  • Royston – Cerberus Security locksmiths are NOT a pop up firm!

    Cerberus Security locksmiths have been serving Cambridgeshire and the surrounding areas including Royston, from the same location in Sawston since day one. Furthermore we have never changed our trading name or phone number and we will always be contactable should you need us to honour our promise.


    From our head office located in Sawston, we are able to cover a wide area with an excellent response time, including Royston.

    Some of which include Royston, Sawston, Pampisford, Whittlesford, Babraham, Stapleford, Great Abington, Duxford, Great Shelford, Little Shelford, Hinxton, Little Abington, Linton,  Balsham, Hauxton, Thriplow, Ickleton, Harston, Foxton, Great Chesterford, Trumpington, Fowlmere, Melbourn, Ware, Shepreth, Cherry Hinton, Fulbourn & Little Chesterford to name but a few!


    Royston locksmith – We are physically located in Sawston and are not a call centre 200 miles away claiming to be local!

    Do not be fooled by these pretenders! Firstly, some of these firms do not have a single locksmith in their employ. Furthermore, they promise you an engineer within the hour before even beginning calling locksmiths in your area. We know this as they call local firms such as ourselves asking us to cover the job for them. Consequently, if they cannot find someone they will wait for you to call asking where is your engineer? As a result, they then make some excuse, “his van broke down,” at which time it may be too late to find another that is actually local to Royston.

    Consequently, if you use a national call centre that employs no locksmiths of their own, who comes to your aid if there is a fault? Hence we are one of the few genuinely local firms to be able to probably serve Royston’s residents.

    Finally, we offer discounts for senior citizens, students and happy friendly customers are available at the engineers discretion. Therefore, try offering him a cuppa to sweeten your chances ;D.’
