Slip the latch, skip the cylinder

Plenty of doors never need a pick. A spring latch with a little play in the frame can be slipped, and that is exactly the job this shove-knife is shaped for. It is a flat stainless blade with a hooked working end and a keyring slot, so it rides on your keys until a latched door asks the right question.

What it is

A pocket shove-knife built for slipping a latch

A shove-knife is the small, stiff cousin of the locksmith's slim jim. The technique is called loiding, also known as shimming or carding: you work a thin, rigid blade into the gap between door and frame, set the hooked end against the angled face of the spring latch, and shove the bolt back into the door until it clears the strike. People have tried the same trick for years with a flexed credit card. The trouble is a card is soft and folds under load. This Lokko blade is cut from flat stainless steel so it stays rigid, drives the latch with a real hooked edge, and slips into the gap the way the technique wants. The handle end carries two finger holes and a keyring slot, so the whole tool lives on your keys.

The job it does

It works the angled face of a spring latch. You slide it into the door gap, hook the latch, then shove the bolt back against its spring until it clears the strike and the door swings.

Where it shines

Spring-latch doors with a reachable frame gap: inner office doors, store rooms, sheds, and older residential latches that were never set up to resist a blade.

The hooked end

That stepped, forked tip is not decoration. It gives you an edge to catch and drive the latch instead of skating off, and the flat body lets you lever against the frame.

How you use it

Three moves, then the door opens

Read the door

Find the latch side and feel for the gap between door and frame. Loiding wants a spring latch you can reach, not a thrown deadbolt.

Slip the blade in

Slide the steel beside the latch and angle the hooked tip onto the sloped face of the bolt.

Shove it back

Press the latch back against its spring while you ease the door. As the bolt clears the strike, the door gives.

Keep it honest: loiding only works on a plain spring latch. A door with a working deadlatch, that little secondary plunger that locks the main bolt when the door is shut, is built specifically to defeat a slipped blade, so it will not loid. For a deadlatched or deadbolted door the route is pin-tumbler work or a different bypass, not this shove-knife. Treat this as a fast, low-cost answer for the many doors that still run a basic latch.

A rigid blade, not a flexed bank card

This is the keyring sibling to our Lokko Credit Card Door Latch Shim, and they split the work nicely. The card is flat and springy and rides in a wallet slot, so it flexes its way past a strike plate. This shove-knife is stiffer and shorter, with a dedicated hooked tip that bites the latch and a body rigid enough to shove rather than flex. If you carry a wallet, the card is the natural pick. If you carry keys, this lives on the ring and is the one that is always in your hand.

The stepped, forked end gives you a leading edge to catch the bolt, and the flat stainless stays put while you lever against the frame. Both tools loid a spring latch. Which one suits you comes down to how you carry.

Build the bypass kit

One blade opens a lot. A small bypass set opens more.

Bypass work rewards a little variety. Different latches, frame gaps, and door weights respond to different shapes, so most people grow this single blade into a tiny kit they can reach for by feel.

MICA Latch Opening Shims

Flexible latch shims in different widths and curves. The natural next step when a stiff blade will not reach a particular latch.

Inflatable Air Wedge

Pumps a controlled gap between door and frame so you have room to work. The wedge makes space, the knife does the slipping.

Credit Card Door Latch Shim

The wallet-carry sibling. Flat and springy where this blade is stiff, so the pair covers both how you carry and how a latch sits.

FAQ

Questions buyers usually ask

What does this open?

Spring-latch doors. That is the angled latch bolt that retracts when you turn the handle. If the door has a working deadlatch or a thrown deadbolt, loiding will not move it, so save this for the many doors that still run a plain latch.

How is it different from the credit card shim?

Same job, different carry and feel. The card shim is flat and springy and rides in a wallet, so it flexes past the strike. This shove-knife is a stiffer, shorter blade with a hooked tip that bites the latch and shoves it back. Wallet carriers tend to prefer the card. Keyring carriers tend to prefer this.

Is it approachable if I am new to bypass work?

Yes. Loiding is one of the most beginner-friendly bypass techniques because the motion is simple: feel the gap, hook the latch, shove it back. Practise on a known spring-latch door or a training setup first and you will feel exactly what the blade is doing.

Does it fit on my keys?

It has a keyring slot at the handle end plus two finger holes, so it rides on the ring as part of your everyday carry. That is the whole idea: the tool is on you when a latched door turns up.

What should I pair it with?

Two companions cover most situations. The MICA latch shims add more widths and curves for awkward latches, and an air wedge opens a working gap so the blade has room to slide in.

Put a real shove-knife on your keyring

Skip the soft, foldable bank card. This rigid stainless blade is shaped for spring latches, rides on your keys, and is ready the moment a latched door turns up. Pair it with a shim set, a wedge, or the wallet-sized card shim as your bypass habit grows.
