Keys lost or stolen
The replacement of a key is an expensive and time-consuming process. In addition to the cost of a new key you may need to have the vehicle towable and the computer chip of your car repaired with the new key, which can be very costly.
One way to save time and money is to ensure that you don't lose your keys in the first place. Consider placing a brightly colored or reflective piece of your keychain, or painting the bow of your key in a hue that stands out. It's also an excellent idea to keep the copy of your seat replacement key somewhere secure in case you lose the original.

Transponder Chip Keys
Transponder keys, also called key FOBs or chip keys (fobs that control your keys) are among the most common kinds of car keys. They've been in use for over two decades and are designed to deter theft by sending a coded message to your car when it's put in the ignition.
Transponders are microchips embedded in the plastic cover on 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 a unique serial number on the chip and responds in a manner that is consistent with the serial number. If the signal is in line, then the engine will begin to run.
Transponder chips might not be impervious to theft, but they are an effective method of reducing car thefts. The idea behind these kinds of keys for cars is actually quite old-fashioned in the past, dating to World War 2 era military planes that used coded messaging to distinguish them from enemy planes.
A locksmith can create an identical transponder for you if you are locked out and require a replacement. This process is a little more complicated than simply rekeying your standard key, however, since the chip in your new key needs to be compatible with the car's transponder system. This is why buying duplicate keys from a dealer can be more costly.
Laser Cut Keys Keys
Contrary to standard mechanical cut keys that only allow the key to be turned in one direction and only in one direction, laser cut car keys feature grooves carved out on both sides. They are more difficult to duplicate and are only put into the ignition or lock from either side. They are also referred to as sidewinder or transponder keys. They offer greater security in the event of theft and are an upgrade from the original chip key/transponder key.
To create a Laser Key the locksmith first needs to identify the cuts from the key fob that is already in place in order to determine the kind of blank that needs to be used. The locksmith then has to set up the machine that cuts keys to cut the key in accordance with the initial cuts. This requires a much more sophisticated key cutting machine than traditional duplicators that are based on wheels, which are found in hardware stores.
While seat car key battery cost more than a regular key they do offer additional security for your vehicle. This is because a laser key cannot be duplicated by the same equipment that is used to make standard edge-cut keys. This is a deterrent to "key-jumping," where a key for a vehicle is programmed to work with different vehicles, allowing it to turn the lock, or even start the engine. In addition, these types of keys can only be retrieved through a dealership or professional locksmith.
