How to Pick a Lock: Step-by-Step Guide

Searching for how to pick a lock usually comes down to two questions: is it legal, and could someone do it to your door? Picking a lock you own is not the same as picking one you do not, and the law treats intent and permission very differently. We do not teach technique on this site, but we explain the legal picture and how to make your locks harder to beat.

Key points

  • Picking a lock without the owner’s permission can lead to criminal charges, and rules on owning tools differ between states.
  • In NSW, working as a locksmith requires a Class 2 security licence; ask any locksmith for their licence number.
  • This guide gives no picking technique; it covers legality, risk and upgrades that make forced or covert entry harder.
  • A deadbolt typically costs about $290 to install in Sydney, and re-keying typically costs about $75 per lock.

The short answer is that the act depends on who owns the lock and why you are doing it. This is general information, not legal advice, so check your state’s laws or speak to a lawyer for your situation.

Lock pick, lock picks and picking sets in Australia

A lock pick is a tool made for working a lock without its key. Sold as a set, picks are marketed as a hobby product, but that does not change how the law treats misuse.

  • Lock picking set Australia searches: many appear on hobby sites, and availability changes, so we cannot confirm what any shop stocks.
  • Pick guns and kits from big retailers: listings for a lock pick gun at Bunnings or a lock pick set at Kmart change often; check the retailer directly.
  • Possession laws: they vary by state and often turn on intent, so buying a set does not make carrying it risk-free.
  • Insurance: a break-in involving no forced entry can raise questions with insurers, so ask your insurer what locks they expect.
  • Licensed locksmiths: they carry specialist tools as part of their work and are expected to check ID before opening a home or car.
  • Hobby locks: if you want a puzzle, buy practice locks and keep them at home instead of experimenting on your front door.

Why quality locks resist picking

You do not need to understand the technique to understand the defence. Better hardware makes covert entry slower, harder and noisier.

  • Tighter tolerances: well-made cylinders from makers such as Lockwood, Abloy and Lane leave less room for covert manipulation.
  • Worn pin tumblers: older, heavily used locks, and keys copied too many times, wear and loosen over time.
  • Restricted keys: keys that cannot be copied freely reduce the spread of working copies; see our restricted key systems guide.
  • Cheap knob locks: rental properties often have basic hardware that gives little resistance, so upgrading entry doors is worthwhile.
  • Door and frame strength: most break-ins attack the door, frame or strike plate, not the cylinder.
  • Layering: a deadbolt plus a quality latch is harder to defeat than either alone.

Upgrading security instead of learning how to pick a lock

Upgrade (Sydney, Oct 2026)Typical costBest for
Deadbolt installationAbout $290 ($170–$460)Front and back doors with only a latch
Re-key, per lockAbout $75 ($52–$140)New home, lost keys, ending old copies
Basic lock replacementAbout $255 ($140–$400)Worn or damaged locks
Smart or digital lock, supplied and fittedAbout $600 ($345–$920)Keyless entry and code control
  • Start with the entry doors: front, back and garage-access doors give the most security per dollar.
  • Check strike plates: after a house settles, misaligned plates and short screws weaken the lock.
  • Compare lock types: our types of door locks guide sets out the options.
  • Consider keyless entry: see our smart locks guide for what to check first.
  • Re-key or replace: our rekey vs change locks guide explains which suits you.
  • Store spares safely: a key safe or lock box beats a hidden key under a pot plant.

Locked out? Skip how to pick a lock and use these options

  1. Check other entries you are entitled to use: a door or window you know is unlocked and that is yours to use.
  2. Contact whoever holds a spare: a partner, housemate, neighbour or family member.
  3. Call your landlord or agent if you rent; they may hold keys or approve a locksmith.
  4. Call roadside assistance if you are locked out of a car, as some memberships include lockout help.
  5. Book a licensed locksmith: expect an ID or proof-of-residence check before they open a home or car.
  6. Know the cost: a business-hours house lockout typically costs about $205 ($140–$345); read our locked out of house guide and locksmith cost guide.

Lock pick questions about keys and copies

  • Key cutting: a standard key typically costs about $14 to cut ($6–$34); see our key cutting guide.
  • Car keys: a replacement cut and programmed typically costs about $345; see our car key replacement cost guide.
  • Safe opening: opening a safe or resetting a combination typically costs about $400 and needs proof of ownership.
  • Broken key: extraction typically costs about $150, which is usually cheaper than a new lock.
  • After hours: weekend and public-holiday call-outs carry a surcharge that varies by locksmith.
  • Licence: a legitimate locksmith holds a Class 2 security licence, so ask for the number.

Common mistakes to avoid

  • Buying a set to get into your own home: you risk damaging the lock and the door; call a licensed locksmith instead.
  • Carrying picking tools in public: intent matters in law, and carrying them can create serious trouble.
  • Trusting a cheap lock because it looks solid: weight and shine say little about internal quality.
  • Hiding a spare key outside: obvious spots are the first places a thief checks.
  • Ignoring who has copies: if you cannot account for every key, re-key the lock.
