Saab Car Key Replacement The majority of drivers will need to replace their Saab keys. Saabs require keys that are special and have chips that identify them. If you lose one of these cars, your car won't be able to start unless you have the other. But, you can save a lot of money by purchasing it yourself instead of paying the dealer. Keys The loss of your car keys or lost can be very inconvenient and stressful particularly if you only have one working key. Fortunately, this issue can be easily solved by a professional locksmith. AutoLocks Ltd can repair your SAAB keys quickly and effectively. G28 provide our services for 75 percent less than a dealer. The 03-11 SAAB owners face a unique issue with their car keys. Key fobs for these models tend to break easily and aren't robust. Many people don't own an extra one, which could be a safety risk in an emergency. You'll have to pay about $400 to the dealer if you want to add a second key. You'll need a brand new key, transponder, and to have the existing key programmed. The dealer will use the Tech-2 tool to complete this procedure. It is a simple process however you'll need mechanical skills to add the key. It is recommended to leave this to experts. The first step is to take the emergency key from the case. This can be accomplished by inserting a flathead screwdriver into the slot that is located in the middle of the key fob. After a few minutes of work, the key will split open. Remotes Modern Saab automobiles do not have metal keys to secure their vehicles. Instead, they utilize an immobilizer system built on recognition of the key and a specific chip embedded into every key. This is why a certain type of key is needed to unlock the car and insert it into the ignition. This is among the primary reasons for a wise Saab owner to always have a spare key in the car. The classic keys made of metal are easy to duplicate, but the real problem is that the electronic portion of a key-fob must be matched to a particular car in order for the key to work. This matching takes place in the car's computer module, which are called CIM (Column Integration Module) or TWICE (Theft Warning Integrated Central Electronics). If you lose your only functioning key and it costs the dealer a significant amount to replace these modules and program a new key. Local locksmiths can reprogram the EEPROM chip on your car computer to create a new key. This can help you save up to 50% of what a dealer would charge. We suggest you contact us as soon as you can when you lose your keys. This will help you avoid the expense of buying a new key from a dealer. Transponders A transponder is a chip in a key fob which transmits a unique, coded signal. It's a component of the immobilizer, which prevents thieves using a stolen car key to start the car. The transponder signal from the key are picked up by the receiver that is located near the ignition. The receiver decodes serial numbers that are generated by the transmission. If the number is in line, the car will start. Transponder keys can be found for the majority of automobiles manufactured in the last two decades. They are also used in aircrafts. ATC uses them to identify friendly aircraft with a coded signal, IFF (Identification of Friend or Foe). Certain aircrafts are equipped with mode C or mode S transponders that transmit identifying codes and altitude information to ATC. They also have systems for collision avoidance. The metal parts on the standard Saab Key are easy to duplicate. However, the microchip which communicates with an immobilizer could be difficult to duplicate. It is important to secure these keys if you own one. Every Saab owner must have two keys working. If you lose just one and you lose it, it will cost much to replace it. You'll need to purchase a computer module that is specifically designed for this or a spare key and program the car to convince it you are not trying to take it. Immobilizers Immobilizers add another layer of protection against hotwiring. They stop the engine from starting without ensuring that the transponder on the key fob is valid. Most cars with immobilizers also display a warning symbol in the instrument cluster, indicating that the key isn't inside. If you lose your keyfob, you will need to visit an authorized dealer to deactivate it and get a new one. These systems are founded on encryption of data that is transmitted between the transponder and the car's systems. Recent research has revealed that these encryption sequences can be accessed by computers. Therefore, they are able to be manipulated by hackers who can read the messages that are sent back and forward on the CAN bus. These systems are more sophisticated than conventional immobilizers, which use one fixed code. Newer versions use a system that alters or rolls codes to ensure that the systems are secure. The problem with these codes is that hackers still have the ability to discover ways to break the code and use a key to start your car. To address this issue, the DST80 has an extended code that makes it harder to figure out. Unfortunately researchers were able to crack this as well. Therefore, it's crucial to always keep your key fob in your purse when you're not using it.
