Losing the key to your shed is frustrating, but there are several practical ways to regain access without causing unnecessary damage. Rather than attempting to pick the lock yourself — which is harder than it looks and can damage the lock — it's worth knowing all your options first. Here's a straightforward guide for NZ homeowners.
Why Lock Picking Is Harder Than It Looks
You might have seen lock picking demonstrated online and thought it looked simple. In reality, picking a lock successfully requires specialist tools and significant practice, even on basic padlocks. Attempting it with improvised tools (like bobby pins or paperclips) on a modern lock is very likely to:
- Damage the lock pins, making it harder for a locksmith to open later
- Break your improvised tool inside the keyway, jamming the lock completely
- Take far longer than a professional alternative
For most homeowners, lock picking is not a realistic DIY solution. The good news is there are better options.
Check the Obvious First
Before doing anything else, run through this quick checklist:
- Check all your key hooks and drawers — shed keys are notorious for ending up in unexpected spots
- Ask other household members if they've seen or used the key
- Look for a spare key you may have cut and forgotten about
- Check if any windows or a back door on the shed are unlocked — always try the simplest option first
- Contact the shed manufacturer if it's a newer kit shed; some suppliers can provide a replacement key using the lock's serial number or key code stamped on the lock body
Practical DIY Options (Without Picking)
If you've confirmed there's no other way in, here are legitimate approaches a homeowner can try themselves:
1. Remove the Padlock Hasp or Hinge Screws
If your shed uses an external hasp and padlock, check whether the hasp screws are accessible from outside. If so, you can simply unscrew the hasp to open the door, then replace it with a better-secured hasp afterwards (one where the screws are hidden when the hasp is closed).
2. Use a Bolt Cutter on a Padlock
For a basic padlock securing a shed, a bolt cutter is often the most practical solution. A decent bolt cutter from Bunnings or Mitre 10 will cut through most standard padlock shackles. This does destroy the padlock, but padlocks are inexpensive to replace and this is far less damaging than forcing the door.
- Use the largest bolt cutter you can get — the longer the handles, the more leverage
- Position the cutter jaws on the shackle as close to the lock body as possible
- Safety note: Wear safety glasses, as metal shards can fly on cutting
3. Drill Out the Lock
As a last resort for a built-in door lock (rather than a padlock), you can drill out the lock cylinder. This destroys the lock but leaves the door and frame intact. Use a sharp HSS (high-speed steel) drill bit, starting with a smaller pilot hole, and drill directly into the centre of the keyway. You'll need to replace the lock cylinder afterwards. This is a job that's doable for a competent DIYer but does require care.
Replacing the Lock Afterwards
Once you're back inside, it's a good time to upgrade your shed security. Consider:
- A closed-shackle padlock (the shackle is mostly hidden, making bolt cutters much less effective)
- A disc lock for high-security applications
- Cutting a spare key immediately and storing it somewhere safe (not under a flowerpot!)
- Fitting a key safe to an exterior wall so a spare is always accessible
You can find a good range of padlocks and security hardware at Bunnings, Mitre 10, or PlaceMakers.
A Note on Legality
It is legal to pick, drill, or force a lock on property you own. However, be aware that doing this on a lock you don't own — including a rental property — may be unlawful and could breach your tenancy agreement. Tenants should contact their landlord first; landlords have obligations under Tenancy Services rules around locks and access. If in any doubt about your rights, check with Tenancy Services before proceeding.
When to Call a Professional
In many cases, calling a licensed locksmith is genuinely the fastest and cheapest option, especially if:
- The shed contains valuable tools, equipment, or chemicals you need urgently
- The lock is a higher-security cylinder lock built into the door
- You want to avoid any damage to the door or frame
- You're not confident using bolt cutters or a drill safely
A professional locksmith can often open a basic shed lock non-destructively in minutes, and can rekey or replace the lock on the spot. As a rough guide, a callout for a simple shed lockout typically costs less than buying specialist lock-picking tools yourself — and the locksmith will do it properly.
