The level
of security locks provide can vary. But basically there are three grades of
security:
1 Grade 1: this is the highest grade
security. It is the strongest grade you can get for your residential or
commercial product.
2 Grade 2: this grade is intended for
higher residential security. It is designed and built to offer excellent
security as well as durability. It is mostly used for residential applications
but it can also be used in some light commercial applications.
3 Grade 3: This is basic residential
security. It is the lowest grade of security and the minimal acceptable quality
for residential door locks.
When you
hire a residential or commercial locksmith, I recommend that you let him know where you want your lock to
be. Then you should ask what the best grade lock for that application would be.
I think that for any door inside your house (like the door to the bathroom or
the kitchen) you can use grade 3 but if it is for a lock that will be exposed
to others or the environment (like the front door) you should go for at least
grade 2 for a residential home and grade 1 for a door at a commercial place. Of course the lowest the level of security,
meaning grade 3, the cheaper it will be but remember that going for the
cheapest products will often times lead to risk exposure and the chances of
someone breaking into your home or business will increase. The best you can do
is ask for your commercial or residential
locksmith’s opinion and do as he advises but also make sure that he is
qualified for the job.
