Rekey vs. Replace Locks: What Houston and Pearland Homeowners Need to Know

Just moved into a new home? Lost a house key? Going through a situation where someone had access who shouldn’t anymore? These are all cases where you need to change your locks — but you might not need to buy new ones. Here’s how to decide between rekeying and replacing, straight from a licensed locksmith serving Houston and Pearland, TX.

What Does Rekeying a Lock Mean?

Rekeying changes the internal pins inside your existing lock cylinder so that only a new key will work. The hardware stays in place — the only thing changing is the mechanical combination inside. Every old key is immediately rendered useless.

Think of it like changing your Wi-Fi password. Same router, same connection — but anyone with the old password is locked out instantly.

What Does Replacing a Lock Mean?

Lock replacement means removing the entire lock assembly and installing a new one. This is the right call when the hardware is old, damaged, or when you’re upgrading to a higher-security or smart lock option.

When Should You Rekey?

Rekeying is the smarter, more affordable choice when:

• You just moved in — you have no idea who has copies of the previous keys
• You lost a key — rekeying is faster and less expensive than full replacement
• A tenant, roommate, or contractor moved out — cuts off access without replacing working hardware
• You want all your locks on one key — we can rekey multiple locks to match a single key (called keying alike)
• Your lock hardware is in good condition — if it works properly, rekeying saves you significant money

When Should You Replace?

Full lock replacement makes more sense when:

• The lock is damaged or worn — jammed, stiff, or compromised hardware should be replaced
• You want to upgrade your security — older Grade 3 locks should be upgraded to Grade 1 or Grade 2
• You want a smart lock — keypad, fingerprint, or app-controlled locks require full replacement
• There was a break-in attempt — locks and frames compromised during forced entry need new hardware
• The lock brand doesn’t support rekeying — some budget locks have non-serviceable cylinders

Rekeying vs. Replacing: Cost Comparison

Rekeying

• Per lock: $30–$50
• Whole house (up to 5 locks): $125–$200

Lock Replacement

• Standard deadbolt (parts + labor): $95–$160
• Smart lock installation (parts + labor): $105–$195

For a typical move-in — rekeying 3 exterior door locks — you’re looking at $90–$150 total. That’s far less than buying and installing new deadbolts on every door. Unless your locks are old or damaged, rekeying wins on value every time.

Can I Rekey My Own Locks?

DIY rekeying kits exist for popular brands like Kwikset and Schlage. If you’re mechanically inclined, it’s technically possible. However, the process involves disassembling a lock cylinder, rearranging tiny spring-loaded pins in the correct order, and reassembling without losing any pieces. One mistake and you can permanently lock yourself out.

A professional locksmith completes a full rekey in 10–15 minutes per lock. For most households, the whole house is done in under an hour. The labor cost is usually worth it for the peace of mind alone.

What About Smart Locks?

Smart locks — like Schlage Encode, Kwikset SmartCode, or August — are growing in popularity across Houston and Pearland. They allow keypad entry codes, app control, and temporary access codes, making them ideal for homeowners who frequently let in contractors, cleaners, or short-term guests.

Smart locks require full hardware replacement, not rekeying. K&E Locksmith installs and programs all major smart lock brands. We’ll also make sure the lock is properly aligned and functioning before we leave.

How to Know If Your Lock Is Rekey-Ready

Most standard deadbolts and knob locks from major brands — Kwikset, Schlage, Baldwin — can be rekeyed. If your locks are in working condition from a recognizable brand, they’re almost certainly serviceable. Call us before we come out and we can confirm — we won’t dispatch a tech for a job that doesn’t need one.

Frequently Asked Questions

Can you rekey all my locks to use one key?

Yes. This is called keying alike, and it’s one of the most popular services we offer for homeowners. We rekey every exterior lock so a single key opens them all.

How long does rekeying take?

Most full-house jobs are done in 30–60 minutes. We come to you — no need to remove locks or visit a shop.

Does rekeying void my lock’s warranty?

Generally not when performed by a licensed locksmith. Most major manufacturers explicitly allow professional rekeying. Check your lock’s specific warranty terms if this is a concern.

Can you rekey a lock without the original key?

Yes, but it requires picking or drilling the lock cylinder first, which adds a small amount to the service cost. Always let us know upfront so we can give you an accurate quote.
