The Advanced Guide To Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since about 1994 have an immobilizer feature built on coded keys. A new transponder is required for addition of an extra key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
It can be costly. This is why you should always have a spare key available.
saab 93 key are keys with an electronic chip that transmits a signal to the car when it is put into the ignition. The car then analyzes the signal to see if it matches the one on the key. If the signals are in sync it will open and start. This is a great way to deter car theft and keep your vehicle secure from thieves.
Transponder keys are a common feature in automobiles, but you should be aware they're not as secure as traditional metal keys. The metal part of the traditional key is easily cut and copied, however transponders are protected by an electronic chip that protects it. The chip contains a unique code that is inserted 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 has been programmed to match. Otherwise, the car would reject the key and won't start.
It is important to have a spare Saab key. This is especially important especially if you live in a rural region that has many car thieves. The good part is that you can obtain a replacement key for your Saab without having to go to an auto dealer and pay the hefty prices that they demand.

This is because if it's lost and the car needs an entirely new CIM and the locking cylinders replaced. This could be expensive particularly if you are purchasing a used vehicle.
The next step is to wire the column and row wires to the microcontroller. This is the most difficult aspect of the project and will require lots of soldering. There is no standard method to accomplish this, however it is crucial to plan the route you'll take and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 column.
After the rows and column are soldered together after which it is time to connect the key switches. To do this, put an inverter over each key switch pin and solder it. This will protect the pins that are used for key switches from current and keep them from being shorted. A diode allows the current to flow in a single direction, and has a an indicator in black that shows the direction in which current will flow.
Sanabria says that a few of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 are able to assist shoppers or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to the OBD port and automatically guide the user through the process, making it more simple than replacing the computer inside the vehicle.
Jump starting the battery
The majority of people have the set in their trunks to jump-start a vehicle in the event of an emergency, but it may not be the best idea for newer cars. These vehicles have many electronic devices and computers that communicate with one another. A voltage surge while the battery is connected to another one could damage the components and render your car unable to drive.
Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface under the hood of the damaged vehicle. The engine block is an excellent alternative. Don't connect the black cable to the negative terminal of the dead battery, as this could trigger an ignition spark that ignites the gasoline in the engine bay.
After the cables have been connected, you can begin the car and let it run for about five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 will recharge as you drive. It takes a while for it to fall back. It's a good idea purchase a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.
Replacement Case
Saab owners usually only have one car key, and if it is lost, they'll be charged. It's expensive to purchase a key and requires replacing the CIM or TWICE in the case of older models. It is recommended to have a second key in case of theft or any other catastrophe the best solution is to purchase an extra key as soon as you can. Even it's "new", it won't work.
Most locksmiths cannot help you if you have only one working key, and the dealer will charge you high fees to replace the computer in your car to make a new replacement. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This could save you a great deal of money. It's also much less expensive than waiting until you lose your sole key.
