[Resolved]  Bajaj Discover 125 Dtsi — Spare Key

I purchased a discover125 DTSi in 2006 ( RC owner M.Govinda Raj (Father) KL-11-X-8842) From KVR Motors Calicut, through Bajaj finance Calicut. After completion of loan BAFL returned the spare key to us but that key is not my vehicle's key . I informed this to BAFL but they telling that mistake is happened from KVR motors, Kvr motors telling viseversa.
How can i get original spare key?
I didn't get the balance cheque leaves at yet
