired key
Saab cars are typically delivered with two keys. If you have only one, it is a good idea to get an additional key fob as soon as you can since if you lose it, the car will require a new CIM unit, and the locking cylinders will have to be replaced. This can be costly, especially for used cars.
The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There is no standardized way to accomplish this, however it is crucial to plan how you will route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered, it's time to connect them to key switches. To do this, put a diode across each pin of the key switch and then solder it. This will protect the pins from current, thus preventing them from getting shorted. A diode allows the current to flow in a single direction, and it comes with a an indicator of black color that indicates the direction in which current will flow.
Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain instances program replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer inside the vehicle.

Most people keep a few sets of jumper cables in their trunks to use in an emergency however, jumping a battery on newer cars might not be the best idea. These vehicles have many digital and computer systems that communicate with one another. A surge in voltage while a battery is hooked up to another could cause damage to these components and leave your car undriveable.
Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface under the hood of the disabled vehicle. The engine block is an excellent option. 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.
Once the cables are connected, start the car and let it run about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It will take some time for it to recharge again. It's a good idea buy a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't attempting to steal the car.
Replacement case
Many Saab owners only have one key for their car and if they lose that it's going to cost them. The reason for this is that it's costly to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended to have a second key in the event of theft or any other catastrophe the best solution is to purchase a second key as soon as you are able to. Even it's "new" it will not function.
Most locksmiths aren't able to help in the event that you only have one working key and the dealer will charge high fees to replace the computer in your vehicle to make a replacement. We can reset and reprogram the computer's EEEPROM in order for it to accept a new key without the need to replace the entire system. This could help you save money. It's also a lot cheaper than waiting until you lose your only key.
