If you are reading this article, you are probably the type of person who often has to go through the whole house to find their purse, keys or wallet. That stressful moment where you just don't have the time to look through all your house for your car keys. Then, a keychain tracker is definitely made for you.

Discover in this article how this type of small GPS tracker works, the technology behind it, but also in which use cases it will be most useful to you. All you need to know to choose the best GPS tracker depending on your needs.


The purpose of Bluetooth trackers

Two Tile Mate keychains

Tracking tags or Bluetooth trackers don't have a SIM card nor a GPS chip like conventional GPS trackers. Thanks to Bluetooth technology, they require less energy and are as small as an ordinary keychain. However, there are some limitations, as explained below.

Locating your keychain tracker

How it works is quite simple: the keychain tracker or Bluetooth tracker has a built-in Bluetooth chip enabling a maximum signal range of 164 ft. (50 meters) between the transmitter (the tracker) and the receiver (your phone). The GPS tracker sends this signal directly to your phone and you can locate it within close range.

The main drawback is the maximum range of 164 ft. (50 meters), especially since it's only effective in ideal conditions, which means: a clear environment, without obstacles (such as a wall). Today, most recent Bluetooth trackers can sometimes go up to 262 ft. (80 meters) in range (in the best conditions).

The Crowd GPS concept

How it works

As mentioned above, the biggest drawback of this type of tracker is its maximum range of 164 ft. The Crowd GPS concept was introduced to overcome this drawback. This concept called Crowd GPS relies on everyone who has the same Bluetooth GPS receiver. Each person passing near the Bluetooth tracker will update the GPS position of your tracker thanks to the Bluetooth and the GPS of their own smartphone.

Of course, the problem is the size of the community. In a big city like Paris, this type of tracker will be much more likely to work than in a village of 300 inhabitants. There are many requirements for this type of Bluetooth tracker to be truly efficient. It's actually more of a gimmick than a real tracking and monitoring device.

Apple’s Airtag

Apple's Airtag uses the large community of iPhones owners around the world. These tracking tags work by relying on the Bluetooth of the iPhones in our cities. Therefore, the Airtag is perfect to find keys, wallets or handbags.

However, for any other use (finding your dog or cat, tracking a car or a bike) it is better to use the appropriate products. We recommend choosing the right trackers for the right use. Here are some examples of brands for each use: Invoxia for cars, motorcycles and bikes, Apple or Tile for your keys, or Weenect for your pets, Garmin to find an animal in a dense forest with trackers working on radio frequency.

Pros and cons of a Bluetooth tracker

Bluetooth trackers for different objects

Pros of Bluetooth trackers

The main advantage of Bluetooth trackers is that they provide a very accurate location within short range. This is especially true with the "hot and cold" system of the Airtag for example. This highly accurate geolocation will help you easily find your car keys, or your key ring in your apartment with over 95% reliability.

We think it is the perfect Father's Day gift. Colorful, customizable, with faux leather accessories, you can match it with everything, it can even be used as a bag charm. All these options go hand in hand with its very attractive price. This custom keychain is one of the most popular smart objects in recent years.

Cons of Bluetooth trackers

These tracking tags have some major drawbacks. First, this type of system is based on the community around the tracker. So it works very well in large crowds but what happens in more rural areas? Will such trackers really be efficient there?

Besides, crowd GPS technology only works if both the Bluetooth and the GPS of the person passing by your object are switched on, but more and more people switch them off to save battery life. So there is a good chance that someone may pass by your tracker without it updating its position.

Above all, it is the over-reliance of this type of tracker that makes it a gimmicky solution at best. A keychain tracker only has a GPS position on a third-party device (usually a phone), it never knows its own position. It is not independent, which is a major limitation for any truly security-related uses.

A list of keychain trackers

Tile Mate

At under $24,99, the Tile Mate keychain track has a 12-month battery life, it's water resistant and can play a ringtone to make it easier to find. The maximum Bluetooth range is 45 meters in an open environment.

Nutale, the object tracker

More stylish than its competitors, it will cost you about $24,99. Each tracker has a 10-month battery life. You can buy it by pack of 4 so you can attach it or fix it on different objects. The app helps you locate each object easily.

Apple Airtag

Apple's famous Airtag will cost you $29 both in stores and online. You can use both the app or SIRI voice assistant to find your lost objects in seconds. Its greatest asset is the large iPhone community that better maps the territory and makes it easier to locate trackers. The Airtag has a one-year battery life. Its oval shape is elegant and exclusive. It can be customized with a free engraving on purchase.

However, expect to pay an additional $35 to Apple for a leather keychain, case or other. This is an essential accessory, as the Airtag alone cannot be hung anywhere, it can only be slipped into a bag. Locating objects will be a breeze for iPhone users with Airtags. But it has a very limited range of about 32 ft. indoors.

When should I use a Bluetooth tracker?

Two types of object trackers

To find everyday objects

To find your keys, or your wallet, a Bluetooth tracker like an Airtag or a Tile tracker will be perfect for the job. Apple's Airtag, Tile's Tile Mate or Samsung's Smart Tags are great as tracking tags. Very convenient to carry around with you hanging on your keys or slipped into your handbag.

All these products have a built-in ringtone that will help you find your phone that has fallen behind your sofa. Bluetooth provides location within a limited range, as it requires the support of a community to allow location over 164 ft. (50 meters) away. This technology is perfect for everyday objects but not for tracking a bike or a living being for example. In such cases, you will need to buy another type of GPS tracker.

To find a lost pet

Be careful, it is not recommended to attach a keychain tracker to your pet's collar. Indeed, Bluetooth trackers are completely useless to find a lost pet. A lost dog or cat is often panicked, scared and will move around quickly. A GPS Bluetooth tracker for dogs or cats must be able to locate them in real time and more importantly without any range limit (which Bluetooth trackers do not provide).

A Bluetooth tracker is more of a gimmick than a security device. It requires too many conditions to properly work, making it useless to find a lost pet.


Bluetooth GPS trackers or keychain trackers are more of a gimmick than a safe tracking device. Indeed, too many conditions must be met for it to work properly. On the other hand, it allows you to find everyday objects and avoid wasting time looking for your keys or your phone before leaving your home. This type of tracker can make your life much easier and avoid unnecessary frustrations thanks to accurate GPS location.
