Armstrong's Key Retriever Tag helps you get your lost keys back anywhere in New Zealand. No app, no subscription, and not a single dollar changing hands.
Backed by over 45 years of locksmith experience, our Key Retriever is one of the simplest, most trusted key finder solutions Kiwis use to protect themselves against the cost and stress of a lost set of keys.
Ever felt that heart-stopping panic when you can't find your keys? That sinking feeling as you retrace your steps, checking every pocket and surface. We've all been there. A lost set of keys isn't just an inconvenience; it can mean expensive locksmith callouts, costly car key replacements, and a major disruption to your day.
At Armstrong, we believe in providing real security solutions and genuine peace of mind. That's why we offer our Key Retriever Service—also known as a free key finder tag—a simple, effective way to get your lost keys back, completely free of charge.
We've designed our Key Retriever Tag service to be incredibly simple for everyone involved. It’s a community-minded system that connects honest finders with relieved owners, with Armstrong acting as the secure go-between.
The process is straightforward:
Over the years, we noticed that many customers who got their keys back wanted to thank or reward the anonymous person who found them. Since we have no way of tracking who that kind stranger is, we created a "Pay It Forward" initiative.
When you come to collect your found keys, you'll have the option to make a small donation to a chosen charity, such as Kids with Cancer. It’s a wonderful way to turn your good fortune into a good deed for someone else. This is, of course, completely optional.
Don't wait until it's too late. The next time you're at an Armstrong store, whether it's for a new house key, a complex car key replacement, or any other service, simply ask our team to sign you up. It only takes a minute, and it could save you a world of trouble down the line.
Armstrong’s been reuniting Kiwis with their lost keys for a long time, and as an NZSA-certified locksmith, your key finder tag registration is handled securely by a team you can trust.
Visit your local Armstrong store today and walk away with more than just a key—walk away with peace of mind.
No, absolutely not. For your safety, the tag only displays a unique serial number and Armstrong's return address.
This ensures that if someone finds your keys, they can't tell where you live or which car the keys belong to. Your personal details remain confidential in our secure database and are never shared with the finder.
It is essential to keep your contact details up to date so we can reach you immediately if your keys are handed in.
Simply visit your local Armstrong store or call us on 0800 506 111 to update your profile. We recommend checking your key retriever details with us annually or whenever you change your mobile number.
Yes, our key finder service is excellent for businesses, especially those managing fleet vehicles or office keys.
You can register multiple tags under a single business account. This is a popular option for fleet managers, as it helps protect against the high cost of replacing modern electronic car keys if an employee misplaces them. It also works well alongside our commercial lock services for businesses managing multiple sets of office or fleet keys
The timeframe depends largely on how quickly the finder drops the keys into a mailbox and on New Zealand Post's delivery speed.
Generally, once the keys enter the postal system, they arrive at our head office within a few business days. We will contact you as soon as they are scanned into our system to arrange a pickup at your nearest branch.
The key finder tag is designed primarily for use within New Zealand using the NZ Post network.
If keys are lost internationally, a finder would need to pay international postage to return them to our New Zealand address, which makes recovery less guaranteed than domestic cases. However, the unique code still allows us to identify you if they are eventually returned to us.
No. A Bluetooth tracker, like an AirTag or Tile, uses an app and a short-range signal to help you find keys that are nearby. Armstrong’s Key Retriever Tag works over any distance in New Zealand using the NZ Post network rather than Bluetooth. It can bring your keys home even if they’re found on the other side of the country.
