Saab Key Programming

Saab cars made since 1994 feature an immobilizer system that is based on a set of keys. Adding an extra key requires a new transponder, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that it can be quite costly. This is why you should always have a spare key on hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals are the same it will open itself and begin. This is a fantastic way to safeguard your car from theft.

Transponder keys are a favored feature in vehicles, but it is important to know that they're not as secure as traditional keys made of metal. The metal component of a traditional key can easily be copied and cut, but transponders are protected by an electronic chip which protects it. The chip is equipped with an individual code that is embedded into the car's computer 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 the device has an unmodified chip and programmed to match. The car won't start if the key is not programmed to match.

It's important to make sure that you have an extra key for your Saab. This is especially true for those who live in a rural area, where there are many car thieves. You can obtain a replacement key for saab 93 key for your saab ignition key replacement by going to the dealership without paying their high prices. In the majority of cases, you can have an original key made on the spot for less than half the cost of what you would pay at the dealer.

Wired key

Saab cars are usually delivered with two keys. If you have only one, it's recommended to purchase an extra key fob as soon as you can, because if you lose it the car will require an entirely new CIM unit, and the locking cylinders need to be replaced. This can be costly, especially for used cars.

The next step is to connect the wires of the column and row to the microcontroller. This is the toughest component of the project and it will require a lot of soldering. There's no standard way to do this, but it is crucial to plan the way you'll route and solder the rows and columns. There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 columns.

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

Sanabria says that some of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 will assist customers shopping or DIY customers to program replacement Saab 9-3 Key keys and restore immobilizer information. The tools connect to the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery in newer cars might not be the best idea. These vehicles are equipped with digital and computer systems that communicate with one another. A voltage spike when the battery is connected to another could cause damage to these components, rendering your car unable to drive.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the non-working one. 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 affected car. The engine block is an excellent alternative. Don't connect the black cable to the negative terminal of the dead battery because this could cause a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle and let it run about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It may take a while it to fall back. It's a good idea to buy a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't trying to steal the car.
