7 Things About Saab Ignition Key Replacement You'll Kick Yourself For Not Knowing
Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer system that is based on a set of keys. A new transponder is required to allow the inclusion of an additional key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The issue is that this can be extremely expensive. Always keep an extra set of keys in your possession.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to car when it is inserted into the ignition. The car will then check the signal to determine whether it is the same as the one on the key. If the signals are in sync the car will then open and start. This is an excellent way to guard your car against theft.

Transponder keys are a favored feature in cars, but you must be aware that they're not as secure as classic keys made of metal. While the metal portion of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip contains a unique code that's programmed into a car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do this if the fob is equipped with a chip that is not modified that has been programmed to match it. If not, the car will refuse to accept the key and will not start.

It is essential to have a spare Saab key. This is especially true especially if you reside in a rural location where there are a lot of car thieves. You can obtain a replacement key for your Saab by going to the dealership and not paying their pricey costs. You can have a replacement key made on the spot for less than half the price you'd spend at an auto dealer.

Wired key

Saab cars are usually provided with two keys. If you have only 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 a new CIM and the locking cylinders replaced. This can be costly especially if purchasing a used car.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There's no standard way to go about it, however, you should plan how to connect and solder each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 column.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode permits current to only flow in one direction. It is equipped with a visible indicator that is black, that indicates the direction in which current will flow.


saab key code of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can help shop customers or even DIY users in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the procedure, making it much easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep an item in their trunk to jump start a car in case of emergency, however it might not be the best option for vehicles with newer technology. They have numerous computers and digital devices that communicate with each other. A voltage surge while the battery is connected to another one could damage these components and render your car undriveable.

Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the damaged vehicle. The engine block is a good option. Do not connect the black cable to the negative terminal on the dead battery, since it could spark an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, start the vehicle and allow it to run for around five minutes. Then, disconnect them in reverse. Remember that the battery on the Saab 9-3 gets recharged when you drive, so it will take a while for the battery to go back down again. It's a good idea to invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and a special program to convince it that your lost keys aren't attempting to steal the car.

Replacement Case

Saab owners usually only have one car key, and if it is lost, they will be charged. It's costly to add keys and will require replacing the CIM or TWICE for older models. In the event of theft or other catastrophe it is best to have a spare key. Even even if the key is "new", it will not work.

The dealer will charge you top dollars if you only have one working key. However, we can reset and re-program your computer's EEPROM to prepare it to accept the new key without having to replace the whole system. That can save you lots of money. It's cheaper to do this than waiting until you lose the only key.
