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

Saab cars manufactured since 1994 use an immobilizer that relies on a set of keys. The addition of a key requires a new transponder, as well as special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

The problem is that this can be quite costly. It is always advisable to keep an extra set of keys available.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. The chip transmits a signal when the key is placed in the ignition. The car then checks to see whether the signal matches the one on the key. If the signals are in sync the car will then unlock and begin. This is a great way to protect your car from theft.

Transponder keys are a popular addition to automobiles, but they are not as safe as traditional keys made of metal. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. This chip contains an unique code that is programmed into the 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. The car can only recognize the key fob if it is equipped with a chip that is unmodified and programmed to match. Otherwise, the car would reject the key and not start.

It's crucial to ensure that you have an extra key for your Saab. This is especially important especially if you reside in a rural region where there are many car thieves. G28 is that you can find a new key for your Saab without having to go to a dealership and pay the high prices they ask. In the majority of cases, you can have a new key created on-the-spot at a fraction of the cost you would pay at a dealer.

Wired key

Saab cars are typically delivered with two keys. If you only own one, you should purchase an additional key as soon as you can. This is because, if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is to wire the row and column wires to the microcontroller. This is the most tedious component of the project and will require lots of soldering. There's no standard way to go about it, but you need to plan how to route and connect each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 columns.

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


Sanabria states that some of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the user through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

A majority of people keep the set in their trunk to start a vehicle in the event of an emergency, but this might not be a good idea for vehicles that are newer. These cars are equipped with a variety of digital and computer systems that communicate with each other. A surge in voltage when a battery is hooked up to another can fry the components and render your vehicle unable to drive.

Start the working vehicle and allow it to run for around two minutes before connecting the cables to the non-working one. 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 underneath the vehicle's hood. An engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. Be aware that the battery in your Saab 9-3 is recharged when you drive, so it may take some time for the battery to come back down again. It's a good idea invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince it that your missing keys aren't in the process of trying to steal the car.

Replacement Case

Saab owners usually have only one car key, and if that is lost, they will be charged. It's expensive to purchase keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster, it is best to have an extra key. Even if the key is "new" it will not function.

The dealer will charge you the highest dollar if you have only one working key. We can, however, reset and reprogram the computer's EEPROM in order to prepare it to accept an alternative key without replacing the entire system. This can save you a great deal of money. It's less expensive than wait until you lose the only key.
