saab key fob programming Key Programming

saab 93 key fob cars made since 1994 come with an immobilizer system built on coded keys. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

It can be costly. This is the reason why you should always have a spare key on hand.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal back to the car when it is placed in the ignition. The car will check to see whether the signal matches with the one on the key. If the signals are the same it will open itself and start. This is a great way to guard your car against theft.

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

When a Saab key fob is used the car recognizes it and allows 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. In the absence of that, the car will reject the key and won't start.

It is essential to have an extra Saab key. This is especially true for those who live in a rural area where there are many car thieves. The good part is that you can find a replacement saab key key to your saab 93 key replacement without needing to visit an auto dealership and pay the expensive prices that they charge.

Wired key

Saab cars are usually supplied with two keys. If you only own one, you need to purchase an extra key as soon as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially for used cars.

The next step is to wire the column and row wires to the microcontroller. This is the most tedious aspect of the project and will require lots of soldering. It's not a common way to do it, but you must think about how to connect and solder each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from being cut off. The diode allows current to only flow in one direction. It features a visual indicator, a black band, that shows which way current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY customers in certain instances create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump starting the battery

The majority of people have a set in their trunk to jump start a vehicle in an emergency, but this might not be the best idea for vehicles that are newer. They have numerous computers and digital devices that communicate with each other. A voltage surge when the battery is connected to another one could cause damage to the parts making your car unusable.

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 to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface underneath the hood of the damaged vehicle. The engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite the gasoline inside the engine compartment.

After the cables have been connected, you can start the car and let it run about five minutes. Then disconnect them in reverse. Remember that the battery on the Saab fob key replacement 9-3 will be charged while you drive, so it may take some time for the battery to go down. It is a good idea to invest in a spare key 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 the system that your lost keys aren't attempting to steal the car.

Replacement case

saab keys replacement owners often only have one car key, and if that is lost, they will be charged. It's expensive to buy a key and requires replacing the CIM or TWICE in the case of older models. It's recommended to have a second key in case of theft or any other catastrophe the best solution is to purchase a second key as soon as you are able to. Even if the key is "new", it will not work.

The dealer will charge you the highest dollar if you only have one working key. We can, however, reset and re-program your computer's EEPROM to prepare it to accept the new key, without replacing the entire system. This could help you save a significant amount of money. It's also a lot cheaper than waiting until you lose the only key.
