Global Secure Logistics Provider

“I received excellent service from the Locksmith who visited to service numerous combination locks.  He also supported staff in rectifying defects and took time to educate me on best practices when attempting combination updates.  Nothing was too much, very supportive and understanding.

“Fantastic work by Thornhill. Retrieved a 400kg Safe from a very rickety first floor location (where it was originally installed by Phil 40+ years ago).  Safe moved to my present home and fitted in a very tricky spot with great care and consummate professionalism. I have since used their safe cracking service on a high end jewellery safe, on which other companies suggested destructive entries.  Drilled and re-keyed by Thornhill, these guys really know their business.”

David Salmond

“Thornhill Security has provided me excellent service on two separate occasions providing access and repair of some security cabinets. The standard of workmanship has been high, and the customer service has been excellent”
