Every key duplication includes precision cutting using professional-grade equipment. We work with all standard residential key types common in Darby homes, from basic house keys to deadbolt keys.
Darby’s housing stock includes many older homes with unique lock systems. We maintain cutting wheels and techniques for vintage keys that newer shops can’t handle. Your 1920s row house key or mid-century ranch key gets the same expert attention as modern locks.
We use OEM specifications when cutting keys for major lock brands including Kwikset, Schlage, and others. That means your duplicate key fits and operates exactly like the original manufacturer intended. You get reliability that lasts.
Most standard house keys are cut and ready in 2-3 minutes at our Prospect Park location. We keep professional cutting equipment on-site specifically for fast residential service.
Unusual or vintage keys might take 5-10 minutes while we select the right cutting technique. Darby has many older homes with unique key types, and we’ve developed methods for handling these challenging duplications over our 140+ years in business.
You don’t need an appointment for basic key cutting. Just walk in during business hours and we’ll handle your duplication immediately.
We duplicate all standard residential keys including front door keys, back door keys, deadbolt keys, and garage door keys. Our equipment handles both modern and vintage key types commonly found in Darby homes.
This includes challenging keys that other shops turn away – older Yale locks, vintage Schlage keys, and unique key types from Darby’s historic housing stock. We maintain specialized cutting wheels and techniques specifically for these situations.
We also cut keys for patio doors, window locks, and other residential security hardware. If it’s a key for your home, we can likely duplicate it on the spot.
Our precision cutting technology accounts for wear patterns on your original key to produce copies that work as smoothly as new keys. We avoid the “copy of a copy” problems that create poorly functioning duplicates.
Each key gets individually examined before cutting to determine the best approach. We test every duplicate before handing it over to ensure it operates your lock smoothly without sticking or binding.
Our four generations of experience mean we understand how different lock types wear over time. We adjust our cutting technique accordingly so your duplicate key works perfectly with your specific lock’s current condition.
Yes, we provide mobile locksmith services throughout Darby and Delaware County for situations where you can’t get to our shop. This includes emergency key cutting when you’re locked out or need immediate duplicates.
Our mobile units carry key cutting equipment for most standard residential keys. We can come to your Darby location and cut replacement keys on-site, though some specialty keys might require a trip to our fully equipped shop.
Mobile service is particularly helpful when you need multiple keys cut for a new home or apartment, or when you’re dealing with a lockout situation and need immediate access plus spare keys.
Bring the original key you want duplicated – that’s all you need for most residential key cutting. Make sure the original key still works in your lock before coming in, as we use it as the template.
If you have multiple keys for the same lock, bring the one in the best condition. Worn or damaged originals can sometimes produce less accurate copies, though our experience often lets us work around minor wear issues.
For high-security or restricted keys, you might need to show proof of ownership or authorization. We’ll let you know if any additional documentation is required when you arrive.
Standard house key duplication is very affordable – typically just a few dollars per key. We keep our pricing reasonable because we understand Darby families need reliable access without breaking the budget.
Specialty keys or challenging vintage keys might cost slightly more due to the extra time and expertise required. We’ll give you the exact price before starting any work so there are no surprises.
Volume discounts are available if you need multiple keys cut at once – common when moving into a new home or wanting to provide keys to several family members. Just ask about pricing for your specific needs.
