Car Key Duplication Cost by Make — Keller TX 2026 Price Table

"Can you just copy my car key?" is the most common question we get, and the honest answer is: it depends entirely on what is inside the key. A 1998 pickup key is a two-dollar piece of brass. A 2024 crossover key is a programmed security credential that has to be electronically introduced to the vehicle. Both are "duplicating a key." One costs about the price of a coffee, the other costs a few hundred dollars. Call or text (817) 968-3866 for a straight quote on yours.

Quick Answer

Car key duplication in Keller runs roughly $15–$40 for a plain mechanical key with no chip, $95–$220 for a transponder chip key, $140–$300 for a remote head key, and $200–$450 for a proximity smart key. The price is driven by the key's electronics and cutting method, not by the badge on the hood — but because certain makes use certain key types, the by-make table below is a reliable shortcut.

Duplication Cost by Key Type

This is the table that actually explains your price. Ranges as of August 2026, assuming you have one working key:

Duplication Cost by Make

Rough guidance for a spare made while your current key still works. Model year matters more than make within any single brand, so treat these as starting points rather than quotes:

Two structural notes. Luxury brands sit higher mostly because their fob hardware costs more, not because the labor is different — our Cadillac CT4 and CT5 key fob programming guide is a good example of where that premium actually goes. And within any brand, the base trim and the top trim of the same model year can use completely different key hardware — which is why we ask for the VIN rather than the badge.

Vehicles without a conventional key at all sit outside this table entirely. A card-based credential is duplicated through the manufacturer's own process rather than by cutting anything, and the pricing works differently — see Tesla key card replacement cost for how that path works.

Why the Hardware Store Copy Does Not Start Your Car

This is worth stating plainly because it costs people money every year.

A key-cutting machine at a big-box store copies the shape of your key. If your vehicle is roughly 1997 or older, shape is all there is, and that copy works perfectly. If your vehicle is newer than that, there is a transponder chip in the key head, and the vehicle's immobilizer checks for it before allowing the engine to run.

A copied blade with no programmed chip will do exactly this: unlock your doors, turn in the ignition, crank the engine, and then shut it off after two seconds. People conclude the copy was "cut wrong." It was cut fine. It just was not programmed, because the store has no equipment to program it.

The same applies to fob shells sold online. A replacement shell with your electronics moved into it works great. A brand-new fob with new electronics has to be registered to your specific vehicle before it does anything at all.

What Actually Drives Your Price

Whether you still have a working key. This is the single largest factor and it is not close. Duplicating from a working key is fast because the vehicle already trusts something. Starting from zero is an all-keys-lost job with a secure procedure, a longer appointment, and a materially higher price. Every vehicle in the table above roughly doubles in cost once the last key is gone.

The cutting method. Older keys use an edge cut a standard machine handles. Most vehicles since the mid-2000s use a high-security sidewinder or laser-cut profile requiring a specialized machine, which not every provider owns.

Fob hardware cost. A proximity fob is a small radio, and the part itself is a real cost. This is most of the gap between a $150 transponder key and a $400 smart key.

Programming complexity. Some platforms register a new key in five minutes. Others require a security access procedure with an enforced waiting period. Volkswagen's component-protection architecture, for example, is genuinely more involved than most — covered in our VW MQB component protection guide.

OEM Versus Aftermarket

Aftermarket fobs are typically 30 to 60 percent cheaper than dealer parts and, on most mainstream vehicles, work exactly as well. Where we recommend OEM is on newer luxury platforms and on any vehicle where the aftermarket options have a known reliability record we do not like. We will tell you which category yours falls into rather than defaulting to whichever is more profitable — our OEM versus aftermarket key fob breakdown goes deeper on the trade-off.

The Cheapest Time to Duplicate Is Right Now

Every all-keys-lost call we take started as a vehicle with exactly one key. The math is not complicated: a duplicate made today costs the numbers above. The same vehicle with no working keys costs roughly double, takes longer, and happens on whatever day is least convenient for you.

If any vehicle in your household is down to one key, that is the one to handle. Households with two or three vehicles should also know that doing them in a single visit is meaningfully cheaper than booking separate calls — you pay for travel time once.

How Duplication Works On-Site

1. VIN check on the phone. Determines key type, blade profile, and programming path, and lets us give you a real number instead of a range.
2. Ownership verification at the vehicle. Photo ID plus registration, title, or matching insurance. Required on every key job, no exceptions.
3. Cut the blade on the right machine for your profile.
4. Program the chip or fob to your vehicle's immobilizer using your working key to authorize.
5. Test everything — start, lock, unlock, panic, trunk, remote start if equipped.

Typically 20 to 45 minutes, at your home, office, or wherever the vehicle is parked in Keller, Southlake, Colleyville, Watauga, North Richland Hills, Haslet, Argyle, or Justin.

Frequently Asked Questions

How much does car key duplication cost in Keller TX?

From $15 to $40 for a plain mechanical key up to $200 to $450 for a proximity smart key, with transponder keys in between at $95 to $220. The electronics inside the key drive the price, not the make. Ranges as of August 2026.

Why will not a hardware store copy start my car?

Because the store copies the blade shape but cannot program the transponder chip your vehicle's immobilizer checks. The copy will turn the ignition and crank the engine, then shut it off after a couple of seconds.

Is duplicating a key cheaper than replacing a lost one?

Substantially — usually about half. Duplication uses your working key to authorize the new one. With every key lost, the vehicle requires a secure all-keys-lost procedure that takes longer and costs more.

Can you duplicate a key at my house?

Yes. Cutting and programming both happen at your vehicle, typically in 20 to 45 minutes anywhere in the Keller area.

Do I need proof of ownership to duplicate a car key?

Yes — photo ID plus registration, title, or matching insurance. Any locksmith willing to duplicate a car key without checking is one to avoid.

Should I buy a fob online and have you program it?

Sometimes that works and sometimes it wastes your money on the wrong part number. Send us the VIN before you order and we will tell you whether the fob you are looking at is correct for your vehicle.
