Saab cars built since about 1994 have an immobilizer system that is based on codes for keys. A new transponder is required for the addition of a second key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
It can be costly. This is why it is important to always have a spare key at 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 placed in the ignition. The car will then check the signal to see if it matches that of the key. If the signals match, the car will unlock and begin. This is a fantastic way to protect 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 can be easily cut or copied, while transponders are protected by an electronic chip that protects it. The chip has a unique code that is encoded into the car's system 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 has been programmed to match. The car won't start if the key is not programmed to match.
It's essential to ensure that you have a spare key for your Saab. This is particularly important when you live in a rural area, where there are many car thieves. You can get a new key for your Saab by visiting the dealership and not paying their expensive cost. You can have a replacement key made on the spot at a fraction of the cost you would pay at dealerships.
Key for Wired
Saab cars are usually supplied with two keys. If you only own one, you should purchase an additional key as fast as you can. This is because if the key is lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly particularly if you are purchasing a used vehicle.
The next step is to connect the row and columns wires to your microcontroller. This is the most tedious part of the project, and it will require lots of soldering. There's no standard way to go about it, but you should determine how to open a saab 93 without a key to get a saab replacement key - click this, to route and solder each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are joined, it is time to connect the key switches. To do this, place a diode across each pin on the key switch and then solder it. This will shield the key switch pins from current and keep them from being shorted. A diode can only allow the current to flow in a single direction, and it has an indicator of black color that indicates the direction in which current will flow.
Sanabria states that some of the tools offered in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.
Jump-starting the battery
Most people keep an assortment of tools in their trunks to start a vehicle in the event of an emergency, however it might not be a good option for vehicles with newer technology. These vehicles are equipped with many digital and computers that communicate with each other. A voltage surge while the battery is connected to another battery could fry these components, rendering your car unable to drive.
Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block is an excellent choice. Do not connect the black cable to the negative terminal of the dead battery because this could cause an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, start the car and let it run for approximately five minutes. Then disconnect the cables in reverse. Keep in mind that the battery on the Saab 9-3 gets recharged when you drive, so it will take a while for the battery to go back down again. It's a good idea purchase a spare fob as soon as you can, since replacing the only working one requires the installation of a new computer module and special programming to convince the system that your lost keys aren't in the process of trying to steal the car.
Replacement Case
Saab owners usually have only one car key, and if it is lost, they'll be charged. It's expensive to add the key and also requires replacing the CIM or TWICE for older models. In the event of theft, or other catastrophe it is recommended to have an extra key. Even even if the key is "new", it will not work.
The dealer will charge you top dollar if you only have one working key. We can, however, reset and re-program your computer's EEPROM to accept the new key without having to replace the entire system. This could save you a great deal of money. It's also a lot cheaper than waiting until you lose your only key.
