This can be done by inserting a flathead screwdriver in the slot in the middle of the key fob. After a little work you will be able of splitting the key. Remotes The latest Saab cars don't use traditional keys made of metal for security. Instead, they utilize an immobilizer that works on the recognition of a specific chip that is embedded in each key. This is the reason a particular kind of key is required to unlock the car and insert it into the ignition. This is one of the primary motives for a smart Saab owner to always have a spare key on hand. The traditional metal keys are simple to copy however the problem is that the electronic portion of a key fob needs to be matched to a particular car to allow the key to work. This matching is done in the computer modules of the car, referred to as CIM (Column Integration Modul) or TWICE. The dealer will charge you an amount to replace the modules and then program a brand new one if you lose your sole key. Local locksmiths can modify the EEPROM chip inside your car computer to create a new key. This could cost you as much as 50% of what dealers charge.

Transponders A transponder is an electronic device in a key fob which emits a unique coded signal. It's part of the immobilizer to prevent thieves from using stolen car key to start the vehicle. The transponder signals are received by a detector near the ignition, which decodes the serial number of the transmission. If the numbers match the car's serial number, it starts. Transponder keys are used in most cars manufactured in the past two decades. They are also used on aircrafts. Air traffic control uses them to identify friendly aircraft through an encoded signal, IFF (Identification Friend or Foe). Certain aircraft have transponders in mode C or S, which transmit the identification codes and altitudes to ATC. They also provide collision avoidance systems. The metal components on the standard Saab Key are simple to duplicate. However, the microchip which communicates with the immobilizer can be difficult to duplicate. If you have one of these, it is very important to protect it. Every Saab owner must have two keys working. You will have to pay a substantial amount of money if you lose your only key. You'll need an extra computer module or a spare key and program the car to convince it that you are not trying to take it. Immobilizers Immobilizers provide another layer of protection to stop thieves from hotwiring your vehicle. They prevent the engine from starting without ensuring that the transponder on the key fob is in order. In addition to that, most cars with immobilizers will also have a warning symbol on the instrument cluster that shows that the key isn't within. If you lose your key fob, you'll need to visit an authorized dealer to get it removed and then get the replacement. These systems are built on encryption of the data that goes between the transponder and car's system. However, recent studies have discovered that these encryption sequences are too easy for computers to break. Hackers are able to bypass them by analyzing the messages that are sent back and forth over the CAN bus. These systems are more sophisticated than traditional immobilizers which use one fixed code. The newer versions have the ability to change or rolling codes to ensure they are secure. The issue with these is that hackers are still able to find ways to break the code, and then use the key to start your car. To address this problem the DST80 was created with a longer sequence that would make it harder to deduce. Researchers were also able get it to work. It's important that you always keep your keyfob in your pocket, even when not using it.
