Saab spare key (thekeylab.co.Uk) Key Programming

Saab cars manufactured since 1994 feature an immobilizer system that relies on a set of keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this can be extremely expensive. This is why you should always keep a spare key in your possession.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car checks to see whether the signal matches with the one on the key. If the signals are in sync then the car will be able to unlock and begin. This is a great way to protect your car from theft.

Transponder keys are a favored feature in automobiles, but you should be aware that they're not as secure as classic metal keys. While the metal portion of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip has an unique 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 it is equipped with an unmodified chip and programmed to match. The car will not start in the event that the key has not been programmed to match.

It is essential to have a spare Saab key. This is especially true for those who live in a rural area with many car thieves. You can purchase a new key for your Saab by going to the dealership without paying their high costs.

Key for Wired

Saab cars are usually delivered with two keys. If you only own one, you should get an additional key as soon as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This could be expensive especially if purchasing a used vehicle.

The next step is connecting the wires for columns and row 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 do it, however, you should think about how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, place a diode on each key switch pin and then solder it. This will shield the pins that are used for key switches from current and keep them from being shorted. A diode permits current to only flow in only one direction. It features a visual indicator, a black band, that shows the direction in which the current will flow.

Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY users in some cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools connect to OBD ports and guide the user through each step, making the process easier than replacing the car's computer.

Jumpstarting the battery

Most people keep an item in their trunk to start a vehicle in an emergency, but it might not be the best idea for cars with more modern technology.

Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline inside the engine compartment.

After the cables have been connected, you need to begin the car and let it run for approximately five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will recharge while you drive. It will take some time for it to fall back. It's a good idea to invest in a spare key fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't trying to steal the car.
