Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer feature that is based on codes for keys. In order to add a second key, it requires an entirely new transponder and programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that it can be extremely expensive. Always keep an extra set of keys available.

Transponder key

The transponder can be described as a key that has an electronic chip. The chip transmits a signal when the key is inserted into the ignition. The car then checks to see if the signal matches the one on the key. If the signals are identical the car will then unlock itself and begin. This is an excellent way to safeguard your car from theft.

Transponder keys are a common feature in cars, but you must be aware that they aren't as secure as traditional metal keys. While the metal part of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. This chip contains an unique code that is programmed into a car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do so if the key fob is unmodified and has a chip that has been programmed to match it. Otherwise, the car would reject the key and won't start.

It is essential to ensure that you have a spare key for your Saab. This is particularly important especially if you reside in a rural location where there are many car thieves. You can get a brand new key for your Saab by visiting the dealership and not paying their high costs. In the majority of instances, you can get a new key created on-the-spot for less than half the price of what you would pay at a dealer.

Wired key

Saab cars usually come with two keys when they're new. If you have only one, it's best to acquire an additional key fob as soon as possible, because if you lose it, the car will require an entirely new CIM unit, and the locking cylinders will need to be replaced. This can be costly especially if you're buying a used car.

The next step is to connect the wires for columns and row to your microcontroller. This is the most tedious component of the project and will require a lot of soldering. There's no standard way to do this, but it is crucial to plan the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode permits current to only flow in one direction. It features a visual indicator with a black band that indicates the direction in which current will flow.

Sanabria says that some of the tools sold in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508, can help customers who are shopping or DIY users to program replacement key for saab 93 keys and restore immobilizer information. The tools connect to OBD ports and guide the customer through each step, making the process easier than replacing the car's computer.

Jump starting the battery

A majority of people keep an item in their trunk to jump-start a vehicle in the event of an emergency, but it might not be the best idea for cars with more modern technology. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A voltage surge while the battery is connected to another battery could fry these components and render your car undriveable.

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

After the cables have been connected, you should start the vehicle and let it run about five minutes. Then, disconnect them in reverse. Keep in mind that the battery on the saab ignition key replacement 9-3 will be charged while you drive, so it can take a while for Saab Ignition Key Replacement the battery to go down. It is recommended to purchase an additional key fob when you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement case

Saab owners typically only have one car key, and if that is lost, they'll be charged. The reason is that it's not cheap to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is best to have a spare key in case of theft or any other catastrophe, and the best way is to purchase an additional key as early as you can. Don't purchase a used key, even if it's "new." Keys that are claimed-new from aftermarket sellers will not work and are almost guaranteed to fail in the most critical moment.

The dealer will charge you top dollar for only one working key. However, we can reset and re-program your computer's EEPROM to accept the new key without having to replace the entire system. This could help you save money. It's more affordable rather than wait until you lose your only key.
