Rekeying means changing the internal pin tumblers inside your existing lock cylinder so that old keys no longer work and a new key is cut to fit. The hardware stays in place. Only the internal configuration changes.
It’s the most cost-effective security upgrade available — and the single most important thing to do when you move into any Dallas home, whether it’s a new build in Frisco, a resale in McKinney, or a condo in Uptown.

When to Rekey vs. Replace Locks
Rekey when: The lock hardware is in good condition, you just need to eliminate old key access, or you’re moving into a new home. This covers 90% of situations.
Replace when: The lock is damaged, worn, or a low-quality builder-grade model below ANSI Grade 1. Or when you want to upgrade to a smart lock or high-security cylinder (Medeco, Mul-T-Lock).
When you call KeyNow Locksmith for residential service, we’ll tell you honestly which situation you’re in — and we won’t upsell you on a replacement if a rekey is all you need.
Frequently Asked Questions
Rekeying a single lock in Dallas typically costs $20–$40 per cylinder plus a service call fee ($35–$65). A full house rekey covering 3–5 locks usually runs $80–$175 total. Rekeying is almost always significantly cheaper than replacing locks entirely. Call (214) 272-2447 for an exact quote based on your number of locks and brand.
Rekeying is almost always the right choice when you move into a new home, unless the existing locks are damaged, worn, or below Grade 1 quality. Rekeying re-pins the cylinders so all previous keys stop working — it costs a fraction of new hardware. If you want to upgrade the lock quality at the same time, we can replace and rekey in the same visit.
A typical Dallas home rekey (3–5 locks) takes 30–45 minutes for a professional locksmith. We carry pins and blank keys for all major lock brands on the truck, so there’s no waiting on parts. Most customers are completely rekeyed before they’ve finished their first box of moving supplies.
