Getting a Replacement Car Key
The Short Answer
You can get a car key made at a dealership or by an automotive locksmith. For some older, purely mechanical keys, a hardware store or key-cutting kiosk may also work. Which option fits depends on two things: the type of key your vehicle uses, and whether you still have a working key to copy.
Most modern vehicles use keys with an electronic component that must be programmed to the car. Cutting the metal blade alone is not enough for these keys. A freshly cut key may unlock the doors but still fail to start the engine. Expect to show proof that you own the vehicle before anyone makes a new key.
Why the Key Type Matters
Car keys have changed from simple cut metal into small security devices. The type of key largely determines who can make a replacement and how involved the job is. The exact key type depends on the make, model, model year and sometimes trim. Your owner's manual, or the dealer using your vehicle identification number (VIN), can confirm which one your car uses.
Key type | What it is | Who can typically make it; Mechanical key | A cut metal blade with no electronics | Locksmiths, dealers and some hardware stores or kiosks; Transponder key | A key with a chip that the car's immobilizer must recognize before the engine will run | Dealers and equipped automotive locksmiths; some kiosks can clone certain chips; Laser-cut (sidewinder) key | A thicker blade with a groove cut into its face rather than notches along the edge | Dealers and locksmiths with the right cutting machine; Remote key or switchblade fob | A key blade combined with remote lock and unlock buttons, usually with a transponder | Dealers and equipped automotive locksmiths; Smart or proximity key | A fob that allows keyless entry and push-button start without inserting a key | Dealers, and some automotive locksmiths depending on the vehicle
An immobilizer is an anti-theft system that only allows the engine to start when it detects a key it has been programmed to accept. This is why programming, not just cutting, is the central step for most replacement keys today.
Where to Get a New Car Key Made
Dealership: Can usually supply and program keys for the brands it sells, including newer or less common systems. You may need an appointment, and the vehicle may have to be at the dealership for programming. Automotive locksmith: Many cut and program transponder keys, remotes and some smart keys. Some offer mobile service, which helps if the car cannot be driven. Coverage varies by locksmith and vehicle, so confirm they can handle your make, model and year before booking. Hardware store or key kiosk: Practical mainly for mechanical keys, and for some transponder keys that can be cloned from an existing working key. They generally cannot help if every key is lost. Self-programming: Some vehicles allow an owner to add a key or remote through an onboard procedure, usually only when one or more working keys are already present. Whether this is possible depends on the make, model and year. The owner's manual is the place to check.
Proof of Ownership You Should Bring
Dealers and reputable locksmiths ask for proof of ownership because a new key gives full access to the vehicle. Exact requirements vary by business and state, so ask before you go. Commonly requested items include:
A government-issued photo ID; The vehicle's registration or title, with a name that matches your ID; The VIN, which appears on the registration and is usually visible through the windshield on the driver's side; The vehicle itself, if programming has to be done on site
If the car is leased, financed or registered to someone else, contact the provider beforehand. You may need additional authorization.
Copying a Key Versus Replacing All Lost Keys
If you still have a working key, getting another one made is usually simpler. The existing key can serve as a cutting pattern, and some systems allow a new key to be added or cloned from it.
If every key is lost, the job is more involved. The blade may need to be cut from a key code, which dealers can often look up by VIN. A new transponder or fob must then be programmed to the car. Depending on the vehicle, this may mean having the car towed to a dealer or calling a mobile locksmith who can work on site.
When keys are lost or stolen, ask whether the missing keys can be removed from the immobilizer's memory. This means a found or stolen key can no longer start the car.
What Affects the Cost
Prices vary too widely by vehicle, region and provider to state reliably here, so get quotes directly. The main factors that tend to raise or lower the price are:
The key type, with mechanical keys at the simplest end and smart keys at the most involved; Whether programming is required, and what equipment it needs; Whether you have a working key or all keys are lost; Whether you choose a dealer or a locksmith, and whether a mobile service call or tow is involved; Whether you buy an original-equipment key or an aftermarket key, since compatibility and quality can vary
Some roadside assistance plans, extended warranties or insurance policies may cover part of the cost of key replacement. Check your own coverage terms.
Steps to Get a Replacement Car Key
Identify your key type using the owner's manual or by asking a dealer with your VIN. Gather your proof of ownership: photo ID, registration or title, and the VIN. Contact a dealer and an automotive locksmith to confirm they can make and program your specific key, and compare quotes. Arrange for the vehicle to be available for programming, or ask about mobile service if it cannot be driven. Test the new key before leaving: lock, unlock, start the engine and check any remote functions. If keys were lost or stolen, ask to have them erased from the vehicle's system.
