II. Exposing the Low-Cost Lock Picking Scam
Online listings advertising "key unlocking for 30 yuan" are often bait-and-switch traps. Once on-site, technicians may claim the lock cylinder is damaged or that a full lock replacement is needed, then demand hundreds or even thousands of extra yuan. Legitimate locksmiths registered with public security authorities will confirm the lock type and provide a clear price range over the phone beforehand, and will not add charges upon arrival.
III. How to Identify a Legitimate Locksmith
- Verify Public Security Filing Number (Tianjin Municipal Public Security Bureau Special Industry Management)
- Please provide your business license and ID card.
- Confirm that the quote includes service call fee, labor cost, and material cost.
- Request an official receipt or e-invoice
- Prioritize local service providers with physical storefronts
