Why We Our Love For Saab Ignition Key Replacement (And You Should Too!)
Saab Key Programming
Saab cars manufactured since 1994 feature an immobilizer mechanism built on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
This can be expensive. This is why it is important to always have a spare key on hand.
Transponder key
The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is put into the ignition. The car then checks to see whether the signal matches the one on the key. If the signals match it will open and start. This is a great way to prevent auto theft and keep your vehicle secure from thieves.
Transponder keys are an extremely popular accessory for automobiles, but they are not as safe as traditional keys made of metal. The metal component of a traditional key is easily cut or copied, while the transponder is protected by an electronic chip that safeguards it. This chip contains 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. But, it's only able to do so if the key fob has a non-modified chip that has been programmed to match it. The car will not start if the key is not programmed to match.
It's essential to ensure that you have a spare key for your Saab. This is particularly important especially if you live in a rural area with many car thieves. The good part is that you can obtain a replacement key for your Saab without needing to visit an auto dealer and pay the high costs that they demand. In most instances, you can get a new key created on-the-spot at a fraction of the price of what you'd pay at dealerships.
Key for Wired
Saab cars are typically delivered with two keys. If you own only one, you should purchase an additional key as fast as you can. This is because if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially for used cars.
The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a great deal of soldering. There isn't replacement saab 9-3 key to accomplish this, however it is important to think about the routes you'll use to 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 joined It is now time to connect the key switches. To do this, you need to place a diode across each pin on the key switch and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. A diode allows current to only flow in one direction. It has a visual indicator of a black line that shows the direction in which the current will flow.
Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 are able to assist customers shopping or DIY users to program replacement keys and restore immobilizer information. The tools connect to the OBD port and automatically guide the user through the process, making it easier than replacing the computer in the vehicle.
Jump-starting the battery
A lot of people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery for newer automobiles might not be the best idea. These cars are equipped with a variety of computers and digital devices which communicate with each other. A surge in voltage when a battery is hooked up to another battery could fry the components and render your car undriveable.
Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite the gasoline inside 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. Remember that the battery on your Saab 9-3 is charged while you drive, so it can take a while to get the battery back down again. You should consider purchasing a second key fob, when you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.
Replacement case
Many Saab owners have only one key for their vehicle and if they lose it, key, it will cost them. It's expensive to purchase a key and requires replacing the CIM or TWICE for older models. It's recommended to have a second key in the event of theft or other disaster, and the best way is to purchase a second key as quickly as you can. Don't purchase a used key even it's "new." Keys that are claimed as new from aftermarket sellers will not be effective and are almost guaranteed to fail in the crucial moment.
The dealer will charge you top dollar for only one working key. We can, however, reset and re-program the computer's EEPROM to prepare it to accept a new key without replacing the whole system. That can help you save money. It's also cheaper than waiting until you lose your only key.
