Haven't used them but it's misleading to say they are open 24 hours, as the shop is open 8-5 M-F only. So if want a security key cut on a Saturday morning, tough! :)

I am very pleased with the welding and fixing of the broken lock plate onto our Victorian gate, by Robin. I would describe the final result as "invisible mending". Robin came on time was professional and friendly.

I decided to contact YY Security in Hammersmith after not being happy with the customer service I received from two different locksmiths (I did not receive quotes for the lock replacement as requested) . I was very pleasantly surprised when I was treated as a customer should be. I accepted the YY Security quote for the work on the door and the work was done as agreed. I am a very happy customer.
