For those who enjoy watching TV or driving a car, spending time looking for a lost remote controller may be an unpleasant experience. In order to solve the problem of finding a lost remote controller, a searcher adopted to generate a buzzer sound has been commercialized. The navigator structurally includes two parts, one of which is a small part of the positioning alarm to attach to a lost item such as a remote controller, a watch, a key, a Braille stylus, a wallet, etc. One is the main body of the searcher provided with a push button. When the push button on the main unit is pressed, a positioning alarm attached to the article will sound. The user will follow the sound to locate the lost item.

The explorer is easy to use, but it adds to the effort of buying and carrying it.

On the other hand, a remote controller equipped with a signal transmission and reception function and a warning function has been widely used. However, such functions are not well made and are not fully utilized. For example, a two-way car antitheft unit is very common, but its two-way remote controller is not capable of sending signals to remotely control the car for theft protection purposes, and when the antitheft unit is activated. Nor can the warning signal be received. Once the activation warning signal is received, the remote controller generates an alarm sound or vibration or displays an image to alert the user. The car remote controller may be used to remotely control one, two or multiple cars at the same time. However, currently available automotive anti-theft remote control units are generally only used to remotely enable and disable the anti-theft unit or can only receive activation warning signals to search for or search for a person or article. It is not used as an apparatus.

It is a first object of the present invention to provide a two-way remote control unit comprising a two-way remote controller having a calling and positioning function. Therefore, there is no need to spend additional costs to purchase a calling device or a searcher, and no need to carry a caller or a searcher around.
