Collection: Replacement Ingersoll Lockcases

The Ingersoll Nightlatch Replacement Lockcase is the complete internal mechanism that powers your Ingersoll nightlatch.

Available in Double-Locking (for houses) and Non-Double Locking for apartments and communal doors.
Double-locking provides enhanced security by allowing the user to lock the internal handle from the outside using the key.
This function is not suitable for apartments or communal doors and is only for houses where there is an alterative exit door to use in an emergency.
Non-Double Locking means that the handle cannot be locked and egress is always possible in an emergency.
(both versions auto-deadlock which means that they cannot be ‘slipped’ open but a burglar).

Perfect for homeowners whose Ingersoll nightlatch mechanism has worn out, become faulty, or needs upgrading.
Rather than replacing the entire lock, this allows you to restore full functionality by replacing just the internal mechanism - a more cost-effective solution that maintains your existing door hardware setup.
