What You Need

The items you need in this tutorial are easy to find. You can find them in your house or borrow them from your neighbor. You can do this tutorial without the optional tools. However, having all the items will help you finish the steps faster and easier.

1. Current combination number

To open a 4 digit master lock, you need to have your current combination number. It is a random code included in the package once you purchase your lock for the first time. It is very important to secure your combination lock since it would be difficult and time-consuming to crack a combination lock with 4 numbers.

In case you forgot your combination, check if your lock is resettable or not by looking for the serial number. Unfortunately, the manufacturer cannot provide you with a code if it is a lock without a serial.

Some of the methods you can perform to open the lock are cracking the code, applying pressure to the lock, and shimming using a high-grade aluminum soda can.

You can contact the manufacturer if your lock has a serial number. They would ask for your serial number and you need to fill in the Lost Combination Form. Aside from that, you also have to give them a Notary Public so you can prove that you are the owner of the lock. You will receive your combination number in 4 to 6 weeks.

2. Gloves (optional)

If your hands are always wet and sweaty, you may want to wear a pair of hand gloves. A combination lock is sensitive when it comes to numbers. One mistake would require you to set the whole combination digits again.

A pair of non-latex is a good option. Non-latex gloves are gloves not made of latex. People who are allergic to natural latex rubber use this kind of glove as an alternative. When choosing a non-latex glove, make sure that it is not too fit and that it does not easily rip when you pull it out of your hands.

Another option is a pair of powder-free gloves. It is made of latex, however, it has undergone a process called chlorination that removes the powder residues, and at the same time, eliminates the latex proteins. The only problem with this glove is that it is more difficult to remove because of its hard texture.

3. Eyeglasses (optional)

You may need a pair of eyeglasses if you have poor eyesight or the numbers in the combination lock are too small to see. You can use your reading glasses if you have them to make setting the numbers easier.

A pair of adjustable eyeglasses would be very handy if you don’t have regular eyeglasses. This will help in providing the focus you need as you look and read the numbers. You can also adjust the focal length you need.
