Product Information
Full details
The Betley Butterfly Rim Deadlock is an ideal security solution for homeowners and DIY enthusiasts looking to secure shed doors, gates, or add a period-style aesthetic to internal doors. This durable double-handed deadlock offers reliable protection in a sleek black finish, though users should note that as a surface-mounted rim lock, it is best suited for applications where the door thickness allows for secure external mounting without recessed mortising.

FAQs
Can I install this on a metal door?
This lock is designed primarily for timber doors. Installation on metal would require specialized fasteners and potentially drilling modifications.
Is the lock handed?
No, it is double-handed, meaning it can be installed on doors that open either to the left or the right.
How do I maintain the black finish?
Wipe the surface with a soft, damp cloth. Avoid harsh chemical cleaners that may strip the protective coating.
Does it come with all mounting hardware?
The deadlock comes with the lock body, strike plate, and two keys. Standard wood screws for mounting are generally required based on your specific door material.
What are the dimensions of the lock?
The unit measures 100mm in width and 75mm in height.
Is this secure enough for a front door?
While it provides a locking mechanism, it is typically recommended as a secondary lock. For main entry doors, it is best paired with a high-security mortise deadbolt.
Troubleshooting
Key turns with difficulty
Apply a small amount of graphite lubricant to the keyway and check if the lock body is slightly misaligned on the door surface.
Deadbolt does not slide into the strike plate
Adjust the position of the strike plate on the door frame to ensure perfect alignment with the bolt.
Lock feels loose on the door
Tighten the mounting screws and ensure you are using wood screws long enough to bite securely into the door core.
Pros and Cons

- Complete kit includes two keys

Setup, Compatibility & Care
Installation of this rim deadlock is straightforward as it mounts directly to the surface of the door and frame. You will need a drill and wood screws appropriate for your door thickness. Ensure that the strike plate is aligned correctly with the deadbolt to ensure smooth operation of the key. For maintenance, keep the internal mechanism lubricated with a light silicone spray once or twice a year to prevent rust, especially if the lock is exposed to outdoor elements. Periodically check that the mounting screws are tight, as timber can expand and contract with seasonal weather changes.
