Spare Key Options

Spare keys are always cheaper than emergency replacements. Standard transponder duplicates start around $120. Smart key duplicates range from $200 to $350. We give you an exact price on the phone before any work starts.

01

Standard Metal Key Duplicate

Still running a traditional metal key with no chip? Getting a spare cut takes five minutes and saves you a tow bill later.

Standard metal key duplication is the simplest service we offer, but precision still matters. We use code-cut machines calibrated to factory depth and spacing specifications, not the worn-down pattern on your existing key.

$50โ€“$75~15 min

Get a precision-cut spare before you lose the only one.

02

Transponder Key Duplicate

Your key has a chip inside that talks to the engine. Without the right clone, the car won't start, no matter how perfect the blade cut is.

Every transponder key contains a small RFID chip embedded in the plastic head. When you turn the ignition, the car sends a radio challenge to the chip, and the chip responds with a cryptographic code. If the code doesn't match, the immobilizer kills the fuel injector circuit.

$125โ€“$225~25 min

Clone your transponder key today. No dealer wait, no markup.

03

Smart Key / Fob Duplicate

Down to one push-to-start fob? The dealer wants $400 or more and a week to order it. We program one at your location in half an hour.

Smart key duplication involves reading the vehicle's immobilizer system via the OBD-II port, generating a new cryptographic token, and writing it to a blank proximity fob. We use the Autel IM608 and VVDI Key Tool Plus to handle virtually every proximity protocol on the road: Toyota DST-AES, Honda HITAG3, Hyundai 128-bit AES, and Ford PATS.

$200โ€“$35030โ€“45 min

Add a spare smart key before your only fob walks away.

04

Flip Key Duplicate

That switchblade key that folds into your pocket? It has a cut blade, a transponder chip, and a remote module all packed into one housing. We duplicate all three on site.

Flip keys combine a folding metal blade with a transponder chip and usually a remote-control module for lock and unlock. Duplicating one means sourcing the correct shell and blank, cutting the blade on a machine that handles dimple or laser-track profiles, cloning or adding the transponder chip, and pairing the remote frequency.

$125โ€“$25025โ€“35 min

Duplicate your flip key while the blade and housing still work.

05

Laser-Cut Key Duplicate

Groove milled down the center of the blade instead of teeth on the edge? That's a laser-cut key, and most locksmiths don't carry the machine to cut one. We do.

Laser-cut keys, also called sidewinder or internal-cut keys, have a serpentine groove milled into the flat side of the blade rather than the sawtooth edge cuts of traditional keys. This design is standard on BMW, Mercedes, Ford, Jaguar, and many late-model vehicles.

$150โ€“$27530โ€“40 min

Get your high-security key duplicated by someone who actually has the right machine.

06

Valet / Backup Key Service

Need to hand someone the car without handing them access to your glovebox and trunk? That's what a valet key is for.

Valet keys are purpose-limited keys designed for situations where someone else drives your car but you want to restrict access. On older vehicles, the valet key physically cannot turn the glovebox or trunk cylinder. On newer vehicles with smart systems, a valet profile can be programmed that limits speed, disables certain storage compartments, and restricts infotainment access.

$100โ€“$20020โ€“30 min

Get a valet key cut for peace of mind when someone else drives.

Spare Key FAQ

Why is a spare key so much cheaper than an emergency replacement?
Because we have a working key to reference. We clone the chip data directly, cut the blade from the existing pattern or code, and program the duplicate alongside the original. When every key is lost, we have to decode the lock, extract the immobilizer PIN, generate a key from scratch, and register it with no reference point. More steps, more time, more tools, higher cost. A spare made now typically costs half of what an emergency replacement costs later.
Can I get a spare key without going to the dealership?
Yes. We use the same diagnostic platforms and OEM-spec blanks that dealers use. The key we make is functionally identical to a dealer key. The difference is we come to you, finish faster, and charge less because we don't have a service department with overhead markup.
Will making a spare key affect my existing keys?
On most vehicles, no. Adding a spare to the system doesn't erase existing keys. Some older vehicles do wipe the key memory during a programming session, which is why we always ask you to bring every working key. We program them all in the same session so nothing gets lost.
How many spare keys can my car hold?
Most vehicles accept up to eight transponder keys or proximity fobs in their system. Some older models cap at four. We can check your vehicle's capacity and tell you how many slots are currently used before we start.
Is a duplicate key as good as the original?
Functionally, yes. The blade is cut to the same depth and spacing, the chip is programmed with the same protocol, and the fob functions the same way. The only cosmetic difference might be the key shell if we use an aftermarket housing, but the performance is identical.
Can you duplicate a key that's already a copy?
We can, but we prefer to cut from the original manufacturer code rather than trace a worn copy. Tracing a copy of a copy introduces tiny blade deviations that accumulate over generations. If you give us the VIN, we pull the original bitting code and cut to factory spec regardless of what condition your current key is in.
How long does it take to get a spare key made?
Standard metal keys take about 15 minutes. Transponder keys and flip keys run 25 to 35 minutes because of the programming step. Smart fobs and laser-cut keys run 30 to 45 minutes. We give you the time estimate with your quote so you know what to plan for.
Should I get a spare key even if I have keyless entry and rarely use the physical blade?
Yes. The physical blade is your backup when the fob battery dies, the signal gets jammed, or the vehicle battery goes dead and the power locks stop responding. A spare fob is even more important because replacing a lost smart key from scratch is the most expensive key service we offer. Having a backup stored safely costs a fraction of an emergency replacement.
