Picture of How to open a locked door the Macgyver way.
I learned how to do this when i got locked out of my dorm at BYU-Idaho and it works great!! and all it takes is things you can find in your friends room or from the hall.

Supplies needed:
Vacuum Cleaner
(the pictures are from different doors because my camera is acting wack, but you should get the idea)

Step 1: Tie floss to paper

I stumbled on this method and IT WORKED! I got locked out of my closet and my brother got me in!! Ingenious!! The only thing he changed was he wound duct tape around part of the chord where he thought it would land in the knob.(so it would attach easier)..it took a while and then it popped open! Come to find out that I had 2 purses hanging on the knob which made it even more difficult, but he did it!!

Just fyi, in my experience this only works when the lock is one of those that you push button in to lock, not the general twist the bump on top of the knob type of lock. Sorry if thats confusing...

agreed, we have a twist button lock where the knob locks up, so the rubber cord is not able to turn the knob at all

It took my husband and I about 10 minutes, but it worked! Also, we used ribbon because the floss was locked in the room. Lol

Wow thanks! I also found this site in my quest to open my door. http://openalockeddoor.com. It has a method that only requires a credit card or some paper clips to open locked doors.

Took 3 minutes...

OMG!!! It worked!! I was so desperate so I thought I had nothing to lose but this thing worked. Thank you very much!!

Try using a kitchen knife, that's what my six year old does.

WORKED PERFECTLY. Me and my roomate tried to get into our ex-suitemates empty room with the coat hanger method, but with no luck and hours of hard work. We then saw this instructable and thought we would try it it. Operation door unlock was a success and on the first try.
Just tried it. Got the floss and the cable finally placed after a dozen attempts. However, it's impossible for the cable to get a grip on the handle as i pull it from under the door. The sharp edge of the door is preventing smooth cable movement. But all in all it was fun trying.
Well done, will try it but with a normal foor handle but overall I like the smart idea.

I just thought I should point out but a method that would prob be easyer on this door is to actually just use a credit card or some type of card like that. Since the doors latch has the curved side facing the outside of the room simply slipping a card into place  between the door latch and the jams hole and the door will open with just a push. I have used this method many times on that style door. 
Ya I use that to get in my house when the deadbolts not licked. It's extremely simple lol
I hope you mean when the deadbolts not locked? lol im just kidding, just had to say something :P

you go to BYU-I! it rocks! my dad teaches there and its always great to go and do things up there like the library, the concerts, the gym, the planetarium. OOOO and locking the collage students in their dorms with rope. :-) That is hilarious, but the boys just get ticked, the girls flip out and its way funny. :-)
I'd rather just pick the lock.
I was thinking the same thing. It was one of a few trade skills learned from my youth that have had some benefit, though lawfully, in my adult life. LOL! 
Mythbusters had a Macgyver episode, where they tested things he did. They were able to pick a lock with the filaments from a light bulb.
iirc not the filament, but the wires that support it.  subtle, but significant difference.

it was a halogen light bulb filaments.
unjust norad5 years ago
i believe you misunderstood, or they misspoke.  the filament wire is *very* fine(1-2 thousandths of an inch), , where as the wires that support them are reasonably rigid and more along the lines of 28 gauge spring steel.

look at a clear household light bulb, and you'll see a few heavy wires, and if you look very closely you'll see the filament is actually a twisted coil of very thin wire.  halogens are functionally the same. 

as a locksport enthusiast, and lighting designer, and having dealt with more than my share of broken lamps (bulbs) in that line of work, i can't imagine what you could use the filament for as it's not rigid or strong enough to do anything constructive in a pin tumbler lock.  the supports however could be excellent.

 Tthis is ingenious, but is mostly for dorms.  They have the doorknobs that always turn on the inside, but are automatically locked on the outside.  (so the school can avoid fire safety and theft lawsuits)

Plus, you have your choice of pals from which to borrow the vacuum, floss and paper.

Good method and very creative, but my door has a handle that points down. Just curious if you've ever run into something like that.

I suspect your door handle plate has been taken off at sometime (maybe just to confuse any house-breakers). When you unscrew the door plate you will probably be able to withdraw the square (usually) shaft that goes thru' the door and goes into the other handle socket. Simply withdraw the shaft, turn it round to the desired position and screw everything back as it was! Job done! (You may find the shaft is 'captive' on one side or the other of the door. It will only be held by a little screw. Undo it. Turn the shaft to desired position. Put back together again. Don't forget to put the little locking screw back!) Hope that solves your problem. 


No, it's made that way, so you can just coat hanger it from the outside. Looks like this.

Downward handle as apposed to horizontal handle.

 So it looks a bit like this?
Door Handle of
lobo_pal Ian015 years ago
Yes, but the handle is flat with the door. I'm thinking about a way to use the vent that takes up the lower third of the door.

I'm pretty sure McGyver would have used a paperclip,
but if he ran out, I'm sure he would have done this.

This is creative and looks like it will work. Most vacuum cleaner cords are a little sticky and they can grip the doornknob.

 i once locked my self out of my apartment. i kicked the door in. that was painful. then i locked myself out, again. i kicked the door in, again. my door is really messed up.
greatpanda5 years ago
So...since you've got a vacuum cleaner anyway, you could grab the paper from behind the door by sucking it out, as long as it's got a detachable tube (most do).  Makes me want to go lock something...
=SMART=5 years ago
Haha inventive,

Other ways;
  1. Find the area with the bolt/catch on the door
  2. Make mental note of this
  3. Stand back
  4. Kick area hard with heel of foot
  5. Make sure you are close enough to follow through the kick when the door breaks.
  6. Bingo

 my dorm room door has a dead  bolt on it :( so if I get locked out im skrewed 
tankguy Doldrum5 years ago
 I have an idea, replace the vacuum cleaner cable with a hook of some sort and hook around the handle of the deadbolt and slide it to unlock the door. I just came up with that and haven't tried it but it just might work.
Vanquish5 years ago
Good job, not ideal for outside doors as most have dead bolts
