How to Duplicate a Key in Amsterdam Without the Original
Duplicating a key in Amsterdam without the original is the process of producing a working key from the lock cylinder itself, using either a code reading on the lock or, when needed, opening and re-pinning the cylinder by a certified locksmith.
It is one of the most common questions we get: ‘I lost the only key, can you still make a copy?’ The short answer is yes, almost always. With 24-7 Locksmith Amsterdam we work directly from your lock, on-site within 30 minutes, with a fixed price agreed before any work starts.
Method 1: cutting a key from the lock cylinder
If your lock is in good condition, our technician can read the cylinder and cut a fresh key based on its internal pattern. This is called impressioning or decoding, and it does not damage the lock.
You keep the same cylinder, the same door hardware, and a working key in your hand. The whole process usually takes less than an hour, and we test the new key in your door before we leave.
Method 2: replacing the cylinder when you cannot risk a copy
If you have lost the only key and you do not know where it is, copying the existing cylinder may not be the safest option. Whoever picks up that key still has access to your home.
In that case we recommend swapping the cylinder for a new SKG-certified lock and giving you a fresh set of keys. Your insurance stays valid, your old key becomes useless, and the door hardware itself stays the same. We handle this on-site across Amsterdam, from Centrum to Amsterdam-Noord.
When a code is enough
Some Amsterdam apartments come with a security code card from the lock manufacturer. If you have that card, even without the physical key, an authorised locksmith can order a precise duplicate from the manufacturer.
This is the cleanest way to replace a lost key without changing the lock. If you are not sure whether your apartment came with a code card, check the documents your landlord or property manager handed over.
What to do before we arrive
Two small steps make the visit faster. First, find any paperwork that came with the lock. A code card, a manufacturer brochure, even a sticker inside the door frame can give the model number. With that, we can sometimes order a precise replacement key from the manufacturer rather than decoding the cylinder.
Second, do not try to force the door or pick the lock yourself. Even small damage to the cylinder makes decoding harder and can push the job from a clean copy into a full replacement. Leave the lock alone, take a clear photo of the keyhole if you can, and we handle the rest when we arrive.
Frequently Asked Questions
Can you really make a key without the original?
Yes, in most cases. We either decode the cylinder on-site or use the manufacturer’s code card if you have one.
Is it better to copy or to replace the lock?
If the lost key may be in unknown hands, replacement is safer. If the key is simply missing in a known place, a copy from the cylinder is usually fine.
Will the new key work the same as the old one?
Yes. We test the cut key in your lock before leaving so you know it operates smoothly.
Do you serve all parts of Amsterdam?
Yes. From Centrum, Jordaan and De Pijp to Oud-West, IJburg and Amsterdam-Noord, plus Amstelveen, Diemen, Weesp and Zaandam.

We are typically on-site within 30 minutes and finish most jobs within the hour.
