Yes, TRV plays a major role also it determines the locker size in most of the private banks. My issue is my Home Branch doesn't have the facility and the branch(referred) nearest to me has a limited locker and is already occupied as it covers a lot of area. I also have good TRV in ICICI. So, I am waiting for IDFC to start the service, also it is a new branch no rush for the locker as of now.
