I am using a swift dezire car by the last six years which with a remote locking system of nippon. One of my remote got complaint by means o[censored]sage and contacted the maruti dealer for service (Indus motors trichur).

Afterthe discussion he informed me that the expense will be rs:1000/ for the new sensing unit and he directed me to the authorised service centre of nippon at trichur. I visited them with my car at their office and they given me the service required but they demanded rs-1300/-. I have to pay the bill because there was no other way.
I dont know the actual value of the sensing unit without shell. From some relaible sorces i happened to know that the price will be rs850/- at the maximum. Would you please inform the real senario
