Saab Key Programming Saab cars built since about 1994 have an immobilizer system made up of coded keys. A new transponder is required to allow the addition of a second key, as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool. It can be costly. It is always advisable to keep a spare set of keys available. Transponder key The transponder is a type of key that has an electronic chip. The chip transmits a signal when the key is inserted into the ignition. The car will check to see whether the signal matches with the one on the key. If the signals are in sync, the car will open and start. This is an excellent way to protect your car from theft. Transponder keys are a common feature in automobiles, however you should be aware they aren't as secure as traditional keys made of metal. While the metal portion of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip contains a unique code which is programmed into a car's computers in order to identify it. The car will recognize the Saab keyfob and allow it to be turned on. However, it will only do this if the key fob has an unmodified chip that has been programmed to match. The car won't start in the event that the key has not been programmed to match. It's crucial to ensure that you have a spare key for your Saab. This is especially true especially if you reside in a rural location where there are a lot of car thieves. You can purchase a new key for your Saab by going to the dealership without paying their expensive cost. In most instances, you can get a brand new key made right on the spot at a fraction of the cost of what you'd pay at the dealer. Key for Wired Saab cars are usually delivered with two keys. If you own only one, you need to purchase an additional key as quickly as you can. This is because if the key is lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles. The next step is to connect the column and row wires to the microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. There isn't a standard way to accomplish this, but it is essential to determine the way you'll 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. Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the key switch pins from current and prevent them from being shorted. A diode only allows current to flow in one direction, and it comes with a a black band visual indicator that shows the direction in which current will flow. saab replacement key programming 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 customers in some cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and guide the user through the process, making it more simple than replacing the computer inside the vehicle. Jump-starting the battery A lot of people keep a set of jumper cables in their trunk in case of emergency however, jumping a battery for newer cars might not be the best idea. These vehicles have many computers and digital devices that communicate with one another. A voltage spike when the battery is connected to another can fry the components and render your vehicle undriveable. Connect the cables to the vehicle working. Let it 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 of the black cable to an unpainted, clean metal surface underneath the disabled vehicle's hood. An engine block is an ideal choice. Don't connect the black cable to the negative terminal on the dead battery as this could cause an ignition that ignites the gasoline in the engine bay. After the cables have been connected, you should begin the car and let it run about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to return to its original state. It is 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 new computer module and a special program to convince it that your lost keys are not trying to steal the car. Replacement case Saab owners often only have one car key, and if that is lost, they'll be charged. The reason is that it's not cheap to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or any other catastrophe it is recommended to have an extra key. Even when the key is new it won't work. The majority of locksmiths won't be able to help when you only have one working key and the dealer will charge you for the cost of replacing the computer in your vehicle for a replacement. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a replacement key without the need to replace the entire system. This can help you save a significant amount of money. It's also less expensive than waiting until you lose your sole key.
