Saab Key Programming Saab cars manufactured since 1994 feature an immobilizer mechanism made up of coded keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool. This can be expensive. It is recommended to always have a spare set of keys in your possession. Transponder key The transponder key comes with an electronic chip that sends a signal back to the car when it is inserted into the ignition. The car then analyzes the signal to determine if it matches the one on the key. If the signals are in sync, the car will open and start. This is a great way to deter car theft and keep your vehicle safe from thieves. Transponder keys are an increasingly popular feature in automobiles, however you should be aware they are not as secure as classic metal keys. The metal part of the traditional key can easily be cut and copied, whereas transponders are protected by an electronic chip that safeguards it. The chip has a unique code that is embedded 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 if it has an unmodified chip and programmed to match. In the absence of that, the car will reject the key and not start. It's essential to ensure that you have a spare key for your Saab. This is particularly true when you live in a rural location that has numerous car thieves. saab key programming near me can obtain a replacement key for your Saab by visiting the dealership without paying their high cost. In the majority of instances, you can get an original key made on the spot for less than half the price of what you would pay at an auto dealer. Key for Wired Saab cars are usually provided with two keys. If you own only one, you should purchase an additional key as soon as you can. This is because if the key is lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used. The next step is connecting the wires of columns and row to your microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There is no standard method to accomplish this, however it is essential to determine the way you'll route and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 columns. After the rows and column are joined after which it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from being shorted. The diode allows current to only flow in one direction. It features a visual indicator with a black band that indicates which direction current will flow. Sanabria states that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer. Jump starting the battery A lot of people keep a set of jumper cables in their trunks for emergencies however, jumping a battery in newer vehicles might not be the best choice. These cars have a variety of digital and electronic devices that communicate with one another. A voltage spike when batteries are connected to another battery could damage the components, rendering your car undriveable. Start the working vehicle and let it run for about two minutes before connecting the cables to the disabled one. 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 underneath the hood of the disabled car. The engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery, since this could trigger an ignition spark that ignites the gasoline in the engine bay. Once the cables are connected, you should start the car and let it run for about five minutes. Then disconnect the cables in reverse. Keep in mind that the battery on your Saab 9-3 is charged during your drive, which means it could take a while for the battery to come down. It's a good idea to buy a spare key fob as soon as you can, because replacing the sole working one requires the installation of a brand new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car. Replacement case Saab owners usually only have one car key, and if it is lost, they will be charged. The reason for this is that it's costly to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended 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 quickly as you can. Even if the key is “new”, it will not work. The dealer will charge you top dollar if you only have one working key. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept a new key without replacing the whole system. This can help you save money. It's also cheaper than waiting until you lose your one key.
