10 Things Everybody Hates About Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since 1994 use an immobilizer system that relies on a set of keys. A new transponder is required for inclusion of an additional key, and special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
saab keys is that this could be very expensive. Always keep a spare set of keys at hand.
Transponder key
The transponder key comes with an electronic chip that sends a signal to car when it is put into the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match the car will then unlock and start. This is a great method to safeguard your car from theft.
Transponder keys could be an extremely popular accessory for cars, but they're not as safe as traditional keys made of metal. The metal component of the traditional keys can be easily cut and copied, whereas the transponder is protected by an electronic chip that protects it. The chip is a unique code which is programmed into the car's computer in order to identify it.
The car will recognize the Saab keyfob and allow it to be turned 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 it. In the absence of that, the car will reject the key and refuse to start.
It's crucial to ensure that you have an extra key for your Saab. This is especially important for those who live in a rural area that is home to many car thieves. The good part is that you can obtain a replacement key for your Saab without having to go to a dealership and pay the high costs that they ask. You can get an original key made on the spot for less than half what you would pay at the dealership.
Key for Wired
Saab cars are usually supplied with two keys. If you have only one, it is best to acquire an extra key fob as soon as you can, because if you lose it, the car will require a new CIM unit and the locking cylinders will need to be replaced. This can be costly particularly for used cars.
The next step is connecting the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a standard way to do it, however, you should plan how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.
After the rows and column are soldered together after which it is time to connect the key switches. To do this you must place 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 lets current only flow in one direction. It has a visual indicator, a black band, that indicates which direction current will flow.
Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide the customer through each step which makes the process much easier than replacing the car's computer.
Jump-starting the battery
A lot of people keep a set of jumper cables in their trunks for emergency situations however, jumping a battery on modern vehicles might not be the most efficient option. These cars have a variety of digital and computer systems that communicate with each other. A surge of voltage when the battery is connected to another can fry the components and render your vehicle unusable.
Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged vehicle's hood. An engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite the gasoline inside the engine compartment.
Once the cables are connected the disabled vehicle and allow it to run for around five minutes before disconnecting the cables in reverse order. Remember that the battery on the Saab 9-3 gets recharged when you drive, so it will take a while for the battery to come back down again. It's a good idea purchase a spare fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your lost keys are not trying to steal the car.
Replacement Case
Saab owners usually only have one car key, and if that is lost, they will be charged. The reason for this is that it's not inexpensive to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is recommended to have a second key in case of theft or other disaster, and the best way is to purchase an extra key as soon as you are able to. However, don't purchase a secondhand key, even the case that it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are almost guaranteed to fail in the crucial moment.
The dealer will charge you the highest dollar if you have only one working key. However, we can reset and re-program your computer's EEPROM to prepare it to accept the new key, without replacing the whole system. That can save you a lot of money. It's also a lot cheaper than waiting until you lose your one key.
