Saab Key Programming
Saab cars that were built prior to 1994 come with an immobilizer system made up of coded keys. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
The issue is that this can be quite costly. This is why it is important to always have a spare key on hand.
Transponder key
The transponder key is a key equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals match it will open itself and begin. This is an excellent way to protect your car from theft.
Transponder keys could be an increasingly popular feature for cars, but they are not as secure as traditional keys made of metal. The metal component of the traditional keys can be easily cut or copied, while transponders are protected by an electronic chip that guards it. The chip has an unique code that is encoded into the car's system to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car won't start in the event that the key is not programmed to match.
It is crucial to have a spare Saab key. replacement saab key is especially true especially if you reside in a rural area where there are a lot of car thieves. The good part is that you can find a replacement key to your Saab without having to go to an auto dealership and pay the hefty prices they ask. In the majority of cases, you can have an original key made on the spot at a fraction of the cost of what you'd pay at dealerships.
Key for Wired
Saab cars typically come with two keys when they're new. If you own only one, it is recommended to get an additional key as fast as you can. This is because if it's lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly, especially for used cars.
The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There is no standard method to accomplish this, however it is crucial to plan the routes you'll use to solder the rows and columns. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 column.
After the columns and rows are soldered, it's the time to connect them to key switches. To do this, put an inverter over each pin of the key switch and solder it. This will shield the pins from current and prevent them from being cut off. A diode only allows the flow of current to be in one direction, and it has an indicator of black color that indicates the direction current will flow.
Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools connect to OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.
Jump starting the battery
The majority of people have a set of jumper cables in their trunks for emergencies, but jumping a battery on modern vehicles may not be the best idea. These vehicles are equipped with numerous digital and computer systems that communicate with one another. A voltage spike when the battery is connected to another battery could fry these components and render your car undriveable.
Start the vehicle that is working and allow it to run for around two minutes before you connect the cables to the non-working one. 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 of the black cable to an unpainted, clean metal surface underneath the disabled car's hood--the engine block is an ideal choice. Don't connect the black cable to the negative terminal on the dead battery, as it could ignite an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, you can start the car and let it run about 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 return to its original state. It's a good idea buy a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't trying to steal the car.
Replacement Case
Saab owners usually have only one car key, and if it is lost, they'll be charged. It's expensive to buy a key and requires replacing the CIM or TWICE for older models. It's best to have a second key in the event of theft or other disaster and the most effective way is to purchase a second key as soon as you are able to. Don't purchase a used key even it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail at the crucial moment.
Most locksmiths cannot 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, however, reset and re-program the computer's EEPROM in order to prepare it to accept the new key, without replacing the entire system. This could save you a great deal of money. It's more affordable instead of waiting until you lose the sole key.
