How to Unlock a Locked Snap-on Tool Box

Quck answer

To open a locked Snap-on tool box, follow these steps:

1. Gather the necessary tools: a pry bar, a hammer, and a drill with a drill bit.

2. Position the pry bar at the top edge of the lock and apply pressure to create a gap between the lock and the tool box.

3. Use the hammer to tap the pry bar gently, increasing the gap between the lock and the tool box.

4. Insert the drill bit into the lock and drill a hole through the lock cylinder.

5. Remove the lock cylinder and open the tool box.

6. Replace the lock cylinder with a new one to secure the tool box again.

Remember to exercise caution and only attempt to open a locked tool box that you own or have permission to access.


To unlock a locked Snap-on toolbox, you can do it yourself but be aware that you will need to damage the lock. To order a replacement lock and keys from Snap-On, you will need to be able to read the serial numbers located inside the tool box. It is recommended to order a replacement lock and key with a different model number just in case someone finds your old keys and tries to use them.

Step 1

Check with your friends if they have any spare Snap-On keys. Snap-On only produces a few different types of locks for their tool boxes, so it is possible that a friend’s keys may be able to unlock your box. Before resorting to drilling out the lock, always ask if anyone has a spare key that you can borrow.

Step 2

Find a drill bit that fits into the Snap-On tool box lock. The drill bit should be 2 inches long to ensure that it can completely drill through the lock pins in the tumbler-style lock.

Step 3

Position the drill bit at the top of the keyhole and start drilling with steady pressure. As you feel the top lock pin break, move on to the next one. Continue drilling until all the pins have been broken. Snap-on locks are typically tumbler locks and usually have no more than five lock pins.

Step 4

Insert a flathead screwdriver into the drilled-out keyhole and turn it as if you were using a key to open the lock. If the lock does not open, try using a larger drill bit and repeat steps 1 and 2.
