What Is a Key Finder?

A Key finder is a device that is used for opening, locking or re-keying locks. Key finders come in different shapes and sizes and most of them use a high-powered magnet to open the lock.

The key finder can be attached to any object with a metal surface and is used in three main ways:

– Open: Attach the key finder onto a piece of metal like a car door or locker and it will open the lock with ease;

– Lock: Attach the key finder to an object that you want to lock;

– Rekey: Replace your existing keys with one attached to the key finder.

Types of Key Finder Available in the Market

There are many types of key finders available in the market. The most popular ones are:

Magnetic Key Finder: This is a key finder that has a magnet that can be used to hold onto any metallic object.

Bluetooth key finder: A Bluetooth key finder is a small device that can be carried around and used to find lost keys. With Bluetooth key finder, users can quickly locate their misplaced cell phone and get it back in their hands.

They can use it to find keys, other lost items like wallets and glasses, even pet dogs and cats if they own the device.

It has a small speaker that emits sound waves in an area of approximately 40 meters. The sound waves bounce off any objects nearby and return to the key finder. If the key finds, you will hear it making an audible beep.

RFID Key Finder: This is a key finder that uses radio frequency identification technology to identify objects with an embedded tag or chip.

How Does a Key Finder Work?

A key finder works similarly to a locator beacon for a lost dog or cat. When activated, the signal is sent out and picked up by a receiver which then sends the signal back to the device, thus giving the user an accurate location of where their item is located.

They are typically designed with one or two hooks that easily hook into the tumbler mechanism on the lock’s side plate.

A key finder is typically used by someone who has lost their keys and needs to open their lock quickly. The devices work by finding tumblers in order to unlock them without having access to the actual keys.

In order to make sure that your key finder works properly, make sure it’s fully charged before you use it for its first time.
