saab key replacement Key Programming

Saab cars built since 1994 use an immobilizer system based on a set of keys. A new transponder is required for the addition of a second key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

This can be expensive. Always keep a spare set of keys available.

Transponder key

The transponder can be described as a key that has an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are the same the car will then unlock itself and begin. This is a great method to protect your vehicle from theft.

Transponder keys may be an increasingly popular feature for cars, but they’re not as secure as traditional keys made of metal. The metal component of a traditional key can be easily cut and copied, whereas transponders have an electronic chip that protects it. The chip is equipped with a unique code that is programmed into the car’s computers to identify it.

When a saab 9-3 key not accepted contact service key fob is used the car recognizes it and allows it to turn on. However, it will only do this if the key fob is unmodified and has a chip that has been programmed to match the original. The car will not start if the key is not programmed to match.

It is essential to have an extra Saab key. This is especially important for those who live in a rural region that has numerous car thieves. You can get a brand new key for your saab 900 key by going to the dealership, without having to pay their expensive cost. You can have a replacement key made on the spot at a fraction of what you would spend at a dealership.

Key for Wired

Saab cars usually come with two keys upon purchase. If you only have 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 a new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is to wire the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There isn’t a standard method to go about it, but you need to determine how to get a Saab replacement key to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.

After the rows and column are joined after which it is time to connect the key switches. To do this you must place a diode on each key switch pin and solder it. This will protect the pins from current, thus preventing them from being shorted. The diode allows current to only flow in one direction. It features a visual indicator with a black band that shows which way current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508, can help customers shopping or DIY customers to program replacement keys and restore immobilizer information. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the car’s computer.

Jumpstarting the battery

Most people keep the set in their trunks to jump-start a car in an emergency, however it might not be the best idea for newer cars. These vehicles are equipped with many digital and computers that communicate with each other. A voltage surge while the battery is connected to another battery could fry the components and render your car undriveable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have “POS” or “+” on it). Attach the other end to a clean, unpainted metal surface under the hood of your disabled car. The engine block is a good alternative. The black cable is not to 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, turn on the vehicle you are not using and allow it to run for around five minutes before you disconnect them in reverse order. Keep in mind that the battery on the saab key fob 9-3 gets recharged during your drive, which means it may take some time to get the battery back to its original level. You should invest in a second key fob, as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners only have one key for their vehicle and if they lose it, the cost will be. It’s expensive to buy an additional key and it requires replacing the CIM or TWICE in the case of older models. It’s best to have a backup key in the event of theft or other disaster and the most effective way is to purchase an extra key as soon as you are able to. Even it’s “new”, it won’t work.

The dealer will charge you top dollar if you only have one working key. However, we can reset and re-program the computer’s EEPROM to accept the new key, without replacing the whole system. This can save you lots of money. It’s more affordable than waiting until you lose the sole key.
