Saab cars built from 1994 have an immobilizer system that relies on keys that are coded. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The problem is that this can be quite costly. This is why it is important to always have a spare key available.

Transponder key

The transponder can be described as a key equipped with an electronic chip. The chip sends a signal when the key is put into the ignition. The car then checks the signal to determine whether it matches that of the key. If the signals match the car will then unlock and begin. This is an excellent way to safeguard your car from theft.

Transponder keys are an increasingly popular feature in automobiles, but you should be aware they're not as secure as classic metal keys. While the metal component of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip has a unique code that's programmed into a car's computer order 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 a chip that is unmodified and programmed to match. Otherwise, the car will reject the key and refuse to start.

It's crucial to ensure that you have an extra key for your saab spare key. This is particularly important especially if you reside in a rural location where there are many car thieves. The good news is that it's possible to find a new key for your saab 9-3 key fob programming without needing to visit a dealership and pay the high costs that they charge. In the majority of cases, you can have an original key made on the spot at a fraction of the cost you'd pay at dealerships.

Key for Wired

Saab cars are typically delivered with two keys. If you only have one, it's recommended to purchase an extra key fob as soon as possible, because if you lose it, the car will require the replacement of a CIM unit, and the locking cylinders will have to be replaced. This can be expensive especially for used vehicles.

The next step is to wire the row and column wires to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There's no standard way to do it, but you must think about how to route and solder each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 columns.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place a diode on each key switch pin and solder it. This will shield the pins from current and prevent them from being cut off. A diode allows the flow of current to be in one direction, and it comes with a an indicator of black color that indicates which way the current will flow.

Sanabria states that some of the tools available in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 will assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.

Jumpstarting the battery

Most people keep a few sets of jumper cables in their trunks to use in an emergency however, jumping a battery for newer vehicles might not be the best choice. These vehicles are equipped with numerous digital and computer systems that communicate with each other. A surge in voltage when the battery is connected to another can fry these components and render your vehicle undriveable.

Start the vehicle you are using 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 of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface beneath the hood of the disabled vehicle. The engine block is an excellent alternative. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline inside the engine compartment.

Once the cables are connected, you can start the car and let it run for approximately five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to recharge again. You should purchase an additional key fob as soon as you can. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Saab owners usually only have one car key, and if it is lost, they will be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft or any other catastrophe it is best to have an extra key. However, don't purchase a secondhand key even it's "new." Claimed-new keys from aftermarket sellers will not be effective and are almost guaranteed to fail in the crucial moment.

Most locksmiths aren't able to help with a single working key, and the dealer will charge for the cost of replacing the computer in your vehicle to make a new replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement saab 9-3 key key without having to replace the entire system. That can help you save money. It's also less expensive than waiting until you lose the only key.
