“Locked myself out on a Sunday evening, keys still inside. Called Crownfield and they were at my door within 25 minutes. Tried picking it first, got it open without any damage. Quoted me £110 on the phone and that's exactly what I paid. Straightforward and honest — exactly what you want when you're standing on your doorstep in the rain.”
“My front door lock had been getting stiffer for weeks and finally packed in completely. Crownfield came the same afternoon, replaced the euro cylinder with an anti-snap one and showed me why the old one was a security risk. Fair price and they didn't try to sell me anything unnecessary. Already passed their number to two neighbours.”
“Very professional service. I manage several properties and needed urgent lock changes after a tenancy ended badly. They handled three doors in one visit, all Yale and mortice, checked alignment on each one before leaving. Reliable enough that I now use them for all my properties.”
Most homeowners don't know what lock they have — only that it locks. Here's a clear UK guide to every common lock type, where each is used, and which actually protects you.
Mortice, cylinder, multi-point or smart lock? A practical guide to choosing the right lock based on your door type, property, and insurance requirements.
Most home insurance policies require specific locks. If yours don't comply, a claim can be refused — even after a break-in. Here's exactly what you need to know.
