A key replacement is a time-consuming and expensive process. In addition to the cost of a new key you might have to get your vehicle towed and your car's computer chip repaired with the new key, which can be quite costly.

Transponder Chip Keys
The transponder key, also referred to as chip keys or key FOB (fob that controls your key) is among the more common types of car keys. They've been in use for over two decades and are designed to deter theft by sending an encrypted message to the car when it's put in the ignition.
Transponders are microchips embedded into the plastic cover on your car keys. When the key is placed into a key FOB or car ignition, it sends a radio signal that is low-level to the vehicle's Engine Control Unit (ECU). The ECU detects the unique serial number of the chip and responds accordingly - If the signal matches, the engine will start.

While transponder chips aren't foolproof however they are a great way to cut down on auto theft. breaking news behind these types of car keys is actually quite old-fashioned and dates to World War 2 era military planes that employed coded messaging to differentiate them from enemy planes.
If you're locked out and require the replacement key, a locksmith will easily make an identical transponder key for you. This process is a little more complex than rekeying an ordinary key, however, as the chip in your new key needs to be compatible with the receiver inside your car's system. Therefore, purchasing an identical transponder key from a dealer will typically be more expensive.
Keys Laser Cut Keys
Different from the traditional mechanical cut keys, which only allow the key to be turned in one direction and only in one direction, laser cut car keys have grooves carved out on both sides. This makes them harder to duplicate and can only be inserted into the lock or ignition on either side. Also known as sidewinder keys are a step up from the basic transponder keys/chip keys and offer more security in the event of a theft.
To create a Laser Key the locksmith first needs to decode the cuts from the existing key fob to determine the type of blank that should be used. Then, they must set up the key cutting machine to cut the key in accordance with the original cuts. This requires an equipment for cutting keys that is more advanced than the wheel-based duplicators that are available in hardware stores.
These keys are more expensive, but they offer greater security for your car. This is due to the fact that a laser key cannot be duplicated by the same machines that are used to make regular edge-cut keys. This prevents the practice of "key-jumping," where a car key is programmed for different vehicles, allowing it to open the lock or start the engine. These keys must be retrieved by an experienced locksmith or a dealership.
