Extended Product Information
FAQs
Does this lock meet insurance requirements?
Yes, it is certified to BS 3621:2007, which is the standard level of security demanded by most UK home insurance providers.
Can I install this on a uPVC door?
No, this deadlock is specifically designed for timber doors.
How many keys are included?
The lock is supplied with 2 brass keys.
Is the finish weather-resistant?
The silver finish is durable, but for exterior doors, it should be protected from direct, constant exposure to driving rain.
What happens if I lose my keys?
Due to the 1000 key differs, it is recommended to keep a spare in a secure location as replacements require a locksmith to re-key or duplicate based on the specific lock core.
Is the 10-year guarantee standard?
Yes, the 10-year guarantee covers manufacturing defects under normal usage conditions.
Troubleshooting
Key is difficult to turn
Ensure the door is not warped or misaligned; use a dry graphite lubricant if the pins feel sticky.
Lock will not bolt into the frame
Check that the strike plate is properly aligned and that the door has not dropped on its hinges.

Setup, Compatibility & Care
For proper installation, ensure the timber door is of sufficient thickness to accommodate the deadlock housing. Because this is a BS 3621 lock, installation should ideally be performed by a qualified locksmith to ensure the door frame is reinforced to match the lock's strength. Compatibility is restricted to wooden doors; do not attempt to install on metal or uPVC doors without specific manufacturer guidance. Maintenance is minimal: keep the mechanism lubricated with a high-quality graphite-based dry lubricant once a year to ensure the tumblers remain smooth, and avoid using heavy oils that can attract dirt.
