Saab Key Programming

Saab cars produced since 1994 use an immobilizer system based on coded keys. To add an additional key, you need 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. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. The chip sends a signal when the key is placed into the ignition. The car will then check the signal to see if it matches the one in the key. If the signals match, the car will unlock itself and begin. This is a great way to deter auto theft and keep your vehicle secure from thieves.

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

The car will recognize the saab 93 key fob keyfob and permit it to turn on. However, it will only do this if your key fob is equipped with a chip that is not modified that has been programmed to match the original. The car will not start when the key isn't programmed to match.

It is essential to have an extra Saab key. This is especially important especially if you reside in a rural region where there are many car thieves. You can get a new key for your Saab by going to the dealership and not paying their expensive costs. In most cases, you can have an original key made on the spot at a fraction of the cost you would pay at a dealer.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There's no standard way to do it, however, you should think about how to route and solder each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It has 5 rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current, and prevent them from being shorted. A diode allows current to flow in one direction, and it also has a an indicator in black that indicates the direction in which current will flow.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk for emergencies, but jumping a battery in newer cars might not be the most efficient option. These vehicles have many electronic devices and computers that communicate with each other. A surge in voltage when a battery is hooked up to another could cause damage to these components, rendering your vehicle undriveable.

Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of your disabled car. The engine block is a great option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite the gasoline that is in the engine compartment.

Once the cables are connected, turn on the vehicle that has been disabled and allow it to run for around five minutes before disconnecting them in reverse order. Keep in mind that the battery on your saab 93 key fob 9-3 is charged during your drive, which means it may take some time for the battery to come back down again. It's a good idea buy a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and a special program to convince it that your lost keys are not trying to steal the car.

Replacement case

Saab owners usually only have one car key, and if it is lost, they'll be charged. It's expensive to buy keys and will require replacing the CIM or TWICE for older models. It is best to have a second key in the event of theft or any other catastrophe, and the best way is to buy an extra key as early as you can. But don't buy a used key, even when it's "new." Keys that are claimed-new from a second-hand store will not perform and are almost certain to fail at the critical moment.

Most locksmiths aren't able to help with a single working key, and the dealer will charge you for the cost of replacing the computer in your car to make a replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept an alternative key without replacing the whole system. This could save you a lot of money. It's much cheaper rather than wait until you loose the only key.
