Five Killer Quora Answers To Saab Ignition Key Replacement
본문
Saab Key Programming
saab key code cars built since about 1994 have an immobilizer feature that is based on codes for keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.
It can be costly. This is why you should always have a spare key at hand.
Transponder key
The transponder is a piece of key that has an electronic chip. This chip sends a signal when the key is put in the ignition. The car then checks the signal to see whether it is the same as the one that is in the key. If the signals are the same the car will be able to unlock itself and begin. This is a great way to protect your vehicle from theft.
Transponder keys could be an increasingly popular feature for automobiles, but they are not as safe as traditional metal keys. While the metal portion of a traditional key may be cut and copied the transponder is protected by an electronic chip. This chip contains an unique code that is encoded into the car's system to identify it.
When a saab ignition key key fob is used the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob has a non-modified chip that has been programmed to match the original. If not, the car will reject the key and not start.
It's crucial to ensure that you have an extra key for your Saab. This is particularly important for those who live in a rural area where there are many car thieves. The good thing is that you can get a replacement key for your Saab without needing to visit a dealership and pay the expensive prices that they demand. You can have a replacement key created on the spot for less than half of the cost you would spend at an auto dealer.
Wired key
Saab cars are usually delivered with two keys. If you only have one, it is a good idea to get an extra key fob as soon as you can in case you lose it, your car will require the replacement of a CIM unit, and the locking cylinders have to be replaced. This can be costly especially if buying a used car.
The next step is connecting the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a good deal of soldering. It's not a standard way to do it, but you need to think about how to route and connect each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It has five rows and 17 column.
After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode permits current to only flow in only one direction. It is equipped with a visible indicator with a black band that indicates which direction current will flow.
Sanabria states that a number of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO and IM508, can help customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the user through the procedure, making it simpler than replacing the computer in the vehicle.
Jump-starting the battery
A majority of people keep a set in their trunk to jump-start a vehicle in the event of an emergency, but it might not be a good option for vehicles with newer technology. These cars are equipped with a variety of digital and computers that communicate with one another. A surge in voltage when the battery is connected another could cause damage to the components making your car unusable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. 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 of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery as this could trigger a spark that ignites the gasoline in the engine bay.
After the cables have been connected, you need to start the vehicle and let it run for approximately five minutes. Then, disconnect them in reverse. Remember that the battery on the Saab 9-3 will be charged when you drive, so it can take a while to get the battery back to its original level. It is a good idea to purchase a spare fob as soon as you can, because 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 in the process of trying to steal the car.
Replacement Case
Saab owners typically only have one car key, and if it is lost, they'll be charged. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. It is recommended to have a spare key in the event of theft or any other catastrophe the best solution is to purchase an additional key as soon as you can. Don't purchase a used key even the case that it's "new." Keys that are claimed-new from aftermarket sellers will not work and are likely to fail at the crucial moment.
The dealer will charge you the most expensive dollars if you only have one working key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This could help you save a significant amount of money. It's also a lot cheaper than waiting until you lose the only key.
