You do not need to change locks on your old home, which is the new owner’s responsibility. However when moving into your new home the locks should definitely be changed, this is a priority. This is because the previous owner could have given out and still has spare keys to the house and therefore would have access to just walk in. We can come and change the locks for you! If you look at our service page on our website you will find all of the services which Goldi-Locksmiths offer.
