Door Lock FAQs
Q: Can I install a door locking mechanism myself?
A: Yes, our door locking mechanisms are designed for easy installation. With our step-by-step instructions, you can easily replace the lock yourself. If you need assistance, we’re here to help.
Q: How do I know what lock to get for my door?
A: Your choice of door lock will depend on a few factors including the type of door and also the building type. We recommend speaking to our team if you unsure about what type of lock is right for your needs.
Q: Is changing the locks illegal UK?
A: In the UK, it depends on the role you have on a property. Sole owners can change the locks without needing permission. However, if you are a co-owner, you will generally need the consent of the other co-owners. Landlords have the right to change locks on a rental property but must follow legal procedures, which typically include giving adequate notice to the tenant. Tenants may change locks, but they usually need the landlord's permission and are often required to provide a key to the landlord.
