Our locksmith in NW6 was called out to replace a Chubb lock and a Yale lock in Kensal Rise, North London. Both locks had become worn and increasingly hard to open because of badly cut keys in the past. Badly cut keys can cause locks to wear unevenly and can even result in you being locked out. Our local Locksmith replaced both licks with new keys and advised the customer to use original keys whenever getting keys duplicated as this will reduce the risk of keys being different in future.
