When it comes to external gates and doors, especially in exposed locations, simplicity often ends up being the most reliable solution.
The Codelocks CL200 Marine Grade is a good example of that approach.
It’s a single-sided mechanical code lock, giving controlled keyless entry from the outside, while the internal free-turning k**b allows straightforward exit without any complication.
Built with a marine-grade black finish, it’s designed to handle harsher environments — resisting corrosion, moisture, and salt spray, which makes it a strong option for coastal areas or anywhere the hardware is fully exposed to the elements.
It’s designed for wooden gates and doors between 35–60mm thick and uses a surface-mounted rim deadbolt, keeping installation relatively straightforward without the need for complex setup.
A solid, dependable option for sheds, side gates, and external access points where you just need something that works and keeps working.
Do you still use many mechanical code locks on external gates, or are digital systems becoming more common on your installs?
