The Leading Reasons Why People Perform Well On The Saab Ignition Key Replacement Industry
Saab Key Programming
Saab cars built since about 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required for addition of a second key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
It can be costly. how to program saab 9-3 key fob should always keep a spare set of keys available.
Transponder key
The transponder key is a piece of hardware 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 with the one on the key. If the signals are in sync the car will then open and start. This is a great method to prevent car theft and keep your vehicle secure from thieves.
Transponder keys may be a popular addition to automobiles, but they are not as secure as traditional metal keys. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. The chip is equipped with an unique code that is embedded into the car's computer to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if your key fob is unmodified and has a chip that has been programmed to match it. If not, the car will reject the key and won't start.
It is vital to have an extra Saab key. This is especially true when you live in a rural area with many car thieves. The good news is that it's possible to obtain a replacement key for your Saab without needing to visit a dealer and pay the high costs that they demand. You can have a replacement key made on the spot for less than half the cost you would spend at the dealership.
Key for Wired
Saab cars are usually provided with two keys. If you only have one, you should get an additional key as soon as you can. This is because if the key is lost the car will require a new CIM and the locking cylinders replaced. This could be expensive especially if you're buying a used car.
The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project and will require a good amount of soldering. There is no standard method to accomplish this, but it is crucial to plan the way you'll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from being cut off. A diode only allows current to flow in one direction, and it comes with a the black band as a visual indicator that shows the direction in which current will flow.
Sanabria says that some of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 are able to assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.
Jumpstarting the battery
A majority of people keep a set in their trunks to jump start a vehicle in the event of an emergency, but it might not be the best idea for cars with more modern technology. These vehicles have many digital and electronic devices that communicate with one another. A surge in voltage when a battery is connected to another could cause damage to the components making your car unusable.
Start the vehicle you are using and let it run for about two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the damaged car. The engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline in the engine compartment.
Once the cables are connected, begin the car and let it run about five minutes. Then disconnect the cables in reverse. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to fall back. It's a good idea purchase a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and a special program to convince the system that your lost keys aren't attempting to steal the car.
Replacement case
Many Saab owners have only one key for their car and if they lose it, key, it will cost them. The reason is that it's not inexpensive to add a new key, and it requires 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. But don't buy a used key, even if it's "new." Keys that are claimed to be new from a second-hand store will not be effective and are almost guaranteed to fail in the crucial moment.
Most locksmiths aren't able to help if you have only one working key and the dealer will charge you top dollar to replace the computer in your car to create a replacement. We can reset and reprogram the EEEPROM of your computer for it to accept a new key without replacing the entire system. This could save you a significant amount of money. It's also less expensive than waiting until you lose your only key.
