Locking Hardware
1. Check Your Existing Handle and Lock:
Examine the type of handle and lock installed on your sliding door. In some cases, internal locking hardware within the door track may obstruct the proper installation of the pet door.
2. Removing Obstructing Hardware:
If such hardware is present, you may need to remove it to allow the pet door to fit. This hardware is usually secured with screws, which can be unscrewed to remove the components.
3. Consider Security Implications:
Removing the locking hardware may prevent you from securing your sliding door. It's important to weigh this before proceeding.
Tip: Use a Sliding Door Bar Lock as an alternative security solution. It's easy to install and allows you to keep your door secure without relying on the original lock.
