Saab Key Programming
Saab cars manufactured since 1994 utilize an immobilizer system based on a set of keys. A new transponder is required for addition of a second key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The problem is that this can be quite costly. This is why you should always have a spare key available.
Transponder key
The transponder is a key equipped with an electronic chip. This chip sends out a signal when the key is inserted in the ignition. The car checks to see whether the signal matches the one on the key. If both signals match the car will then unlock itself and start. This is an excellent way to guard your car against theft.
Transponder keys are an increasingly popular feature in automobiles, but you should be aware that they are not as secure as classic metal keys. The metal component of the traditional keys can be easily copied and cut, but the transponder is protected by an electronic chip that guards it. The chip has a unique code that is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it can 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 refuse to start.
It is essential to ensure that you have a spare key for your Saab. This is especially important for those who live in a rural location where there are many car thieves. The good news is that it's possible to get a replacement key for your Saab without having to go to an auto dealership and pay the expensive prices they ask.

Key for Wired
saab key fob replacement cars typically come with two keys when new. If you have only one, it is a good idea to get an extra key fob as soon as you can in case you lose it, your car will require an entirely new CIM unit, and the locking cylinders will need to be replaced. This can be costly especially for used vehicles.
The next step is to wire the wires of the column and row to the microcontroller. This is the toughest component of the project and it will require a lot of soldering. There isn't a standard way to accomplish this, but it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.
Once the rows and columns 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 and prevent them from being shorted. A diode permits current to only flow in only one direction. It has a visual indicator with a black band that shows which way current will flow.
A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY customers in certain instances replace keys in the program and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the user through the process, making it easier than replacing the computer in the vehicle.
Jumpstarting the battery
Most people keep a few sets of jumper cables in their trunk for emergency situations however, jumping a battery for newer vehicles might not be the best idea. These cars have a variety of electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another battery could fry these components and render your car unable to drive.
Start the working vehicle and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the damaged car. The engine block is a great option. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite gasoline in the engine compartment.
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 is recharged while you drive. It will take a while for it to recharge again. It's a good idea to invest in a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that the lost keys are not trying to steal the car.
Replacement case
saab ignition key [Highly recommended Online site] owners often only have one car key, and if it is lost, they'll be charged. The reason is that it's not inexpensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or other catastrophe it is best to have a spare key. Even even if the key is "new", it won't work.
The dealer will charge the highest dollar if you only have one working key. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This can help you save money. It's also cheaper than waiting until you lose the only key.
