You get keys that actually work when you need them most. No more standing at your front door with a key that won’t turn, no more emergency locksmith calls because your “backup” key snapped in half.
When we cut your keys, they’re cut right the first time using factory OEM blanks and precision equipment. That means smooth operation, proper fit, and keys that last as long as your originals.
You’ll have reliable backup access to your home, spare keys for family members, and the peace of mind that comes from working with locksmiths who’ve been perfecting their craft for over a century.
Our family has been cutting keys since the late 1800s. What started with Charles McCausland Senior has grown into the largest locksmith company serving the Delaware Valley, now run by fourth-generation locksmiths Chuck and Tom McCausland.
That’s over 100 years of locksmithing knowledge passed down through our family. While other companies come and go, McCausland Lock Service has been here for Thornton residents through every decade, every home renovation, every family milestone that required new keys.
You’re not just getting a key copied. You’re getting the expertise that comes from a family who’s seen every type of lock, every brand of key blank, and every challenge that can come up in residential locksmithing.
Bring your original key to our shop in nearby Prospect Park, or we can come to you. We examine your key to determine the correct blank and cutting specifications needed for your specific lock manufacturer.
Using precision key-cutting equipment, we duplicate your key to exact factory specifications. This isn’t a quick hardware store copy job – we take the time to ensure proper depth, spacing, and smooth edges that won’t damage your locks.
We test every key before you leave to make sure it works smoothly in your lock. If there’s any issue, we’ll recut it on the spot. You walk away with keys that work perfectly, backed by our family’s reputation for quality.

We handle all types of residential keys – from standard house keys to high-security deadbolt keys, decorative keys, and specialty hardware. Unlike big box stores that only carry common blanks, we stock thousands of key blanks for every major lock manufacturer.
For Thornton homeowners, this means we can duplicate keys for older homes with vintage hardware, newer construction with modern security systems, and everything in between. We also handle keys marked “Do Not Duplicate” when you provide proper authorization.
Our service includes key cutting for front doors, back doors, side entrances, mailboxes, and any other residential locks you need duplicated. Each key is cut with the same attention to detail, whether you need one spare or a dozen copies for family members.
Basic residential key duplication typically costs $2 to $5 per key at our shop. High-security or specialty keys range from $8 to $25 depending on the complexity and security features involved.
The exact cost depends on your key type and the blank required. Standard house keys for major brands like Schlage or Kwikset are on the lower end, while restricted or high-security keys require special blanks and authorization. We provide upfront pricing before any work begins, so you know exactly what you’re paying.
Most standard residential keys take just a few minutes to duplicate. We can typically cut and test your key while you wait, making it one of the fastest services we offer.
High-security keys or specialty hardware may take 10-15 minutes if we need to verify specifications or locate the correct blank from our inventory. We stock thousands of blanks, but occasionally need to order specific types for unusual locks. In those cases, we’ll let you know the timeline upfront.
Yes, we can duplicate “Do Not Duplicate” keys when you provide proper authorization. These keys are typically used for high-security residential locks and require verification that you’re the authorized key holder.
You’ll need to show proof of ownership or authorization, such as documentation from your lock manufacturer or property management company. We follow all legal requirements for restricted key duplication while ensuring you get the copies you need for your home security.
We use precision equipment and have access to thousands of key blanks that hardware stores don’t carry. We can duplicate keys for older locks, specialty hardware, and high-security systems that automated kiosks can’t handle.
More importantly, we test every key before you leave and guarantee it works properly. Hardware store machines often produce keys that don’t fit correctly, especially if your original key is worn or if the machine isn’t properly calibrated. When you need keys that work the first time, professional duplication is worth the small price difference.
Yes, we provide mobile locksmith services throughout the Thornton area when needed. Our fully equipped service vehicles can handle key duplication on-site, along with other locksmith services you might need.
Mobile service is particularly useful if you’re locked out and need immediate key duplication, or if you have multiple locks that need attention. We charge a reasonable service call fee for mobile visits, and we can often handle several services during one trip to maximize your value.
Yes, we can create new keys even without the original through lock impressioning or by using your lock’s code. This process takes longer than standard duplication but is often necessary when keys are lost or stolen.
We can take an impression of your lock cylinder to create a working key, or if you have the lock code from your manufacturer, we can cut keys based on those specifications. This service typically costs more than standard duplication due to the additional time and expertise required, but it gets you back into your home when other options aren’t available.
