Saab Key Programming

Saab cars that were built prior to 1994 feature an immobilizer mechanism made up of coded keys. A new transponder is required for the addition of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

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

Transponder key

The transponder is a key with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals match, the car will unlock and begin. This is a great way to avoid car theft and keep your car safe from thieves.

Transponder keys are a popular feature in automobiles, but you must be aware that they're not as secure as traditional metal keys. The metal portion of a traditional key can easily be cut or copied, while a transponder has an electronic chip which protects it. The chip is a unique code that is programmed into the car's computer in order to identify it.

When a saab key programmer key fob is used the car recognizes it and allows it to turn on. However, it will only do so if the key fob is unmodified and has a chip that has been programmed to match. In the absence of that, the car will refuse to accept the key and will not start.

It is crucial to have a spare saab keys key. This is particularly important for those who live in a rural area where there are a lot of car burglars. You can purchase a new key for your saab 93 key fob by going to the dealership, without having to pay their high costs. You can have the replacement key on the spot for less than half the price you'd pay at dealerships.

Wired key

Saab cars are typically delivered with two keys. If you have only one, it's recommended to purchase an additional key fob as soon as possible in case you lose it, your car will require a new CIM unit and the locking cylinders have to be replaced. This could be expensive especially if purchasing a used vehicle.

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 good amount of soldering. There's no standard way to accomplish this, however it is important to think about the route you'll take and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode how to open a saab 93 without a key each key switch pin. This will shield the pins from current and prevent them from being shorted. A diode can only allow current to flow in one direction, and it has an indicator of black color that indicates the direction in which current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 can assist shoppers or DIY customers to program replacement key for saab 93 keys and restore immobilizer data. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.

Jumpstarting the battery

The majority of people have a set of jumper cables in their trunks for emergencies however, jumping a battery for newer vehicles may not be the best option. These vehicles are equipped with numerous computers and digital devices which communicate with each other. A voltage surge while the battery is connected to another can fry these components and leave your vehicle undriveable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. 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 car's hood. The engine block would be a good 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 inside the engine compartment.

Once the cables are connected, you can start the vehicle you are not using and let it run for about five minutes before disconnecting them in reverse order. Be aware that the battery in the Saab 9-3 will be charged during your drive, which means it could take a while to get the battery back down again. It is a good idea to buy a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and a special program to convince it that your lost keys aren't trying to steal the car.

Replacement Case

Saab owners typically only have one car key, and if that is lost, they will be charged. It's expensive to purchase an additional key and it 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 even if the key is "new", it won't work.

The dealer will charge you the highest dollar if you only have one working key. We can, however, reset and reprogram the computer's EEPROM to accept an alternative key without replacing the whole system. That can help you save money. It's less expensive rather than wait until you lose the only key.
