Most car keys can be duplicated—including traditional metal keys, transponder keys, remote head keys, laser cut keys, and proximity smart keys. Basic mechanical keys are the easiest and quickest to copy, requiring only a key-cutting machine and a blank. These are common in older vehicles and basic trim levels.
Transponder keys, used in most cars built after the mid-90s, contain a chip that must be programmed to the vehicle’s immobilizer system. Laser cut and proximity keys are more advanced and require specialized tools. For a breakdown of these styles, check out our article on What Is Transponder Key? and What Is a FOBIC Key.
Duplicating a car key starts with identifying the key type and decoding the key’s cut pattern. For standard keys, it involves physically cutting a new blank. For electronic keys, the chip or remote needs to be programmed to your vehicle. Some vehicles allow onboard programming, but most require specialized locksmith tools or dealer software.
Advanced duplication requires laser key cutters, transponder cloning machines, and diagnostic programming tools. Mobile locksmiths use portable systems to decode key codes, clone chips, or program smart remotes. Many keys also require PIN retrieval, which can be done using vehicle-specific software. At Austin Key Replacement, we carry all these tools on-site for fast mobile service.

OEM keys are made by the vehicle manufacturer and are identical to what you’d get at a dealership. They usually come at a higher price. Aftermarket keys are made by third parties and are often more affordable while offering the same functionality. Some models, especially luxury brands, may only accept OEM keys due to software locks.
When in doubt, we help customers compare both options on-site and determine what’s best for their needs and budget. For official dealer key options, check Find a Car Dealer.
Some people attempt to duplicate keys using online kits or generic blanks, but most modern vehicles won’t accept unprogrammed chips or mismatched remotes. Proximity keys and smart remotes often require encrypted pairing via diagnostic equipment. Attempting DIY duplication can result in wasted time and money, or worse—lock you out of your vehicle’s security system.
For reliable results, use our Mobile Automotive Locksmith Services. We cut and program keys on-site, with guaranteed compatibility.
You can get a car key duplicated at a dealership, hardware store (for basic keys), or through a mobile locksmith. Dealerships may require appointments and vehicle towing.
