You ever seen that old subway vault lock? I’m trying to design a keyless system that still has a solid fail‑safe, but I need to know if there’s a trick or two that can slip past it in a hurry. Your street smarts could help me spot a weakness before I nail it down.

Yeah, those old subway vault locks are tough, but they’re not perfect. If the deadbolt’s stuck, grab a long metal rod or even a sturdy screwdriver, get it into the keyway and pry the latch out—usually a little wiggle will break the lock’s grip. Another trick is to find the worn edge in the keyhole; a flathead on the right angle can slip in and give the bolt enough pressure to pop. Keep a feeler tool in your bag, look for a slight gap under the lock plate, and you can slide a thin blade in, turn it, and the bolt will release. Just do it quick, stay low, and make sure you’re not caught by the alarm or the guards.

That’s a good start, but a quick pry‑and‑wiggle feels risky if the alarm’s wired to motion. I’d rather use a small, low‑profile lever—think a thin, flat metal piece that can slip in the keyway and push the bolt back without jarring the mechanism. If you can slide a felt tip or a tiny brass rod up to the latch and apply steady pressure, the deadbolt will disengage quietly. Also, keep a pair of 0.5‑mm feeler gauges handy; they’re great for spotting that tiny gap where the latch sits. This way you avoid the whole “break the lock’s grip” mess and keep the alarm sleeping.

Sounds slick, but watch the sensors. Those little motion detectors can get a whiff of a metal shim even if it’s just a few millimetres. If you’re going in that angle, use a super thin, heat‑shrinked wire, slide it, twist, then let it slide out—keep the whole thing under a centimeter of contact. And yeah, the feeler gauge trick is solid, just keep it close to the wall so the vibration doesn’t trigger the alarm. Keep it tight, keep it quiet.

Sure thing—I'll keep that wire as skinny as a paperclip and move it like a cat on a hot tin roof. Just one more tweak: I'll use a little rubber sleeve on the tip to dampen vibration before I pull the latch. That should keep the sensors asleep and the job tight.
