Whether you’re moving into a new home, upgrading your business security, or dealing with a lost key, you’re probably wondering: is it cheaper to rekey or replace locks? The short answer? Rekeying is almost always the more affordable option—but there are important factors to consider before making the final call.
At TN Premier Locksmith, we help homeowners and business owners across Tennessee choose the right option for their security needs without overspending. Let’s break it all down.
Before we get into pricing, here’s a quick breakdown:
Rekeying means keeping your existing lock hardware but changing the internal pins so that old keys no longer work. A new set of keys will be cut to match the new pin layout.
Replacing involves removing the entire lock mechanism and installing a brand-new one.
In both cases, your old keys won’t work—but the cost, time, and hardware involved are very different.
Yes—rekeying is generally much cheaper than replacing locks. On average:
Rekeying a lock costs between $20–$50 per lock, depending on the type of lock and whether it’s done at your home or business.
Replacing a lock can range from $60–$200 per lock, especially if you’re upgrading to high-security or smart locks.
If you’re dealing with multiple locks and want them all to work with one key, rekeying them to match is a highly cost-effective solution.
Rekeying is ideal for situations like:
Moving into a new home
Lost or stolen keys
A roommate or tenant moves out
You want all locks to use a single key
You need a quick and budget-friendly security upgrade
At TN Premier Locksmith, we can rekey your locks on-site, often in under an hour. It’s fast, secure, and budget-friendly.
While rekeying is cheaper, there are times when replacing your locks is the smarter move:
Your locks are old, rusted, or damaged
You want to upgrade to smart locks or keypad entry
You need better home or business security
Your current locks aren’t compatible with rekeying
We offer a wide selection of lock hardware—from standard deadbolts to high-security and keyless entry systems—and can help you choose the right fit.
Trying to rekey or replace locks yourself may seem like a good idea—but it can get complicated fast. If done incorrectly, you risk damaging the lock or creating security vulnerabilities.
