Locks: FAQ

How do I ensure the lock fits my door thickness?

Measure your door thickness in millimeters and compare it to the seller's 'Mortise' specifications. Most AliExpress locks are designed for standard 35-50mm doors, but always verify the adjustable latch length.

How can I tell if a lock is actually made of stainless steel?

Look for '304 Stainless Steel' or 'Zinc Alloy' in the detailed description. High-quality listings often include weight specifications; heavier locks generally indicate solid metal construction rather than hollow shells.

What technical specs indicate a high-security lock?

Check for the 'C-Level' cylinder rating, which is the highest security standard for pick resistance. Also, look for an IP65 or higher rating if you are installing the lock outdoors to ensure weatherproofing.

Will the lock arrive safely without damage to the internal electronics?

Reputable sellers use custom foam-padded boxes to protect smart components during transit. Choose 'AliExpress Standard Shipping' for better handling and tracking of these sensitive hardware items.

Recommendations for buyers

✓
Cylinder Security Grade
Always prioritize locks with a C-level cylinder rating, as these are engineered to resist professional picking and drilling for at least 270 minutes.
✓
Connectivity Protocol
For smart locks, verify if the device uses Zigbee, Bluetooth, or Wi-Fi. Zigbee often requires a dedicated hub but consumes significantly less battery power.
✓
Emergency Access Features
Ensure any electronic lock includes a hidden mechanical key override and a micro-USB emergency power port to prevent lockouts if batteries fail.
✓
Material Integrity
Select hardware made from 304 stainless steel or high-density zinc alloy for superior corrosion resistance and structural strength against forced entry.
