Alarm Padlock - Anti-Theft Heavy Duty Security Alarm Lock - 120db Alarm Sound - Weather Proof for Door Storehouse Truck with 4 Keys (10mm) Bronze

What It Is

This is a heavy-duty, weatherproof padlock with a built-in 120dB alarm, designed to deter theft of lawn mowers, trailers, sheds, storage units, and other outdoor equipment. It’s a security accessory, not a mower repair part.

Fitment & Compatibility

• Check shackle diameter & length: The shackle is 10mm (0.39″) thick and 1.5″ (38mm) long. Measure your hasp or latch hole to ensure it fits. Too small for thick locking bars or large trailer couplers.
• Weather rating: IP66 rated – fully dust-tight and protected against heavy rain. Suitable for outdoor use on mower decks, shed doors, or truck toolboxes.
• Key count: Comes with 4 keys. No keyless entry option.
• Battery: Uses a built-in, non-replaceable battery (claimed 1-year standby). Once dead, the lock is disposable.
• Alarm trigger: Motion/vibration sensor – locks automatically after 30 seconds of closing. No manual arming.

Key Things to Know

• Loud but short alarm: 120dB blast lasts ~30 seconds, then auto-resets. Not a continuous siren – can be annoying if accidentally bumped.
• No remote or smartphone integration: You can’t disarm it remotely. Must use key to unlock before moving equipment, or it will alarm.
• Installation is trivial: No wiring, no drilling. Just replace your existing padlock if the shackle fits.
• Common gotcha: The alarm can be triggered by wind or vibration (e.g., a mower on a trailer). Test placement before relying on it for long-term storage.

Should You Buy It

Buy it if you store a lawn mower, ATV, or tools in a shed or on a trailer and want a simple, loud deterrent without wiring or batteries to change. Skip it if you need a lock that can be disarmed remotely, or if your hasp requires a thicker shackle.
