FAQs
What does 'Sold Secure Diamond' rating mean?
Sold Secure Diamond is a high-level security rating awarded by Sold Secure, a independent testing organization. It signifies that the lock has undergone rigorous testing and successfully resisted attacks from professional thieves using a variety of tools.
How much does the SeatyLock Mason U-Lock weigh?
The SeatyLock Mason U-Lock weighs approximately 1.1kg (2.4 lbs).
Can I lock both my bike frame and wheels with this lock?
Due to its compact 'mini-D' size (18cm x 8.5cm inner dimensions), it is best suited for securing the frame to a solid object. You may need to position it carefully, or consider a secondary lock for your wheels if full coverage is desired.
Does it come with a frame mount?
The SeatyLock Mason U-Lock does not typically include a frame mount. Users often transport it in a backpack, messenger bag, or specific lock holster designed for U-locks.
What is the shackle material and thickness?
The lock features a unique triangulated 13.7mm hardened steel shackle.
How many keys are included?
The lock is supplied with 3 keys and a registration card for key replacement.
Is the lock resistant to rust?
Yes, the lock is constructed from rust-free hardened steel and features a UV-protected plastic coating to enhance durability and resistance to environmental factors.
Troubleshooting
Key won't turn in the lock
Ensure the shackle is fully closed and the lock is aligned properly. Check for any debris inside the key cylinder and gently clear it. Try using the graphite lubricant if the mechanism feels stiff.
Lock is difficult to open or close
Clean the key and the lock cylinder. Apply a small amount of graphite lubricant to the cylinder. Ensure the shackle is correctly seated before attempting to lock or unlock.
Plastic coating is scratched or damaged
Minor scratches are cosmetic and do not affect the lock's security. For significant damage, consider using a sealant for protection, though this may not be covered under warranty.

Setup, Compatibility & Care
Setup:
The SeatyLock Mason U-Lock requires no setup other than familiarizing yourself with its locking mechanism. It comes with three keys. It's recommended to register your keys using the provided card, which can be crucial for replacement if keys are lost.
Compatibility:
This lock is designed to secure a single bicycle. Its compact 'mini-D' shape (18cm x 8.5cm inner dimensions) is most suitable for locking the bike frame to a solid, immovable object like a bike rack or sturdy post. Ensure the object you are locking to is thicker than the lock's shackle and cannot be easily cut or bypassed.
Care:
- Keep the key cylinder clean and free of debris. A puff of compressed air can help.
- Occasionally, use a graphite-based lubricant designed for locks if the mechanism feels stiff, but avoid oil-based lubricants which can attract dirt.
- Wipe the exterior plastic coating with a damp cloth to remove dirt and grime.
- Store the lock in a dry place when not in use to prevent rust, although the hardened steel is rust-free and the coating offers protection.
