Transponder Chip Keys
Transponder keys also known as key FOBs or chip keys (fobs which control your key), are one of the most commonly used kinds of car keys. They've been in use for more than two decades and are designed to prevent theft by sending an encrypted message to your car when it's inserted into the ignition.
Transponders are microchips that are embedded in the plastic cover on your car keys. When the key is inserted in a key FOB or ignition for your car, it transmits a low-level radio signal the vehicle's Engine Control Unit (ECU). The ECU recognizes the unique serial number of the chip and responds accordingly - If the signal matches it, the engine is able to start.
Transponder chips aren't impervious to theft, but they are an effective method of reducing auto thefts. The concept behind these types of keys for cars is actually quite old in the past, dating back to World War 2 era military aircrafts that utilized coded messaging to differentiate them from enemy planes.
A locksmith can make a duplicate transponder for you in the event that you're locked out and require a replacement. This procedure is more complicated than rekeying your regular key since the chip inside the new key needs to match the car's receiver system. For this reason, getting a duplicate transponder key from a dealer is typically more expensive.
Keys Laser Cut Keys
Laser cut car keys are cut with grooves on both sides, in contrast to mechanically cut keys that can only be turned in one direction. This makes them more difficult to duplicate and can only be inserted into the lock or ignition on either side. They are also known as sidewinder or transponder keys. They offer greater security in the event of theft and are an upgrade from the standard chip key/transponder key.
To create a laser key, the locksmith must first identify the cuts on the key fob in order to determine what type of blank needs to be used. Then, he must set up the key cutting machine to cut the key based on the original cuts. This requires the use of a key cutting machine that is more sophisticated than the wheel-based duplicators that are available in hardware stores.
While these are more expensive than regular keys, they do offer additional security for your vehicle. This is because the laser key is not able to be duplicated by the same machines that are used to make standard edge-cut keys. This prevents the practice of "key-jumping," where a key for a vehicle is programmed to work with different vehicles and allows it to unlock the door or start the engine. The keys can only be retrieved by an experienced locksmith or a dealership.
