FAQ - About our manual deadbolt

Yes! All Finfort locks can be keyed alike — giving you the convenience of one key for front, back, and side doors.

The Manual Deadbolt must be locked and unlocked with a key each time. The Automatic Deadbolt locks itself when the door closes. Manual deadbolts are often used to meet insurance requirements or as a second lock in dual or triple setups.

Yes. It meets British Standard BS3621 and is keyed from both sides — a requirement for most home insurance policies.

Traditional 5-lever mortice locks can’t be keyed alike and use older “Chubb-style” keys. Finfort’s euro cylinder deadbolt is BS3621 certified, more secure, and can be keyed alike across multiple doors.

Pros:

– High security when locked

– BS3621 compliant

– Resists snapping, picking, and drilling

Cons:

– Must be locked manually every time

– Can be forgotten or left unlocked

– Not keyless or fire-escape rated

What Our Customers Say

Shayan

Reliable, secure and aesthetically pleasing
I discovered Finfort locks whilst researching the market for a reliable, secure and aesthetically pleasing lock for my front door. The product offerings looked great and example videos of the lock functions were very useful in deciding which lock to go for. Hilary was very helpful in providing advice and answering any questions I had, she also assisted with putting together a custom package for me which matched my needs exactly.

Adam Cash

Great customer service
When I renewed my home insurance, I found out my old deadlock wasn’t BS3621 compliant. I emailed photos of my door to Finfort and they got back quickly with advice on options and costs — great customer service. I ended up fitting their Manual Deadbolt with solid lockguards — it feels properly secure and looks it too.
