Generally household locks do not need to be routinely changed unless there is a problem. If you are having problems with your locks with them malfunctioning or perhaps you just feel it’s time to upgrade the security to your home; then now might be the time to think about calling us and having them changed/upgraded. For the most part, the only other time we strongly recommend to have your locks changed is if you suspect that someone might have access to your home. Perhaps you’ve just had the builders in that had a spare set or you’ve fired the cleaner that had a set or maybe you’ve had your keys stolen. It’s always worth to err on the side of caution and be on the safe side and make sure your property is secure if you ever suspect that someone may have unauthorized access to your property.
