Lost your mailbox keys, or the lock stopped turning? A locksmith replaces the mailbox lock fast, so your mail stays secure.
When to Replace a Mailbox Lock
Replace a mailbox lock when you lose the keys, move into a home, or the lock is worn or damaged. A fresh lock and new keys lock out anyone who held an old key.
A locked mailbox you cannot open is the most common reason people call. A locksmith opens the mailbox, then installs a new lock and hands you new keys.
Types of Mailboxes We Service
Chief of Locks replaces locks on all kinds of mailboxes across Indianapolis. Most mailboxes use a cam lock, so the same replacement fits many mailboxes.
- Curbside mailboxes and locking curbside mailboxes
- Wall-mount mailboxes on homes and porches
- Cluster mailboxes for neighborhoods and HOAs
- Apartment mailboxes and mailbox banks
- Commercial mailboxes at offices
Older mailboxes and modern mailboxes both take standard cam locks, so most mailboxes are a quick fix. If your mailboxes use a special brand lock, we match the model. Whatever mailboxes you have, a locksmith can rekey or replace the locks and hand you a set of new keys.
Mailbox Lock Types
Most residential mailboxes use a cam lock, a small round lock with a flat metal cam that swings behind the door to latch it. The right replacement lock must match your mailbox brand and cam length.
- Standard cam locks fit most curbside and wall mailboxes
- USPS-compliant locks meet USPS-L-1172C specifications for security
- High-security mailbox locks resist prying and picking with reinforced parts
- Dust-cover cam locks protect against freezing and debris
- Universal multi-cam replacement locks adapt to various mailbox brands
Good mailbox locks also resist rust and corrosion, and key retention features stop keys from coming out in the unlocked position.
How Mailbox Lock Replacement Works
The lock is usually held in by a nut or a spring retaining clip inside the mailbox. A locksmith opens the door, removes the clip or nut, and slides the old lock out.
The new mailbox lock must align with the cam so the door latches. The locksmith sets the cam, tightens the lock, cuts new keys, and tests the mailbox before leaving.
Different mailboxes need different mailbox lock sizes, so we carry a range of cam locks. For neighborhoods with many mailboxes, we can replace a set of mailbox locks in one visit, and a full set of new keys comes with every mailbox lock we install. Locking mailboxes keep mail safe, so a working mailbox lock is worth it.
Cluster and Apartment Mailboxes
Cluster mailboxes and apartment mailbox banks work a little differently. For a USPS-owned cluster box, the post office holds the master arrow key, and you handle your own compartment lock.
If your apartment or HOA owns the cluster mailboxes, a locksmith can replace your compartment lock and make keys. Check who owns the box first, since a USPS-owned unit is serviced by USPS. You can verify a locksmith through the Associated Locksmiths of America before you hire.
Locked Mailbox: What to Do
A locked mailbox with no key is a common call. Do not pry the door, since bending the mailbox costs more than a new mailbox lock.
A locksmith opens locked mailboxes without damage, then replaces the mailbox lock and cuts keys. Most locked mailboxes are open in minutes, and you leave with a working mailbox and new keys.
Rekey or Replace a Mailbox Lock
Sometimes the mailbox lock still works and you only need new keys. A locksmith can rekey some mailbox locks, but most cam locks on mailboxes are cheap enough to simply replace.
Replacing the mailbox lock is the surest fix after lost keys, since it guarantees no old key opens the mailbox. Every new mailbox lock comes with a fresh set of keys, and the locksmith tests the mailbox before leaving.
Cost of Mailbox Lock Replacement
A standard mailbox lock replacement runs about $45 to $120, including new keys. A high-security lock or a cluster compartment can cost a little more.
