Why care?

Your neighbor’s kid can now copy your house keys using his 3D printer

Why care? Explained in 1 min
  • In the past high security keys could only be illegally duplicated by skilled thieves
  • Today even some of the highest security keys can be duplicated by 3D printing at home
  • What if I tell you that we bought the most expensive and secure systems available and that their 3D printed duplicates worked? Once printed, the duplicates can directly open your house lock (some even with a 1000CHF home 3D printer)
  • The issue is not the professional burglar breaking into your home, they can just use the windows. The problem is an ex-tenant, an ex-boyfriend/ex-girlfriend, an ex-housecleaning employee! No trace left behind
  • High security keys and their mechanical features have been compromised by 3D printing and 3D scanning by the masses
  • Even if you have a mechanical+electronic key, you should be aware that you only have one barrier left
  • Some lock manufacturers will tell you that the chip in the key solves the problem. Which is true, but the combination with electronic usually costs 500-700$ instead of 50$ and they bring convenience not security (do not forget the cumbersome annual change of battery). They are basically saying: “we did not deliver a secure mechanical system, so now you have to pay for our under performance”. Does not sound like a fair deal
  • The sense of security you paid for is now gone

Even some car keys

and Advanced keys too

The Stealth Key: unscannable security

The Stealth Key: Explained in 2 min

The Stealth Key – the ultimate security key

It cannot be simpler: a key which hides most of its mechanical security features internally – rendering the key unscannable. For millennia keys have relied on external features (yes, even the Egyptians and Romans used such keys), today thanks to 3D metal printing we turn the common house key inside out.


UrbanAlps is a multi-award winning high-tech startup based in Switzerland and developing the new standard of high security cylinder-locks and keys. A 3D printed metallic key which hides most of its mechanical security features internally During the last 2 years we have pushed hard to develop the first of its kind security system. Aiming at bringing the affordable solution against the 3D duplication threat.

We have developed a range of cylinder locks and un-scannable keys based on the Stealth Key concept. No matter how many pictures or home 3D scanners are used, it cannot be copied: the simplest and affordable key copy protection.

3D metal printing keys means…

  • Less waste: because only the material that is needed is used, there is less than 2% material wasted when producing the keys
  • Mass customization is free: each single key can be completely different at no extra cost
  • Factory layout is reduced to its minimum expression: one machine produces nearly all the steps needed
  • Complexity is free: it actually costs less to print a complex part instead of a simple cube of the same size
  • Localization is simple: needing only 1 machine to produce all sorts of keys means manufacturing can be kept at critical locations close to customer

Frequently asked questions


I do not care about the key being copied: the burglars will break the windows or the door…
The issue is not the professional burglar, but rather an ex-tenant, ex-girlfriend, ex-boyfriend, ex-cleaning employee….
Anybody can now easily duplicate high security keys.

Can somebody copy my key with just a picture?
Yes, if you have a simple key. That is what startups like key.me and keysduplicated.com make a living from.

How about the high security keys?
Those require to use a home 3D scanner to scan the key. In 2015 Intel integrated 3D scanners to phones and tablets. Apple will soon follow. Their motto: we live in a 3D world, you should be able to take 3D pictures of what you like.

But my key has movable parts that cannot be copied…
Unfortunately, keys with movable parts can also be copied.

But experts say that home 3D printers are not capable of printing a working key.
They are capable. We have used an Ultimaker 3D printer (<1000USD) among others and printed many of the existing keys.

But my key has also electronics, can it be copied?
The mechanical part can be copied, but the electronics will still avoid the lock from opening. You should be aware that you only have one barrier left and that the electronics are mostly for convenience rather than security. Actually, it is well known that RFID technology has also been compromised (the most common in key chips).  A determined attacker can purchase specialized equipment that can read and replay RFID cards.

There is already a solution: chip in the key!!
The electronic combinations are 3-4 times more expensive. For instance, a mechanical cylinder lock and keys costs circa 100-200$ in Switzerland, a combination of such system with electronics is in the 700-1000$ range. Do you want to be the one to pay because the lock manufactures did not deliver a secure mechanical solution? It is unfair that you pay for their under-performance.

My keys have magnets that cannot be copied.
Correct, but do you like magnets next to your credit cards and mobile phones? Furthermore, it is an expensive option and we believe that this is not the best solution.

My next lock will be operated through my mobile phone.
That solution exists since years, it is very cool and convenient. But it is neither reliable nor secure. Nobody believes that a phone is secure. Also think about the battery on the lock and on your phone. There is nothing that pisses off a customer more that not being able to get into his own house.
That is why 90% of locks sold worldwide are mechanical.

I am sure the 3D printed copy will break in the lock.
They do not, we have done it for 7 high security locks and the duplicates do not break.

I do not care if people copy my keys.
Fair enough. At UrbanAlps we help people who care about their security and their family. We want keys to be secure again, we want lockers at train stations to be safe again, we want people to feel safe while they are sleeping at home.

So what should I do about my keys?
1st step is to be aware that your keys can now be easily copied.

What do Insurance companies say about keys being easily copied?
We have met with them and shown our duplication studies. They confirmed that key duplication by the masses is a real issue that can change many things: did I leave the door open or was my key duplicated?
Most importantly they would adjust their rates for customers with un-duplicatable keys.

How does your solution work?
It is very simple: for centuries keys have had external security features, what we do is to place some of them inside. The Stealth key is an additively manufactured metallic key which hides most of its mechanical security features internally – rendering the key un-scannable. A patent pending key that cannot be duplicated. It is a purely mechanical solution that is very hard to copy. It uses no magnets and no electronics.

Being the Stealth key a hollow key I fear it might break when you drop it
No, it will not break. It is a metallic key with more than 99% density. Newest airplane engines from GE have similar 3D printed metallic parts inside.

How about dirt clogging the cavity, will it still work?
Yes, it still works. We have done many dirt tests and designed the key interior to be self-cleaning with operation.

How expensive is your solution?
We are proud to say that we have managed to develop a system in a similar price range as current systems but which plays in a superior league.

When will I be able to buy your security systems?
2016 will be the product launch and probably through a Kickstarter/Indiegogo campaign. We plan to arrive to certain European countries by 2016-2017.

How will I then get duplicates of your key?
At your local locksmith with a similar ID-card procedure as current systems.

Is your cylinder lock compatible with my door?
Our current products are based on the Swiss cylinder profile and also the European profile. However, we plan to adapt to more markets later on.
