Full details
The Yale 1 Star Euro Thumbturn Cylinder is designed for homeowners and property managers seeking a robust, high-security locking solution for residential or light commercial doors. This cylinder delivers peace of mind through advanced anti-snap, anti-pick, and anti-drill technologies, making it an excellent upgrade for standard door hardware. While it provides exceptional defense against forced entry, users should note that as a 1-star rated product, it is recommended to be paired with a 2-star security handle to achieve the maximum 3-star security standard.

FAQs
What does the 40/40mm size mean?
This indicates the distance from the center of the fixing screw to the outside edge (40mm) and the inside edge (40mm) of the cylinder.
Can I get extra keys cut at a local hardware store?
Because this cylinder uses a patented key system, copies are restricted. You must follow the instructions provided with the key card to order authorized duplicates.
Is this cylinder suitable for fire doors?
Yes, it is rated for FD30 and FD60 fire doors, meeting the necessary safety standards for such installations.
Why should I use a 2-star handle with this 1-star cylinder?
Combining a 1-star cylinder with a 2-star security handle creates a 3-star rated door assembly, which is the gold standard for home security.
What is the benefit of the thumbturn?
The thumbturn provides a convenient way to lock or unlock the door from the inside without needing a key, which is highly practical for fast escapes during emergencies.
Troubleshooting
The key feels stiff or difficult to turn.
Ensure the cylinder is not under tension from a misaligned door frame and apply a small amount of dry graphite lubricant.
The fixing bolt will not catch the thread.
Check that the cylinder cam is in the 'neutral' position by rotating the key or thumbturn slightly until it aligns with the lock body.
The thumbturn does not rotate smoothly.
Check that the door handles are not pressing too tightly against the cylinder housing, which may be causing friction.
Pros and Cons
Pros
- Comprehensive protection against forced entry methods
- Easy internal operation with convenient thumbturn
- Certified for use on fire-rated doors
- Includes three secure, patented keys
- Industry-leading 10-year guarantee
Cons
- Requires professional measurement to ensure correct sizing

- Silver finish may not match all door aesthetics
Setup, Compatibility & Care
To install, remove the existing cylinder by unscrewing the fixing bolt located on the edge of the door face. Measure your door to ensure the 40/40mm size is correct, as incorrect sizing can compromise security and operation. Slide the new Yale cylinder into place and tighten the fixing bolt carefully—do not overtighten, as this can affect the rotation of the cam. No special maintenance is required, though you may lightly lubricate the keyway with a dry graphite lubricant once every 12 months if the operation becomes stiff. Avoid using oils or greases, which can attract debris and gum up the precision pins.
