Core Mechanic
Path Through The Maze
Tailpicking is a directional pathing puzzle: move the tail, reach the far end, and clear the pins or tumblers that block the route.

Mouse PI For Hire Lockpicking Guide
Tailpicking looks small until one bad black-safe attempt turns into a real route problem. This page focuses on the checked facts that matter most: how the lock maze works, why spikes are not harmless, when a safe can jam permanently, and how to use typewriters plus save slots to keep a clean run alive.
Main Danger
Black Safes
Timed black safes are the highest-risk lock category because a failed attempt can permanently jam the box.
Safe Habit
Nearest Typewriter
The cleanest current rule is simple: save at the nearest typewriter before you touch any black safe that matters.
Buffer
50 Manual Saves
Public roadmap coverage explicitly lists 50 manual save slots, which is enough to build a cautious lock route on purpose.
How To Read This
Why this mechanic deserves its own page
Lockpicking is not just a minigame you clear once and forget. In MOUSE: P.I. For Hire, it sits right on top of completion risk. The checked sources repeatedly connect safes to schematics, money, and even secret collectible-sensitive rewards, while the broader route literature keeps stressing that the game does not give you a comfortable replay structure later.
That is why this page stays focused on the practical facts: how tailpicking behaves, why black safes are different, and what kind of save structure actually protects your run.
If you are pairing this with a full route, keep the Schematics Locations page and the Beginner's Guide nearby. Locks matter most when they intersect with upgrade routing and missable cleanup.
Risk Logic
The nearest typewriter can be more valuable than the safe itself
A black safe is not dangerous because the puzzle is impossible. It is dangerous because the game lets a bad attempt carry consequences, and the no-replay route context turns that into a real planning problem.
Lock Checklist
The safest tailpicking habits for a clean run
These are the strongest route-safe takeaways from the checked source set. Where a point is more strategy than hard system text, it is written honestly as advice.
Basics
1. Read the lock in short segments
The mechanic gets cleaner when you stop thinking about the whole maze at once. Move a little, clear the immediate pin or tumbler in front of you, then extend the path further.
2. Treat spikes and thorns like hard reset tiles
Current sources agree that the trap layer is real. On basic locks that may only cost time. On black safes, it can cost the entire reward.
3. Expect later locks to get more deceptive
Tailpicking does not stay in tutorial mode forever. Later locks become more branch-heavy and less forgiving, so patience matters more than speed.
Black Safe Rules
4. Save at the nearest typewriter first
This is the most important lockpicking habit on the page. If the safe is black and the contents matter, save first.
5. Respect the reward pool
A failed safe is not just lost cash. Current guide coverage ties safes to money, schematics, and some collectible-sensitive rewards.
6. Do not assume later replay will save you
The broader route consensus is still no comfortable mission replay or level-select cleanup. Handle important safes when the chance is in front of you.
Save Structure
7. Keep one office or post-mission anchor save
This is the slot you do not casually overwrite. It protects your broader route if an individual mission starts getting messy.
8. Keep one mission-start save for collectible-heavy stages
Some locks only matter because of what they are protecting. A mission-start save is the cleanest reset when a whole room chain goes sideways.
9. Keep a dedicated pre-attempt save for ugly black safes
The game gives you enough slots to be deliberate here. Use them. Saving three minutes earlier than necessary is still better than replaying a whole mission path.
Best Pairings
10. Pair this page with schematics routing
When a black safe might hold upgrade currency, the Schematics Locations page becomes the most natural companion.
11. Pair it with the beginner save habits if your issue is discipline
If you keep forgetting to save before locks, jump to the Beginner's Guide. The lock rule only works if the broader save habit is already alive.
12. Use the tips hub for the wider route logic
If you want the bigger picture around `Jack Squat`, shop recovery, and manual-save routing beyond safes alone, move back through the Advanced Tips Hub.
Save Discipline
The 50-slot buffer only helps if you spend it before the mistake
Most lockpicking disasters are not mechanical mysteries. They are planning errors that could have been turned into a harmless retry with one typewriter save a minute earlier.
FAQ
Quick lockpicking answers
How does tailpicking work in MOUSE: P.I. For Hire?
The basic loop is to move your tail through the lock maze, reach the far side, and reset the pins or tumblers that block the path.
Can black safes jam permanently if I fail them?
Current checked guide coverage says the timed black safes are the dangerous category, and a failed attempt can permanently jam the safe.
Should I save before every black safe?
Yes. The safest current rule is to use the nearest typewriter before attempting any black safe you would care about losing.
How many manual save slots does the game have?
Current completion-roadmap coverage lists 50 manual save slots, which is enough to keep office saves, mission-start saves, and black-safe attempt saves at the same time.

The parts most likely to need revision later are black safe reward assumptions, any patch-level change to jam behavior, and any clearer developer explanation of how tailpicking complexity ramps in the back half of the game.
