If you do locate the key you lost attempt to identify it by looking at the code that is stamped on the bow of the key. This will help you determine if it's the right key for your seat.
audi advanced key seat memory , also referred to as chip keys or key FOBs (fobs that control your keys), are one of the most common kinds of car keys. They've been in use for more than 20 years and are designed to stop theft by sending a coded message when put into the ignition of your car.
Transponders are microchips that are embedded into the plastic cover of your car keys. When the key is put into a key FOB, or the ignition of a car, it broadcasts an extremely low-level radio signal (ECU) to the vehicle. The ECU detects the unique digital serial number of the chip and responds accordingly - should the signal match, the engine will start.
Transponder chips aren't foolproof, but they are a great way of reducing auto theft. The idea behind these types of keys for cars dates back to World War 2 military planes, which used codes to differentiate them from enemy aircraft.
A locksmith can make a duplicate transponder in case you're locked out and require a replacement. This procedure is more complicated than rekeying an ordinary key, however, because the chip inside the new key must be compatible with the car's receiver system. This is the reason why purchasing duplicate keys from a dealer can be more costly.
Laser Cut Keys
Contrary to standard mechanical cut keys that only allow the key to be turned in only one direction and only in one direction, laser cut car keys have grooves that are carved on both sides. They are more difficult to duplicate and can only be used in the ignition or lock from either side. Also known as sidewinder keys are a step above the standard transponder key/chip key and provide more security in the event of a theft.
To make a laser-cut key the locksmith first analyze the cuts on the key fob to determine what kind of blank must be used. The locksmith will then set up the key-cutting machine to cut the key in line with the original cuts. This requires the use of a key-cutting machine that is more advanced than the wheel-based duplicators available in hardware stores.
These keys are more expensive, but they provide greater security for your car. Laser keys are not duplicated using the same machines that make the standard edge-cut keys. This is to stop the practice of "key jumping," where a key is programmed to work on a variety of vehicles and permits it to turn the lock and even start the engine. In addition, these types of keys can only be retrieved through a dealership or a professional locksmith.
