Saab Key Programming

saab key fob repair cars produced since 1994 utilize an immobilizer that relies on coded keys. To add an additional key, you need a new transponder and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

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

Transponder key

The transponder can be described as a key that is equipped with an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car will check to see whether the signal matches the one on the key. If both signals match, the car will unlock itself and begin. This is an excellent way to safeguard your car from theft.

Transponder keys could be an increasingly popular feature for cars, but they are not as secure as traditional keys made of metal. While the metal portion of a traditional key could be cut and copied the transponder is protected by an electronic chip. This chip has a unique code that is programmed into the car's computers to identify it.

The car will recognize the Saab keyfob and permit it to turn on. The car will only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. The car won't start if the key is not programmed to match.

It is essential to ensure that you have a spare key for your Saab. This is particularly important when you live in a rural location where there are numerous car thieves. The good thing is that you can find a new key for your Saab without having to go to an auto dealership and pay the high prices that they charge. You can have a replacement key made on the spot at a fraction of the price you'd spend at an auto dealer.

Key for Wired

Saab cars typically come with two keys when new. If you have only one, it is a good idea to get an extra key fob as soon as you can since if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders have to be replaced. This could be expensive especially if buying a second-hand car.

The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a standard way to do it, but you should think about 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.

Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins of the key switch from current and stop them from being shorted. The diode will only allow the flow of current to be in one direction, and it has a black band visual indicator that indicates which way the current will flow.

Sanabria says that a few of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore the immobilizer's 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 a set in their trunk to jump-start a vehicle in an emergency, but it may not be the best option for vehicles with newer technology. These vehicles are equipped with numerous digital and computer systems that communicate with each other. A surge in voltage while the battery is connected to another battery could fry these components, rendering your car undriveable.

Start the working vehicle and allow it to run for around two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled vehicle's hood. An engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks, which could ignite the gasoline in the engine compartment.

Once the cables are connected, start the vehicle that has been disabled and allow it to run for around five minutes before you disconnect them in reverse order. Be aware that the battery in the saab key fob 9-3 gets recharged when you drive, and it will take a while for the battery to come back to normal. 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 saab Keys keys aren't in the process of trying to steal the car.

Many Saab owners have only one key for their vehicle and if they lose it, they'll be charged. It's expensive to purchase keys and will require replacing the CIM or TWICE for older models. In the event of theft or other catastrophe, it is best to have a spare key. Even even if the key is "new" it will not function.

Most locksmiths aren't able to help with a single working key, and the dealer will charge you high prices to replace the computer in your car to make a new replacement. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a new key without replacing the entire system. This can save you a significant amount of money. It's also a lot cheaper than waiting until you lose your only key.
