Who is the Ultraloq Door Reinforcement Kit For?
This kit is designed for anyone who wants to increase the physical security of their door without a complex installation. It is particularly well-suited for renters who cannot modify the door frame permanently. The kit works by replacing the standard strike plate screws with longer, hardened screws that reach deep into the door frame's stud. It also includes a reinforced strike plate that is larger and stronger than the one that comes with most locksets.
Owner reviews on major retail sites consistently praise the ease of installation. Most users report completing the job in under 10 minutes with just a screwdriver. The kit is compatible with standard 2 3/8-inch or 2 3/4-inch backsets, which covers the vast majority of residential doors in the US and UK.
Performance and Build Quality
The core of the kit is the 12-gauge steel strike plate and the 4-inch hardened steel screws. The longer screws are the primary defense against kick-in attacks. A standard strike plate is secured with 3/4-inch screws that only go into the door jamb, which is often weak. The Ultraloq's screws anchor into the wall stud behind the jamb, dramatically increasing resistance. Aggregated owner feedback indicates a significant increase in perceived door solidity after installation.
The build quality of the steel components is good for the price point. The finish is a standard satin nickel that matches most modern door hardware. Some users have noted that the included screws can be slightly difficult to start in harder wood, but pre-drilling a pilot hole solves this. The kit does not include a new deadbolt or handle; it is strictly a reinforcement for your existing lock.
What to Check Before Buying
- Backset measurement: Measure from the edge of the door to the center of the deadbolt hole. Ensure it is 2 3/8" or 2 3/4".
- Door jamb condition: The kit is most effective on a solid wood jamb. If your jamb is rotted or damaged, the kit will not fix the underlying issue.
- Stud location: The 4-inch screws need to hit the wall stud. If your door is installed with a gap between the jamb and the stud, the screws may not reach.
Mistakes to Avoid
- Over-tightening: Do not strip the screws. Tighten until snug, then stop.
- Ignoring the latch: The kit only reinforces the strike plate. Ensure your deadbolt and latch are also in good working order.
- Expecting a miracle: This kit is a significant upgrade, but it will not make a hollow-core door or a weak frame impenetrable.
Alternatives to Consider
For a more comprehensive solution, consider a full door security bar like the Master Lock Door Security Bar, which provides a physical brace against the door. For a permanent upgrade, a reinforced door frame kit from a brand like Yale or Stanley involves replacing the entire jamb. The Ultraloq kit sits in the middle: it is more effective than a standard strike plate but less invasive than a full frame replacement.
If you are looking for a smart lock to pair with this reinforcement, the Ultraloq U-Bolt Pro is a direct match. Other brands like August and Ring also offer smart locks that will work with the reinforced strike plate, as the kit is lock-agnostic.

Our verdict
The Ultraloq Door Reinforcement Kit is the best overall choice for a quick, effective, and non-permanent door security upgrade.
