Q: Do locksmiths charge a trip fee for rekeying?

Many charge $50,$100 for the service call, then a per-lock rate. Reputable mobile locksmiths like Half Off Locksmith provide flat-rate quotes up front with no hidden fees.

What Does Rekeying Mean?

Rekeying replaces the internal pin-tumbler configuration inside your lock cylinder so old keys no longer work. The locksmith removes the cylinder, swaps out the pins, and cuts new keys to match. The original hardware, knob, deadbolt, strike plate, stays in place.

You keep the same lock but invalidate every old key in circulation. It's faster and cheaper than buying new locksets, especially when you move into a house and don't know who has copies of the previous owner's keys.

Most residential locks use pin-tumbler or wafer mechanisms. Both can be rekeyed as long as the cylinder is removable and in good working order. High-security restricted-keyway locks cost more because pins and blanks are proprietary.

Average Rekey Cost Per Lock

Expect to pay $15, $25 per lock for standard pin-tumbler deadbolts and entry knobs. High-security cylinders, Medeco, Mul-T-Lock, or ASSA ABLOY, run $30, $50 per lock because they require specialized pins and restricted blanks.

Many locksmiths charge a baseline service-call or trip fee, often $50, $100, then a per-lock rate. If you rekey six locks, you might pay $75 trip + ($20 × 6) = $195 total. Always ask for a flat-rate quote before the technician rolls. Half Off Locksmith provides up-front pricing with no hidden trip fees, so you know the total cost before we dispatch.

Additional factors that affect price:

Time of day: After-hours or emergency calls may carry a premium, though some mobile services include in their standard rate.
Lock condition: Corroded, jammed, or damaged cylinders may need extra labor or replacement parts.
Keying configuration: Keying all locks to one master key adds complexity and a small upcharge.
Smart locks: Electronic deadbolts with mechanical backup cylinders can be rekeyed, but programming digital credentials is a separate step.

Whole-House Rekey: What to Expect

A typical single-family home has 4 to 8 exterior door locks, front, back, garage entry, side gate, plus sometimes interior bedroom or office locks. Budget $150, $400 for a complete residential rekey, depending on lock count and type.

The process takes 30 to 90 minutes for an experienced locksmith. Pin-tumbler deadbolts rekey in under ten minutes each. High-security or older mortise locks take longer. The technician will pull each cylinder, measure the existing keyway, select new pins, reassemble, test the action, and cut keys on the spot.

You'll receive a set of new keys, usually two to four per lock or one master key that operates all cylinders if you choose master keying. Label spares and keep one in a secure off-site location.

Rekey vs. Replace: Which Costs Less?

Rekeying is almost always cheaper when your existing hardware is functional. A mid-grade ANSI Grade 2 deadbolt costs $30, $60 retail, plus $50, $100 for professional installation. Rekeying that same lock runs $15, $25 with no hardware expense.

Replace locks if:

The cylinder is damaged, worn, or jams frequently.
You want to upgrade security, moving from a Grade 3 builder-grade lock to a Grade 1 commercial deadbolt, adding a longer throw bolt, or reinforcing the strike plate.
You're switching lock styles (knob to lever, standard to smart lock) or finishes for aesthetic reasons.
The keyway is obsolete and blanks are hard to source.

Rekey if the hardware is in good shape and you simply need to control key access. Many homeowners rekey after a move, a breakup, or losing track of spare keys. For more on when to upgrade versus rekey, visit our blog for related guides.

Master Keying and Multi-Lock Discounts

Master keying configures multiple locks so each has its own change key, but one master key opens them all. It's popular for landlords, small offices, or families who want one key for exterior doors and separate keys for bedrooms.

Setup adds about $5, $15 per lock because the locksmith installs additional master pins inside each cylinder. The result is two working key cuts per lock, your individual key and the master. Security trade-off: if the master key is lost or copied, it compromises every lock in the system.

Many mobile locksmiths discount per-lock pricing when you rekey four or more cylinders in one visit. Ask about volume rates and whether a service call is waived above a certain lock count. Bundling all your doors into a single appointment saves time and money.

How to Save on Rekeying Costs

First, get a firm quote before scheduling. Reputable locksmiths offer flat-rate pricing over the phone once you describe lock types and quantities. Avoid companies that refuse to quote until arrival, surprise trip fees and inflated per-lock rates often follow.

Second, rekey all locks in one visit. Trip fees and minimum charges disappear when spread across six locks instead of one. If you only need the front door today, wait and batch it with the back and garage when you're ready.

Third, confirm the locksmith is trained, bonded, and insured. unverified operators may quote low then upsell aggressively or damage your hardware, costing more to fix. Half Off Locksmith is fully trained and insured, and our tagline, Upfront pricing. Real technicians., means you get competitive rates without sacrificing quality or transparency.

Finally, ask if you can supply your own locks for rekeying. Some locksmiths allow it and waive hardware markup, though labor rates stay the same. For additional locksmith services and pricing details, check our services page.

When to Call a Locksmith Instead of DIY

Rekeying requires pin-tumbler knowledge, a pinning kit, key blanks, and a plug follower. Kits cost $30, $100, but mastering the technique takes practice. One mistake, dropping a spring, using the wrong pin size, binding the cylinder, can jam the lock or leave you locked out.

DIY makes sense if you already own the tools, enjoy hands-on projects, and have spare time. For most homeowners moving into a new house or managing an emergency lockout, a professional mobile locksmith is faster and less risky. The cost difference between DIY parts and professional labor is often under $50 when you factor in your time and the risk of errors.

Emergency scenarios, lost keys, broken cylinder, or a lock that won't turn, are always best handled by a trained technician. Trying to force a jammed lock can damage the bolt, door frame, or strike plate, multiplying repair costs. If you're locked out or need same-day service, reach out via our contact page or call directly for mobile dispatch.
