Living on the best coastline in the country, it's no surprise that short-stay property rentals are booming on the Sunshine Coast, Queensland. With breathtaking beaches, a laid-back lifestyle, and year-round tourism, property owners need the best security solutions to manage guest access efficiently. Two popular options are keyless entry smart locks and restricted security keys. But which is the better choice for short-stay rentals in this stunning region? Let’s compare both solutions.

Keyless Entry Smart Locks

What Are Keyless Entry Smart Locks?



Keyless entry smart locks are electronic locks that allow access without a physical key. They use PIN codes, Bluetooth, WiFi, or smartphone apps to grant entry. Some models also integrate with smart home systems and property management platforms.

Benefits of Smart Locks for Short-Stay Rentals

  1. Remote Access Control – Manage access from anywhere, granting or revoking entry codes instantly.

  2. No Lost Keys – Eliminates the risk of guests losing or misplacing physical keys.

  3. Easy Guest Check-In – Guests receive a temporary code, reducing the need for face-to-face key handovers.

  4. Activity Logs & Security – Track who enters and exits the property in real time.

  5. Integration with Booking Platforms – Some smart locks sync with Airbnb and other platforms, automating code generation for new bookings.

Potential Downsides

  • Power or Connectivity Issues – Some smart locks require batteries or internet connectivity, which can cause access problems if they fail.

  • Higher Upfront Cost – Initial installation costs more than traditional locks.

  • Technical Learning Curve – Hosts and guests may need time to get familiar with the system.

Restricted Security Keys

What Are Restricted Security Keys?

Restricted security keys are specially designed keys that cannot be duplicated without authorisation from the property owner or locksmith. These keys are part of a high-security lock system and offer increased control over who can copy them.

Benefits of Restricted Security Keys for Short-Stay Rentals

  1. Enhanced Security – Keys cannot be duplicated without permission, preventing unauthorised copies.

  2. Long-Term Reliability – No batteries or electronic components mean fewer maintenance issues.

  3. Cost-Effective – Lower initial investment compared to smart locks.

  4. Traditional Access Control – Some property owners and guests prefer physical keys over digital access methods.

Potential Downsides

  • Inconvenience for Remote Check-Ins – Requires a physical handover or lockbox system.

  • Risk of Lost or Stolen Keys – Guests can still misplace keys, requiring lock changes.

  • Limited Access Tracking – No way to monitor exactly when or how often guests access the property.

Which Option Is Best for Sunshine Coast Short-Stay Rentals?

Ultimately, the best choice depends on your property setup and management style. Some hosts even use a combination of both, with smart locks for guests and restricted security keys for cleaners or maintenance staff.
