Saab Key Programming
Saab cars that were built prior to 1994 have an immobilizer feature based on coded keys. A new transponder is required for addition of a second key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The issue is that this could be extremely expensive. This is the reason why you should always keep a spare key in your possession.
Transponder key
The transponder keys are keys with an electronic chip that sends a signal to car when it is placed in the ignition. The car then examines the signal to see whether it matches the one that is in the key. If the signals are the same the car will be able to unlock itself and begin. This is a fantastic way to protect your car from theft.
Transponder keys can be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. www.thekeylab.co.uk of the traditional key is easily copied and cut, but the transponder is protected by an electronic chip that guards it. The chip contains a unique code that's programmed into a car's computer order to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. The car can only recognize the key fob when it has an unmodified chip and has been programmed to match. The car will not start if the key is not programmed to match.
It's crucial to ensure that you have an extra key for your Saab. This is particularly important for those who live in a rural area with numerous car thieves. The good part is that you can find a new key for your Saab without having to go to a dealership and pay the expensive prices they ask. You can get an original key made on the spot for less than half of the price you'd spend at the dealership.
Wired key
Saab cars are usually delivered with two keys. If you have only one, it is best to acquire an additional key fob as soon as possible, because if you lose it the car will require an entirely new CIM unit, and the locking cylinders need to be replaced. This can be expensive especially for used vehicles.
The next step is to wire the wires of the column and row to the microcontroller. This is the most laborious part of the project and it will require lots of soldering. There is no standard method to accomplish this, but it's important to plan out 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.
After the columns and rows are soldered, it's time to connect them to key switches. To do this you must place an inverter over each pin of the key switch and then solder it. This will shield the pins from current, thus preventing them from being shortened. A diode allows current to only flow in one direction. It is equipped with a visible indicator of a black line that shows the direction in which the current will flow.
Sanabria states that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508, can help customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and guide the customer through the process, making it easier than replacing the computer inside the vehicle.
Jump starting the battery
The majority of people have a set of jumper cables in their trunk in case of emergency however, jumping a battery on modern vehicles might not be the best option. These vehicles have many digital and computer systems that communicate with one another. A surge in voltage when the battery is connected another one could cause damage to the parts, rendering your car undriveable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of your disabled car. The engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline in the engine compartment.
After the cables have been connected, you need to begin the car and let it run about five minutes. Then disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to fall back. It is a good idea to 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 your lost keys are not trying to steal the car.
Replacement case
Saab owners usually only have one car key, and if that is lost, they'll be charged. The reason is that it's not inexpensive to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other disaster it is best to have a spare key. Even when the key is "new" it will not function.
The majority of locksmiths won't be able to help in the event that you only have one working key and the dealer will charge for the cost of replacing the computer in your vehicle for a replacement. We can reset and reprogram the EEEPROM of your computer to be able to accept a replacement key without replacing the entire system. That can help you save money. It's also a lot cheaper than waiting until you lose the only key.
