Saab Key Programming

Saab cars produced from 1994 have an immobilizer that relies on a set of keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

The problem is that it can be extremely expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. This chip sends out a signal when the key is inserted into the ignition. The car will check 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 a fantastic way to protect your car from theft.

Transponder keys are a common feature in automobiles, however you should be aware they're not as secure as traditional metal keys. While the metal component of a traditional key may be cut and copied the transponder 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.

The car will recognize the saab key fob repair keyfob, and allow it to be turned on. The car will only recognize the key fob when it has an unmodified chip and has been programmed to match. Otherwise, the car will reject the key and won't start.

Saab cars are usually supplied with two keys. If you only have one, it's recommended to purchase an extra key fob as soon as is possible, because if you lose it, the car will require a new CIM unit and the locking cylinders have to be replaced. This could be expensive particularly if you are purchasing a used vehicle.

The next step is to connect the wires for columns and row to your microcontroller. This is the most laborious part of the project, and it will require lots of soldering. There isn't a standard method to do it, but you must think about how to route and connect each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins of the key switch from current and keep them from being shorted. A diode only allows the current to flow in a single direction, and it comes with a the black band as a visual indicator that indicates which way the current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY customers in some cases replace keys in the program and restore lost immobilizer information, Sanabria says.

Jumpstarting the battery

A majority of people keep the set in their trunks to start a vehicle in an emergency, but it may not be the best option for vehicles with newer technology. These vehicles are equipped with digital and computers that communicate with each other. A surge in voltage when the battery is connected to another could cause damage to the components and render your vehicle unable to drive.

Start the vehicle that is working and let it run for about two minutes before you connect the cables to the one that is disabled. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface beneath the hood of the affected car. The engine block is an excellent alternative. Don't connect the black cable to the negative terminal on the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you should start the vehicle and let it run about five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to return to its original state. It's a good idea purchase a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and special programming to convince it that your lost keys aren't trying to steal the car.

Replacement Case

Saab owners usually have only one car key, and if that is lost, they'll be charged. The reason is that it's not cheap to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft or any other catastrophe, it is best to have an extra key. Even when the key is "new" it will not work.
