Is Technology Making Saab Ignition Key Replacement Better Or Worse?
Saab Key Programming

Saab cars that were built prior to 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

This can be expensive. This is the reason why you should always have a spare key on hand.

Transponder key

The transponder is a key equipped with an electronic chip. The chip transmits a signal when the key is placed in the ignition. The car then examines the signal to see whether it is identical to the one that is in the key. If both signals match, the car will unlock itself and begin. This is a great method to avoid auto theft and keep your car secure from thieves.

saab 93 key fob replacement are a popular feature in automobiles, but it is important to know that they are not as secure as classic metal keys. The metal component of a traditional keys can be easily copied and cut, but transponders are protected by an electronic chip which protects it. The chip has a unique code that is programmed into a car's computers in order 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 it is equipped with an unmodified chip and programmed to match. In the absence of that, the car will reject the key and refuse to start.

It is crucial to have an extra Saab key. This is particularly important when you live in a rural area that is home to many car thieves. You can purchase a new key for your Saab by visiting the dealership, without having to pay their high costs. You can get a replacement key created on the spot for less than half what you would spend at dealerships.

Key for Wired

Saab cars are usually provided with two keys. If you only have one, you should purchase an additional key as fast as you can. This is because if the key is lost the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if purchasing a used car.

The next step is to wire the row and column wires to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There's no standard way to do this, but it is important to think about the way you'll route and solder the columns and rows. There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this, place a diode on each pin of the key switch and solder it. This will shield the pins from current and prevent them from getting shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator with a black band that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY users in some cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

A lot of people keep an assortment of tools in their trunks to jump start a car in an emergency, however it might not be a good idea for newer cars. These cars have a variety of computers and digital devices that communicate with one another. A surge in voltage when a battery is hooked up to another battery could fry these components and leave your vehicle undriveable.

Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the disabled one. 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 clear, unpainted metal surface underneath the hood of your disabled car. The engine block is an excellent 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 the disabled vehicle and allow it to run for around five minutes before you disconnect them in reverse order. Remember that the battery on the Saab 9-3 will be charged during your drive, which means it will take a while for the battery to go back to normal. It's a good idea purchase a spare fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and a special program to convince it that your lost keys aren't in the process of trying to steal the car.

Replacement Case


Many Saab owners have only one key for their vehicle and if they lose it, the cost will be. The reason for this is that it's not cheap to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It is best to have a backup key in the event of theft or other disaster and the best option is to purchase an extra key as quickly as you can. Even even if the key is "new", it will not function.

The majority of locksmiths won't be able to help when you only have one working key and the dealer will charge high fees to replace the computer in your vehicle to create a replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without replacing the entire system. This could help you save a significant amount of money. It's also cheaper than waiting until you lose your one key.
