Residential Locksmith Services Havertown

Your Home Secure Without the Stress

When your locks work the way they should, you stop thinking about them. That’s the point. You’re not wondering if the previous owner still has a key floating around, or if that side door deadbolt is about to fall apart. You’re not stuck on the porch at 9 PM because your key snapped off in the lock.

You just walk in. Lock the door behind you. Done.

That’s what happens when your locks get rekeyed after you move in, when worn-out hardware gets replaced before it fails, and when a locksmith actually knows what they’re doing. Most people in Havertown don’t think about their locks until something goes wrong. But by then, you’re dealing with a lockout, a break-in scare, or a bill that’s way higher than it should’ve been. We handle residential rekeying, new lock installation, lock repair, deadbolt services, and everything in between so you can skip the panic and get back to your day.

We've Been Doing This for Years

We’ve been serving Havertown and the surrounding Delaware County area for years. We’re not a national franchise or a call center that farms out your job to whoever’s available. We’re local, we know the area, and we know the homes here—plenty of them built in the ’40s with original hardware that’s seen better days.

We show up when we say we will. We quote the price upfront. And we do the work right the first time so you’re not calling someone else to fix what we did. Whether you need your locks rekeyed after buying a house, a deadbolt installed on your back door, or help getting back inside after a lockout, we’ve handled it before and we’ll handle it again.

How Lock Installation Works Havertown

Here's What Happens When You Call

First, you call or message us and tell us what’s going on. Locked out? Need a rekey? Installing new hardware? We’ll ask a few quick questions to understand the situation and give you a clear price estimate over the phone—no surprises later.

Then we schedule a time that works for you, usually same-day or next-day depending on how urgent it is. We show up on time with the tools and parts needed to get the job done. If it’s a lockout, we get you back inside without damaging your door. If it’s a rekey, we change the pins in your existing locks so old keys don’t work anymore. If it’s new lock installation, we remove the old hardware and install the new deadbolts, knobs, or electronic locks you picked out.

The whole process is straightforward. You’re not waiting around for hours or dealing with hidden fees at the end. We finish the work, test everything to make sure it’s working right, hand you your new keys, and you’re all set.

Lock Repair and Rekeying Havertown

What's Actually Included in the Service

Here in Havertown, most homes are older. That means locks that stick, deadbolts that don’t latch right, and hardware that’s been painted over three times. We handle all of it—lock repair for mechanisms that are worn out, rekeying services when you need to control who has access, and full lock replacement when the hardware is too far gone to save.

If you just bought a house, rekeying is usually the smartest move. It’s faster and cheaper than replacing every lock, and it means the previous owner’s keys stop working immediately. You keep your existing hardware, we just change the internal pins so only your new keys work. One key can even open every door in your house if that’s what you want.

For homes with older or damaged locks, new installation makes more sense. We pull out the old stuff and put in fresh deadbolts, door knobs, levers, or even electronic locks if you’re upgrading to keyless entry. Mailbox locks, mortise locks, smart locks—we install and service all of it. And if you’re dealing with a lockout, we get you back in without wrecking your door or charging you double because it’s after 5 PM.

How much does it cost to rekey locks in Havertown?

Rekeying costs less than replacing your locks entirely, and the price depends on how many locks you need rekeyed and what type of hardware you have. Most residential rekeying jobs in Havertown run between $15 to $30 per lock, but we give you an upfront quote before we start any work so there’s no confusion.

If you’re rekeying multiple locks at once—like after buying a house—it’s usually more affordable per lock than doing them one at a time. Standard pin tumbler locks are straightforward to rekey. High-security locks or mortise locks take a bit more time and specialized tools, so those can cost a little more.

The benefit of rekeying is that you keep your existing hardware. We just change the internal pins so your old keys don’t work anymore, and you get new keys that do. It’s fast, it’s effective, and it gives you control over who has access to your home without the expense of buying all new locks.

Rekeying means we keep your existing lock hardware and change the internal pin configuration so old keys no longer work. You get new keys, but the lock itself stays in place. It’s faster and cheaper, and it’s the right call if your locks are in good shape and you just need to reset who has access.

Changing locks means we remove the old hardware completely and install brand new locks. This makes sense if your current locks are broken, outdated, or don’t match the security level you want. It’s also necessary if you’re upgrading to electronic locks or smart locks, or if your existing hardware is a different brand and you want everything to match.

Both options work. It just depends on your situation. If you bought a house and the locks are fine but you don’t want the previous owner’s keys to work, rekey them. If the locks are old, damaged, or you want better security, replace them. We can walk you through what makes sense for your home when you call.

Yes. We install electronic locks, smart locks, and keyless entry systems on homes all over Havertown. These locks let you unlock your door with a code, a phone app, or even a fingerprint instead of fumbling with keys. They’re especially popular with people who want to give temporary access to contractors, dog walkers, or family members without handing out physical keys.

Smart locks come in different styles. Some replace your deadbolt entirely. Others fit over your existing deadbolt so you can still use a key if you want. Most connect to your phone via Bluetooth or Wi-Fi, and some integrate with home security systems or voice assistants like Alexa or Google.

Installation is straightforward, but it’s not always a DIY job. The lock has to fit your door properly, the strike plate has to align, and the electronics need to be set up correctly. We handle the whole process—removing your old lock, installing the new smart lock, programming it, and making sure it works the way it’s supposed to before we leave.

Rekeying a standard house with five or six locks usually takes about 30 to 60 minutes, depending on the type of locks and how accessible they are. If you have more doors or higher-security locks, it might take a little longer. But it’s still faster than replacing all your locks, and you get the same result—old keys stop working and you get new ones.

We bring everything we need to the job. You don’t have to remove the locks or do any prep work. We take each lock off the door, disassemble the cylinder, swap out the pins to match your new key, reassemble it, and reinstall it. Then we test it to make sure it works smoothly.

If you want all your locks keyed alike—meaning one key opens every door—we can do that too. It takes about the same amount of time, and it’s way more convenient than carrying around a keyring full of different keys for your front door, back door, garage, and side entrance.

Yes, we handle home lockouts in Havertown and the surrounding area. If you’re locked out, call us and we’ll get someone out to you as quickly as possible—usually within 30 to 60 minutes depending on where you are and what time of day it is. We don’t charge extra just because it’s an emergency or after hours.

When we arrive, we assess the situation and figure out the best way to get you back inside without damaging your door or lock. Most of the time, we can pick the lock or use specialized tools to unlock it. If the lock is broken or the key snapped off inside, we might need to drill it out and replace it, but we’ll let you know before we do anything.

Lockouts happen. Keys get lost, doors slam shut, locks jam. It’s frustrating, but it’s fixable. We’ve done this hundreds of times, and we know how to handle it without making the problem worse or charging you a fortune for it.

Yes. Even if the previous owners seem trustworthy, you have no idea how many people have keys to that house. Contractors, neighbors, relatives, old tenants—there could be copies floating around that you don’t know about. Rekeying your locks as soon as you move in gives you control and peace of mind.

It’s one of those things people skip because it doesn’t feel urgent, but it’s a simple step that makes your home more secure right away. The cost is low, the process is fast, and you immediately know that you’re the only one with keys that work. No wondering, no risk.

We recommend rekeying within the first week of moving in, before you even finish unpacking. That way it’s done, and you can focus on settling in without worrying about whether someone else might still have access to your house. It’s a small investment that makes a big difference in how safe you feel in your new home.
