Saab Key Programming
Saab cars built since 1994 use an immobilizer that relies on key codes. A new transponder is required for addition of a second key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
The problem is that it can be very expensive. This is why you should always have a spare key available.
Transponder key
The transponder is a piece of key equipped with an electronic chip. The chip sends a signal when the key is put into the ignition. The car checks to see whether the signal matches with the one on the key. If the signals are in sync it will unlock and begin. This is a fantastic way to guard your car against theft.
Transponder keys are an increasingly popular feature in vehicles, but it is important to know that they aren't as secure as traditional metal keys. While the metal parts of a traditional key can be cut and copied, a transponder is protected by an electronic chip. This chip contains an unique code that is programmed into a car's computer in order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if your key fob is equipped with a chip that is not modified that has been programmed to match it. If not, the car will reject the key and won't start.
It's essential to ensure that you have an extra key for your Saab. This is particularly important for those who live in a rural region that has numerous car thieves. You can purchase a new key for your Saab by visiting the dealership and not paying their expensive cost. You can get a replacement key made on the spot for less than half the price you'd spend at dealerships.
Key for Wired
Saab cars are typically delivered with two keys. If you own only one, you should purchase an additional key as quickly as you can. This is because, if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.
The next step is to connect the wires for the column and row to the microcontroller. how to get a saab replacement key G28CarKeys is the most challenging part of the project and will require a good deal of soldering. It's not a standard way to do it, but you should think about how to route and connect 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 time to connect them to the key switches. To do this, put an inverter over each pin on the key switch and solder it. This will protect the pins that are used for key switches from current and keep them from being shorted. The diode allows current to only flow in one direction. It is equipped with a visible indicator with 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 -- can help customers in the shop, or even DIY customers in certain instances create replacement keys and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep the set in their trunk to start a vehicle in an emergency, but it might not be a good idea for cars with more modern technology. These vehicles are equipped with many computers and digital devices which communicate with one another. A voltage spike when the battery is connected to another can fry the components and render your vehicle undriveable.
Start the working vehicle and allow it to run for around two minutes before connecting the cables to the non-working one. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the disabled car. The engine block is an excellent option. Don't connect the black cable to the negative terminal on the dead battery, as this could cause a spark that ignites the gasoline in the engine bay.
Once the cables are connected, start the disabled vehicle and allow it to run for around five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 will be recharged while you drive. It will take some time for it to fall back. It's a good idea buy a spare key fob as soon as you can, since replacing the sole working one requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.
Replacement Case
Saab owners often only have one car key, and if it is lost, they'll be charged. It's costly to add a key and requires replacing the CIM or TWICE for older models. It's best to have a second key in case of theft or any other catastrophe and the best option is to purchase an additional key as soon as you can. Don't buy a secondhand key, even when it's "new." Keys that are claimed as new from aftermarket sellers will not perform and are almost certain to fail at the crucial moment.
The majority of locksmiths won't be able to help in the event that you only have one working key and the dealer will charge you top dollar to replace the computer in your vehicle to create a replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key without replacing the entire system. This could save you a significant amount of money. It's also cheaper than waiting until you lose your one key.
