Our Top Picks

Best Overall: Tile Mate - Key Finder

Tile Mate is the No. 1 best-selling Bluetooth tracker, and for good reason. The innovative company was among the first to enlist the use of Bluetooth to help people find their keys, wallets, cars and other valuables. The iconic white rectangle is now 25 pecent smaller than the original, less bulky and able to go more places. Just use your smartphone app to locate any nearby possessions and the Tile Mate will play a loud tune to help you find it. You can also use adhesives to stick your Tile Mate on your phone so you can activate the ringer and locate your valuables.

If your device is out of range, Tile Mate will track the location history, so that you have a better idea of where you last had it. But the best part about Tile is its extensive community. You can report a missing item on the Tile Mate app and if it is close by then one of five million Tile Mate customers can report its location to help you find it. Tile can last on a single charge for up to a year, so you don’t need to worry about recharging or doing any other maintenance.

Runner-Up, Best Overall: Esky Wireless RF Transmitter

The Esky remote is a clever and colorful way to keep track of your keys, cat or wallet. It is a simple RF device with four color buttons that correspond to four attachable key finders. The radio frequency has a range of 30 meters and can go through walls, doors, cushions and any other material between you and your lost possessions. When you press the button, the corresponding device will light up and beep, drawing you to your device. If it is dark outside a handy LED light attached to the remote will also help you find your way.

Loudest Key Finder: KeyRinger

If you are worried that the small square Bluetooth finders won’t be loud enough in a noisy environment, invest in the KeyRinger, the loudest key finder on the market. The set is not as discrete as the Tile and similar devices; they really are meant to be attached to your keys and not much else. They work as a pair, two KeyRingers about the size of a USB drive attach to a pair of keys, one calling the other in times of need. When you lose one device, you have a range of up to 300 feet to activate from the other. The call produces an extremely loud screeching sound that will let you know exactly where your item is in a hurry, whether it is deep under the couch or out in the lawn. The battery lasts an above-average 18 months and can easily be replaced. The product is very durable, built with a high-impact polycarbonate case that will not easily break. If it does fracture, a two-year warranty will have you up and running in no time.

Best for Families: Click ‘n Dig Model E4 Key Finder

Help everyone in your family find their keys with the Click ‘n Dig family pack, which includes four colorful RF receivers and one transmitter. There are two flat receivers and two key ring receivers, so they can serve different purposes depending on people’s needs. The flat transmitters can even be attached to laptops and other devices with double-sided adhesive. To find someone’s lost object, hit the color-coded button and radio frequency will disperse through walls and cushions to trigger a loud beeping sound and flashing light. The 80-foot range isn’t the best on this list, but it will be enough to find something anywhere in the house. The E4 model is constructed with a durable build that won’t break in pockets or backpacks and the 90 decibel siren is loud enough to draw your attention.

Best Smart Key Finder: Luxsure Anti-Lost Tag

Luxsure brings a new dimension to key finder technology with its smart anti-lost tag, an effective app will both beep to show that they have been disconnected. If you don’t immediately notice the beeping, then the app will keep track of the last position on the map, making it easy to backtrack to your lost device. The Luxsure community can also help fill you in on the location of your lost devices. The smart tracker attaches to keys, remotes, pets or other devices and is made of high quality plastic that makes the key finder more sturdy and longer lasting. A low-energy battery makes the device last for up to 10 months and replacing batteries is easy and inexpensive.

Best Value: Magicfly RF Key Finder

If you want to keep track of your keys, dogs, wallet, car, backpack and phone all at once, your best bet is the Magicfly RF remote, an incredible value that keeps tabs on six of your possessions with a central remote. The sleek black wireless finder contains six numbered tiles that are thin and can be attached to keyrings or simply stored in your item of choice. Simply press the on/off button on the receiver to locate your item, causing an 80-decibel or higher ring throughout the house. The maximum range is 100 feet of open space and you can replace the batteries on your own whenever they run out.

