What Types of Keys Will This Machine Duplicate?

Our state-of-the-art machines can duplicate a wide variety of keys, including but not limited to:


  • Standard Car Keys: Often the simplest form of keys, these are the conventional metal keys that have been used for years. Although many newer cars use more advanced types of keys, plenty of vehicles still use this type. Our machines can quickly and accurately duplicate standard car keys for a fraction of dealership prices.

  • Transponder Keys: A transponder key is a car key with a chip inside that communicates with the car's ignition system. This type of key enhances security by ensuring that only the car's specific key can start the vehicle. We have the technology to duplicate transponder keys, ensuring the new key fob communicates seamlessly with your vehicle.

  • Laser Cut Keys: Also known as sidewinder or high-security keys, laser cut keys have a distinctive winding cut on the shank. The pattern is even more complicated to duplicate than standard car keys, thus offering an added level of security. We have the capability to duplicate these types of keys with precision.

  • Proximity Keys: A proximity key, or smart key, allows for keyless entry and ignition. These keys do not require physical contact with the car to work. Instead, they operate in proximity to the vehicle, allowing you to unlock or start the car just by having the key nearby. Our top-tier machines are fully capable of replicating these advanced keys.

  • Key FOBs: A key FOB, which stands for "frequency operated button," is a small security device with built-in authentication protocols. It typically provides access to the physical object it protects, such as a vehicle. With our specialized car key FOB & car remote replacement services in Naperville, you can get a duplicate FOB quickly and reliably, ensuring you always have access to your vehicle.
