What we sort out

Mailbox locks, and the usual reasons

How it goes

What happens when you call

1

Say what type it is

Single box, bank of boxes, or a lock box — and whether the box is yours or belongs to USPS.

2

Price before we come

You hear the cost of the opening and any new cylinder before we set out.

3

Opened and secured

We open it, fit a new cylinder or rekey, and check the new key works with you.

Before you call

Have photo ID and something tying you to the address — a lease, a closing statement or a utility bill. If you rent, check whether your lease wants the landlord told. Note the nearest cross-streets for the technician, and tell us if anyone is inside who needs help.

While you wait

Do not force the door or attack the lock — that is how a quick opening becomes a replacement. If the property is standing open, or something is damaged, say so on the call and we will treat it as priority.

Straight answers

What affects the price

Single box or bank

One mailbox is a quick job. A bank of boxes takes longer, and we price it per box.

Open, rekey or replace

Opening is one price and a new cylinder another — we tell you both before we start.

Who owns the box

USPS-owned cluster boxes are handled by USPS for some problems. Tell us and we will say which you are.

What is fitted

Standard USPS-style cylinders against heavier cam locks on lock boxes and gates.

Questions

Mailbox questions

Can you open a mailbox without the key?

Yes, and in most cases without damaging it. If the lock is corroded or already broken it may need replacing, which we tell you before we start.

Can you rekey a mailbox?

Yes. The old key stops working and you get a new one — usually less expensive than a full replacement.

Do you work on bank-of-boxes units?

Yes — individual boxes within the bank, and several in one visit. Tell us how many boxes.

My box belongs to USPS — can you still help?

Sometimes USPS handles it and sometimes the owner does. Tell us when you call and we will say which you are.

Can you match the mailbox to my house key?

Often yes. Have the house key with you and we will see what the cylinders allow.

How long does it take?

A single mailbox lock is quick. A bank of boxes takes longer and is usually still a single visit.

Mailbox lock giving you trouble?

One call and we will open, rekey or replace it properly.
