Portable Door Lock for Extra Safety
Overview
The Portable Door Lock 2Pack (Rerishom / “Locker”) is a small, travel-friendly supplemental lock designed to add privacy and prevent unauthorized entry. It uses a metal insert and an internal locking piece (red & black, stainless steel + ABS plastic) to block the door from being opened from the outside even with a key. The pack is advertised for home, hotel, apartment, bedroom and travel use and retails around $14.99.
How the lock works (brief)
- Insert the metal piece into the door strike (the gap in the jamb where the latch sits).
- Close the door so the inserted metal piece is trapped in the strike.
- Fit the internal handle/locking piece (red & black component) onto the metal insert inside the room — this prevents the latch from retracting and keeps the door firmly closed.
Does it fit apartment and bedroom doors?
Short answer: Yes — for most standard inward-swinging apartment and bedroom doors. Many users report successful use on bedroom and front doors. The device is specifically made for doors that close into a strike plate and create enough space to accept the metal insert.
Compatibility checklist
- Works well on standard inward-swinging hinged doors (bedroom doors, many apartment interior doors, hotel doors).
- Fits doors with a conventional strike plate and enough gap to accept the metal insert.
- Ideal for temporary extra security in rentals, hotels, Airbnbs, and shared housing.
- Does NOT work on outward-swinging doors (the device requires the door to close into the jamb).
- Not suitable for sliding doors, double doors without a strike gap, or some very narrow jamb clearances.
Installation — quick steps
- Place the metal insert into the strike area of the door jamb from the outside (or align it according to instructions).
- Close the door so the insert is trapped.
- From inside, slide the red & black locking piece onto the metal insert until it seats firmly.
- To remove, reverse the steps.
What helps it fit better
- Standard interior/entry doors with a typical strike plate — most users find a secure fit.
- A small amount of adjustment if the frame is close to a wall (some users report needing to wiggle the red/black piece into place).
- For added permanent security to a main entrance, combine this portable lock with longer reinforced screws in the strike plate (user recommendation).
Limitations and common issues
- Only works on inward-closing doors — it cannot be used on doors that open outward.
- Doors with very tight jamb clearances or unusually shaped strike plates may be difficult to fit.
- Some users find the red & black internal piece a bit bulky and tricky to insert until you get the hang of it.
- It is a supplemental lock — not a replacement for a high-security deadbolt or reinforced frame if you need permanent, structural security against forced entry.

Buying considerations and tips
- Confirm your door is inward-swinging and has a conventional strike plate before purchasing.
- If you plan to use it on an exterior apartment entry door, consider adding a reinforced strike plate or longer screws for structural strength.
- Carry the included travel pouch so you can use the lock in hotels and rentals — many buyers cite travel as a primary use-case.
- Practice installing it at home so you can set it quickly when you arrive at a hotel or rental property.
Conclusion

It provides quick, portable privacy and added security for travel and rentals. It is not universal — it won’t work on outward-swinging, sliding, or certain non-standard doors — but for the majority of standard interior and many apartment doors, users report it fits and performs well.
