How to Make a Bump Key

First Method

First of all, you have to know about the number of pins in the lock, which you can

identify by listening to the clicks after putting the key in it. Every click means that

there is a pin.

After that, it’s also essential to know the space or distance between the keys. We can

do this by measuring the length of the key. After that, enter into the lock and divide

that number by the number of total pins in the lock.

Discover the slot near the back length of the key. Over this slot, near the key’s teeth,

is the innermost point at which the pins can rest. Mark out this point, utilizing your

ruler down the size of the key. Draw triangular teeth from the points along that line

at which the pins will certainly rest, one tooth in between each groove.

After that, use a file for scratching away all the teeth of the key up. Until the sides

are level with the lines that you’ve previously drawn. If done correctly, the first tooth

of the key should start at the key’s actual end.

Second Method

Here is another method of making a bump key:

Get a blank key from your nearest local store or purchase online. You can get it at a

meager price. It will look like just a normal or any other key but will not have any

teeth cut on it.

With the help of a triangular file, shape the lower level of the key like the extreme

valleys on it to make it a bump key. Congrats, your bump key is ready now.

Conclusion:

It is easy to use a bump key, but you have to take professional and practice advice. With

only practice, you can become a professional in using bump keys, and after that, it will be

effortless for you to bump the locks. If you don’t want to do it by yourself, then you can

call a nearby locksmith professional for this work.
