Rental properties move fast. Tenants change, keys circulate, contractors come and go. If security isn’t actively managed, risk quietly builds up between handovers.
As locksmiths working with landlords, letting agents, and body corporates across Somerset West and the greater Helderberg, we see the same issues repeat. This guide breaks down what landlords in South Africa should actually be doing to secure rental properties — practically, affordably, and without overcomplicating things.
Why rental property security is a landlord responsibility
In South Africa, landlords have a clear duty to provide tenants with reasonable security. That doesn’t mean turning every unit into a fortress, but it does mean taking sensible steps to prevent avoidable access risks.
From a practical point of view, if something goes wrong and locks were never updated between tenants, questions will be asked — by insurers, body corporates, and tenants themselves.
Security isn’t just a tenant issue. It’s a property management issue.
The biggest security risks landlords overlook between tenants
Most problems don’t come from dramatic break-ins. They come from small, ignored gaps:
- Old tenants still having keys
- Keys handed to friends, cleaners, or contractors
- Copies made without permission
- Garage remotes never returned
- Gates and side doors never checked
If you don’t reset access between tenants, you’re guessing who can still get in.
Rekeying vs replacing locks: what landlords really need
This is where a lot of landlords overspend — or underdo it.
Rekeying
- Keeps the existing lock hardware
- Changes the internal key combination
- Old keys no longer work
- Faster and more cost-effective in most cases
Replacing locks
- Needed when locks are damaged, outdated, or low quality
- Required if hardware no longer meets basic security standards
For most standard handovers, rekeying is sufficient and recommended, provided the locks are in good condition.
Managing keys, copies, and access properly
Key control is where rental security usually fails.
Best practice:
- Issue the minimum number of keys
- Record who receives them
- Avoid uncontrolled duplication
- Retrieve keys and remotes at move-out
- Reset access before new tenants move in
If multiple parties need access (agents, cleaners, maintenance), plan it properly instead of sharing one master key endlessly.
Don’t forget secondary access points
Front doors get all the attention — but they’re rarely the weak point.
Landlords often forget to check:
- Side and back doors
- Garage access into the house
- Sliding doors
- Garden gates
- Storerooms and outbuildings
A property is only as secure as its easiest entry point.
Load-shedding, electronic locks, and backup planning
Electronic locks and motorised gates are common in modern rentals, but load-shedding changes the game.
If your property has:
- Electric strikes
- Access-controlled gates
- Keypads or biometric systems
You need to ensure:
- Manual overrides work
- Backup power is in place where needed
- Tenants know what to do during outages
Failing to plan for load-shedding often leads to emergency call-outs that could have been avoided.
Flats, complexes, and estate considerations
In sectional title schemes and estates, security is shared — but responsibility is not.
Landlords should:
- Coordinate with managing agents
- Understand what the body corporate covers
- Secure internal doors independently
- Reset access even if perimeter security exists
Estate access control doesn’t replace proper lock management inside the unit.
When to involve a professional locksmith
DIY lock changes and quick fixes often create bigger problems later:
- Incorrectly installed cylinders
- Poor-quality locks
- Misaligned doors
- Keys that snap or jam
A professional locksmith:
- Assesses what actually needs changing
- Avoids unnecessary replacements
- Documents work done
- Reduces future call-outs
It’s cheaper to do it right once than to fix shortcuts later.
Frequently asked questions
Do landlords legally have to change locks between tenants?
There’s no blanket legal rule, but failing to manage access can create liability and insurance issues.
Is rekeying enough when tenants move out?
In most cases, yes — as long as the locks are in good condition.
Who pays for lock changes?
Typically the landlord, unless damage was caused by the tenant.
Should tenants be allowed to change locks themselves?
Only with permission and proper key handover. Untracked changes create risk.
Secure the handover, protect the property
Most rental security problems don’t come from crime — they come from poor transitions.
If you’re a landlord, the smartest move is simple:
reset access every time, document it, and don’t cut corners.
Before new tenants move in, review your locks, keys, and access points. Working with a licensed local locksmith makes that process clean, predictable, and stress-free — and saves you from problems down the line.
