Imagine this: you lost your spare car key. The dealership wants you to wait days and pay thousands. A friend says, “Just send a photo of your key and get a new one cut.” Sounds unreal, right?
Here’s the truth: with the right tech and a few good photos,
a pro can often cut a working car key blade from pictures. No long queues. No
towing. No panic. In this guide, I’ll show you—step by step—how Key by Photo
works, what it costs, when it’s smart to use, and how to send photos that
actually get you a key that turns.
We’ll keep it simple, clear, and practical. And yes—we’ll
answer security worries too.
Can a Car Key Really Be Cut From a Photo?
Short answer: Yes.
If you provide clear, accurate photos of your key’s blade
(the metal part with the cuts), a trained service can decode those cuts and cut
a new blade to match. This works best for many non-remote or flip-blade styles
and high-security (sidewinder/laser) blades—when the electronics/transponder
programming is handled separately.
What this is (and is not):
·
It’s about the blade pattern—the exact “ups and
downs” cut into the metal.
·
It’s not cloning the electronics or transponder
chip from a photo.
If your car uses a transponder (most cars since the
mid-1990s), you’ll still need programming so the engine will start. The blade
opens the door and turns the ignition, but the car won’t start unless the chip
is recognized.
Fast rule of thumb:
Blade from photo = possible with good images.
Chip programming = separate step after you get the cut
blade.
How Key By Photo Works (Step by Step)
1) You take 3 clear photos of your key
Place the key flat on a plain, light background (white paper
is perfect).
Make the blade (the metal cuts) the star of the photo—not
the plastic head or buttons.
Good, even light. No shadows. No glare. No blur.
Take multiple angles if the blade has sidewinder/laser
grooves.
The service checks image quality. If they can’t see the
cuts, they’ll ask for better pictures.
Tip: Review your own photos first. If you can’t see the cuts
clearly, they can’t either.
The images are run through software that “reads” the depths
and spacing of your key’s cuts.
A technician reviews the result before cutting.
4) A machine cuts the new blade
A code or depth is sent to a precision cutting machine.
The machine cuts a new blade to match your original.
5) You receive the blade (and then handle programming if
needed)
If your car needs a transponder chip, you’ll pair the new
key with the car.
Many locksmiths can program the chip and pair remotes. (Dealers can too, usually at higher cost.)
> Tip: If your original is worn, a “code-cut” blade from
a photo can actually work better than copying a worn key. You’re getting a
fresh, clean cut to spec.
The Photo
Rules You Must Follow (So Your Key Actually Works)
·
Think “ID photo” for a key. If the camera can’t
see the detail, the machine can’t cut it.
·
Plain background: White paper or a smooth light
table. No textures or patterns.
·
Make the blade clear: Fill most of the frame
with the metal part and its cuts.
·
Keep it flat: No bending, twisting, or holding
in the air.
·
Good lighting: Bright, even light. Avoid direct
glare on shiny blades.
·
No blur: Brace your arms or rest the phone on
the table to keep steady.
·
Show the whole blade: From shoulder to tip, both
sides if it’s a sidewinder/laser key.
·
No fingers, no keychains: They block details and
confuse the software.
> Pro move: Take 5–8 photos, then pick the best 3 where
every groove is tack-sharp.
What About
Transponders, Remotes, and Smart Keys?
Blade vs. Brain:
·
The blade turns the lock/ignition.
·
The transponder chip (hidden in the head/fob)
tells the car’s immobiliser “it’s me.”
·
The remote (buttons) locks/unlocks doors and
sets the alarm.
What Key By Photo can do:
·
Cut the blade from your photos.
What it can’t do from photos:
·
Program the transponder chip.
·
Pair the remote buttons.
·
Clone smart/proximity systems.
How to finish the job:
1.
Take your new blade and transponder-ready shell
(if needed) to a local auto locksmith for programming.
2.
Or use dealership programming (usually pricier).
> Most vehicles built from the mid-1990s onward have an
immobiliser. Blade + programmed chip = start and drive. Blade alone will often
unlock the door but not start the engine.
When Key By
Photo Is a Smart Choice (and When It’s Not)
Great fit for:
·
You lost your spare and want a backup blade
quickly.
·
Your original blade is very worn (a fresh
code-cut can be better).
·
You’re far from a dealer and want to save time.
·
You’re okay handling chip programming locally
afterward.
Maybe not ideal for:
·
Keys with heavy damage, deep rust, or bent
blades (photos won’t read cleanly).
·
Situations where you need a fully working,
programmed key today (locksmith might be faster).
·
Some very high-security or exotic vehicles with
restricted parts.
Costs: What
to Expect (Blade vs. Full Key)
Prices vary by blade style and region, but here’s a simple
way to think about it:
·
Standard cut blade: lower cost
·
High-security / sidewinder blade: higher cost
(needs special machine)
·
Programming fee (extra): paid locally to a
locksmith or dealer
Why a code-cut-from-photo blade can cost more than a quick
duplicate at a kiosk:
·
You’re paying for decoding software, manual
review, precision cutting, and (often) a service guarantee.
·
Many low-cost kiosks copy wear and errors; code
cutting aims for factory-correct.
·
Hidden value: Good providers include
recut/warranty if the first blade isn’t perfect. That support is worth it.
