One of our locksmiths recently attended a job the customer had lost the key for the back wooden door in his North London home. The property in Finchley, was fitted with a 5 lever sash lock. Our locksmith opened the existing lock and replaced it with a British standard (bs 3621) insurance approved sash lock, which came with 3 keys.
It is a good idea to check if all your locks are insurance approved as you may not be insured if your locks are not compliant. Not sure? Why don’t you book a free security survey from one of our Finchley locksmiths. Call us on 0800 052 0775.
