11 Ways To Completely Revamp Your Saab Ignition Key Replacement Saab Key Programming

Saab cars produced since 1994 use an immobilizer system that is based on a set of keys. A new transponder is required for the addition of an additional key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

This can be expensive. You should always keep an extra set of keys in your possession.

Transponder key

The transponder keys are keys with an electronic chip that sends a signal to the car when it is put into the ignition. The car then analyzes the signal to determine whether it is identical to the one in the key. If the signals are in sync, the car will unlock and start. This is an excellent way to safeguard your car from theft.

Transponder keys could be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal component of a traditional key can be cut and copied the transponder is protected by an electronic chip. The chip has an individual 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 will only recognize the key fob if it has an unmodified chip and programmed to match. The car won't start when the key isn't programmed to match.

It's essential to ensure that you have an extra key for your Saab. This is particularly true especially if you live in a rural region that has many car thieves. You can get a new key for your Saab by going to the dealership and not paying their expensive prices. In most cases, you can have an original key made on the spot for less than half the price of what you would pay at the dealer.

Key for Wired

Saab cars typically come with two keys upon purchase. If you have only one, you should get an additional key as fast as you can. This is because if you lose it, the car will need 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 wire the row and column wires to the microcontroller. This is the most difficult component of the project and it will require a lot of soldering. There is no standardized way to do this, but it is important to think about the routes you'll use to solder the columns and rows. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After saab replacement keys uk and column are joined then it's time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current, thus preventing them from being shorted. The diode will only allow the current to flow in a single direction, and has a an indicator of black color that shows the direction in which current will flow.


Sanabria states that some of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 will assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump starting the battery

Most people keep an assortment of tools in their trunk to jump-start their vehicle in the event of an emergency, but this might not be the best idea for cars with more modern technology. They have numerous digital and computer systems that communicate with each other. A voltage surge while the battery is connected to another battery could fry these components and render your car undriveable.

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

Once the cables are connected, you can start the vehicle that has been disabled and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 is recharged as you drive. It may take a while it to recharge again. It is recommended to purchase 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 usually only have one car key, and if that is lost, they will 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, plus programming. It's best to have a backup key in case of theft or any other catastrophe the best solution is to purchase an additional key as soon as you are able to. Don't purchase a used key even when it's "new." Keys that are claimed as new from aftermarket sellers will not work and are likely to fail in the crucial moment.

The dealer will charge the highest dollar if you only have one working key. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept the new key, without replacing the whole system. This could save you a great deal of money. It's also a lot cheaper than waiting until you lose your one key.
