An alarm device for preventing theft of a vehicle having a kickstand support attached to the vehicle having: a housing associated with the kickstand support; a pressure sensing component located associated with the housing and adjacent an end of the kickstand for detecting a force of the kickstand on a ground surface, the pressure sensing component including a surface area for contacting the ground surface when the kickstand is in the deployed position; a controller in electronic communication with the pressure sensor for determining whether the kickstand is in contact with the ground surface based on measurements from the pressure sensing component; a communications module in electronic communication with the controller for wirelessly communicating with a user device. The controller generates an alarm when the kickstand is in the deployed position and determines that the force of the kickstand on the ground has changed by a threshold amount.
