Saab Key Programming Saab cars built since about 1994 have an immobilizer feature based on coded keys. A new transponder is required for inclusion of an additional key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool. It can be costly. Always keep a spare set of keys in your possession. Transponder key The transponder key comes with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car then checks the signal to see whether it is identical to that of the key. If the signals match the car will then unlock and start. This is a fantastic way to protect your vehicle from theft. Transponder keys could be an extremely popular accessory for automobiles, but they are not as safe as traditional metal keys. While the metal parts of a traditional key could be cut and copied the transponder is protected by an electronic chip. This chip contains a unique code 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 an unmodified chip and has been programmed to match. The car will not start when the key isn't programmed to match. It's essential to ensure that you have a spare key for your Saab. This is especially true especially if you live in a rural location that has many car thieves. You can get a new key for your Saab by visiting the dealership, without having to pay their pricey costs. You can get a replacement key made on the spot for less than half of what you would pay at a dealership. Key for Wired Saab cars usually come with two keys when they're new. If you only have one, you should purchase an additional key as fast as you can. This is because if it's lost the car will require a new CIM and the locking cylinders replaced. This can be costly especially if purchasing a used car. The next step is to connect the wires of columns and row to your microcontroller. This is the toughest part of the project and it will require lots of soldering. It's not a common way to do it, but you should consider how you will route and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect. After the columns and rows are soldered together It is now time to connect the key switches. To do this, put a diode across each pin of the key switch and then solder it. This will protect the pins that are used for key switches from current and keep them from being shorted. A diode only allows current to flow in one direction, and has a an indicator of black color that indicates the direction current will flow. Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY users to program replacement keys and restore immobilizer information. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the vehicle's computer. Jumpstarting the battery A lot of people keep the set in their trunks to jump-start a car in case of emergency, but it might not be the best idea for cars with more modern technology. These vehicles have many computers and digital devices that communicate with one another. A voltage surge when the battery is connected another one could cause damage to the parts making your car inoperable. Connect the cables to the vehicle working. 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 to a clean and unpainted metal surface under the hood of the damaged car. The engine block is a great choice. Do not connect saab 9-3 key fob replacement to the negative terminal of the dead battery, since this could trigger an ignition spark that ignites the gasoline in the engine bay. Once the cables are connected, start the vehicle and let it run about five minutes. Then disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is recharged while you drive, so it may take some time to get the battery back down again. You should purchase another key fob as soon as you can. The replacement of the one that works requires the installation and programming of a brand new computer chip. Replacement case Saab owners typically only have one car key, and if that is lost, they'll be charged. The reason is that it's expensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or any other calamity it is recommended to have a spare key. Don't purchase a used key even if it's new. Keys that are claimed-new from a second-hand store will not work and are likely to fail in the crucial moment. The dealer will charge you the most expensive dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a new key without the need to replace the entire system. This could save you a significant amount of money. It's cheaper to do this rather than wait until you lose the sole key.
