A basic key-cutting and lock-repair setup (vice, files, a stock of common key blanks, basic hand tools) is low-cost and has traditionally been run from a simple table or stall, as documented in a long-running real-world example from Bangalore. Under PM Vishwakarma, eligible locksmiths can access a Rs 15,000 toolkit incentive via e-RUPI voucher plus loans of up to Rs 1 lakh (18-month repayment) then Rs 2 lakh (30-month repayment) at 5% concessional interest.
No independently verified earnings figure for locksmiths/key makers in India was found, so avoid trusting specific income numbers online - a real-world profile (Citizen Matters) of a long-running Bangalore locksmith describes decades of sustained local business built purely on reputation, without disclosing specific earnings.
