saab ignition Key replacement Key Programming
Saab cars manufactured since 1994 feature an immobilizer system that is based on key codes. A new transponder is required in order to enable the addition of an additional key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The issue is that this can be extremely expensive. Always keep an extra set of keys at hand.
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 checks to see whether the signal matches the one on the key. If the signals match the car will be able to unlock itself and begin. This is a fantastic way to safeguard your car from theft.
Transponder keys are an extremely popular accessory for cars, but they're not as secure as traditional metal keys. The metal part of the traditional key can be easily cut and copied, whereas transponders are protected by an electronic chip that protects it. The chip is equipped with a unique code programmed into the car's computers to identify it.
The car will recognize the Saab keyfob and allow it to turn on. The car will only recognize the key fob if the device has an unmodified chip and has been programmed to match. The car won't start if the key is not programmed to match.
It is essential to ensure that you have an extra key for your saab 9 3 key replacement. This is particularly important especially if you reside in a rural area where there are a lot of car burglars. The good news is that you can obtain a replacement key for your saab 93 key without needing to visit an auto dealer and pay the hefty prices that they ask. You can have a replacement key created on the spot for less than half the cost you would spend at a dealership.
Key for Wired
Saab cars are usually delivered with two keys. If you only have one, it's an ideal idea to purchase an additional key fob as soon as is possible, because if you lose it, the car will require a new CIM unit and the locking cylinders need to be replaced. This can be costly especially if you're purchasing a used car.
The next step is to wire the column and row wires to the microcontroller. This is the toughest part of the project, and 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 rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered together then it's time to connect the key switches. To do this, put a diode across each pin of the key switch and solder it. This will protect the pins on the key switch 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 indicates the direction in which current will flow.
Sanabria states that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508, can help customers who are shopping or DIY customers to program replacement saab 9-3 key keys and restore data from the immobilizer. The tools connect to OBD ports and guide the user through each step and make the process more straightforward than replacing the vehicle's computer.
Jumpstarting the battery
The majority of people have a set of jumper cables in their trunk to use in an emergency however, jumping a battery on newer automobiles might not be the best idea. These cars are equipped with a variety of digital and computers that communicate with each other. A voltage spike when batteries are connected to another battery could damage the components making your car inoperable.
Start the vehicle you are using and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. 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 under the disabled vehicle's hood. An engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite the gasoline inside the engine compartment.
Once the cables are connected, begin the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. Remember that the battery on your Saab 9-3 is charged during your drive, which means it will take a while to get the battery back to normal. You should purchase an additional key fob as soon as you can. Replacing the one that works requires the installation and programming of a new computer chip.
Replacement Case
Many Saab owners have only one key for their car and if they lose it, it's going to cost them. It's costly to add a key and requires replacing the CIM or TWICE in the case of older models. In the event of theft, or other catastrophe, it is best to have a spare key. Even when the key is "new", it will not work.
The dealer will charge the highest dollar if you have only one working key. We can, however, reset and re-program the computer's EEPROM to accept the new key without having to replace the whole system. This can save you a lot of money. It's more affordable than waiting until you lose your only key.
