15 Reasons You Shouldn't Be Ignoring Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since about 1994 feature an immobilizer mechanism made up of coded keys. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
It can be costly. This is the reason why you should always have a spare key at hand.
Transponder key
The transponder is a type of key equipped with an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals are in sync it will open and start. This is a great method to protect your vehicle from theft.
Transponder keys can be an extremely popular accessory for automobiles, but they are not as secure as traditional keys made of metal. The metal part of the traditional key is easily cut and copied, however transponders have an electronic chip which protects it. The chip has a unique code that is encoded into the car's system to identify it.
The car will recognize the Saab keyfob and allow it to turn on. However, it can only do this if the fob has a non-modified chip that has been programmed to match. In the absence of that, the car will reject the key and refuse to start.
It is crucial to have a spare Saab key. This is especially important if you reside in a rural area that is home to numerous car thieves. The good news is that it's possible to find a replacement key to your Saab without needing to visit an auto dealership and pay the high costs that they ask. You can have the replacement key on the spot at a fraction of the cost you would pay at the dealership.
Key for Wired
Saab cars typically come with two keys upon purchase. If you have only one, you should get an additional key as soon as you can. This is because if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.
The next step is to connect the wires for columns and row to your microcontroller. This is the most tedious part of the project, and it will require a lot of soldering. There is no standard method to accomplish this, but it is crucial to plan the routes you'll use to solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 5 rows and 17 column.
After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and keep them from being shorted. A diode permits current to only flow in one direction. It is equipped with a visible indicator with a black band that indicates which direction current will flow.
Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY customers in certain cases replace keys in the program and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the user through each step which makes the process much easier than replacing the vehicle's computer.
Jumpstarting the battery
Most people keep a set of jumper cables in their trunk for emergency situations, but jumping a battery on newer vehicles may not be the best idea. These vehicles are equipped with digital and computers that communicate with each other. A surge in voltage while a battery is hooked up to another one could damage these components and render your vehicle unable to drive.
Start the working vehicle and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of the damaged car. The engine block is a great choice. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which could ignite the gasoline in the engine compartment.
After the cables have been connected, you should start the car and let it run about five minutes. Then disconnect the cables in reverse. Be aware that the battery in the Saab 9-3 will be charged during your drive, which means it can take a while for the battery to go back to normal. It is recommended to purchase another key fob as soon as you can. Replacing the one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Saab owners usually have only one car key, and if it is lost, they'll be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. 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.
saab keys to help with a single working key and the dealer will charge you for the cost of replacing the computer in your vehicle for a replacement. However, we can reset and re-program your computer's EEPROM to accept a new key without replacing the entire system. This could save you a lot of money. It's less expensive than waiting until you lose the only key.
