Saab Key Programming Saab cars manufactured since 1994 use an immobilizer system that is based on a set of keys. A new transponder is required for the addition of an extra key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool. thekeylab.co.uk can be costly. It is always advisable to keep a spare set of keys in your possession. Transponder key The transponder is a piece of key equipped with an electronic chip. The chip sends a signal when the key is put into the ignition. The car then analyzes the signal to see whether it matches the one on the key. If the signals match then the car will be able to unlock and start. This is a great method to avoid auto theft and keep your vehicle safe from thieves. Transponder keys are a favored feature in automobiles, however you should be aware that they're not as secure as traditional metal keys. The metal portion of a traditional key can be easily copied and cut, but a transponder has an electronic chip which protects it. The chip has an unique code that is embedded into the car's computer to identify it. The car will recognize the Saab keyfob and allow 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 won't start in the event that the key has not been programmed to match. It is important to have an extra Saab key. This is particularly important if you reside in a rural region that has numerous car thieves. You can get a new key for your Saab by visiting the dealership, without having to pay their expensive cost. In the majority of instances, you can get a new key created on-the-spot for less than half the cost you would pay at the dealer. Wired key Saab cars usually come with two keys upon purchase. If you have only one, you need to purchase an additional key as quickly as you can. This is because if you lose it, the car will need a new CIM and the locking cylinders replaced. This could be expensive, especially if you are buying a used car. The next step is to connect the wires for columns and rows to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There's no standard way to go about it, but you need to consider how you will route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect. Once the rows and columns are soldered, it's time to connect them to key switches. To do this, place a diode over each pin of the key switch and then solder it. This will protect the pins from current, thus preventing them from being shorted. A diode allows current to only flow in only one direction. It comes with a visual indicator, a black band, that shows the direction in which the current will flow. Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 — can assist customers at the shop or DIY customers in certain cases replace keys in the program and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and guide the customer 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 trunks to jump start a car in an emergency, however it might not be a good idea for cars with more modern technology. These vehicles are equipped with numerous electronic devices and computers that communicate with each other. A voltage spike when a battery is hooked up to another one could damage these components, rendering your vehicle undriveable. Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have “POS” or “+” on it). Attach the other end to a clear, unpainted metal surface underneath the hood of the disabled vehicle. The engine block is a good alternative. Don't 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. Once the cables are connected the vehicle you are not using and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in the Saab 9-3 will charge as you drive. It may take a while it to recharge again. It is a good idea to purchase a spare fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and special programming to convince it that your missing keys aren't in the process of trying to steal the car. Replacement Case Saab owners usually have only one car key, and if it is lost, they will be charged. The reason for this is that it's not inexpensive to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other catastrophe it is advisable to have an extra key. But don't buy a used key, even if it's “new.” Keys that are claimed as new from a second-hand store will not perform and are almost certain to fail at the critical moment. The dealer will charge you the highest dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without the need to replace the entire system. This could save you a lot of money. It's more affordable than wait until you lose the sole key.
