The Siren Alarm Padlock is a high security key padlock with an integrated 98 db alarm that triggers if anyone tampers with the lock. The device is tagged as heavy duty and can be used as a standard silent lock if you’ve got sensitive neighbours. Another one of those ‘why didn’t they think of this before?’ products. $19.99. Check out the hilarious video which goes through just about every conceivable lock-tastic situation you can think of.
The Heavy Duty Alarm Siren Padlock couldn’t be easier to operate. You can choose between armed and unarmed with a simple twist of the wrist. Once you decide how you want to use the lock (armed or unarmed), simply look at the shackle and place it properly in the Siren Alarm Padlock. The shackle has a notch on both ends. When you insert the shackle into the padlock, you’ll hear a single beep; this means the lock is armed. If you want to use the lock without the alarm, simply turn the shackle around and there will not be a beep.
I wonder how loud it would scream underwater.
That seems like the easiest way to defeat the noise.
