How to Make a Bump Key Template

Bump keys are a type of lock picking device that you can use to bump, or open, nearly any type of single side spring actuated tumbler lock, as is most commonly found installed in residential home doors and businesses. Making a bump key template will allow you to quickly make a bump key for a specific lock, thereby preventing your having to contact a locksmith.

Things You'll Need

Key blanks
Bump key
Photocopier
Marker

Instructions

- 1
  Place an existing bump key onto the scanner surface of your photocopier, and make a copy. Ensure that the image is not enlarged or shrunk.
- 2
  Place another key blank that you wish to transform into a bump key over the photocopied image. Notice the intervals and the depth of each cut that was made into the bump key; you must transfer these to the new key blank.

  Mark the position and depth of the cuts that will need to be filed down on the key blank.

  File the edges down where marked.
- 5
  Compare the new key to the photocopied image of the bump key by placing the new key over the photocopied image.
