How to open a master lock
One of the most frequent locksmith-related problems is when a person can’t open the lock because they don’t have the key or they forgot a code. All of us probably have been in a situation like that at least once in our lives. In most cases, we can’t open the lock when we’re the busiest and have no time to deal with it. Usually, it leads to panic and stress.
How can you avoid all of that and open a master lock quickly? There are a few ways to do that. You can try picking the lock, bumping it, breaking it, guessing all kinds of combinations, etc. However, trying to resolve the problem yourself might cause more harm than good. So, the most intelligent way to resolve any locksmith issue is to ask for the assistance of a professional. Sure Lock and Key is ready to tell you everything we know about master locks and provide you with our services if needed.
What is a master lock


How do you open a master lock without a key
- First of all, don’t panic and try to look for a spare key if you have one.
- You may try picking the lock. If you have a paper clip, bobby pin, or screwdriver at hand, you may use it to pick the lock. However, we recommend not performing this operation yourself if you haven’t done it before and you’re not confident you can do it accurately.
- You can try to open it with the help of a shim. You can either buy it or make it yourself, from an aluminum can, for example. When you’re using a shim, you’ll need to insert it into the shackle hole, not the keyhole. Start moving it around until it clicks and the lock opens.
- Another option is to break the lock. You may use a drill, hammer, or power saw. Some people use bolt cutters to cut the shackle part. However, we strongly recommend avoiding all these methods as they’re destructive and there’ll be no chance of restoring your lock. You’ll need to purchase a new one.
