Undeniable Proof That You Need Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 feature an immobilizer that relies on key codes. To add an additional key, you need a new transponder, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The issue is that it can be very expensive. This is why you should always have a spare key on hand.
Transponder key
The transponder keys are keys with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car then analyzes the signal to determine whether it matches the one that is in the key. If the signals are in sync the car will then unlock and begin. This is a great way to protect your vehicle from theft.
Transponder keys are a common feature in vehicles, but you should be aware that they are not as secure as traditional metal keys. While the metal part of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip has 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 turn on. The car can only recognize the key fob if the device has an unmodified chip and has been programmed to match. Otherwise, the car will reject the key and refuse to start.
It is important to have an extra Saab key. This is especially true if you live in a rural area, where there are many car thieves. The good news is that it's possible to get a replacement key for your Saab without having to go to a dealer and pay the hefty prices that they ask. In the majority of instances, you can get a brand new key made right on the spot for less than half the cost you'd pay at dealerships.
Key for Wired
Saab cars are typically delivered with two keys. If you have only one, it is a good idea to get an additional key fob as soon as is possible, because if you lose it the car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This could be expensive, especially if you are buying a second-hand car.
The next step is to connect the wires of columns and row to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There is no standard method to accomplish this, but it is crucial to plan the routes you'll use to solder the columns and rows. For this keyboard, there are five rows and 17 columns, which means 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. To do this, you need to place a diode over each key switch pin and solder it. This will protect the pins that are used for key switches from current and also prevent them from being shorted. The diode will only allow the flow of current to be in one direction, and has a an indicator of black color that shows the direction in which current will flow.
Sanabria says that some of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep an item in their trunk to jump-start their vehicle in the event of an emergency, but it might not be the best idea for vehicles that are newer. These cars are equipped with a variety of computers and digital devices which communicate with one another. A surge in voltage while the battery is connected to another one could damage these components and render 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 non-working one. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface under the hood of the damaged vehicle. The engine block is a great option. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite the gasoline in the engine compartment.
Once the cables are connected, turn on the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. Be aware that the battery of your Saab 9-3 is recharged when you drive, and it can take a while for the battery to go back to its original level. It's a good idea to invest in a spare key fob as soon as you can, since replacing the sole working one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't in the process of trying to steal the car.
Replacement Case
Many Saab owners have only one key for their vehicle and if they lose it, it's going to cost them. The reason is that it's not cheap to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In replacement saab key g28carkeys.co.uk of theft, or any other calamity it is recommended to have an extra key. Even when the key is "new" it will not function.
Most locksmiths aren't able to help if you have only one working key and the dealer will charge high fees to replace the computer in your car to create a replacement. We can, however, reset and reprogram the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This can save you a lot of money. It's less expensive rather than wait until you loose the only key.
