Cheapest Way to Change a Lock: Real Tips from a Regular Guy

Changing a lock doesn’t always mean spending a lot of money or calling a professional every time. I’m just a regular guy—not a native English speaker—but I know how frustrating it feels to overpay for something simple. If you’re looking for the cheapest way to change a lock, let me share what I’ve learned from personal experience and from talking to real locksmiths.
Main Tip: Rekeying Is Cheaper Than Replacing
Here’s the biggest secret: most of the time, you don’t need to buy a brand-new lock. The cheapest way to change a lock is by rekeying it. This means changing the inner pins of the lock so the old keys no longer work, while keeping the same outside hardware. It’s much more affordable—and quicker—than replacing the entire lock.
Why Rekey Instead of Replace?
- Save Money: Rekeying is cheaper because you don’t have to buy a new lock—just a rekeying kit or a small service from a locksmith.
- Keep Your Style: Like how your lock looks? No need to change it.
- Quick and Easy: If you do it yourself, rekeying usually takes just 20–30 minutes.
How to Rekey a Lock Yourself
To save the most money, you can buy a rekeying kit from a hardware store or online. In the U.S., these kits usually cost between $10 and $25 and work for popular brands like Kwikset or Schlage.
Steps to Rekey:
- Buy a rekey kit for your specific lock brand.
- Follow the instructions (the kit usually includes tools and new pins).
- Remove the lock from your door.
- Replace the pins as instructed.
- Reinstall the lock and test it with your new key.
It may sound a bit scary, but if you can use a screwdriver, you can probably handle it. Go slowly, and watch a YouTube video if you need help.
Take Your Lock to a Locksmith Shop
If DIY isn’t your thing, you can simply remove the lock and take it to a local locksmith shop. This is usually cheaper than having a locksmith come to your house. They’ll rekey it for you, and then you can reinstall it yourself.
When Should You Replace the Entire Lock?
There are times when buying a new lock is the better choice:
- The lock is broken, rusty, or very old.
- You want a new look or higher security.
- You lost the key and can’t remove the old lock.
Buying and installing a new lock yourself is still affordable—just make sure the new lock matches your door. Most installations require only a screwdriver and some patience.
Extra Tips to Save Money
- Buy in Bulk: Need to change several locks? Multi-packs are cheaper per lock.
- Stick to One Brand: If all your locks are the same brand, you can rekey them to use the same key—less hassle, less cost.
- Ask for Deals: Sometimes locksmiths or hardware stores offer discounts or seasonal sales.
Should You Call a Locksmith?
If you’re not confident using tools or your lock is complicated, calling a locksmith is a smart move. But always ask for the price before they come out. Some locksmiths charge a lot for house calls. Check reviews and compare prices to avoid surprises.
