Common problems with mailbox locks
Small mailbox locks take a lot of use. The right repair depends on the condition of the cylinder and who owns the mailbox.
The only key is missing
You no longer have a working key for your own mailbox and need the lock assessed for replacement.
A key snapped inside
Part of the key remains in the cylinder. We inspect it to see whether extraction is possible without replacing the lock.
The key will not turn
A worn cylinder can become difficult to operate even when the key is fully inserted.
Grit inside the keyway
Windblown Las Vegas dust collects in small keyways and can interfere with the lock's moving parts.
A change of residents
A property owner or manager may want the mailbox rekeyed so previously issued keys no longer operate it.
A shared mailbox unit
For an HOA or apartment-owned cluster, the association or property manager must authorize the work.
What we can do for your mailbox
Cairn replaces and rekeys locks on your own mailbox. USPS-owned cluster units go to the Postal Service. HOA or apartment-owned units require manager or association approval.
Replace a failed lock
When the existing cylinder is worn or cannot be repaired, we can fit a replacement.
Rekey a working cylinder
If the lock permits rekeying and remains in good condition, we change its internal pins to work with a new key.
Assess a broken key
We examine the remaining key and cylinder before deciding whether extraction or replacement is needed.
Check and lubricate
For dusty keyways, we use a dry lubricant made for locks rather than oil that can hold grit.
How mailbox lock work is priced
The $39 service call fee covers travel and inspection and is charged separately. You approve the written price for labor and parts before work starts.
Rekeying or replacement
Rekeying is $22 per cylinder when the lock is suitable. Replacement has a separate hardware cost determined after inspection.
Broken key extraction
Broken key extraction starts from $65 before parts, with the service call fee charged separately.
Condition of the cylinder
A seized or damaged lock may need more work than a functioning cylinder that can be rekeyed.
Number of mailbox locks
The number of cylinders being serviced affects the labor and parts included in the quote.
Location and service hours
Boulder City adds $25 for travel. Calls from 9 PM to 7 AM, on Sundays or major holidays carry a $45 after-hours fee.
How we handle a mailbox lock
First we establish that the unit is eligible for private locksmith work. Then we inspect the lock and explain the available options.
Describe the mailbox
Tell us the address, whether the box is individually owned or part of a cluster, and what happened to the key or lock.
Verify permission
The technician presents identification and a work card, then checks your ID and proof of address or the manager's authorization.
Inspect and give a price
We check the cylinder and explain whether rekeying, extraction or replacement is appropriate. You approve the written price.
Complete and test
We perform the approved work, test the key and locking action with you, and issue an itemized invoice.
What to check before we visit
Mailbox ownership determines who can authorize service. These are the questions worth settling before arranging a visit.
Call (702) 000-0000All questionsCan you replace the lock if I lost my mailbox key?
Yes, Cairn replaces locks on customer-owned mailboxes. We check your identification and proof of address, then inspect the lock and provide the written price before proceeding.
Can you work on the cluster mailbox at my apartment?
It depends on ownership. USPS-owned cluster units are serviced only by the Postal Service, while an apartment or HOA-owned unit requires authorization from the manager or association.
Do I have to replace the whole lock if the key broke inside?
Not necessarily. We inspect the broken key and cylinder to determine whether extraction is possible or the lock needs replacement.
Should I put oil in a mailbox lock that sticks?
Oil can hold the dust and grit that collect in Las Vegas keyways. Graphite or a dry lubricant made for locks is a better choice, although a worn or damaged cylinder may still need repair or replacement.
What do I need to show before you change my mailbox lock?
Have government photo ID and proof of your connection to the address, such as a lease, utility bill or piece of mail. For a managed unit, the owner or manager must approve a lock change.
