Everything about the KeyID
That's how one of the first reviews put it — and it's exactly what the KeyID is built for: a tag on your keyring that any finder scans with their phone camera. They write to tell you where your keys are; your address and your name stay invisible. Here's how it works, why the KeyID exists and what's inside it.

Why the KeyID exists
Handed in by an honest finder. Collected by no one.
A bunch of keys is the most anonymous thing in your pocket — and that's exactly its problem. Whoever finds it can do nothing: no name, no number, no clue. And you can't change that either, because common sense forbids an address label on your keys. So the finder carries them to the lost-property office, where they sit beside a hundred other bunches that no one ever collects.
Meanwhile you're doing the maths at home: wait it out or change the locks? Front door, letterbox, cellar — and heaven help you if one key belongs to a locking system. And all the while the solution was just one scan away: a finder who wanted to help and had no way to.
Hassle beats good intentions.
The KeyID gives your keys that way: scan, write, return — without them ever revealing where they belong.
„No one can return a key that has no way back.“
— Das SilentLink-Prinzip
The difference
The same keys, slipped from the same jacket pocket — two outcomes, depending on what's on the ring.
Without the KeyID
Days — and costly
New locks, new costs — and the uneasy feeling stays anyway.
With the KeyID
≈ 2 hrs
Your keys are back before you've even googled a locksmith.
Whether a bunch of keys comes home is decided by the way to reach you — not the lost-property office.
The technology behind it
Three stops lie between the finder and your phone — none of them needs an app, and none reveals which door your key opens.
Step 01
The ordinary phone camera opens a lean page with whatever you've saved: say "4 keys, red fob". The finder knows straight away they've got the right ones — and learns nothing more.
Step 02
Their message travels encrypted via servers in Germany and the EU to you. No name, no address, no number goes along the way — your keys stay as anonymous as keys must be.
Step 03
The message reaches you via WhatsApp, email or optionally SMS — with the find location as an address and map link. Replies travel back through SilentLink, and if it needs to be quick, the finder can call you directly — relayed through SilentLink, on the Premium plan. That's how you arrange the handover wherever suits you.
Works with any smartphone — the finder needs neither an app nor an account.
Scan ≈ 00:02 min · find location by GPS · address stays invisible
Anonymous on principle
Keys follow a special rule: the more they reveal about you, the less you can afford to lose them. That's why the classic tag with your name and address rightly stays on the stationer's shelf — and why lost-property offices are full of bunches no one can match to an owner. Until now, reachability and anonymity were mutually exclusive for keys.
The KeyID unties exactly that knot: there's nothing on the tag — no name, no address, not even a city. Whoever scans it reaches you via SilentLink, and you decide what you reveal and where you meet. Your keys become contactable without ever giving away where they belong.
Try it yourself
Point your phone camera at the code — you'll see exactly the page a finder sees after scanning: the demo bunch with four keys and a red fob, one question, one button. No download, no account.
No second device to hand? Open the demo straight in your browser. And if you'd like to use the platform yourself in the meantime: Create a free QR code to print at home — notification by email, ready in two minutes.
Privacy as architecture
Your name, address and number aren't on the tag, not in the QR code and not in the message — they can't surface along the way, because they never travel the route at all.

Understanding, not fine print
The questions we get asked most — answered the way we'd answer a friend.
The KeyID is a QR tag from SilentLink for your keyring. Whoever finds your keys scans the tag with their ordinary phone camera and writes to you — the message reaches you in seconds via WhatsApp, SMS or email, without the finder ever seeing your name or address. No battery, no app, developed in Germany.
Because a key and an address are a bad combination — everyone senses it, which is why classic address tags on keyrings rightly go unused. The KeyID solves the dilemma: the finder reaches you instantly but learns neither who you are nor which door your key opens. You decide what you tell them and where you meet.
A lean page with whatever you've saved — say "4 keys, red fob" — and a single question: what's this about? Write a quick note, send; no ads, no account, no app. You can see the page for yourself in the live demo.
Yes: when sending their message, the finder shares their location with one tap — the find location then appears as an address with a map link right in your notification.
That stays your decision — but the situation is a different one: without a way to reach you, all that's left after a loss is uncertainty, and that argues for changing them. With the KeyID the finder often gets in touch within hours, you know where your keys were and that they could never be matched to an address. It's exactly that certainty that usually makes expensive locking-system swaps unnecessary.
The KeyID hangs on your keyring and brings lost things back. The RescueID comes as a wristband or pendant and is made for emergencies: through it, helpers reach your family. Same technology, different jobs — both run on the same account.
Like every SilentLink ID, the KeyID costs a one-off €24.99. After that the Starter plan is free forever, including WhatsApp notifications; Premium (€19.99/year or €2.49/month) is optional — all the details in the plan comparison. One plan covers all your IDs, from your keyring to your car.
SilentLink — a German company from Wuppertal that builds contact points for car, luggage, pet, keys and emergencies. Designed and manufactured in Germany; all products share one account, one dashboard and one plan.
The next step
The KeyID costs a one-off €24.99, is active in two minutes and on your keyring from today. The rest is reachability.
Privacy
You know the drill: we see what you like here and which ads land — and you see less nonsense in return. Essentials run anyway. Details: privacy policy.
