Does Technology Make Saab Ignition Key Replacement Better Or Worse?
Saab Key Programming
Saab cars made since 1994 utilize an immobilizer system based on a set of keys. In order to add a second key, it requires an entirely new transponder and programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The issue is that this could be extremely expensive. This is why it is important to always have a spare key at hand.
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 in the ignition. The car checks to see whether the signal matches with the one on the key. If the signals match the car will then unlock and start. This is a great method to deter auto theft and keep your vehicle secure from thieves.
Transponder keys are a popular feature in automobiles, but you should be aware that they are not as secure as classic metal keys. The metal portion of a traditional key can easily be cut and copied, whereas a transponder has an electronic chip which protects it. The chip has a unique code that is embedded into the car's computer to identify it.
The car will recognize the Saab keyfob and permit it to turn on. The car will only recognize the key fob if the device has a chip that is unmodified and programmed to match. Otherwise, the car will reject the key and refuse to start.
It is essential to have an extra Saab key. This is particularly true for those who live in a rural area with numerous car thieves. You can get a brand new key for your Saab by visiting the dealership and not paying their high prices. In the majority of instances, you can get a new key made on-the-spot for less than half the price of what you would pay at dealerships.
Key for Wired
Saab cars usually come with two keys upon purchase. If you only own one, you should get an additional key as soon as you can. This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced. This can be costly particularly for used cars.
The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There's no standard way to go about it, but 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 to connect.
After the columns and rows are soldered together It is now time to connect the key switches. To do this you must place a diode across each pin of the key switch and solder it. This will shield the pins from current, and prevent them from being shortened. The diode allows current to only flow in only one direction. It has a visual indicator of a black line that indicates which direction current will flow.
Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY customers in certain cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.
Jump-starting the battery
A majority of people keep an item in their trunks to jump start a car in an emergency, but this might not be a good option for vehicles with newer technology. These vehicles are equipped with digital and computers that communicate with one another. A surge in voltage while the battery is connected to another can fry the components and render your car unable to drive.
Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of your disabled vehicle. The engine block is a great option. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite gasoline in the engine compartment.
Once the cables are connected, you should start the car and let it run for about five minutes. Then, disconnect the cables in reverse. Be aware that the battery of your Saab 9-3 is recharged when you drive, so it will take a while to get the battery down. It is recommended to purchase another key fob when you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

saab fob key replacement have one car key, and if it is lost, they will be charged. The reason for this is that it's costly to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a backup key in case of theft or any other catastrophe and the most effective way is to buy an extra key as soon as you are able to. Even when the key is "new", it will not work.
Most locksmiths can't help you if you have only one working key and the dealer will charge you high fees to replace the computer in your vehicle to make a new replacement. We can reset and reprogram the computer's EEEPROM in order for it to accept a new key without the need to replace the entire system. That can save you a significant amount of money. It's much cheaper than waiting until you lose your only key.
