USPS Cluster Mailbox Regulations
If you live in an apartment, condo, or townhome community, you likely have a cluster mailbox unit (CBU). Here's what you need to know about compliance.
USPS Standards
Technically, the USPS controls mailbox locks to prevent mail theft. Most cluster mailboxes use Arrow locks with standardized USPS keyways. Replacement locks must meet USPS specifications, or the mail carrier won't deliver.
Your Options
- 1.Go through USPS (slow, bureaucratic)
- 2.Go through HOA/Property Manager (if required)
- 3.Call a specialized locksmith (fastest)
Types of Mailbox Locks We Service
Cluster Mailbox Units (CBU)
Common in Kendall apartments and Palmetto Bay condos. We replace individual compartment locks while maintaining USPS compliance.
Wall-Mounted Mailboxes
Older buildings and houses use individual wall-mounted mailboxes. These typically use cam locks or wafer locks. Simple to replace and rekey.
Parcel Lockers
Modern cluster installations include parcel lockers. If you've lost the key the carrier left, we can open the locker and replace the lock.
Private Mailbox Locks
Private mail rooms with individual lockboxes don't require USPS-compliant locks, giving us more flexibility in lock selection.
Curbside Mailboxes
Single-family homes with post-mounted mailboxes. While these rarely have locks, when they do, we can service them.
Our Mailbox Lock Service Process
Secure, legal, and efficient service.
Verification
We verify you're the resident (ID matching address or lease documentation). We won't open someone else's mailbox—that's mail fraud.
Opening
We pick or drill the lock open to access your mail. In most cases, we can pick it without damage, but drilling may be necessary for damaged locks.
Lock Replacement
We remove the old lock and install a USPS-compliant Arrow lock (for cluster boxes) or your choice of lock for private mailboxes.
Key Duplication
We provide 2-3 keys with the new lock. Need more copies? We can cut them on the spot.
Mail Retrieval
You get your accumulated mail immediately and can resume normal mail delivery the next business day.
Why Choose Us Instead of USPS or Your HOA?
Speed
USPS typically takes 1-2 weeks. We do it same-day or next-day. Your mail doesn't sit for weeks.
Convenience
We come to you. No driving to the post office, no waiting in line, no dealing with bureaucracy.
HOA Flexibility
If your HOA allows direct locksmith service, we're much faster than waiting for their vendor approval.
Multiple Keys
We provide multiple keys immediately. USPS typically only provides one or two.
For Brickell condo residents and busy professionals throughout Coral Gables, time matters. We get it done fast.
Common Mailbox Lock Problems
Lost or Stolen Keys
Keys disappear, get stolen, or former tenants never return them.
Broken Keys
Keys break inside locks, especially when older. We extract pieces and replace the lock.
Corrosion
Miami's humidity and salt air corrode locks, making them difficult to turn.
Jammed Mechanisms
Dirt, debris, or bent mail can prevent the lock from turning properly.
Vandalism
If your lock is damaged from tampering or break-in attempts, we replace it immediately.
Key Duplication
Need a spare? We can cut copies of standard and some restricted keys on-site.
