FAQs
Please read our FAQs page to find out more.
Can it be used on different door types?
Yes, the AceMining Portable Door Lock is designed to work on various door types with its versatile design:
Compatible Door Types:
Hotel room doors (most common use)
Apartment and dormitory doors
Bathroom and bedroom doors
Short-term rental doors (Airbnb)
Standard residential doors
Key Compatibility Features:
Two hole sizes: 0.78 inches for normal doors and 1.2 inches for doors with larger bolts
Works with inward-opening doors only (important limitation)
No tools required for installation on any compatible door
Important Note: Several customers mention it works on "every outside access door" they've tried, though it won't work on doors that open outward (like some cruise cabin doors).
Does it require any tools for installation?
No, the AceMining Portable Door Lock requires no tools whatsoever for installation.
How simple it is:
Just insert the metal piece into the slot of the door lock
Close the door
Position the pink handle groove onto the stud on the metal sheet
That's it—ready to use
It comes with everything you need in the box—just the lock, dustbag, and manual. No screwdrivers, hammers, or anything else required.
Is this lock pick proof?
The AceMining Portable Door Lock is not specifically designed to be pick-proof in the traditional sense. Here's what customers report:
What it actually does:
Prevents unlocking attempts – Reviews suggest it deters someone from unlocking the door from the outside
Adds physical resistance – One traveler tested it and said "Good luck opening that door once the key is engaged...I really tried to pull that sucker open, and so did my friend"
Creates a noise barrier – If someone tries to force entry, it will make noise, giving you time to react or call for help
Important limitations:
Not designed for forceful kicks – Customers note it may not withstand a violent kick or physical force
Best for deterrence – Its main purpose is preventing unauthorized entry through normal door handling, not resisting brute force
Bottom line: This lock is designed for hotel and travel security to deter opportunistic entry or picking attempts, not as a high-security lock against determined physical force. It's ideal for peace of mind during solo travel, but shouldn't be your only safety measure in unsafe situations.
Is it easy to carry?
Yes, the AceMining Portable Door Lock is designed for portability. It is small in size and can be easily carried when travelling.
