Default Alarm lock

Bought this today at a "mom and pop" hardware store. At $13, I thought the price was quite reasonable.

Searches for it lead me to believe the company is no longer in business though.

It has an alarm built in that detects movement a certain number of times and then sounds a 110 decimal alarm. Resets itself etc.

It uses 9 LR44 batteries which last around 2 years.

I think it is closer to 90 - 100 decibels.

What do you think?

Adding an alarm to a bad lock does not magically make it a good and
secure lock.

Duh. I just noticed another problem. The pot metal lock case does a
fairly good job of blocking the high frequency beeper sounds. So,
holes in the lock case are needed to make the beeper heard. All that
is necessary to silence the beeping is plug up the holes with putty or
wrap the holes with a towel. It could be beeping away merrily and
nobody would hear it while I pick the lock.

In case you did not notice, but it took minutes.

If you tamper or move the lock, it goes off at around 110 decibels.

1. I now know that someone is trying to steal my bike

2. I then decide if I club that person over the head before calling police

3. If I have my swiss army knife with me, I could engage the long blade and practice my knife throwing skills if he has realized his folly and flees the scene.

I think I can make 60 mph.

Try to think before posting.

And in the 2nd video, he disengages the alarm feature by reversing the shackle.

The author gets low points in the I.Q. department.

I give him a 20.

So Jeff.

Do you want to know how I rate your I.Q.?

Do you run outside every time you hear a car alarm? No one
else does either.

Better to save up your money for one of the Abus Granit-X D-lock types, which will succumb only to an angle grinder wielded for an unconscioable time. If you clip the Abus to the seat tube with the quick release clip that Abus also sells (maine came with it) you can use it like a 3-pound hammer to defend yourself against rogue SUVs that come too close.

All the same, I don't carry mine any more. Instead I have a steering lock, called an n'lock, all lower case, a Swiss engineering marvel which makes the bike unrideable by unlocking the handlebars from the steering tube, and is much more convenient than bending over the bike to fit a D-lock.

In between the two proven security devices above in convenience is the ring lock, which is immovably fixed to the frame in the rear triangle and curves around between the spokes when its lever is operated to stop the wheel turning.

You can look up the references for yourself. I'd lay off the snide remarks about Jeff Liebermann, if I were you. Jeff is a very helpful guy, and I can't remember when he was last proved wrong. Certainly, that Jeff thinks you have the wrong end of the stick inclines me to believe the chances are north of eighty per cent that you don't know what you're talking about.

You are entitled to your opinion.

But I feel opinions are like belly buttons. Everyone has one.

I apologize for much of what I said.

You were trying to help with limited knowledge of the actual lock.

You have given me ideas on how to improve the lock.

Like positioning it so it is much harder to break open using a hammer.
