Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer using a special Tech2 diagnostic tool.<br /><br />The problem is that this can be very expensive. You should always keep an extra set of keys in your possession.<br /><br />Transponder key<br /><br />The transponder key comes equipped with an electronic chip. It sends a signal to car when it is put into the ignition. The car will check to see if the signal matches the one on the key. If the signals are the same it will open itself and begin. This is a great method to avoid car theft and keep your vehicle secure from thieves.<br /><br />Transponder keys are an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal portion of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. This chip has an individual code that is encoded into the car's system to identify it.<br /><br />The car will recognize the Saab keyfob and allow it to turn on. However, it will only do this if the fob is equipped with a chip that is not modified that has been programmed to match it. If not, the car will reject the key and not start.<br /><br />It's crucial to ensure that you have an extra key for your Saab. [https://www.thekeylab.co.uk/saab-car-keys/ saab key programming] is especially important especially if you reside in a rural region where there are many car thieves. You can get a new key for your Saab by visiting the dealership, without having to pay their pricey costs. In most instances, you can get an original key made on the spot for less than half the cost you would pay at an auto dealer.<br /><br />Wired key<br /><br />Saab cars are usually supplied with two keys. If you only have one, it is a good idea to get an extra key fob as soon as you can as if you lose it the car will require a new CIM unit, and the locking cylinders will have to be replaced. This can be expensive especially for cars that are used.<br /><br />The next step is to wire the column and row wires to the microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There is no standardized way to do this, but it is essential to determine the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.<br /><br />After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and keep them from being shorted. The diode will only allow the current to flow in a single direction, and it also has a an indicator of black color that indicates the direction current will flow.<br /><br />Sanabria says that some of the tools sold 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 connect to OBD ports and guide the user through each step which makes the process much easier than replacing the car's computer.<br /><br />Jump-starting the battery<br /><br />The majority of people have a set of jumper cables in their trunks for emergency situations, but jumping a battery in newer automobiles might not be the best option. These vehicles have many computers and digital devices that communicate with one another. A voltage surge while the battery is connected to another could cause damage to these components and render your vehicle undriveable.<br /><br />Connect the cables to the vehicle working. Let it run for two minutes. 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 a clean, unpainted metal surface under the disabled car's hood. The engine block would be a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks that could ignite the gasoline in the engine compartment.<br /><br />Once the cables are connected, you should start the car and let it run for approximately five minutes. Then disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to drop back down. It is recommended to purchase a second key fob, as soon as you can. Replacing the one that works requires the installation and programming of a new computer chip.<br /><br />Replacement case<br /><br />Saab owners typically only have one car key, and if that is lost, they'll be charged. It's expensive to add keys and will require 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 work.<br /><br />Most locksmiths aren't able to help when you only have one working key and the dealer will charge you for the cost of replacing the computer in your car to make a new replacement. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a replacement key without having to replace the entire system. This could save you a great deal of money. It's also much less expensive than waiting until you lose the only key.<br /><br /> Summary: Please note that all contributions to Disgaea Wiki may be edited, altered, or removed by other contributors.
