Warning Signs

When You Need Duplicate House Keys in St Charles

Most folks call us after they've lost a key or handed their last one to a roommate. Others want spares for a sitter or a family member before winter hits. Old brick homes in Frenchtown often still use original mortise locks. A worn key can slip or stick as the lock wears down. Newer builds in New Town or Beau Chateau use standard cylinders. They're quick to copy but cheap cylinders wear out faster than you'd think. Clay soil around St Charles shifts foundations over time. This can throw off door alignment and make a key harder to turn. Locks and keys have worked the same basic way for centuries. Small wear adds up fast.[1] Don't wait until you're stuck outside in the cold with no spare.

2

We Cut and Match

Every duplicate gets tried in your lock before you leave. If it doesn't turn smooth, we fix it right there.

Fair Pricing

Duplicate House Keys Cost in St Charles

Price depends on the type of key you need. A basic house key costs less than a high-security or antique skeleton key. Historic homes in Frenchtown with original mortise hardware take more time and care, so those run a bit higher. We give you the price upfront before we cut anything, and seniors and military get a discount. Locks and keys haven't changed much in basic design for generations, but matching an old cut takes real skill.[1]

✓ You get a clear price quote before any cutting starts.
✓ No hidden fees added once the work is done.
✓ Senior and military discounts applied on request.
Typical price range
$8 - $45
Standard keys cost less than high-security or restricted keyways.
Antique or skeleton keys take more time to match correctly.
Multiple copies at once usually lower the per-key price.
On-site visits to your home may add a small trip fee.

I had a great experience at ASAP Lock & Key! Collin was incredibly friendly and helpful. He helped me replace the shell on my car key, cut it for me, and even walked outside with me to make sure everything worked properly before I left.

I really appreciated the extra effort and attention to detail. He could have simply handed me the key and sent me on my way, but he took the time to make sure everything was working and that I was taken care of. That kind of customer service really stands out. Thank you, Collin, for the great service!

I have used this company twice. Once to get a key cut for a CanAm Spyder the second time to get a round key made for a small trailer you pull behind a motorcycle. Both times the staff went over and above to take care of me. Both times they were slightly unusual situations. Excellent customer service and reasonable prices. I will be using this company every time I need locksmith services, even though there are closer ones to my house. Thanks guys!

I locked myself out of our new house this morning and after talking with questionable mobile service locksmiths, I found ASAP and called and was very happy that someone could come right out to get me in. He was friendly and professional! We bought the house without any keys so he offered to re-key the doors for us, which was exactly what we needed! I would highly recommend them! You can trust them!

Outstanding experience. My son locked his keys in his golf bag and hustled over and helped out within 15 minutes. They were extremely helpful and reasonably priced. I highly recommend them.

Key Questions

Duplicate House Keys Questions

Here are answers to what St Charles homeowners ask us most.

  • How much does a duplicate house key cost?

    Most standard duplicate keys run between $8 and $20. High-security or antique keys cost more because they take extra skill to match. We'll always tell you the price before we start cutting.

  • How long does it take to make a copy?

    Most duplicate keys take just a few minutes to cut and test. Antique or high-security keys can take a little longer. We won't rush the job if it needs extra care.

  • Can I just use a hardware store kiosk instead?

    You can, but we've seen plenty of kiosk copies that don't turn right. A bad cut can wear down your lock over time. We test every key by hand before you leave.

  • How many spare keys should I have?

    We usually suggest two or three spares per household. One for a trusted neighbor, one for family, and one tucked away safely. It beats scrambling during a lockout.

  • What if I lost my only key?

    No problem, we can cut a fresh key straight from your lock. It takes a little longer than copying a key, but it's a quick fix. Just give us a call and we'll get you back inside.

  • How do I know if my key is wearing out?

    Look for rounded edges, a loose fit, or a key that sticks when turning. These are signs it's time for a fresh cut. Worn keys can also wear down your lock faster.

  • Can you duplicate old skeleton or mortise keys?

    Yes, we handle antique skeleton and mortise keys often in the Frenchtown area. These need careful hand matching since the originals vary so much. We take the extra time to get them right.
