When you can't get into your mailbox
If any of these describe what you're dealing with right now, this is the service you need. Call with your situation and location - we'll confirm we can help before sending anyone out.
You Lost Your Mailbox Key
Mailbox keys are tiny and easy to lose. Without it, your mail piles up and anyone could be fishing through it. We open the box without damage, install a new lock, and give you fresh keys.
Lock Is Jammed From Weather
Mailboxes sit outside in rain, snow, salt, and humidity year-round. The tiny lock corrodes and seizes up. We replace it with a weather-resistant cylinder that handles the elements better.
You Moved In and Don't Have a Key
Previous owner or tenant never left a mailbox key. You have no idea who else might have one. We replace the lock entirely so you're the only one with access to your mail.
Someone May Be Stealing Your Mail
If your lock shows scratches, feels loose, or your mail has been disappearing, someone may have tampered with it. A new lock stops that immediately and protects your personal information.
Describe your situation - we'll confirm the right service and come prepared.

Mailbox Locks Are Different From Door Locks
Mailbox locks use tubular or wafer mechanisms that are much smaller than standard door locks. They need specific tools and specific replacement parts. We carry the right cylinders for curbside boxes, wall-mount units, and community cluster mailboxes so we can handle the replacement in a single visit without ordering parts.
Protect Your Mail, Protect Your Identity
Your mailbox receives bank statements, tax documents, medical records, and pre-approved credit offers. A broken or missing lock means anyone walking by can access that information. Replacing a compromised mailbox lock is one of the cheapest and most effective ways to protect yourself from identity theft. We make it quick and easy.

Housing stock in and around Newport spans several decades, and hardware from every one of those decades still turns up on service calls. We come prepared for that range.

Questions from Newport customers
Do you work with insurance claims?
We provide written records of the work and hardware fitted on Newport jobs, which is generally what insurers ask for. Tell us in advance if you need particular detail.
How far in advance should I book?
Same-day is usually available in Newport for non-urgent work, and urgent calls are prioritized immediately. There's rarely a need to book far ahead.
Will the job be finished in one visit?
Usually, yes. Vans heading to Newport carry the common hardware and tooling, so most jobs complete on the first trip rather than needing a parts run.
How do I know the quote won't change once you arrive?
It won't, as long as the job matches what was described on the phone. If the technician finds something genuinely different in Newport, you'll be told and asked before any extra work happens.
Is there a Kwikey shop in Newport I can visit?
No — we're a mobile service. For mailbox lock replacement, the technician comes to your location in Newport with the equipment on the van. That's usually faster than a shop visit anyway.
Do I need to be present for the work in Newport?
For most jobs yes — we verify authority over the property or vehicle before starting. If that's difficult, call (302) 551-2550 and we'll work out what's practical.
Are your Newport technicians licensed and insured?
Yes, every one of them, and they carry ID you can check before work begins. We'll also tell you the technician's name when we dispatch.

Mailbox Lock Replacement FAQ
These are the questions people ask most before booking this service. If yours isn't here, call us - we'll answer it directly.
Can you open my mailbox if I lost the key?
Yes. We use small bypass tools to open it without damaging the box. Once it's open, we replace the lock and give you new keys so you don't have this problem again.
Do I need to contact the post office first?
Usually no. If it's your personal mailbox or your apartment unit, we can replace the lock directly. The post office only manages the master lock that lets the carrier deliver - we don't touch that.
How long does it take?
About 10-15 minutes once we're on site. Mailbox locks are small and straightforward to replace. The hardest part is usually getting the old corroded one out.
Will I get multiple keys?
Yes. New mailbox locks typically come with 2 keys. If you need extras for family members or tenants, we can cut additional copies on the spot.
My mailbox lock is frozen - can you fix it or does it need replacing?
If it's seized from internal corrosion, replacement is usually the better option. A corroded lock will just freeze again. We install a weather-resistant replacement that handles the elements better.
Can't open your mailbox?
Tell us what type of mailbox you have - curbside, wall-mount, or community cluster unit. We'll confirm availability, bring the right lock, and have your mailbox working with new keys in one visit.
