How Much Does It Cost to Rekey a Residential Front Door?
Whether you just moved into a new home in Encinitas, lost a set of keys, or ended a lease with a tenant, rekeying your front door is one of the smartest and most affordable security upgrades you can make. But how much should you actually expect to pay? The answer depends on a few key factors, including your lock type, the number of doors, and whether you hire a mobile locksmith or visit a shop. In this guide, we break down real 2026 pricing so you can budget confidently before picking up the phone.
What Is Rekeying and How Does It Work?
Rekeying is the process of changing the internal pins inside your lock cylinder so that a new key operates the lock while all old keys stop working. Your existing hardware, including the deadbolt, handle set, and finish, stays in place. Only the internal pin configuration changes.
A professional locksmith removes the cylinder from the lock body, swaps out the existing pins for new ones that match a freshly cut key, and reinstalls the cylinder. The entire process typically takes 15 to 30 minutes per door for a skilled technician. It is a non-destructive service, meaning lock appearance, function, and warranty remain unaffected.
Average Cost to Rekey a Front Door in 2026
If you are rekeying a single front door with a standard pin tumbler deadbolt and knob, expect to pay between $100 and $250 total when a locksmith comes to your home. That price typically includes a service call fee, the rekey labor, and two new keys.
| Service | Typical Cost Range (2026) |
|---|---|
| Service call / trip fee | $50 - $100 |
| Rekey per standard lock cylinder | $15 - $50 |
| Front door rekey (deadbolt + knob, on-site) | $100 - $250 |
| Each additional door (same visit) | $45 - $65 |
| High-security cylinder rekey | $30 - $75 per cylinder |
| Extra key copies | $3 - $8 each |
| Emergency / after-hours surcharge | $25 - $95+ |
These ranges align with Homewyse's 2026 national estimates of $100 to $233 per lock. Bundling multiple doors into one visit is the fastest way to lower your per-door cost, since the service call fee is only charged once.
Factors That Affect Rekey Pricing

Lock Type and Brand
Standard Kwikset and Schlage locks are the most affordable to rekey. Premium brands like ASSA or Medeco use restricted keyways and patented mechanisms, which increases labor time and parts cost. If you are unsure what brand you have, a residential locksmith can identify it on arrival.
Number of Cylinders
A cylinder is where a key enters the lock. Some doors have two cylinders (a key on each side), while others have a thumb turn on the interior and only one keyed cylinder. Rekeying is priced per cylinder, not per lock, so count your keyholes for a more accurate estimate.
Time of Service
Business-hours appointments (Monday through Friday, 8 AM to 6 PM) offer the best rates. After-hours, weekend, and holiday calls often carry a surcharge of $25 to $95 or more. Scheduling your rekey during normal hours is one of the simplest ways to save money.
Rekey vs. Replace: Which Saves You More?
Rekeying is almost always cheaper than a full lock replacement. According to Yelp's cost data, the average cost to rekey a lock is around $140, while replacing a lock and paying for new hardware plus installation can run approximately $400. Rekeying is typically 40 to 60 percent cheaper than replacing locks entirely.
Replacement makes more sense only when existing hardware is visibly worn, damaged, or more than ten years old. If your current locks are in solid working condition, rekeying delivers the same security benefit at a fraction of the price. For homes that need new hardware, our lock repair and installation page covers those options.
When Should You Rekey Your Locks?
There are several situations where rekeying is the right call:
- Moving into a new home. You have no way of knowing how many copies of the old keys exist.
- After a tenant moves out. Landlords should rekey between tenants as a standard security practice.
- Lost or stolen keys. If a lost key could reveal your address, rekeying removes the risk.
- After a break-in or attempted break-in. Restoring secure access should happen immediately.
- Consolidating keys. If you currently juggle different keys for the front door, back door, and garage entry, rekeying lets one key work every lock. All locks must be from the same manufacturer (Kwikset, Schlage, or Yale) to be keyed alike.
