Saab cars built from 1994 have an immobilizer system based on keys that are coded. To add an additional key, you need a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

This can be expensive. This is why you should always have a spare key available.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal to car when it is placed in the ignition. The car will then check the signal to see whether it is identical to the one on the key. If the signals are the same it will open itself and begin. This is an excellent way to protect your car from theft.

Transponder keys are an increasingly popular feature in automobiles, but you must be aware that they aren't as secure as traditional keys made of metal. The metal component of a traditional key can easily be cut or copied, while transponders have an electronic chip which protects it. The chip has a unique code that is programmed 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. However, it can only do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. The car will not start in the event that the key is not programmed to match.

It is crucial to have a spare Saab key. This is particularly important when you live in a rural location that has numerous car thieves. You can obtain a replacement key for your Saab by visiting the dealership, without having to pay their expensive costs. You can have an original key made on the spot for less than half the cost you would spend at dealerships.

Wired key

Saab cars are usually supplied with two keys. If you own only one, you should get an additional key as quickly as you can. This is because, if it's lost and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly, especially if you are buying a second-hand car.

The next step is to wire the column and row wires to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There isn't a standard method to go about it, but you need to determine how to route and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It has 5 rows and 17 column.

After the rows and column are soldered together It is now time to connect the key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and stop them from being shorted. The diode allows current to only flow in one direction. It comes with a visual indicator of a black line that shows the direction in which the current will flow.

A few of the tools that are available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in some cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump starting the battery

A lot of people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery in newer cars might not be the best option. These vehicles are equipped with numerous digital and computers that communicate with one another. A surge in voltage when a battery is hooked up to another battery could fry these components and leave your vehicle unable to drive.

Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. The engine block would be an excellent choice. Do not connect the black cable to the negative terminal on the dead battery as this could trigger an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you can begin the car and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in the saab key 9-3 will charge as you drive. It takes a while for it to fall back. It is recommended to purchase another key fob when you can. Replacing the one that works requires the installation and programming of a brand new computer chip.

Saab owners often only have one car key, and if that is lost, they'll be charged. It's expensive to buy an additional key and it requires replacing the CIM or TWICE in the case of older models. It's recommended to have a backup key in case of theft or other disaster, and the best way is to purchase an additional key as early as you can. Even even if the key is "new" it won't work.

Most locksmiths cannot help you if you have only one working key and the dealer will charge high fees to replace the computer in your vehicle to make a new replacement. We can, however, reset and re-program the computer's EEPROM to prepare it to accept a new key without replacing the entire system. This could save you a lot of money. It's more affordable instead of waiting until you lose the only key.
