Saab Key Programming Saab cars built since about 1994 have an immobilizer system 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 handled by the dealer using the Tech2 diagnostic tool. The problem is that this could be extremely expensive. This is the reason why you should always have a spare key on hand. Transponder key The transponder keys are keys with an electronic chip that sends a signal back to the 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 are in sync the car will then unlock and begin. This is a great way to avoid car theft and keep your vehicle safe from thieves. Transponder keys could be a popular addition to cars, but they're not as secure as traditional keys made of metal. While the metal component of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip has an unique code that is programmed into the car's computer 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 programmed to match. The car will not start in the event that the key is not programmed to match. saab 9-3 key fob replacement is vital to have an extra Saab key. This is especially important when you live in a rural location where there are a lot of car burglars. You can get a brand new key for your Saab by visiting the dealership without paying high cost. You can have a replacement key made on the spot for less than half of the price you'd pay at a dealership. Wired key Saab cars usually come with two keys upon purchase. If you have only one, it is recommended to purchase an additional key fob as soon as possible, because if you lose it, the car will require a new CIM unit, and the locking cylinders have to be replaced. This can be costly especially if buying a second-hand car. The next step is to connect the row and column wires to the microcontroller. This is the most laborious aspect of the project and will require lots of soldering. It's not a common way to do it, but you need to determine how to connect and solder each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 column. After the rows and column are soldered together It is now time to connect the key switches. To do this you must place a diode 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 permits current to only flow in only one direction. It has a visual indicator with a black band that indicates which direction current will flow. Sanabria says that some of the tools that are sold in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 are able to assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools plug into OBD ports and help the customer through each step and make the process more straightforward than replacing the car's computer. Jumpstarting the battery The majority of people have a set of jumper cables in their trunks for emergencies however, jumping a battery on newer vehicles might not be the best idea. These vehicles have many computers and digital devices that communicate with one another. A voltage spike when the battery is connected another could cause damage to the components and render your vehicle unusable. Start the working vehicle and let it run for about two minutes before connecting the cables to the one that is disabled. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood--the engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks, which would ignite the gasoline that is in the engine compartment. After the cables have been connected, you need to begin the car and let it run for approximately five minutes. Then disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is charged when you drive, and it can take a while for the battery to come back down again. You should purchase an additional key fob as soon as possible. Replacing the one that works requires the installation and programming of a brand new computer chip. Replacement Case Saab owners usually only have one car key, and if that is lost, they'll be charged. The reason for this is that it's costly to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is best to have a spare key in the event of theft or any other catastrophe, and the best way is to purchase a second key as soon as you can. Even when the key is "new" it will not work. The majority of locksmiths won't be able to help in the event that you only have one working key and the dealer will charge you top dollar to replace the computer in your vehicle to make a new replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without having to replace the entire system. This could save you a lot of money. It's less expensive rather than wait until you lose the only key.
