saab ignition key Key Programming

Saab cars made from 1994 have an immobilizer system based on key codes. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

This can be expensive. It is recommended to always have a spare set of keys available.

Transponder key

The transponder key is a key with an electronic chip that transmits a signal to the car when it is placed in the ignition. The car will check to see whether the signal matches with the one on the key. If the signals are in sync it will unlock and start. This is a great method to protect your car from theft.

Transponder keys could be an extremely popular accessory for cars, but they're not as safe as traditional keys made of metal. The metal portion of a traditional keys can be easily cut and copied, whereas the transponder is protected by an electronic chip which protects it. The chip has a unique code that's programmed into a car's computer in order to identify it.

When a saab replacement key programming key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob has a non-modified chip that has been programmed to match the original. Otherwise, the car will refuse to accept the key and will not start.

It is crucial to have an extra Saab key. This is particularly true if you reside in a rural location that has many car thieves. The good news is that you can obtain a replacement key for your Saab without needing to visit a dealership and pay the hefty prices they ask. In most cases, you can have a new key made on-the-spot at a fraction of the cost of what you'd pay at a dealer.

Key for Wired

Saab cars are typically delivered with two keys. If you only have one, it is best to acquire an extra key fob as soon as is possible since if you lose it the car will require a new CIM unit and the locking cylinders will need to be replaced. This can be expensive especially for used vehicles.

The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. It's not a standard way to do it, but you must consider how you will connect and solder each column and row. For this keyboard, there are five 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 the time to connect them to key switches. To do this, you need to place a diode on each pin of the key switch and solder it. This will shield the pins from current and prevent them from being shorted. The diode will only allow current to flow in one direction, and it comes with a an indicator in black that indicates the direction in which current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508, can help shoppers or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and guide the user through the procedure, making it simpler than replacing the computer inside the vehicle.

Jumpstarting the battery

The majority of people have a set of jumper cables in their trunk in case of emergency however, jumping a battery in newer vehicles may not be the best idea. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A voltage spike when the battery is connected to another can fry these components and render your car unable to drive.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the battery that is not working. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface under the hood of the damaged car. The engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery as it could spark a spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle that has been disabled and let it run for approximately five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge as you drive. It may take a while it to recharge again. You should invest in a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Many saab spare key owners only have one key for their car and if they lose that the cost will be. It's expensive to buy an additional key and it requires replacing the CIM or TWICE for older models. It is best to have a spare key in the event of theft or any other catastrophe, and the best way is to buy an extra key as early as you can. But don't buy a used key even the case that it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't perform and are almost certain to fail in the most critical moment.

The dealer will charge the highest dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer for it to accept a replacement key without having to replace the entire system. This could save you a lot of money. It's also a lot cheaper than waiting until you lose your only key.
