Why some keys look different now
If you hold an old house key and a newer car key side by side, you may notice that the newer one has a wavy track milled into its flat side instead of sharp teeth along the edge. That track is the sign of a laser cut key, also called a sidewinder or internal cut key. The name suggests laser technology, but the cuts are made by a milling cutter, not by light.
Dimple keys are a close relative. Instead of a track, they have a pattern of round indentations pressed into the flat sides of the blade. Both styles belong to a general family of high security style keys, designed to hold more precise combinations and to resist casual copying.
You may meet them on vehicles, on newer residential deadbolts, on commercial doors, and on some padlocks. Recognizing the type is useful when you need a spare or a replacement, because it affects who can make the key and what equipment is needed.
The reason manufacturers moved to these designs is largely about precision. A milled track or a drilled dimple can be placed with tighter tolerances than a notch filed along an edge, which allows a larger number of unique combinations and a more consistent fit between key and lock. The change is gradual, and you will find all key types in use around Central Florida.
How an edge cut key works, for comparison
A traditional key has notches cut along one or both edges. Inside a pin tumbler lock, small spring loaded pins rest at varying heights. When the correct key slides in, each notch lifts its pin to the exact height needed so that the dividing line between the pins aligns with the edge of the cylinder, allowing it to turn.
This design is simple, durable and easy to copy. A duplicating machine can trace the edge of an old key and cut a new blank to match. That convenience is why edge cut keys have been used for generations, and it is also why they offer limited control over who makes copies.
If you want a clearer picture of the mechanism, how a pin tumbler lock works in plain words explains it step by step.
One drawback of edge cut keys is how easily the edge wears. In a humid climate, keys also tarnish and pick up grime, which adds friction. That is part of why many makers chose flat, internal cuts, since the track is somewhat protected from the abrasion of a pocket or a purse.
Compare this to the way a bike lock or a luggage lock can be opened by anyone who learns the pattern. Pin tumbler design, whether the key is cut on the edge or inside the blade, relies on exact heights. The only thing that really changes is how those heights are read from the key.
Knowing this removes some of the mystery. A modern key is a more precise version of an old idea, not a different kind of magic.

CallWhat a laser cut key does differently
A laser cut key has its cuts milled into the flat face of the blade, in a winding groove. The groove has varying depth along its length, and the lock follows that depth with sliders or pins that touch the groove instead of the edge. Because the cutting is internal, the key is often thicker and stiffer than a standard one.
The blade usually has a symmetrical profile, so it can be inserted either way up. This reversible design is convenient in the dark or when you are in a hurry, and it is common on cars.
Making these keys needs a milling machine with a small, precise cutter. A duplicator made for edge cut keys cannot follow an internal track, so a shop without the right machine cannot copy it, no matter how skilled the operator.
Some laser cut keys have a cut on both faces, and some have a different track on each side. If you look closely, you can spot the difference between a single track and a double track key. A shop will want to see both sides of your key before ordering a blank.
If you are unsure which type you have, lay the key flat on a table in good light, photograph both faces and the edges, and describe what you see. That description often identifies the family.
- The cut is a track on the flat face, not teeth on the edge.
- Many are reversible, so they enter either way up.
- They are often thicker and stiffer than ordinary keys.
- They need a milling cutter, not a standard duplicator.
- Some include a transponder chip in the head.
Dimple keys and their round indentations
A dimple key carries a pattern of shallow round pits drilled into one or both faces. Each pit corresponds to a pin or tumbler in the lock, and the depth and position of each pit encodes the combination. The lock reads the dimples when the key is pushed in.
These keys are common in higher grade residential and commercial locks. They can allow many more combinations than a simple edge cut, and because they require specialist equipment to cut, copies are harder to produce casually.
The cutter is a drill style tool that must be positioned with great accuracy. A small error in the position or depth of a dimple can stop the key from working, so the equipment and the operator both matter.
Dimple locks, in particular, have a reputation for strength, but the quality of the lock body still decides the real result. A poorly made lock with a dimple style key is not a high security lock simply because the key looks sophisticated. Judge the lock as a whole.
Padlocks sometimes use dimple style keys too, and they appear on gates and sheds where weather is harsh. Those locks still benefit from cleaning and appropriate lubricant, applied sparingly.
Why copying them is a different job
Copying a laser cut or dimple key calls for a code cutting or tracing machine built for the style, and for the correct blank. Blanks are specific to the key family and often to the lock maker. A shop may have a machine and not the blank, or the blank and not the machine, and either one stops the job.
Some versions of these keys are restricted. The blanks are controlled and copies need authorization from the lock owner. This is intended to keep keys from being duplicated without permission, and it may mean you are asked for identification or proof of ownership. The proof of ownership guide explains what that looks like.
The practical effect is that a brief trip to a general hardware store may not solve the problem. A locksmith with the appropriate equipment is more likely to succeed on the first visit.
Equipment for these keys is expensive, which is why fewer shops offer it. Do not be surprised if one place suggests another, or if a locksmith explains that a particular key requires an order from the maker. That is a sign of honesty rather than reluctance.
When a blank must be ordered, plan for a wait that depends on the supplier. Ask what is involved before agreeing, and keep any working keys safe until the new one arrives.
Car keys and the extra layer of the chip
Many vehicle keys are laser cut and also contain a transponder chip. Cutting the blade lets the key turn the door lock or the ignition, and the chip lets the car recognize the key and allow the engine to run. Both steps must be done correctly.
Remote head keys and smart keys can also include a laser cut emergency blade, often hidden inside the fob. If your smart key has a small blade you can slide out, it is usually for emergency door entry when the battery in the fob is low. The smart keys, remote head keys and plain blades guide sorts out these terms.
