saab Ignition Key Replacement Key Programming

saab 900 key cars made since 1994 have an immobilizer feature built on coded keys. The addition of a key requires a new transponder and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The problem is that this can be quite costly. Always keep an extra set of keys 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 see whether it matches the one in the key. If the signals match the car will then unlock itself and begin. This is a great method to protect your vehicle from theft.

Transponder keys are an extremely popular accessory for automobiles, but they are not as safe 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 has a unique code which is programmed into a car's computer in order to identify it.

The car will recognize the saab 9-3 key fob programming keyfob and allow it to turn on. However, it can only do this if your key fob has an unmodified chip that has been programmed to match. Otherwise, the car will refuse to accept the key and will not start.

It is essential to have an extra Saab key. This is especially true for those who live in a rural area that is home to many car thieves. The good news is that it's possible to obtain a replacement key for your Saab without needing to visit an auto dealer and pay the high prices that they ask. In most cases, you can have a new key created on-the-spot at a fraction of the cost of what you would pay at an auto dealer.

Key for Wired

Saab cars usually come with two keys upon purchase. If you have only one, it is a good idea to get an extra key fob as quickly as you can in case you lose it the car will require an entirely new CIM unit and the locking cylinders will have to be replaced. This can be expensive especially for cars that are used.

The next step is to wire the row and column wires to the microcontroller. This is the most laborious component of the project and will require lots of soldering. It's not a standard way to do it, however, you should think about how to connect and solder each column and row. 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 joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins on the key switch from current and also prevent them from being shorted. The diode allows current to only flow in one direction. It features a visual indicator that is black, that shows the direction in which the current will flow.

Sanabria says that a few of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508, can help customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep an item in their trunk to jump-start a vehicle in the event of an emergency, but this might not be the best idea for vehicles that are newer. These vehicles are equipped with digital and computer systems that communicate with each other. A surge of voltage when a battery is connected to another could cause damage to the components and render your vehicle unusable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood--the engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery as it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle you are not using and let it run for about five minutes before disconnecting them in reverse order. Remember that the battery on your Saab 9-3 is recharged while you drive, so it could take a while for the battery to go down. It's a good idea to purchase a spare fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't trying to steal the car.

Replacement Case

Saab owners often only have one car key, and if it is lost, they will be charged. It's expensive to add a key and requires replacing the CIM or TWICE in the case of older models. It's recommended to have a backup key in the event of theft or other disaster the best solution is to purchase a second key as quickly as you can. Don't buy a secondhand key, even when it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't perform and are almost certain to fail in the most critical moment.

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