DO I NEED A LOCK?
We will always advise you on the best and safest route to take when ordering replacement keys and locks. If you are new to a property that has previously been occupied then we suggest you change your lock as the previous occupiers may still hold keys.

HOW DO I FIT A RENZ MAILBOX LOCK?
Replacing the mailbox lock is straight forward and requires a basic level of DIY skill. Please use the following instructions to guide you through the process, or give us a call for any advise.

Important: Please work in a safe manner using relevant PPE guidelines (safety glasses & gloves)

• Fit a 3.5mm diameter steel drill bit in a power drill to use.
• Place the drill bit into the hole of the lock (be careful not to damage the body of the mailbox), drill straight and apply consistent pressure.
• Drill into the lock to a depth of approximately 16mm. Once you have reached this depth, the internal pins will start to break down and you will feel the lock work a little loose.
• Remove the drill and insert a small screw driver.
• Twist the screw driver until the lock releases and the door opens.
• The lock does not open – drill further into the lock and repeat.
• Once the door of the mailbox is open: Using a screwdriver, pry the small cap from the rear of the lock.
• Remove the washer between the cap and the CAM arm– Remove the ‘CAM’ which holds the door closed.
• Remove the securing clip which tightens and secures the lock to the body of the mailbox.
• Place the new lock into the lock hole.
• Fit the securing clip to the lock.
• Using the new keys, check that the lock is now securing the door.
