Saab Key Programming

saab key replacement key fob repair (click here to read) cars made since 1994 have an immobilizer system based on coded keys. A new transponder is required for addition of a second key, as well as special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

It can be costly. You should always keep an extra set of keys on hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is inserted into ignition. The car will then check the signal to see whether it is the same as the one in the key. If the signals match the car will then unlock and begin. This is a great way to guard your car against theft.

Transponder keys could be a popular addition to cars, but they are not as secure as traditional keys made of metal. The metal component of a traditional key is easily cut and copied, whereas transponders have an electronic chip that safeguards it. The chip is equipped with an unique code that is programmed into the car's computers to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. However, it can only do so if the key fob has a non-modified chip that has been programmed to match it. The car will not start when the key isn't programmed to match.

The next step is to wire the wires of the column and row to the microcontroller. This is the most laborious aspect of the project and it will require lots of soldering. There is no standardized way to accomplish this, however it is important to think about the way you'll route and solder the columns and rows. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the rows and column are soldered together, it is time to connect the key switches. To do this, place a diode across each key switch pin and then solder it. This will shield the pins that are used for key switches from current and keep them from being shorted. A diode only allows current to flow in one direction, and it also has 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 stores -like the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in some cases programme replacement keys and recover lost immobilizer data, Sanabria says.

Jump-starting the battery

A lot of people keep the set in their trunk to start a vehicle in an emergency, however it might not be the best option for vehicles with newer technology. These cars are equipped with a variety of electronic devices and computers that communicate with one another. A voltage surge when a battery is connected to another battery could damage the components, rendering 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 the affected car. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal of the dead battery because it could spark an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected the disabled vehicle and let it run for approximately five minutes before you disconnect the cables in reverse order. Be aware that the battery of the Saab 9-3 gets recharged when you drive, so it may take some time for the battery to go down. It's a good idea invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince it that your missing keys aren't trying to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose it, they'll be charged. It's expensive to add a key and requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster it is recommended to have an extra key. Even even if the key is "new" it won't work.

The dealer will charge the highest dollars if you only have one working key. We can, however, reset and re-program your computer's EEPROM to accept the new key, without replacing the whole system. That can save you lots of money. It's also cheaper than waiting until you lose your sole key.
