How do I open a lock with no key?

Question

I locked myself out of my home office. I have tried picking the lock with a paper clip, and a DIY tension wrench. I have also tried using a card to open the door. It appears to be a standard doorknob lock like on my front door. I don't mind destroying the doorknob (with a drill or otherwise), I would just prefer not to destroy the door or call a locksmith.

Answer 1

By now, it should have past 15minutes, I believed you got it opened. If not, try to hammer the doorknob, but you have exercise the correct strength as not to damage the door. Strike directly strong enough & a few try will do.

Answer 2

take a 1/2" drill bit and start drilling the lock, once it grabs the metal, it will twist the lock open, usually takes about 2 seconds

Answer 3

You need a flat piece of bendy metal, bit thicker than paper clip. You will have to bend it into a jagged zig zag shape like this

^^^^^^^^^^^^^ Then you push it in the lock at an angle, pushing it upwards, then push down hard and twist, and it should open.

We have a door in our house with a lock, but we have no key, it got lost years ago, and every now and then it gets locked by accident, so iv mastered the art of opening it now!!

Answer 4

I am sure you are not going to misuse the technic.

There are leavers in each lock at left and top of key hole. Which can be activated by a thin-hard angled wire.

It is in traditional locks only and use the technic at your own risk.  The Locks opened by this technic, will not be defective.

Answer 5

Well what kind of door is it? Can you find a picture off of Yahoo or Google?

Answer 6

if you drill it . It will bite, so hold the drill tight. There is also a chance breaking the drill bit.
