Saab Key Programming

saab 9-3 key cars made since 1994 come with an immobilizer system based on coded keys. A new transponder is required for the addition of an additional key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The problem is that it can be quite costly. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder is a type of key with an electronic chip. This chip sends out a signal when the key is inserted into the ignition. The car then examines the signal to see whether it matches the one on the key. If the signals are in sync then the car will be able to unlock and start. This is an excellent way to guard your car against theft.

Transponder keys are a popular feature in automobiles, however it is important to know that they're not as secure as traditional metal keys. The metal component of the traditional key can easily be cut and copied, whereas transponders have an electronic chip which protects it. This chip contains an unique code that is programmed into a car's computer order to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car will only recognize the key fob when it has a chip that is unmodified and has been programmed to match. In the absence of that, the car will reject the key and not start.

It is vital to have a spare Saab key. This is especially important if you live in a rural region where there are a lot of car thieves. The good thing is that you can get a replacement key for your Saab without needing to visit an auto dealership and pay the hefty prices that they charge. You can get the replacement key on the spot at a fraction of the price you'd pay at a dealership.

Wired key

Saab cars usually come with two keys when they're new. If you have only one, it's best to acquire an extra key fob as soon as possible in case you lose it the car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be costly especially if purchasing a used car.

The next step is to connect the wires for the column and row to the microcontroller. This is the toughest part of the project, and it will require a lot of soldering. There is no standardized way to accomplish this, but it is essential to determine how you will route and solder the columns and rows. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 column.

After the rows and column are joined after which it is time to connect the key switches. To do this, place a diode across each key switch pin and solder it. This will shield the pins of the key switch from current and prevent them from being shorted. A diode permits current to only flow in one direction. It is equipped with a visible indicator of a black line that indicates which direction current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 can assist shoppers or DIY customers to program replacement keys and restore the immobilizer's data. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunk in case of emergency, but jumping a battery in newer automobiles might not be the best choice. These vehicles are equipped with digital and computers that communicate with each other. A voltage spike when the battery is connected another battery could damage the components, rendering your car undriveable.

Start the working vehicle and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of your disabled car. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal of the dead battery as this could cause an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you should start the Duplicate Car keys Cost and let it run for approximately five minutes. Then, disconnect them in reverse. Keep in mind that the battery on your saab ignition key 9-3 is recharged when you drive, so it could take a while to get the battery down. You should purchase a second key fob, as soon as you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Saab owners usually only have one car key, and if that is lost saab key, they will be charged. It's costly to add a key and requires replacing the CIM or TWICE in the case of older models. It is best to have a backup key in case of theft or any other catastrophe the best solution is to buy an extra key as quickly as you can. Even it's "new", it will not function.

The dealer will charge you the most expensive dollar for only one working key. However, we can reset and reprogram the computer's EEPROM to accept the new key, without replacing the whole system. That can save you lots of money. It's much cheaper than waiting until you loose the only key.