How Long
Does It Take?
·
Photo check: Immediate if your photos are sharp
(re-takes add time).
·
Cutting & dispatch: Often 1–2 working days.
·
Shipping: Depends on your location and courier.
·
Programming appointment: Your local locksmith’s
schedule.
If you’re in Joburg north (Fourways / Cosmo City / Lion
Pride / Honeydew), local programming help is usually same or next day with an
auto locksmith.
Real-World
Mini-Stories (Johannesburg Scenarios)
1) Randburg school run saver
Naledi drops her kids at school and realizes the spare key
is gone. She snaps three clear photos of her flip key blade on white paper by
the dashboard. Two days later, the new blade arrives. She pops to a nearby
locksmith in Ferndale to program the chip. School run back on track—no dealer,
no tow.
2) Honeydew high-security win
Michael’s Honda has a laser/sidewinder key. His original
looks fine, but turning the ignition is rough. He orders a code-cut blade by
photo. The new blade turns smooth because it’s to spec, not copying old wear.
He keeps the old one as a rainy-day spare.
3) Cosmo City quick backup
Tebogo’s only key is working, but he wants peace of mind. He
sends clear photos and gets a blade-only backup. He stores it safely at home.
If his main key fails, he already has a blade ready for quick programming.
Common
Mistakes (That Delay Your Key)
·
Blurry photos (the #1 delay)
·
Busy backgrounds (wood grain and tiles hide the
cuts)
·
Half the blade out of frame
·
Glare that washes out the grooves
·
Only one side of a sidewinder/laser blade
·
Trying to “fix” a bent blade in the photo (just
send what you have; we’ll advise)
Fix: Take 5–8 careful shots in bright, even light. Pick the
best 3 where the blade is tack-sharp.
Security
& Privacy: Is This Safe?
Good providers follow strict checks and ask for proof of
ownership before cutting. Why? Because a clear photo is powerful—it carries
your key’s “fingerprint.” Services should:
·
Verify you and your vehicle details when needed
·
Keep your images and codes secure
·
Never ship to unverified addresses if policies
require proof
Your part:
·
Only share key photos with a trusted provider.
·
Don’t post key photos on social media (yes,
people can copy from those).
·
Use a Faraday pouch for key fobs at home to
block relay theft (handy bonus tip for modern cars).
What If the
New Blade Doesn’t Work?
Reputable services stand behind the cut:
·
Free recut if the first one isn’t quite right
(after a short troubleshooting checklist)
·
Money-back guarantee if they can’t resolve it
·
Help confirming you’re using the right key blank
and inserting it fully into the ignition or door
> Remember: if the immobiliser isn’t programmed, the
blade may turn but the car still won’t start. That’s normal until the chip is
paired.
What Kinds
of Keys Work With Key By Photo?
·
Car keys with visible blade cuts (standard or
sidewinder)
·
Flip keys where the blade folds out
·
Emergency blades inside many smart keys/fobs
Not suitable (by photo alone):
·
House, padlock, boat, or motorcycle keys (most
services only do cars)
·
Hidden or fully concealed cuts you can’t
photograph clearly
·
Some restricted automaker systems or blank types
not available in the market
> Not sure? Send photos. If it’s not a match, we’ll tell
you fast so you don’t waste time.
DIY vs. Pro
vs. Dealership: Which Should You Choose?
Key By Photo (you + pro cutter):
·
Pros: Fast, from home, often cheaper than
dealer, factory-correct code cut
·
Cons: You’ll still arrange programming if needed
Auto Locksmith (mobile):
·
Pros: Comes to you, can cut & program same
visit, solves weird cases
·
Cons: Usually more than blade-by-photo, but fair
for the convenience
Dealership:
·
Pros: OEM parts, full programming tools
·
Cons: Usually the most expensive and can be
slow; may require towing if you have no key
Balanced approach that works well:
1.
Get the blade by photo (fast and affordable).
2.
Visit a local auto locksmith for programming
(quick appointment).
3.
Test everything—doors, ignition, start, remote
buttons.
Troubleshooting: Blade Turns Rough or Won’t Insert?
·
Check the blank: Is it the correct profile for
your car?
·
Try both sides: Some blades are symmetrical,
others are not.
·
Clean the lock: A quick puff of graphite lock
lube (not oil) can help sticky wafers.
·
Wiggle gently: Very old cylinders can be tight.
Don’t force.
·
Programming pending: If it turns but won’t
start, you still need the chip paired.
If it still feels wrong, send a photo of your original and
new blade side-by-side. A pro can spot a depth or spacing issue quickly and
sort a recut.
Safety Note: Don’t
Share Key Photos Publicly
A clear image can be enough to copy a blade pattern. Keep
your photos private. Only share them with a provider you trust, and use
official upload portals—not random email threads or social DMs.
Quick Checklist:
Perfect Key Photos

Should You
Use Key By Photo?
Use Key By Photo if you want:
·
A fast spare cut from home
·
A clean, code-accurate blade (better than
copying a worn key)
·
To save money vs. dealership prices

A fully programmed key in your hand today (call
an auto locksmith)
·
A key style that’s restricted, exotic, or not
photographable
Either way, you’ve got options. And now you know exactly how
it works.
