Siren Padlock is a metal mandrake manacle

Sirenpdoh.jpg

The “Siren Padlock” adds a 100dB* alarm to a hardened steel and zinc-alloy padlock. The alarm goes off for ten seconds every time the padlock is moved or tampered with, making it difficult to get a pair of bolt cutters around the lock without bleeding from the ears.

Hopefully there’s at least a brief pause before it starts wailing or getting the key into the lock will be a job best left to deaf sleight-of-hand artists.

They’re $20 a pop.

* Or so. There seems to be some disagreement about the true loudness.

    That’s a pretty good price. Most disk locks for bikes run around $20 without the alarm.

    Not crazy about the six month battery life, though.

    Every time it’s MOVED??? Yuck. I can’t wait to park next to a bike on the bike rack that has got one of these wretched things attached….

    Bikes are always being jostled when they’re parked, whether they’re in a crowded bike rack or attached to a lamppost in the middle of a sidewalk.

    I could see the benefits of this if it worked when whacked, or when it felt itself being cut, but just being moved is overkill.

    sleight, not slight

    “Bike rack?” I think this is being misinterpreted. This is not for locking a bicycle, it’s for locking the brake disk of a motorcycle. There’s much less likelihood of accidental motion in that case.
    That said, I like in a large metropolitan area and I am strongly against audible vehicle alarms. They create great annoyance and do little good. When was the last time you heard a car alarm going off and decided to check it out in case it was a theft and you could do something about it? Never? Me neither.

    that should read, sleight(“dexterity”), not slight(“frail”)

    so,if I wrap it in a towel and squirt compressed gas computer duster into the noise hole, will that freeze up the shrieker? Or should I just use a wet towel or a cup of coffee?

    Awesome! Awesome piece of machinery.

    Now: How do I mount twenty of these on my car?

  10. santellana says:

    i foresee unruly teens buying dozens of these and locking all kinds of stuff that does not belong to them just to watch other people being frightened, confused and annoyed.

    also i really want some of these now.

    one morning a sleepy co-worker of mine announced as he was getting a second cup of coffee that he should patent “the car-alarm guided missile”
