This isn’t like choosing a residential lock, when you’re looking at the wide variety of products on the market. You’ll want to decide what features serve your business best. There are a number of traits to understand. The complexity of the lock cylinder correlates to the difficulty of picking the lock, the metal content makes a door less vulnerable, the strength of the bolt lets you know how much force it can withstand and drill protection keeps a would-be thief from using a drill bit to compromise the lock. The best thing is to have a local locksmith provide a risk assessment to figure out which aspects you should focus on most.
