Hero Motocorp — extreme bike key recognition problem

Address:

Bongaigaon, Assam, 783380

The keys are some times not detected for longer periods. This happens anytime, even after running for several minutes, if i switch off the key and then try to restart, the keys are not detected and bike does not start. It is very annoying and i m facing much trouble with this bike. I visited service center but no positive results. Kindly help in solving this problem
