FAQ

To ensure your property security, the technician will request 1 upon arrival: 1. Original ID card; 2. Property deed or rental agreement (to prove you are the owner or tenant). For car lockouts, please provide the vehicle registration and driver's license. If documents are unavailable, a witness from property management or a neighbor can verify your identity.

We cover all 16 districts and counties in Tianjin using a nearest-neighbor dispatch model. Under normal conditions, technicians can arrive on-site as quickly as 8 minutes, with typical arrival within 8-20 minutes. Actual timing depends on your location and traffic; we recommend calling to confirm the nearest technician's location.

We use professional non-destructive lock-picking techniques, successfully opening locks without damage in over 95% of cases. However, for old, rusted, or severely malfunctioning locks, forced entry may be necessary to ensure safety. If you need a lock replacement, we offer a variety of new locks at different price points to choose from.

We believe in transparent pricing with phone quotes provided before arrival—no hidden fees. Starting rates: home lockout service from 80, car lockout from 100, and cylinder replacement from 120. Final prices are determined on-site based on lock type and complexity, with slight surcharges for nighttime or remote locations. The total cost will be clearly communicated to you over the phone upfront.
