What's Holding Back In The Saab Ignition Key Replacement Industry?
Saab Key Programming

Saab cars made from 1994 have an immobilizer system that relies on keys that are coded. A new transponder is required for addition of an additional key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

This can be expensive. It is always advisable to keep an extra set of keys at hand.

Transponder key

The transponder keys are keys with an electronic chip that sends a signal to the car when it is inserted into ignition. The car then examines the signal to determine if it matches the one that is in the key. If the signals are in sync the car will then unlock and start. This is a great way to avoid auto theft and keep your car safe from thieves.

Transponder keys can be an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. The metal portion of a traditional key can be easily copied and cut, but the transponder is protected by an electronic chip that safeguards it. The chip is a unique code that's programmed into the car's computer in order to identify it.

The car will recognize the Saab keyfob and allow it to turn on. The car will only recognize the key fob when it has an unmodified chip and has been programmed to match. Otherwise, the car will reject the key and not start.

It's crucial to ensure that you have a spare key for your Saab. This is particularly important if you live in a rural area where there are a lot of car burglars. The good thing is that you can find a replacement key to your Saab without needing to visit a dealer and pay the hefty prices that they charge. In most instances, you can get a new key made on-the-spot for less than half the price of what you would pay at a dealer.

Wired key

Saab cars usually come with two keys when new. If you only have one, you should get an additional key as quickly as you can. This is because, if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly especially if you're purchasing a used car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. It's not a common way to do it, but you need to determine how to connect and solder each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five rows and 17 columns.

Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from being shortened. A diode only allows current to flow in one direction, and it has an indicator of black color that shows the direction in which current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508, can help customers who are shopping or DIY users to program replacement keys and restore immobilizer information. The tools plug into the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump starting the battery

The majority of people have an item in their trunk to jump-start their car in case of emergency, however it might not be the best option for vehicles with newer technology. These vehicles are equipped with many digital and computer systems that communicate with one another. A voltage spike when a battery is hooked up to another can fry these components and leave your car undriveable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to 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 disabled vehicle. The engine block is an excellent option. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline that is in the engine compartment.

Once the cables are connected, you need to begin the car and let it run about five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 is recharged while you drive. It takes a while for it to return to its original state. It is a good idea to purchase a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that your lost keys are not trying to steal the car.

Replacement case

Saab owners usually have only one car key, and if that is lost, they'll be charged. The reason for this is that it's expensive to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In saab key fob of theft or any other catastrophe it is advisable to have an extra key. Even even if the key is "new", it will not function.

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