Availability and key type depend on the exact vehicle, so have the make, model, year and the VIN ready when you call. Never assume that a key type from one car applies to another.
If your smart key has a hidden emergency blade, test it on the door once, calmly, so you know where the slot is and how to use it. Many drivers have never needed it and are surprised to discover how it works only when the battery is dead.
Rental cars and visitor vehicles often have these keys, and losing one on a trip is expensive and stressful. The rental car lockouts for visitors guide gives practical steps.
Losing one: what changes
When you lose an edge cut key, a copy from another key or a duplicate by code is often possible. When you lose a laser cut or dimple key, the process depends on what records exist. If you still have another working key, copying is simpler. If you have none, the key may be generated from the lock itself or from a code.
For cars, losing every key is a particular situation. The all keys lost explanation outlines what that involves, and the lost every car key page speaks to someone in that spot right now.
A calm approach helps. Gather proof that you own the car or have authority over the property, write down the vehicle details, and call with the information in front of you.
Keep records. A note of the key type, the lock brand, the vehicle details and the date a copy was made helps the next person who works on your keys. Store it with your other household records, not on the key ring.
If you manage a property with these keys, a registered key card or an authorization letter may be required for copies. Ask what the maker requires before you need an extra key in a hurry.
Wear and care for flat, milled keys
Because the cuts of a laser cut key are internal, they wear differently from edge cuts. The track can fill with lint, dirt and old lubricant, especially if the key lives in a pocket. A clean key slides in more smoothly and protects the lock.
Do not use a key as a screwdriver, a bottle opener or a lever. These keys are stiff but they can bend or twist, and a small bend can ruin the alignment. If you notice a key does not look straight, stop using it and get a fresh copy made from a healthy original.
Keep a spare in a safe place. Because these keys are harder to replace, a spare is more valuable than for a simple edge cut key. The household spare key planning guide offers a structure for deciding who should hold what.
Lubricant can be tricky with milled tracks. A small amount of a lock specific product on the key, wiped off before use, is enough. Spraying heavy oil into the lock can attract grit and make the track sticky over time.
If a key starts to feel stiff, do not force it. Stop, clean it, and see whether the problem persists. A persistent problem points to the lock or to a worn key.
Security: what these keys do and do not do
People sometimes assume that a laser cut or dimple key makes a lock unbeatable. That is not accurate. These key styles offer more combinations and make casual copying harder, but a lock is more than its key. The door, frame, strike and installation all influence how secure an entry really is.
A strong key system paired with a weak frame still leaves a weak point. The strike plate screw guide and the lock grades explained page both help you think about the whole assembly.
The right expectation is that a better key type is a useful layer, not a complete answer.
A good lock paired with a good installation is the foundation, and the key style is the detail on top. If you want to dig deeper, the plain guide to deadbolt types and the guide on lock replacement or rekeying are helpful next steps.
Do not let a salesperson convince you that a fancy key alone solves your security. Ask about the door, the frame and the installation too.
Insurance conversations sometimes touch on key and lock quality. Keep the paperwork for any lock upgrade and note the key type, so you can answer simple questions without searching.
Choosing between key styles for a new lock
If you are buying a new lock and have a choice, consider how you will replace keys in the future. A common edge cut key can be copied almost anywhere. A restricted dimple key is controlled but may require a longer process to replace. Neither is wrong, but each has trade offs in convenience and control.
Households that lose keys often, or that share keys among many people, may prefer easy copying. Businesses and managed properties may prefer control. The restricted keyways guide discusses that balance.
Whatever you choose, record the key type and keep the receipt. That information helps the next person who works on your lock.
Think about future owners and tenants. A key type that is common and easy to replace is easier to hand over. A restricted system gives control but needs a paper trail. Weigh these when you choose.
Ask for an estimate of the whole job, including the blank, the cutting and any testing, before agreeing to proceed. A clear explanation of what is included avoids surprises and lets you compare options calmly.
How Orlando Locksmith approaches these keys
Call and describe the key, the lock or vehicle, and what happened. The team confirms that you have the authority to have the key made, explains the work and the price before starting, and tests the finished key with you at the lock.
If the key is for a vehicle, give the make, model, year and VIN. If it is for a building, describe the door and the lock brand if you know it. A photo of the key, front and back, helps the person on the phone recognize the style.
Be prepared to provide identification or proof of ownership. It is a routine step and part of protecting your property.
Questions people ask
Is a laser cut key the same as a sidewinder key?
Yes, in common use. Both names refer to a key with a winding track milled into the flat face of the blade instead of teeth along the edge. The term laser can mislead, since the track is cut by a milling tool. Many car keys and some house keys use this style.
Can any locksmith copy a dimple key?
Not every shop has the machine or the blank. Dimple keys need a specific cutter and the correct key family blank, and some are restricted to authorized orders. A locksmith with the right equipment can tell you whether yours can be made and what proof of authority is needed.
Why are laser cut car keys harder to replace than old keys?
The blade needs precise milling, and many also include a transponder chip that must be programmed to the vehicle. Both steps need equipment and the correct blank for the exact vehicle. Have the make, model, year and VIN ready so the right key can be identified.
Do these keys make my lock more secure?
They add useful layers by allowing more combinations and making casual copying harder. They do not secure the door by themselves. The frame, strike, door slab and lock quality all matter, so think of a better key type as one improvement among several.
My laser cut key bent slightly. Is it still safe to use?
A bent key can wear pins and sliders and may stick or break in the lock. Stop using it and have a replacement made from a good original or by code. Trying to straighten it at home can weaken the blade further.
Do I need identification to get a copy?
Often yes, especially for restricted or vehicle keys. A locksmith may ask for identification and proof that you own the vehicle or have authority over the property. It is a normal precaution that protects owners and tenants from unauthorized copies.
