What Are the Locking Options for the Glass Patio Pet Door?

This article covers the current V2 Glass Patio Pet Door (released June 2025 onwards).

If you’re unsure whether you have V1 or V2, check our “How Can I Tell the Difference Between V1 and V2 of the Glass Patio Pet Door?” guide before purchasing spare parts or accessories.

Note: This product is not a security door. For better security, we recommend using one of the included semi-permanent locking methods. It is the customer’s responsibility to ensure their door is securely locked.
