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

The problem is that this can be very expensive. This is why it is important to always have a spare key at hand.

Transponder key

The transponder key comes with an electronic chip that sends a signal back to the car when it is placed in the ignition. The car then analyzes the signal to determine whether it matches that of the key. If the signals are in sync then the car will be able to unlock and begin. This is a great method to safeguard your car from theft.

Transponder keys are a favored feature in automobiles, however it is important to know that they are not as secure as classic metal keys. While the metal portion of a traditional key can be cut and copied the transponder is protected by an electronic chip. The chip is equipped with an unique code that is programmed into the car's computer to identify it.

The car will recognize the Saab keyfob and allow it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and has been programmed to match. Otherwise, the car would reject the key and refuse to start.

If you have only one, it is recommended to purchase an additional key fob as soon as possible, because if you lose it, the car will require a new CIM unit and the locking cylinders will have to be replaced. This can be costly, especially for used cars.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most difficult component of the project and it will require a lot of soldering. There isn't a standard way to accomplish this, however it is important to think about the route you'll take and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the columns and rows are joined after which it is 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 cut off. The diode allows current to only flow in only one direction. It comes with a visual indicator of a black line that indicates which direction current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY users in some cases programme replacement saab key keys and recover the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the car's computer.

Jump starting the battery

Most people keep an assortment of tools in their trunks to start a vehicle in the event of an emergency, but it may not be the best idea for newer cars. They have numerous digital and computer systems that communicate with one another. A surge in voltage while the battery is connected to another could cause damage to the components and render your car undriveable.

Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood. The engine block is a good choice. Do not connect the black cable to the negative terminal on the dead battery because this could trigger an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you can begin the car and let it run for approximately five minutes. Then, disconnect the cables in reverse. Be aware that the battery in the saab ignition key 9-3 will be charged while you drive, so it will take a while for the battery to go back to normal. You should invest in an additional key fob as soon as you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

saab key fob replacement owners often only have one car key, and if that is lost, they will be charged. It's costly to add an additional key and it requires replacing the CIM or TWICE for older models. It's recommended to have a second key in the event of theft or other disaster, and the best way is to purchase an extra key as soon as you can. Don't buy a secondhand key even when it's "new." Keys that are claimed-new from a second-hand store will not perform and are almost certain to fail at the critical moment.

The dealer will charge the highest dollar for only one working key. We can, however, reset and re-program your computer's EEPROM in order to prepare it to accept the new key, without replacing the entire system. This could save you a significant amount of money. It's also much less expensive than waiting until you lose your only key.
