Saab Key Programming

saab key fob repair cars produced since 1994 feature an immobilizer system that is based on keys that are coded. In order to add a second key, it requires a new transponder, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

This can be expensive. It is recommended to always have a spare set of keys at hand.

Transponder key

The transponder key is a key with an electronic chip that transmits a signal to the car when it is put into the ignition. The car will check to see whether the signal matches the one on the key. If the signals match then the car will be able to open and start. This is a great way to deter car theft and keep your car secure from thieves.

The metal component of a traditional keys can be easily cut and copied, however transponders have an electronic chip that guards it. The chip is a unique code which is programmed into the car's computer in order to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car will only recognize the key fob if it is equipped with a chip that is unmodified and programmed to match. Otherwise, the car would reject the key and not start.

The next step is to connect the wires of columns and row to your microcontroller. This is the most laborious part of the project and Saab Key Fob Repair it will require lots of soldering. There isn't a standard method to go about it, but you should plan how to connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 column.

After the rows and column are joined after which it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and stop them from being shorted. The diode will only allow the current to flow in a single direction, and it has a black band 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 -- can aid shop customers or DIY customers in certain instances create replacement keys and restore lost immobilizer information, Sanabria says. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

The majority of people have a set in their trunks to jump start a vehicle in the event of an emergency, however it might not be a good idea for newer cars. These cars have a variety of digital and electronic devices that communicate with each other.

Attach the other end to a clean, unpainted metal surface under the hood of the affected vehicle. The engine block is a great choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline inside the engine compartment.

Once the cables are connected the vehicle that has been disabled and let it run for about five minutes before you disconnect the cables in reverse order. Keep in mind that the battery on your Saab 9-3 is charged while you drive, so it may take some time for the battery to go down. You should invest in an additional key fob as soon as you can.

It is recommended to have a second key in case of theft or any other catastrophe and the most effective way is to buy an extra key as soon as you can. Even even if the key is "new", it will not work.

The dealer will charge the highest dollar for only one working key. However, we can reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the entire system. That can save you a lot of money. It's also cheaper than waiting until you lose the only key.
