Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer system that relies on a set of keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key available.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal back to the car when it is inserted into the ignition. The car then checks the signal to determine if it matches that of 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 an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. The metal part of the traditional key is easily cut or copied, while the transponder is protected by an electronic chip that guards it. The chip has a unique code that is inserted into the car's computer in order to identify it.

When a saab ignition key replacement key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match. The car will not start if the key is not programmed to match.

It is vital to have a spare Saab key. This is especially true if you reside in a rural location that has many car thieves. The good news is that it's possible to obtain a replacement key for your Saab without having to go to a dealership and pay the high prices that they charge. You can get an original key made on the spot at a fraction of the price you'd spend at dealerships.

Wired key

Saab cars usually come with two keys upon purchase. If you own only one, you should get an additional key as fast as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly especially if you're buying a second-hand car.

The next step is to connect the wires for the column and row to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard way to accomplish this, but it is crucial to plan the routes you'll use to solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place an inverter over each key switch pin and then solder it. This will protect the key switch pins from current and prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it comes with a the black band as a visual indicator that indicates the direction in which current will flow.

Sanabria states that some of the tools sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508, can help customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the car's computer.

Jump starting the battery

A majority of people keep an assortment of tools in their trunks to jump-start their vehicle in the event of an emergency, but it might not be the best idea for newer cars. These vehicles are equipped with a number of digital and electronic devices that communicate with one another. A surge in voltage while the battery is connected to another one could damage these components and render your car undriveable.

Start the vehicle that is working and allow it to run for around 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 clear, unpainted metal surface beneath the hood of the affected vehicle. The engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery, since it could spark an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you should begin the car and let it run for approximately five minutes. Then, disconnect them in reverse. Be aware that the battery of the saab key code 9-3 will be charged during your drive, which means it will take a while for the battery to come back to normal. You should purchase a second key fob, as soon as possible. Replacing the one that works requires the installation and programming of a new computer chip.

saab 93 key replacement owners usually only have one car key, and if it is lost, they will be charged. It's costly to add a key and requires replacing the CIM or TWICE in the case of older models. In the event of theft or other catastrophe, it is best to have a spare key. Even it's "new" it will not function.

The dealer will charge the highest dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM for it to accept a replacement key without the need to replace the entire system. This can help you save a significant amount of money. It's less expensive than waiting until you lose your only key.
