In order to change a lock sometimes it needs picking or drilling. Vending machines commonly come with a barrel lock. Barrel locks offer high security, but they are expensive. A barrel lock is difficult to pick which means that replacement requires drilling out the vending machine lock and replacing it with another lock. A barrel lock is similar to a tubular lock; a tubular lock can replace the barrel vending machine lock. Most vending machines have a 6, 7 or 8 pin lock. Barrel and tubular locks have radially aligned pins that are not linear.
- Skill level:
Things you need
- Drill bits--1/4-inch drill bit and a small sized bite 1/8-inch bit or smaller
- Masking tape (optional)
- Ruler (optional)
- Large screw driver (optional)
- Needle nose pliers or vice grips (optional)
Check the stability of the vending machine before drilling begins.
Put safety goggles on to protect your eyes from any metal debris in the air during drilling.
Drill a hole in the centre of the barrel lock approximately ¼ inch deep.
Twist tape around the drill bit at the ¼ inch mark. You need to repeat this for each drill cut made into the barrel lock. This is a depth guide that keeps you from drilling too deep into the lock.
Fill each hole drilled with a larger drill bit making a larger hole every time you bore into the barrel lock.
Get to the black pin that holds the lock to the nut in the vending machine by drilling deeper and deeper.
Insert a screwdriver into the hole drilled to twist the lock out of the housing. Use needle-nose pliers to assist in the pulling and twisting.
Decide if you want to put a barrel lock or a tubular lock in the original lock housing. Simply place the barrel or tubular lock in the hole.
Turn it until it clicks into position. Test the key to the lock before shutting the vending machine door to make sure the new lock works and fits properly in the old hole.

- Purchase only one style lock and know the number of pins you want to have before installation.
