The main objective of keyless mobile controlled locks system is to unlock a garage door (different type’s door) by a mobile phone using a unique password entered through the keypad of the phone. Opening and closing of garage doors involves human labor. In this password system, the opening and closing of a garage door is achieved by using a mobile phone. The owner can call to a mobile phone interfaced to the system which in turn is connected to the garage door that can open/close the door by entering the password.

The owner can call to a mobile phone interfaced to the system which in turn is connected to the garage door that can open/close the door by entering the password.

This kit is based on the concept of DTMF (dual tone multi frequency) technology. Every numeric button on the keypad of a mobile phone generates a unique frequency when pressed. These frequencies are decoded by the DTMF decoder IC at the receiving end which is fed to the microcontroller. If this decoded values (password entered by the user) matches with the password stored in the microcontroller, then the microcontroller initiates a mechanism to open the door through a motor driver (L293D IC) interface.

The objective of this kit is to develop a device that allows for a user to remotely control and monitor a garage door using a cellular phone. This system will be powerful and that will provide this service at any time, and from anywhere.
