Worst Places to Keep a Spare Key

The Worst Places to Hide a Spare Key (And Safer Alternatives That Actually Work)

Keeping your home safe is one of the biggest factors in feeling secure and relaxed where you live. Nobody wants to come home after a long shift, a weekend away, or even a quick trip to the shops and find their property has been broken into.

As a local locksmith covering Middlesbrough, Stockton-on-Tees and the wider Teesside area, I see it all the time. One of the most common mistakes I come across is people hiding spare keys in places they think are clever, but burglars already know about.

Let’s go through the worst hiding spots, why they’re risky, and what you should be doing instead.

The Most Common Spare Key Hiding Spots (And Why They Don’t Work)

1. Under the Doormat

This is the classic. And it’s also the first place burglars check.

If you’re hiding a spare key under your doormat, you might as well leave the door unlocked. It’s predictable, obvious and offers zero protection.

When I attend properties after a break-in in Middlesbrough or Stockton, I can tell you from experience that opportunist burglars always try this first.

2. Inside a Fake Rock

Those plastic “realistic” rocks are not as realistic as you think.

Burglars know exactly what they look like. If it’s near the door, in a flower bed or by the gate, it’s getting checked.

These fake rock key safes are widely known and often scream “there’s a key in here” to anyone with experience.

3. On Top of the Door Frame

Another old-school trick.

Yes, it feels slightly more hidden. No, it isn’t secure.

It’s one of the first secondary checks burglars make after the doormat. Plus, retrieving it yourself usually involves standing on something unstable, which is a safety risk in itself.

4. Inside the Meter Box

This is becoming more common around Teesside.

People assume it’s safe because it’s technically “locked.” But most meter cupboards use universal keys. Burglars carry them.

It’s not secure.

The Real Risk of Hiding a Spare Key Outside

When someone finds your hidden key, they’re not breaking in. They’re walking in.

That matters. Insurance companies can question forced entry if there’s no visible damage. If someone uses your spare key, you may struggle to prove a break-in.

It also increases risk to neighbours, especially in shared buildings, flats or apartment blocks across Middlesbrough and Stockton.

The bottom line: the more obvious the hiding spot, the higher the risk.

Safer Alternatives to Consider

Give It to a Trusted Neighbour

This is still one of the safest options.

A neighbour you genuinely trust is far more secure than any plant pot or fake rock. They’re nearby, they can help quickly, and there’s no visible clue that a spare key even exists.

Leave It With a Family Member or Friend

If you don’t want to involve neighbours, choose someone local and reliable.

The key thing is trust. Don’t give it to someone who might lose it or forget about it.

Install a Proper Key Safe (Insurance Approved)

Not the cheap plastic ones.

A professionally installed, insurance-approved key safe is a far safer solution. When fitted correctly, they provide controlled access and aren’t obvious weak points.

If you’re unsure what standard you need, I can advise through my Home and Business Security service.

Upgrade Your Locks Instead

Sometimes the issue isn’t where the spare key is hidden. It’s the locks themselves.

If your cylinders aren’t anti-snap or your mortice locks aren’t British Standard, you’re already vulnerable.

I regularly upgrade properties across Teesside with anti-snap Euro cylinders, 5-lever British Standard mortice locks, reinforced handles, and proper door alignment.

You can read more about this on my Lock Upgrades and Repairs page and my Mortice Lock Replacements page.

What About Smart Locks?

Smart locks and keyless systems are becoming more popular across Middlesbrough and Stockton-on-Tees.

They allow you to grant temporary access, remove access instantly, and avoid physical spare keys entirely.

They’re not right for everyone, but for some homeowners and landlords, they’re a great solution. If you manage rental properties, this may also be relevant: Landlord Locksmith Services.

What To Do If You’ve Already Lost a Key

If your spare key is missing or you’re unsure where it’s ended up, don’t ignore it.

The safest option is replacing the cylinder or lock. I provide 24/7 emergency locksmith services across Middlesbrough and surrounding areas, with clear pricing agreed before work begins.

Final Advice From a Local Locksmith

As someone who attends real break-ins and emergency lockouts across Teesside, I can tell you this: burglars look for convenience.

If they see an easy opportunity, they take it. Hiding a spare key under a mat, rock or frame is convenience for them.

If you’re unsure whether your property is secure, I’m always happy to give honest advice. No pressure. Just practical guidance.
