Saab Key Programming

Saab cars made since 1994 use an immobilizer system based on keys that are coded. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

It can be costly. This is why you should always have a spare key available.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is placed in the ignition. The car then checks the signal to determine whether it is the same as the one on the key. If the signals are identical, the car will unlock itself and start. This is a great way to guard your car against theft.

Transponder keys could be an extremely popular accessory for cars, but they're not as safe as traditional keys made of metal. The metal component of the traditional key can be easily copied and cut, but a transponder has an electronic chip that safeguards it. The chip is equipped with a unique code embedded into the car's computer to identify it.

When a saab replacement key programming key fob is used the car recognizes it and allows it to turn on. However, it can only do this if the fob has a non-modified chip that has been programmed to match it. The car won't start in the event that the key has not been programmed to match.

If you have only one, it's best to acquire an additional key fob as soon as possible in case you lose it the car will require an entirely new CIM unit, and the locking cylinders will have to be replaced. This can be costly particularly for used cars.

The next step is to wire the wires of the column and row to the microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. There is no standardized way to accomplish this, but it is essential to determine 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 pins and wires to connect.

After the columns and rows are soldered together after which it is time to connect the key switches. To do this, you need to place a diode on each pin on the key switch and solder it. This will protect the pins on the key switch from current and keep them from being shorted. A diode only allows the flow of current to be in one direction, and it comes with a an indicator of black color that shows the direction in which current will flow.

Sanabria says that some of the tools sold in auto parts stores, Saab Replacement Key Programming including the Autel MaxiIM IM608PRO and IM508 will assist customers shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and help the customer through each step, making the process easier than replacing the car's computer.

Jump-starting the battery

Most people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery on modern automobiles might not be the best idea. They have numerous digital and electronic devices that communicate with each other. A voltage spike when the battery is connected another battery could damage the components, rendering your car undriveable.

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 battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged vehicle's hood. An engine block is an ideal choice. Do not connect the black cable to the negative terminal of the dead battery as it could spark a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the car and let it run for about five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to fall back. It is a good idea to buy a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.

Replacement case

Many Saab owners only have one key for their car and if they lose that key, it will cost them. It's expensive to add a key and requires replacing the CIM or TWICE in the case of older models. It is recommended to have a second key in the event of theft or other disaster, and the best way is to purchase a second key as soon as you are able to. Even it's "new" it will not function.

Most locksmiths aren't able to help with a single working key and the dealer will charge you high prices to replace the computer in your vehicle to create a replacement saab 9-3 key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without the need to replace the entire system. This can save you a significant amount of money. It's less expensive rather than wait until you lose the sole key.
