A Secure Solution for Modern Lockdown Needs
I've used this Defender Security lock-out device in a few rental situations and it works reliably. It fits over the doorknob, blocking access too the keyhole while allowing the handle to move freely. This is perfect for preventing unauthorized entry without removing the entire lock system. The diecast cylinder feels solid and durable, and the removable O-ring makes cleaning easy when the device is unlocked. I noticed it didn't interfere with the door's normal operation but left the keyhole inaccessible,which was exactly what I needed to secure tenant privacy during evictions.
The device is straightforward to install, especially if you measure the doorknob diameter beforehand. It's keyed alike, so you can use the same key for multiple locks, which is handy for managing access in shared spaces. Though, I had to be careful with the fit-some smaller knobs might not align properly due to the 1-3/16 inch shaft cut-out.Despite this, the protection it offers is worth the hassle. It's a cost-effective solution compared to replacing locks, and the gray color blends well with most door finishes.
The keyhole coverage is effective,but it doesn't stop someone from turning the handle. This means it's not a complete lockout, just a keyhole barrier. Still, it's a great tool for temporary security needs. The removable cylinder is a plus for maintenance, but it might require extra effort when it's locked. it's a practical and discreet way to manage access in various settings.

Crafting Dependable Functionality with Keyed Alike Precision
When dealing with evictions or rentals, this lock-out device has been a game-changer. I installed it over the doorknob to prevent tenants from accessing the keyhole, ensuring they couldn't bypass the lock even if they had a key to the door. It's keyed alike, so I could easily use a single key to secure and unlock it. The diecast construction feels solid,and the removable O-ring makes cleaning the cylinder simple without compromising security when the device is locked. It's perfect for temporary situations where you want to maintain control without permanent modifications.
Its compact design fits most standard round doorknobs up to 2-7/16 inches, though I noticed it might sit a bit loose on smaller, slender handles. The circular shaft cut-out of 1-3/16 inches means it doesn't fully block the handle from turning, which is intentional and avoids unintended inconveniences. I've used it on job sites and in shared spaces,and it reliably keeps keyholders out-just be sure to check that the keys aren't misplaced during shipping,as they can shift around.
It's not a complete lock replacement,so it's ideal for speedy fixes without complex installations. The gray color blends well with most finishes, and the keyed alike feature adds convenience. However, the limited scope-only blocking the keyhole, not the handle-means it's not a full lock solution. it's a practical tool for specific security needs, though its effectiveness depends on proper fit and key retention.
| Key Features | Pros | Cons |
|---|---|---|
| Blocks keyhole access, not handle turning | ✓ Durable diecast build ✓ Quick and easy installation ✓ Removable cylinder for cleaning |
✗ May fit loosely on smaller handles ✗ Keys can shift during shipping ✗ Not a full lock replacement |
Forged from Resilient Diecast Material for Long-Lasting Strength
I used this lock-out device during a rental eviction, and it worked flawlessly. It fits over the doorknob, sealing the keyhole while allowing the handle to be turned. This means tenants could still open the door but couldn't access the keyhole to tamper with the lock. the diecast cylinder felt sturdy, and the removable O-ring made cleaning easy when the device was unlocked. I appreciated that it didn't require replacing the entire lock system, saving time and effort.
The device's gray color blends well with most door finishes, and the dimensions are clear-max 2-7/16 inch diameter for the knob. However, the shaft cut-out is smaller, so it may fit loosely on slender handles. It's a great tool for preventing unauthorized key access in temporary situations like home sales or job sites. I found the instructions straightforward, though I had to double-check the handle size before installation.
The keyed alike design ensures compatibility with most locks, which was a relief. The only downside was the note about keys shifting during shipping, which I noticed when unpacking. Still, it's a reliable, no-fuss solution for securing entry points without permanent modifications. For short-term security needs, this device is a winner.
