Indisputable Proof That You Need Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since 1994 feature an immobilizer system that is based on keys that are coded. A new transponder is required in order to enable the addition of an extra key, and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.
This can be expensive. Always keep an extra set of keys at hand.
Transponder key
The transponder key comes equipped with an electronic chip. It sends a signal to car when it is put into the ignition. The car then checks to see if the signal matches the one on the key. If the signals are identical the car will then unlock itself and start. This is an excellent way to safeguard your car from theft.
Transponder keys are a popular feature in vehicles, but you should be aware that they are not as secure as classic metal keys. The metal part of the traditional key is easily cut and copied, whereas the transponder is protected by an electronic chip that protects it. The chip has a unique code that's programmed into a car's computer order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it will only do this if the key fob has an unmodified chip that has been programmed to match it. The car will not start in the event that the key has not been programmed to match.
It is essential to ensure that you have a spare key for your Saab. This is especially true for those who live in a rural region where there are a lot of car thieves. You can purchase a new key for your Saab by going to the dealership, without having to pay their high cost.

Wired key
Saab cars are usually supplied with two keys. If you have only one, it is recommended to get an extra key as soon as you can. This is because if you lose it and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly particularly for used cars.
The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There's no standard way to go about it, but you should think about how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.
Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins on the key switch from current and prevent them from being shorted. A diode lets current only flow in one direction. It features a visual indicator with a black band that indicates the direction in which current will flow.
Sanabria says that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 can assist customers shopping or DIY customers to program replacement keys and restore immobilizer data. 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.
Jump-starting the battery
Most people keep a set in their trunk to jump-start their vehicle in an emergency, but it might not be the best idea for newer cars. These vehicles are equipped with many digital and computer systems that communicate with each other. A voltage surge when the battery is connected another battery could damage the components and render your vehicle unusable.
Start the working vehicle and let it run for about two minutes before you connect the cables to the one that is disabled. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be an ideal choice. Do not 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.
After the cables have been connected, begin the car and let it run about five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged while you drive. It takes a while for it to fall back. It's a good idea purchase a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and special programming to convince it that your lost keys aren't trying to steal the car.
Replacement case
Many Saab owners have only one key for their vehicle and if they lose it, they'll be charged. The reason for this is that it's costly 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 any other calamity, it is best to have an extra key. saab fob key replacement buy a secondhand key, even it's "new." Keys that are claimed as new from sellers selling aftermarket keys won't work and are almost guaranteed to fail in the crucial moment.
The dealer will charge you top dollars if you only have one working key. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept a new 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 one key.
