After unlocking, if items go missing, don't panic. The key factor to determine is:
Secure the scene immediately and verify the locksmith's registration details and surveillance footage—this is critical for recovering losses. Before 2026 in 10, registered locksmith companies carried service insurance, allowing you to claim compensation for the locksmith's liability; a police case receipt is also essential for subsequent civil claims. If your home has property insurance, reporting within 24 hours provides an additional layer of protection.

01 On-site Response: Three Steps to Secure the Evidence Chain
After unlocking the door and discovering missing items, never rummage through drawers or cabinets. Police need to see the original arrangement to distinguish between pre-existing belongings and items disturbed during the break-in. Your first step is to preserve the scene exactly as it is—do not touch anything, even if you're urgently searching for a lost necklace.
Step 2: Verify the unlock record. Ask the technician to show their filing certificate and ID, then record their name, employee ID, and company. Immediately pull up hallway and elevator surveillance footage to confirm whether anyone entered or exited during the unlock. These details serve as direct evidence for determining liability. Step 3: Notify property management simultaneously. Request that they provide an on-duty log confirming the lock was intact before the unlock, ruling out prior unauthorized access.
Leave everything in place — do not move any items; preserve the original arrangement. Verify lock-picking records — require proof of filing, identity information, and employee ID; retrieve surveillance footage. Notify property management — provide shift logs to confirm the door's condition prior to unlocking.
⚠️ Lock Picking Precautions
Before unlocking, confirm the locksmith is registered with the local police. Registered companies typically offer service insurance. Stay nearby throughout the process and do not leave unattended. Immediately after unlocking, inspect the lock for signs of tampering and keep the keys and lock cylinder.
02 Liability Allocation and Recovery Paths: Three Legs to Recover Losses
Determining liability after an item goes missing is critical. If surveillance footage or other evidence proves the item was taken by someone during the lock-opening process, you can claim compensation from the locksmith company. Legitimate, registered businesses typically carry service insurance, which serves as your backing for claims. Regarding police involvement, action depends on whether the amount meets local criminal filing thresholds. If it does, they will issue a case acceptance receipt; if not, they must still provide an incident report record to serve as evidence for subsequent civil claims.
If you have home insurance, report the claim within 24 hours. Keep photos of the scene, the police report receipt, and a list of damages—all three are required. Data shows that insured households receive claims at a rate approximately 60% higher in similar situations, provided the claim is reported promptly and all evidence is complete.

03 Post-Incident Prevention: Replace the lock cylinder and preserve evidence—both are essential.
Regardless of whether your item is recovered, we recommend replacing the lock cylinder with a Grade C one immediately after unlocking. During the unlocking process, keys may be duplicated. Since Grade C cylinders offer the highest level of security, they effectively prevent future break-ins. In terms of cost, a standard Grade C cylinder typically ranges from 50 to 200 yuan, while smart locks vary by features. However, the replacement cost is far lower than the value of lost items.
Maintain a complete chain of evidence: store police receipts, locksmith work orders, surveillance screenshots, and loss lists together. If negotiations fail, you may file a lawsuit or request mediation. When dealing with the locksmith company, first request their registration details and insurance policy number before discussing compensation to avoid delays from verbal promises.
💡 Editor's Tip: Replace the lock cylinder with a Grade C one immediately after unlocking. Photograph your registration details and police receipt, then store them in the cloud to create a traceable evidence chain. Do not rely on verbal promises; always refer to written documents.

05 FAQs
How long after unlocking is the alarm still valid?
Call the police immediately, ideally within 1 hours of discovering the loss. The sooner you report it, the better your chances of obtaining surveillance footage and securing evidence. Delaying reduces success rates.
What should I do if a locksmith refuses to show their registration information?
Immediately reject the transaction. Call 110 or your local police registration verification hotline to confirm. Legitimate locksmiths must have a government-issued license; anyone who refuses to show it is likely an unlicensed operator posing a high security risk. Replacing the lock cylinder is mandatory.
Can I still claim compensation without surveillance footage or evidence?
Possible, but difficult. In civil litigation, judges may consider indirect evidence such as property management logs or witness testimony from friends and family when making a determination. Therefore, it is best to record the entire process before unlocking the door, as this provides the strongest evidence.
