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).

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.

Locking Options – V2 Glass Patio Pet Door

1. Temporary (No-Drill) Installation

• Sliding Door Bar Lock (sold separately)

  • Locks the sliding door to the pet door without screws or drilling

  • Ideal for renters or frequent removal

  • Sold via Spare Parts

2. Secure (Semi-Permanent) Installation – Included Parts

Frame Side Install (Brackets Drilled into the Sliding Door Track Frame)

This is the most secure installation method and the only way to properly use the internal or external locking options.

• Use the supplied Frame Bracket Pack and drill the brackets directly into your sliding door track frame.

• This ensures the pet door is firmly fixed and allows full functionality of either internal or external locking systems.
  
  

WARNING: If you are not installing with frame brackets, you must use a separate Sliding Door Bar Lock for semi-permanent locking instead.

• Internal Lock Side

  Reinstall your sliding door’s internal hook directly onto the pet door frame.
  This allows you to lock the sliding door internally against the pet door once it has been securely mounted using frame brackets.

External Lock Side

Use the supplied Lock Bracket Pack to relocate your external catch onto the pet door frame.
This provides external locking access once the pet door is securely fixed in place.

WARNING: To use the supplied Lock Bracket Pack, your sliding door must have external locking hardware that installs perpendicular to your sliding door — meaning the screws must fasten toward the Patio Pet Door frame, not parallel to it.
