Keys and locks

If you’ve misplaced your post box keys or need a replacement lock, we’re here to help. Whether you need a spare key or a brand-new lock, our high-quality replacements ensure your deliveries stay safe and protected.

Frequently asked questions

If you already know your key number, please go to our order key page  and select your key number required from our series key range. If you do not have a key number, then you can only purchase a replacement post box lock. For security reasons, we do not hold a record of key numbers for post boxes and cannot provide any historic information on previous key numbers for your post box.

If you hold an E, F, G, or H-series key, please go to our replacement locks page and select the correct option before adding it to your basket. However, if your key number begins with B or 9, please note that these products have been discontinued – you will need to order an E, F, G or H-series lock as a replacement.

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

We’re here to help – just email mailboxkeyorders@bellsure.co.uk with a picture of your post box or key, and we’ll advise which replacement lock or key you need.

Unfortunately, we do not offer an installation service for replacement locks. We recommend contacting a qualified locksmith who will be able to fit a new lock securely and safely for you.

For security and logistical reasons, we ask that replacement locks or keys are sent to an alternative delivery address – not the address of the post box. This ensures you can access your order without needing the key or lock you’re replacing.

In stock keys are despatched within 2-5 working days. Out of stock keys are fulfilled from our overseas warehouse which may take 2-3 weeks to arrive.
