Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer mechanism made up of coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

It can be costly. Always keep an extra set of keys available.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal to car when it is put into the ignition. The car will then check the signal to determine if it matches the one in the key. If the signals match the car will then unlock and start. This is an excellent way to safeguard your car from theft.

Transponder keys may be a popular addition to cars, but they're not as safe as traditional metal keys. The metal component of the traditional key is easily cut and copied, however transponders have an electronic chip which protects it. The chip is equipped with an unique code that is programmed into the car's computers to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. The car won't start when the key isn't programmed to match.

It is essential to ensure that you have an extra key for your saab 9-3 key fob replacement. This is especially true especially if you reside in a rural area where there are a lot of car burglars. The good news is that it's possible to find a new key for your Saab without having to go to an auto dealership and pay the hefty prices that they demand. You can get the replacement key on the spot at a fraction of the cost you would spend at a dealership.

Key for Wired

Saab cars are typically delivered with two keys. If you only have one, it's an ideal idea to purchase an additional key fob as soon as you can as if you lose it, your car will require the replacement of a CIM unit and the locking cylinders will have to be replaced. This could be expensive especially if you're buying a second-hand car.

The next step is to connect the wires of the column and row to the microcontroller. This is the toughest part of the project and it will require a lot of soldering. There is no standard method how to program saab 9-3 key Fob; https://skou-lyons-3.technetbloggers.de/20-fun-informational-facts-about-saab-key-programming-1720699497, accomplish this, however it is essential to determine the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's the time to connect them to key switches. To do this, you need to place a diode across each key switch pin and then solder it. This will protect the pins from current and prevent them from being shortened. The diode allows current to only flow in only one direction. It comes with a visual indicator with a black band that shows the direction in which the current will flow.

Sanabria states that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508, can help customers shopping or DIY users to program replacement keys and restore immobilizer information. The tools connect to OBD ports and guide the user through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

Most people keep the set in their trunks to start a vehicle in the event of an emergency, but it may not be a good option for vehicles with newer technology. These vehicles have many computers and digital devices that communicate with one another. A surge in voltage when the battery is connected to another battery could damage the components making your car unusable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood--the engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery, since it could spark an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you need to start the vehicle and let it run about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 will recharge while you drive. It will take some time for it to return to its original state. You should invest in a second key fob, as soon as you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement case

Saab owners typically only have one car key, and if it is lost, they'll be charged. It's expensive to add keys and will require replacing the CIM or TWICE for older models. It's recommended to have a spare key in case of theft or other disaster and the most effective way is to purchase an additional key as quickly as you can. But don't buy a used key, even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't work and are likely to fail in the most critical moment.

Most locksmiths cannot help you with a single working key and the dealer will charge high fees to replace the computer in your car to make a new replacement key for saab 93. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a new key without replacing the entire system. This can save you a great deal of money. It's also much less expensive than waiting until you lose your one key.
