What is a key finder exactly?

Also called key locators or electronic finders, this small gadget connects to your cell phone via Bluetooth and often integrates a smart GPS function to search for any item. Some models require you to download a mobile application for the device to work its magic. This device is wearable like smartwatches or fitness trackers.

What are the advantages of key finders?

For many people, new technologies are all about making our daily life a little easier. We often welcome their advances when they can improve our daily routine. That being said, technology also has its naysayers due to the lack of privacy. In any case, the reality is that key finders offer many perks that we have listed for you below:

  • They are affordable. They can cost as low as $15.
  • Different technologies are available. You can choose a model that connects using Bluetooth or radiofrequency.
  • You will never lose your keys again. They are designed explicitly for forgetful, absent-minded, or older people.
  • Key finders can locate other objects. You can use them to find your glasses, purse, or any other item like your pet’s collar. You can even locate your cell phone when it is in silent mode, which is a great advantage.
  • They are compact. These devices are generally small and ideal for carrying as a key ring with all your other keys.
  • They offer various warning systems. Your key finder can tell you where your keys are using a sound, but also LED lights if you prefer.
  • They are the perfect gift. If your mother is always forgetting her keys, or if your child lets your dog run away every time they go for a walk, you will find key finders to be useful presents.

“Any sufficiently advanced technology is indistinguishable from magic.”

What types of key finders are there?

While you may not be aware of the latest technological devices, the market is inexorably moving towards the newest gadgets available. The younger generations naturally handle these devices with more ease, but they are accessible to everyone. In the following list, we will explain the most common types of key finders on the market based on the technology they integrate:

  • Bluetooth key finders. They use Bluetooth technology to detect nearby items using a GPS-enabled phone. These models are designed to find objects in your home. The Bluetooth version should be 4.0 or higher. They are generally available on iOS and Android.
  • GPS key finders. These devices use a mobile application to geolocate the object you have lost. They connect to cell phone towers. You can usually configure various useful functions from the app, such as the volume of the warning sounds.
  • RFID key finders. These models operate via radio frequency (Radio Frequency IDentification) by broadcasting the identity of an object through radio waves. Certain RFID key finders also incorporate LED lights for greater visibility and identification.
  • Key finders with Wi-Fi. These devices only use wireless access points to tell you where your keys are. This is particularly useful in places with low to no GPS coverage, such as a basement.
  • Key finders with LED lights. This functionality will allow you to visualize more easily your lost item. It is generally integrated into other Bluetooth, GPS, or RFID key finders.

How do community-based key finders work?

Not all electronic devices for detecting lost objects have community-based beepers, but some do. This is the case for Tile products, which have a network of users on the Internet. All you have to do is send an anonymous message about the item, and the users will help you find it without compromising the privacy of your data.

Buyer’s Guide

Now that you know just how useful a key finder can be, don’t neglect the last section of our guide. It will tell you all about the most important purchasing criteria to evaluate before choosing a model. Picking a key finder with a 10-foot range won’t be any good if you spend most of your time outside. This is why we have detailed the following aspects:

Ease of Use

Always remember why you want to buy a key finder. If it is intended for an older adult, you should prefer the most basic models. Its ease of use will ultimately determine whether you make the most of the device or if it ends up stuffed in a drawer and forgotten. If you are fond of new technologies, on the other hand, we encourage you to choose the most advanced models.

This is naturally one of the most fundamental criteria of a key finder. You won’t need a vast reach if you generally lose your keys in your apartment, but it is a whole other story if you live on a farm. As a rule of thumb, you should choose a key finder with a range of at least 60 feet for indoor use, and between 100 to 150 feet when outside.

If you feel very comfortable with the latest technological advances in this type of device, you could opt for a model that integrates an alarm perimeter functionality. That way, you are immediately warned via an alarm whenever your keys, pet, or any other item linked to the device leaves the set perimeter.


If you want your key finder to use smart object detection, buy a model with at least Bluetooth 4.0. This is the minimum version with which the technology can work, and you should opt for Bluetooth 4.1 if you can. As you know, these kinds of gadgets develop at an incredible rate; newer versions are available on the market every few months.

If you have read our product selection above, you won’t be surprised that there is such a wide range of products to choose from. That means you can also opt for radiofrequency or GPS models if you prefer. Either way, all of these technologies have proved to serve their purpose, with the former being particularly simple to use for beginners.

“I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success.”


Always go for a lithium battery model if you want your device to last. This will guarantee you at least one year of continuous use. As you can see in our product selection, the market offers a wide array of options. You can also choose AAA batteries if you find them more comfortable, or button cells.

Size & Weight

While neither of these criteria actually affect the operating of your key finder, they do influence how comfortable its use is. If you often lose your keys, you will undoubtedly want your new device to be small enough to take along without bothering you. Choosing a model that is too heavy may result in you leaving it aside after little time.

Manufacturing Material

This factor will determine the durability of the device, so don’t overlook it. We encourage you to opt for ABS plastic, a common material for key finders, as you can see from our selection of the best products on the market. One of its greatest perks is that it is truly affordable while being particularly resistant.

Additional Features

The extra functionalities and features that your key finder offers could just be the decisive factor in your purchase. People with poor eyesight or often in dark environments will appreciate a model that integrates LED lights. The advantage of this feature is that you won’t need your cell phone to localize your keys or the item you are looking for.


You may be a very organized person, but it is extremely common for us to forget things. Keys just happen to be one of the items we most often lose. Once you have your own key finder, all of these worries will go away. You will be able to find them in no time thanks to this device that uses the latest technology to improve your day-to-day life.

Before you jump in and purchase the first gadget you find online, don’t forget to evaluate the relevant criteria we have detailed above. These include the size, range, and integrated technology of the device, as well as how you plan on using it. If you are very familiar with the latest technological trends, you won’t want to opt for the same key finder as older adults who may prefer simplicity over multifunctionality.
