What We Do
Here is a detailed look at every residential locksmith service we provide to homeowners and renters throughout Delaware. Not sure what you need? Just give us a call and we'll point you in the right direction.
Being locked out of your own home is one of the most stressful situations you can find yourself in — especially late at night, in bad weather, or with young children waiting outside with you. It happens more often than most people think, and when it does, you need a residential locksmith who can get there quickly and get you back inside without any damage.
1st Capital Locksmith responds to house lockouts throughout Delaware. Our locksmiths use professional non-destructive entry techniques that open your door without harming the lock, the door frame, or the surrounding trim. We work on all types of residential locks including standard knob locks, deadbolts, lever handles, and keypad entry systems.
Whether you're locked out of your front door, a back door, a bedroom, or a bathroom, we can help. Give us a call and we'll get to you as quickly as possible so you can get back inside and get on with your day.
Moving into a new home is exciting, but here's something many people don't think about right away — you have no idea how many copies of your new house keys are floating around out there. Previous owners, old tenants, contractors, real estate agents — any one of them could still have a working key to your front door. Rekeying your locks the moment you move in is one of the smartest and most affordable things you can do for your family's security.
Rekeying changes the internal pin configuration of your existing lock so that all previous keys stop working and only your new keys will open the door. It's faster and less expensive than replacing the entire lock, and in most cases the result is just as secure. 1st Capital Locksmith performs residential rekeying throughout Delaware, on-site at your home.
Beyond new home move-ins, we also recommend rekeying when keys go missing, after a roommate moves out, or after any situation where you're uncertain about who might have access to your home. It's a small investment that pays for itself in peace of mind.
If your exterior doors only have a basic knob lock or an older deadbolt, your home's security may not be as strong as you think. A quality deadbolt is one of the most effective deterrents against forced entry — and the difference between a standard deadbolt and a properly installed high-security deadbolt is significant.
1st Capital Locksmith installs and upgrades deadbolts for homes throughout Delaware. We carry quality residential deadbolts from trusted brands and can recommend the right option based on your door type, your security concerns, and your budget. We also make sure the installation is done correctly — a poorly installed deadbolt provides far less protection than one that's properly set and aligned.
Whether you need a new deadbolt added to a door that doesn't have one, or you want to replace an older lock with something more robust, we handle the entire job on-site. We also install double-cylinder deadbolts, keypad deadbolts, and smart lock deadbolts depending on your preference.
Locks don't always fail all at once — they usually give you warning signs first. A key that's getting harder to turn, a deadbolt that doesn't fully extend, a knob that feels loose or rattles in the door — these are all signs that your lock needs attention before it becomes a real problem. A lock that's struggling is a lock that could fail at the worst possible moment.
1st Capital Locksmith diagnoses and repairs residential locks throughout Delaware. In many cases a lock can be repaired quickly and affordably on-site, saving you the cost of a full replacement. Our locksmiths take the time to properly assess what's going on before recommending a solution, so you only pay for what you actually need.
If your lock was damaged during a break-in attempt, exposed to weather damage, or has simply worn down from years of use, call us and we'll get it working properly again. A well-maintained lock is a reliable lock.
Sometimes a lock is simply past the point of repair — the hardware is too worn, too damaged, or too outdated to provide reliable security. Other times, homeowners want to upgrade to a better quality lock altogether. Either way, 1st Capital Locksmith makes residential lock replacement straightforward and hassle-free throughout Delaware.
We carry a selection of quality residential lock hardware and can replace any lock in your home on the same visit. Whether it's your front door, back door, garage entry door, or interior room locks, we handle it all on-site. We also make sure the new lock is properly fitted to your door for smooth, reliable operation.
If you're not sure whether your lock needs repair or replacement, just call us. We'll take an honest look and give you a straightforward recommendation — no unnecessary upselling.
Your mailbox contains more sensitive information than most people realize — bank statements, credit card offers, medical documents, and personal correspondence all pass through it regularly. A broken or compromised mailbox lock puts all of that at risk. If your mailbox key is lost, your lock is damaged, or you've moved into a new place and aren't sure who has the key, getting the lock replaced is a smart and simple security step.
1st Capital Locksmith replaces mailbox locks for homeowners and apartment residents throughout Delaware. We work on standard residential mailboxes, cluster mailbox units, wall-mounted boxes, and post-mounted units. It's a quick service that we handle on-site, and we provide new keys on the spot.
Don't overlook your mailbox security. It's a small lock, but what it protects can have a big impact on your personal and financial privacy. Call us to get it sorted quickly and affordably.

"Just moved into a new house and wanted all the locks rekeyed before we got settled in. 1st Capital Locksmith came out the same week, rekeyed every exterior door, and gave us new keys on the spot. Fast, friendly, and very reasonably priced. Highly recommend them to anyone moving into a new home in Delaware."

Lock Rekeying — Smyrna, DE
"Our front door deadbolt was getting harder to turn every week. I kept putting off calling someone but eventually it got stuck completely. 1st Capital Locksmith came out, diagnosed the problem, and replaced the whole lock with a quality deadbolt the same day. Works like a dream now. Wish I had called sooner."
