You can attach pictures if there is something you want us to see, like your existing lock, door, window etc. London Locksmiths are a specialist installer of locks and security measures throughout the Greater London area. We offer a pre-planned service working with our clients to achieve the best and most secure results. Most so called 'locksmiths' you find online are looking for customers who find themselves in an emergency. We do not offer this type of reactive service and prefer to take longer specifying the best solution for our client's project.
