Introduction: How to Open Doors With an L-Slide

L-Slides are neat, simple tools that can let you open a closed door. Locked out? L-slide!

Step 1: Create Your 'Slide

The method of choice is to scrounge up some brick-strap, which usually floats around construction places.

Use pliers (to bend the metal back and forth along a line until it shears) or bolt cutters, to cut the length you want.

Then, bend the brick-strap to a ninety degree angle, creating an "L" with one longer side and one shorter side.

Use any method available to you to pound the angle flat.

Step 2: Practice

Keep your eyes peeled for one that opens towards you, with the curved side of the latch facing away from you, and a good amount of space between the faceplate and the strikeplate.

Slip the long side of your slide through the door.

Work the slide towards you.

Use your other hand to pull on the door so that when the latch is out of the hole in the doorjamb , the door pulls open - Voila!

Sometimes a door latch will be stiff - wriggling, shaking, or agitating your slide might help.
Occasionally, you can use the slide to ratchet open the door by wiggling it left-to-right.

Some doors have lock-out pins, just above the latch, to make the latch immobile if the lock-out pin is pressed in. So always come up from the bottom!

Some doors have slide guards - get to it later, once you understand the basic principles.

If these coaxings don't help, practice on a different door.

Worthless on a deadbolt.

Yeah!! bump Key was wondering if someone would come forward with that way to go edrainkona :D I bumped the police dept. once there so lame.

I've tried this on many different types of doors, and i have yet to see this work. the beveled part of the latch that you need to get the slide into is too far into the door jamb. It's a good idea, but not very effective.

Bit late on this wagon, but thought I should point out, MOST exterior doors open into the building! Some double French doors are hinged to open out, but as noted, they have a strip covering the lock stile gap, blocking access from a slide.

I made something kinda like this out of my old school ID (made just like a credit card). This mostly works on doors inside buildings (like a teachers classroom) or on doors that aren't as important to keep locked. For example, this would never work on the main door to my house as it has 2 dead bolts on it, but it works on doors inside my old school. Long story short, I was showing a friend how to do it. I opened the door, but he was tired of standing and waiting for our teacher to come to unlock the door and he went inside. We both got an office referral and couldn't do any "fun" stuff they plan for us at the end of the year. This was about 2 weeks before the last day of school. There wasn't anything against it in the rules book. I even asked the principal to tell us what rule we broke, and she couldn't :P

I used to do that to get into a class room, only thing is we were allowed to be in there, just didn't have a key. We had gotten into the building bay having one of the maintenance men unlock the outside door.

i think that was "breaking and entering"

Yeah...I know all about that...I used to carry a couple of picks and a tension wrench for lockpicking around with me, but I was never any good at it... I did, however, find out that you can use the tension wrench in almost the exact same way this instructable describes. Got caught, though. Stupid PIC left his damn book in the room. One week suspension...grounded at home for a month-ish.

yep. which still wasn't anywhere in the rule book :P or maybe it's against state laws and theres something about following state laws, but thats the only thing i can think up without hurting my brain.
