Saab Key Programming

saab 9-3 key cars built from 1994 have an immobilizer system that is based on keys that are coded. A new transponder is required for the addition of an additional key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The problem is that this can be quite costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder is a key that has an electronic chip. This chip sends a signal when the key is put in the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are in sync then the car will be able to unlock and begin. This is a great way to stop car theft and keep your vehicle safe from thieves.

Transponder keys may be a popular addition to automobiles, but they are not as secure as traditional keys made of metal. While the metal component of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip has a unique code that's programmed into a car's computer in order to identify it.

The car will recognize the Saab keyfob and permit it to turn on. However, it can only do so if the key fob is unmodified and has a chip that has been programmed to match the original. The car won't start if the key is not programmed to match.

It's important to make sure that you have a spare key for your saab key. This is especially true for those who live in a rural region that has many car thieves. The good part is that you can find a new key for your Saab without having to go to an auto dealer and pay the hefty prices that they charge. You can get an original key made on the spot for less than half the cost you would pay at dealerships.

Key for Wired

Saab cars are typically delivered with two keys. If you only own one, you should purchase an extra key as soon as you can. This is because if the key is lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly particularly if you are buying a used car.

The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a great deal of soldering. There isn't a standard method to go about it, however, you should plan how to open a saab 93 without a key to route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the rows and column are soldered together then it's time how to get a saab replacement key connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being shorted. A diode allows current to flow in one direction, and it comes with a a black band visual indicator that shows the direction in which current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY customers in some cases programme replacement keys and recover lost immobilizer data, Sanabria says. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jump starting the battery

Most people keep an assortment of tools in their trunks to jump-start a vehicle in an emergency, but it might not be a good idea for newer cars. These vehicles are equipped with digital and computer systems that communicate with each other. A voltage surge while a battery is hooked up to another one could damage the components and render your car unable to drive.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, you can start the vehicle that has been disabled and let it run for about five minutes before you disconnect the cables in reverse order. Be aware that the battery in the Saab 9-3 gets recharged when you drive, and it may take some time for the battery to come back to its original level. It's a good idea to buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming to convince it that your lost keys aren't in the process of trying to steal the car.

Replacement Case

Saab owners often only have one car key, and if it is lost, they will be charged. The reason is that it's costly to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other disaster, it is best to have an extra key. Don't buy a secondhand saab Key Programming key, even the case that it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are almost guaranteed to fail at the critical moment.

Most locksmiths can't help you if you have only one working key and the dealer will charge top dollar to replace the computer in your car for a replacement. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept a new key without replacing the whole system. This can save you a significant amount of money. It's also cheaper than waiting until you lose the only key.