What to Look for in a Key Finder

Flashlight - In addition to an audible alert, some key finders include a blinking light. Some also allow you to use the light as a flashlight, which can be handy whenever you have to unlock your car or house in the dark.

Digital leash - When a key finder with this feature gets too far from your phone, it automatically sounds an alert. This can come in handy if your keys ever fall out of your pocket, or you set them down and accidentally forget to pick them back up.

Bluetooth vs. RF - Key finders that use radio frequency (RF) technology are typically cheaper and come with more key fobs. Bluetooth key finders can offer more functionality, though. Some allow you to use the key fob in reverse to find your phone, and you may even be able to use a network of other users to find your keys if you lost them somewhere outside the range of your phone’s Bluetooth.

Product keys are one of the ways software developers protect their products against piracy. Unfortunately, they're easy to lose, which can be a real problem if you need to reinstall Windows or any other software from scratch

If you've bought a desktop PC or laptop with Windows 10 already installed, you'll probably find its product key on a Certificate of Authenticity sticker on the the case or in the included paperwork, but not if you've built your own PC and installed the operating system yourself.

Many other applications also require product keys if you reinstall them – including Microsoft Office – and if you've lost the email you received when you first installed them, you could be in real trouble later on.

Product key finders only work for software that's already installed, so download one and make a note of all your keys now, so you're prepared in advance.

1. Belarc Advisor

A wealth of information about your hardware and software

Automatic updates
No security score for Windows 10

Belarc Advisor is primarily a tool for gathering information about your Windows system, including hardware, security updates and product keys.

Whenever you run Belarc Advisor, it automatically checks its database for software definitions – essential for finding keys for new programs. After that, it scans your system and presents the findings in an HTML page in your default web browser. Scroll down to 'Software licenses' to find serial numbers and product keys for Windows, Office and many other applications.

Belarc Advisor offers a wealth of other information, including details of your antivirus software, connected hardware, and other devices on the same network. It also offers a security benchmark score, though sadly this is only available for Windows 7, Windows Vista and Windows XP Pro.

Belarc Advisor's scans are fast and offer so much more information than just serial numbers, it's our favorite free product key finder.

3. LicenseCrawler

Find the keys for Windows and a wealth of other software

Portable
Occasional ads

LicenseCrawler will find the license key for pretty much any application that has one, and it's free for home use. Its scan of the Windows registry takes a long time to complete – even if you select the 'high speed' option – but you can limit its scope using the blacklist and whitelist filters.

LicenseCrawler is distributed as a portable app, meaning you don't have to install it on the Windows system you're scanning – just download the zip file, extract its contents and run LicenseCrawler.exe. This is particularly handy if you have several PCs; just download it to a USB stick and you can just plug it in and run it on any of them.

The only downside of LicenseCrawler is the occasional pop-up ad, but finding product keys isn't a task you'll be performing every day, so they're only a minor inconvenience.

4. Windows Product Key Viewer

A quick way to find your Windows product key, but nothing else

Portable app
Some misleading ads on site

Windows Product Key Viewer is super fast, taking barely a second to scan your system and present the results. That's because, as the name suggests, it only supplies the product key for your operating system.

That shouldn't necessarily put you off though. Although it doesn't find serial numbers for other applications, it does provide some extra information about your OS, including the registered user, install date and last boot time, and it's compatible with versions of the operating system from Windows 10 all the way back to Windows 95.

Take care when downloading the software – the site includes some ads that look like download buttons for the software, but are in fact unrelated. Only click the link 'Download Windows Product Key Viewer'.

5. Free PC Audit

A super simple way to find your Windows 10 product key

Portable

Free PC Audit is another portable application, and doesn't even come as a zip archive – just download the exe file and run it to begin scanning.

Like Belarc Advisor, Free PC Advisor provides a wealth of information about your whole system – not just its software – though its interface isn't quite as intuitive. It's compatible with all versions of Windows, from NT all the way through to Windows 10, but doesn't find keys for Microsoft Office or any other software.

It also provides lists of all installed software and running system processes, though this information is readily available through Windows itself.
