Saab Key Programming
Saab cars manufactured since 1994 utilize an immobilizer system based on coded keys. A new transponder is required in order to enable the addition of a second key, and special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
The issue is that it can be very costly. This is why you should always keep a spare key in your possession.
Transponder key
The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car will then check the signal to determine whether it is the same as that of the key. If the signals are identical, the car will unlock itself and start. This is a great method to guard your car against theft.
Transponder keys can be an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. The metal component of the traditional key can be easily cut and copied, however transponders are protected by an electronic chip which protects it. The chip has an unique code that is embedded into the car's computer to identify it.
The car will recognize the Saab keyfob and permit it to be turned on. But, it's only able to do so if the key fob is equipped with a chip that is not modified that has been programmed to match it. The car will not start if the key is not programmed to match.
It is essential to ensure that you have a spare key for your Saab. saab key code is especially true if you live in a rural location where there are numerous car thieves. You can get a brand new key for your Saab by visiting the dealership, without having to pay their expensive cost. You can have a replacement key made on the spot at a fraction of what you would pay at an auto dealer.
Key for Wired
Saab cars typically come with two keys upon purchase. If you own only one, you should get an extra key as soon as you can. This is because if it's lost, the car will need a new CIM and the locking cylinders 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 toughest component of the project and it will require a lot of soldering. There isn't a standard way to do this, but it is essential to determine the routes you'll use to solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 columns.
After the columns and rows are soldered, it's the time to connect them to the key switches. To do this you must place an inverter over each pin on the key switch and then solder it. This will shield the pins on the key switch from current and also prevent them from being shorted. A diode allows the current to flow in a single direction, and has a an indicator of black color that shows the direction in which current will flow.
Sanabria states that a number of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO or IM508, can help shoppers or DIY customers to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.
Jump-starting the battery
Most people keep a few sets of jumper cables in their trunks to use in an emergency, but jumping a battery in newer automobiles might not be the best option. These cars are equipped with a variety of computers and digital devices which communicate with one another. A surge of voltage when batteries are connected to another battery could damage the components and render your vehicle unusable.
Start the working vehicle and allow it to run for around two minutes before connecting 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 have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of the affected vehicle. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery because it could spark a 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. The battery in your Saab 9-3 will be recharged as you drive. It will take some time for it to recharge again. It is recommended to purchase a second key fob, as soon as you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Saab owners typically 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 in the case of older models. In the event of theft, or any other catastrophe it is recommended to have a spare key. Even even if the key is "new", it will not function.
The dealer will charge you top dollar for only one working key. We can, however, reset and re-program your computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This could save you a significant amount of money. It's also less expensive than waiting until you lose your only key.
