Alarm Lock 110dba Universal Security Alarm Lock System Anti-Theft for Door Motor Bicycle Padlock with 3 Keys (2PCS)

What It Is

This is a high-decibel (110 dBA) security alarm lock designed to deter theft of lawn mowers, ATVs, bicycles, doors, and padlocked equipment. It combines a mechanical padlock with a motion-triggered alarm that sounds when tampered with.

Fitment & Compatibility

• Not mower-specific: Works on any item with a standard padlock hasp or shackle loop up to 3/8" diameter (shackle clearance ~1.18" wide, 0.87" deep).
• Check hasp size: Measure your mower’s locking point (e.g., handlebar holes, deck hasp, or storage shed hasp) to ensure the shackle fits through.
• No brand/model limits: Fits most push mowers, zero-turns, tractors, or ride-ons with a hasp or chain loop. Not designed for OEM keyed-alike systems—aftermarket only.
• Battery: Requires 2x CR2032 coin cells (included). Replace when alarm weakens.

Key Things to Do Before Buying

• Alarm sensitivity: Motion trigger is adjustable but may false-alarm from wind or bumping. Use the included “sleep” mode (10-second delay) when storing in a garage.
• Weather resistance: IP44-rated (splash-proof), but not submersible. Avoid leaving it in heavy rain or pressure-washing.
• Key quality: Keys are basic brass—consider adding a spare or lubricating the lock cylinder annually.
• Installation: No tools needed; just attach to hasp or chain. Test alarm volume in your environment (110 dBA is loud but may be muffled indoors).

Should You Buy It

Buy this if you need a cheap, loud theft deterrent for a lawn mower or gear stored outdoors, especially in low-risk areas where a visible alarm might scare off casual thieves. Skip it if you want a permanent, integrated solution or need weatherproofing for constant rain exposure.
