Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer system that is based on a set of keys. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that it can be very expensive. Always keep a spare set of keys at hand.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal to car when it is inserted into ignition. The car then analyzes the signal to determine whether it is identical to the one in the key. If the signals match it will open itself and start. This is a great method to deter auto theft and keep your car secure from thieves.

Transponder keys may be an extremely popular accessory for cars, but they are not as secure as traditional keys made of metal. The metal component of a traditional key can easily be cut or copied, while a transponder has an electronic chip that guards it. The chip is a unique code that's programmed into the car's computer in order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. The car will only recognize the key fob if it is equipped with an unmodified chip and programmed to match. If not, the car will reject the key and not start.

It is vital to have an extra saab key programmer key. This is particularly true when you live in a rural area that is home to numerous car thieves. The good news is that it's possible to find a replacement key to your saab ignition key without having to go to a dealership and pay the hefty prices that they demand. In most instances, you can get a new key made on-the-spot for less than half the price of what you'd pay at dealerships.

Wired key

saab 9-5 key replacement cars are usually delivered with two keys. If you own only one, you need to purchase an extra key as soon as you can. This is because if it's lost, the car will need a new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is to connect the wires of the column and row to the microcontroller. This is the toughest part of the project, and it will require a lot of soldering. It's not a common way to do it, but you need to plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After the columns and rows are joined after which it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being shortened. The diode allows current to only flow in one direction. It is equipped with a visible indicator of a black line that shows which way current will flow.

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

Jump starting the battery

Most people keep a few sets of jumper cables in their trunk for emergency situations however, jumping a battery in newer vehicles may not be the best idea. These vehicles have many computers and digital devices that communicate with one another. A surge in voltage while a battery is hooked up to another can fry these components and render your vehicle unable to drive.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface under the hood of your disabled car. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery, as it could spark 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 allow it to run for around five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge as you drive. It will take some time for it to return to its original state. It's a good idea invest in a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and special programming to convince the system that your lost keys are not trying to steal the car.

Replacement Case

saab key fob repair owners usually only have one car key, and if it is lost, they will be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or other disaster the best solution is to purchase a second key as early as you can. However, don't purchase a secondhand key even when it's "new." Keys that are claimed to be new from a second-hand store will not work and are likely to fail at the critical moment.

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 prepare it to accept an alternative key without replacing the whole system. This can help you save money. It's also a lot cheaper than waiting until you lose your sole key.
