Replacement Lock

IMPORTANT: If you require an O series, B series or 9 series lock or key (i.e. your key number begins with O, B or 9), these have now been discontinued.

To replace an O series lock you will need to order a 25 series lock as the replacement.

To replace a B series or 9 series lock you will need to order an E, F, G or H series lock as the replacement.

All replacement security locks come with two coded keys for use with your mailbox.

The two keys supplied with the lock are coded specifically for use with each lock – any codes shown in product photographs are for illustration purposes only.

To order a replacement lock – please identify your current mailbox key number and then select the correct lock option before adding it to the basket.

How to find your key number:

Your key number will either start with B, E, F, G, H, 9, or 25 followed by 2 to 4 digits.

To find this, lift the flap on your mailbox and look for the key number label inside - the example image shows key number B360.

Alternatively, if you currently still have a key then the key number is printed on the face of it.

Delivery address:

If you do not have access to your mailbox, we highly recommend sending the key or lock to your work address or a friend or family address.

Otherwise, please add a Note to your Online Order asking for the key to be delivered to your building Concierge for onwards Hand Delivery.

Locks will be dispatched within 3-5 working days and please note that E,F,G & H locks will be delivered by courier and not Royal Mail.
