Where to get a replacement key made
You have three main routes: a dealership, a locksmith, or a big-box retailer that cuts keys. Each charges differently and takes different amounts of time. A dealership will program a key to your specific car but costs the most — typically $200 to $500 depending on the car's age and whether the key has a remote or chip. A locksmith usually charges $50 to $200 and can often cut and program keys on the spot, though not all locksmiths handle every car model. A retailer like Home Depot or Ace Hardware can cut a basic key for $2 to $10, but this works only for older cars without electronic locks or remote functions.
The right choice depends on what kind of key you need. If your car has a keyless entry remote, a push-button start, or a transponder chip (most cars made after 1995), you need either a dealership or a specialized automotive locksmith. If you have an older car with a straightforward mechanical lock, any of the three will work.
Key Takeaways
- Dealerships charge the most but are the safest choice for newer cars with chips or remotes, and they can order keys even if you have no original.
- Automotive locksmiths are faster and cheaper than dealerships for most cars and can often cut and program a key in one visit.
- You will need proof of ownership — your title, registration, or insurance card — to get a key made at a dealership.
- A locksmith may ask to see your car in person to confirm the lock type and may charge a service call fee on top of the key cost.
- Big-box retailers can only cut basic keys for older cars without electronic locks.
What to bring to a dealership
Dealerships require proof that you own the car before they will make a key. Bring your vehicle title, current registration, or insurance card — any one of these will work. You will also need a photo ID. Some dealerships ask you to bring the car itself so they can confirm the VIN and lock type, though many will do this over the phone if you have your registration handy.
Call the dealership's parts or service department first. Tell them you need a replacement key and ask what documents they want you to bring. Some dealerships can order a key and have it ready in a few hours; others take one to three business days. Pricing varies widely by manufacturer — a Toyota key costs far less than a BMW key — so ask for a quote before you commit.
How a locksmith finds your key code
A locksmith does not need the original key because they can read the lock itself. They will either decode the lock by hand (looking at the pins inside) or use a machine that reads the lock's pattern. This takes 15 to 30 minutes. Some locksmiths will ask you to meet them at your car so they can examine the lock in person; others can work from a photo or your car's VIN if they have experience with your model.
Once they have the code, they cut a new key blank and test it in your lock. If your car has a transponder chip or remote, they program it using a machine that communicates with your car's computer. This step takes another 15 to 30 minutes. The whole process usually takes one to two hours and costs $75 to $200 depending on your location and the key type.
When you need the VIN to get a key
Your Vehicle Identification Number (VIN) is a 17-character code that identifies your specific car. You can find it on your registration, insurance card, or title. It is also stamped on the dashboard on the driver's side (visible through the windshield from outside) and on the driver's door jamb.
Some locksmiths and dealerships use the VIN to look up your car's key code in a database rather than decoding the lock by hand. This is faster and works well for common car models. However, not all cars are in these databases, and some locksmiths do not have access to them. If a locksmith says they need your VIN, ask whether they can also decode the lock in person as a backup — this gives you options if the database lookup fails.
Programming a key with a chip or remote
Cars made after the mid-1990s usually have a transponder chip in the key — a tiny computer that communicates with your car's ignition system. A key with a chip costs more to replace than a basic key, but it also prevents theft because a blank key will not start the car even if it fits the lock.
Programming a chipped key requires a machine that speaks to your car's computer. Dealerships have these machines built into their service bays. Most automotive locksmiths have portable programming equipment. Big-box retailers do not — if you need a chipped key, you must go to a dealership or locksmith.
If your key has a remote (for locking and unlocking from a distance), programming is more complex. Some dealerships can program a remote in 30 minutes; others send you to a specialist. Locksmiths vary widely in their ability to program remotes — ask before you commit. Remote programming usually costs $50 to $150 on top of the key cutting fee.
What happens if you have lost all your keys
If you have no original key at all, the process is the same, but you must prove ownership. A dealership will not cut a key without seeing your title or registration — this is a theft-prevention measure. A locksmith may be more flexible, but most will still ask for proof of ownership before they work on your car.
If you have lost your keys and your registration, you will need to go to your state's DMV or equivalent to get a replacement registration or title. This takes a few days. Once you have it, you can take it to a dealership or locksmith and get a key made. In the meantime, you can still drive the car if you have a spare key hidden somewhere, or you can call a towing service to move it.
Cost comparison: dealership vs. locksmith vs. retailer
| Option | Cost Range | Time | Best For |
|---|---|---|---|
| Dealership | $200–$500 | Same day to 3 days | Newer cars, remotes, when you want certainty |
| Automotive locksmith | $75–$200 | 1–2 hours | Most cars, when you need it fast and cheap |
| Big-box retailer | $2–$10 | Minutes | Older cars with mechanical locks only |
The cheapest option is not always the best. A locksmith is usually faster and cheaper than a dealership, but if your car is rare or very new, a dealership may be your only option. A big-box retailer is fast and cheap, but only if your car does not have a chip or remote.
Frequently Asked Questions
Can a locksmith make a key if the car is locked and I cannot get inside?
Yes. A locksmith can decode the lock from outside the car without opening it. They will examine the lock cylinder and either decode it by hand or use a machine to read its pattern. This takes 15 to 30 minutes and costs the same as making a key for an unlocked car.
What if the locksmith cannot program my key?
If a locksmith cuts a key but cannot program a chip or remote, they will tell you upfront. You can then take the cut key to a dealership to have it programmed, though you may pay a separate programming fee. Ask the locksmith whether they can refer you to someone who can program it, or whether the dealership will program a key that another shop cut.
Do I need the original key to get a spare made?
No. A locksmith can decode your lock and cut a new key without seeing the original. A dealership can look up your key code using your VIN and registration. The only time you absolutely need the original is if you want to copy it exactly — but that is rarely necessary.
How much does it cost to program a key with a remote?
Remote programming typically costs $50 to $150 on top of the key cutting fee. Some dealerships include programming in the key price; others charge separately. A locksmith may charge a flat rate that includes both cutting and programming, or they may charge separately. Always ask for a total price before you commit.
Can I program a replacement key myself?
For some older cars, yes — the owner's manual may include self-programming instructions. For most newer cars, no — you need a machine that communicates with your car's computer, which only dealerships and locksmiths have. Call your dealership or a locksmith to ask whether your car model supports self-programming.
