What to Do If You’ve Lost Your House Keys: A Step-by-Step Guide

July 7, 2026

Losing your house keys can happen to anyone. Whether they’ve slipped out of your pocket, been left somewhere, or disappeared altogether, it can quickly turn a normal day into a stressful one.

Before you panic, take a deep breath. There are a few simple steps you can take to regain access to your home while protecting your family’s safety and security.

At Premier Locksmiths, we’ve helped countless Cape Town homeowners through this exact situation. Here’s what we recommend.

Step 1: Stay Calm and Retrace Your Steps

Before assuming your keys are gone for good, take a few minutes to think about where you’ve been.

Ask yourself:

Have you checked your pockets, handbag, or car?
Could they have been left at work?
Did you leave them at a friend or family member’s house?
Have they fallen between car seats or under furniture?

It’s surprising how often keys turn up after a careful search.

Step 2: Check if You Have a Spare Key

If you have a spare key:

✔️ Ask a trusted family member or neighbour if they have it.

✔️ If you use a secure key safe, retrieve your spare from there.

Avoid hiding spare keys under doormats, flower pots, or fake rocks. These are the first places opportunistic burglars look.

Step 3: If You’re Locked Out, Call a Professional Locksmith

If you’re unable to gain access, resist the temptation to force the door or climb through a window.

Trying to break in yourself can damage doors, locks, windows, or frames—and often ends up costing far more than calling a professional.

At Premier Locksmiths, our emergency call-out team can help you regain access quickly and with minimal damage.

Step 4: Think About Your Security

Once you’re safely back inside, ask yourself one important question:

Do you know where your keys were lost?

If your keys were simply misplaced inside your home, your security risk is low.

However, if they were lost in a public place—or stolen—it may be possible for someone to identify your home and gain access.

In these situations, it’s worth considering improving your security.

Step 5: Should You Rekey or Replace Your Locks?

Many homeowners assume they need to replace every lock after losing their keys.

In many cases, that’s not necessary.

A professional locksmith can advise whether it’s better to:

🔑 Rekey your locks

This changes the internal mechanism so your old keys no longer work while keeping the existing lock.

This is often the quickest and most cost-effective solution.

🔒 Replace your locks

Replacement may be the better option if:

Your locks are old or worn
You want to upgrade to high-security locks
You’re considering smart locks or access control
Your current locks have been damaged

Our locksmiths will assess your situation and recommend the option that best suits your home and budget.

Step 6: Prevent It Happening Again

Once everything is sorted, take a few simple steps to avoid another lockout.

Consider:

Having a spare key professionally cut
Leaving a spare with someone you trust
Installing a secure key safe
Upgrading to a smart lock or keypad entry system
Labelling your house keys without including your address

Small changes today can save you a great deal of stress tomorrow.

Bonus Tip: Check Your Doors and Locks

If you’ve recently struggled with your keys, it’s also worth checking that your doors and locks are operating correctly.

Sometimes a lock isn’t faulty at all—the issue is a misaligned door, worn hinges, or a strike plate that’s shifted over time.

Because Premier Locksmiths also offers home maintenance services, we can assess both your locks and the condition of your doors to ensure everything works smoothly and securely.
