You will need two basic household tools and about five minutes


Apply a heavy coat of lubricant to the drill bit. This is to ensure that the friction that the drill bit will be exposed to won't break it. Apply the spray lubricant to the inside of the lock.

Push and pull the bit in and out of the keyhole until the trunk pops open.
