In general, a smart door alarm and locking mechanism and methods for use thereof are provided for maintaining security while providing ease of access to a fuel dispenser. In an exemplary embodiment, the methods and devices are used in fuel dispensing devices for providing fuel to a vehicle. However, the methods and devices can be utilized in any device having a payment system where security and access are both required. In some embodiments, the described methods and systems include a door alarm and door lock kit that allow unlocking one or more doors in a housing of a fuel dispenser and simultaneously disabling or de-activating respective door alarm sensor(s). In a similar manner, the door can be locked and the door alarm sensor activated or re-activated substantially simultaneously.

A system for warning that a fuel line nozzle should be removed from a gas tank, by: determining that a fuel pump nozzle has been tilted from its resting position in a pump cradle to a refueling position where it has been inserted into a gas tank tube; and then determining that fueling through the fuel line has stopped by detecting vibration of the fuel pump nozzle when the fuel line shuts off; and then activating an alert system including a warning light and an audible sound if the fuel pump nozzle has not been removed from the gas tank tube and returned to the pump cradle after a predetermined period of time. The system can also wirelessly transmit fuel line use data to a remote computer.
