Spare Keys: Where People Hide Them and Why it’s a Security Risk

A spare key can seem like a sensible precaution. Whether it’s for family members, trusted neighbours or emergencies, many homeowners like the reassurance of knowing they won’t be locked out.

The problem is that spare keys can also create a security weakness if they’re not managed carefully. Many of the hiding places people consider “secret” are actually the first locations an opportunistic burglar will check.

In this article, we look at the risks associated with spare keys, the common mistakes homeowners make, and the safer alternatives available today.

Common spare key hiding places burglars know to check

The classic spare key hiding places have been around for decades, which means they are well known to burglars too.

Under doormats, plant pots, garden ornaments, fake rocks and wheelie bins may seem convenient, but they offer very little protection if someone is actively looking for a way into your home.

Many criminals are not sophisticated. They simply look for easy opportunities and obvious shortcuts. Finding a spare key can allow them to enter a property without forcing a door or window, potentially delaying the discovery of a break-in.

Action point – avoid hiding spare keys in:

• Plant pots and garden containers
• Under doormats
• Fake rocks
• Wheelie bins and recycling boxes
• Meter cupboards
• Above door frames or window ledges

If a location seems obvious to you, there’s a good chance it will be obvious to someone else as well.

The risks of sharing keys with friends, family and neighbours

Many homeowners leave spare keys with trusted friends, relatives or neighbours. In many cases this works perfectly well, but it is still worth considering how access is managed over time.

Circumstances change. People move house, relationships change and keys can be copied, misplaced or forgotten about. Over the years it becomes surprisingly easy to lose track of who may still have access to your property.

The issue is rarely dishonesty. More often, it’s uncertainty.

Action point – keep control of spare keys:

• Maintain a record of who has a spare key
• Recover keys when circumstances change
• Avoid giving multiple copies to different people
• Review access arrangements periodically

Knowing exactly who has access is an important part of home security.

Safer alternatives to hiding spare keys

Fortunately, homeowners now have better options than hiding a key somewhere outside.

Key safes provide secure storage and controlled access for authorised users. They can be particularly useful for older relatives, carers and family members who may need occasional access to the property.

Smart locks are another increasingly popular option. Depending on the system, homeowners can grant and revoke access remotely, issue temporary digital credentials and monitor entry activity.

Action point – consider alternatives such as:

• Key safes
• Smart locks
• Temporary digital access codes
• Video doorbells combined with remote access management

These solutions offer convenience without creating an obvious security vulnerability.

When should you change your locks?

Many people assume locks only need replacing after a burglary. In reality, there are several situations where changing or rekeying locks can be a sensible precaution.

Lost keys, unreturned keys, property purchases and major household changes can all create uncertainty about who may have access to a home.

While the risk may be low, replacing or rekeying locks can restore confidence and eliminate doubt.

Action point – consider changing or rekeying locks if:

• Keys have been lost
• Keys have been stolen
• You have recently moved home
• Spare keys cannot be accounted for
• Household circumstances have changed
