Normally available locks in the two wheeled vehicle do not provide any security to vehicle owner, traditional locking system used keys to lock or unlock the vehicle and these locks are well known to thieves and they can be easily broken by them, if a person having the keys of locking system then that person have the authority to lock or unlock the vehicle, the locking system doesnít know about the person is authorised or not. If the keys are lost or stolen then the owner will unable to unlock the system. About 8.1% of accident caused by teenagers (the person donít having appropriate license) and 6.4% of the accident is happens by drunk and drive cases. Statistics says that only 20% of stolen vehicles can be recovered in India.
Thus, there is a need for more security options to be available for the two wheeled vehicle which is unique and must be different from the traditional key locks. The aim of this paper to develop a biometrics system which can be used as a good and effective security option along with alcohol detector and GPS system. An important and very reliable human identification method is fingerprint identification. As fingerprint of every person is unique thus it can be used in various security options. In this study a review on various locking system in the two & four wheeled vehicles is presented. The till date work in this direction is analysed and further possible development may be analysed.
