Are The Advances In Technology Making Saab Ignition Key Replacement Better Or Worse?
Saab Key Programming
Saab cars made since 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
The problem is that this could be very costly. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder is a piece of key equipped with an electronic chip. This chip sends out a signal when the key is placed in the ignition. The car then checks to see if the signal matches the one on the key. If the signals match the car will then unlock itself and begin. This is a great way to protect your car from theft.
Transponder keys are a favored feature in automobiles, however you must be aware that they are not as secure as traditional metal keys. While the metal component of a traditional 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 the 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. But, it's only able to do this if the fob is equipped with a chip that is not modified that has been programmed to match. Otherwise, the car will reject the key and not start.
It is essential to ensure that you have a spare key for your Saab. This is especially important for those who live in a rural area with many car thieves. You can obtain a replacement key for your Saab by going to the dealership without paying high prices. You can have a replacement key made on the spot at a fraction of the price you'd spend at dealerships.
Key for Wired
Saab cars typically come with two keys when they're new. If you only have one, it is recommended to get an additional key as quickly as you can. This is because, if it's lost and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.
The next step is connecting the row and columns wires to your microcontroller. This is the most laborious part of the project, and will require lots of soldering. There's no standard way to accomplish this, but it is important to think about how you will route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins that are used for key switches from current and also prevent them from being shorted. A diode can only allow current to flow in one direction, and has a an indicator in black that indicates the direction in which current will flow.
Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY customers in certain instances create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it more simple than replacing the computer inside the vehicle.
Jump starting the battery
A lot of people keep a set of jumper cables in their trunks to use in an emergency however, jumping a battery on modern cars might not be the best choice. These cars have a variety of digital and computer systems that communicate with one another. A surge in voltage while a battery is hooked up to another can fry these components and leave your vehicle undriveable.
Start the vehicle that is working and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface under the hood of the affected 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 a spark, which would ignite the gasoline inside the engine compartment.
After the cables have been connected, you can begin the car and let it run about five minutes. Then, disconnect them in reverse. Be aware that the battery in your Saab 9-3 is charged when you drive, so it may take some time for the battery to come down. It's a good idea to invest in 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 it that your lost keys aren't trying to steal the car.
Replacement case
Many Saab owners only have one key for their car and if they lose it, they'll be charged. It's expensive to add keys and will require replacing the CIM or TWICE in the case of older models. It's recommended to have a backup key in the event of theft or any other catastrophe and the most effective way is to purchase an additional key as quickly as you can. Don't buy a secondhand key even the case that it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail at the crucial moment.
Most locksmiths can't help you when you only have one working key, and the dealer will charge top dollar to replace the computer in your vehicle to make a replacement. However, saab replacement keys uk can reset and re-program your computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This can save you a significant amount of money. It's less expensive instead of waiting until you loose the only key.
