Lock Rekeying Cost: What Affects Your Quote

Lock Rekeying Cost

Lock rekeying replaces the internal pins in a lock cylinder so old keys no longer work, without replacing the entire lock hardware. Because it uses the existing lock body, it’s typically positioned as a lower-cost alternative to full lock replacement — but the final price depends on several variables specific to your locks and situation.

Alpine Mobile Locksmith is an informational referral resource. We don’t perform locksmith work directly or set provider pricing; the information below is meant to help you understand what shapes a rekeying quote so you can evaluate estimates from independent providers with confidence.

What Determines a Rekeying Quote

Number of locks. The number of cylinders or locks can affect the scope of a rekeying quote. Providers may structure pricing differently, so confirm whether the quote is per cylinder, per lock, per visit, or another method.

Lock brand and hardware type. Standard residential deadbolts and knob locks are generally the most straightforward to rekey. High-security lock brands, smart locks, or less common hardware may require specialized parts or additional labor, which can affect the quote.

Matching locks to one key. If your locks are different brands or models, a technician may need to source compatible pins or hardware to key them all alike. This can take more time than rekeying locks that already share a keyway.

Lock condition. Older, worn, corroded, or damaged cylinders sometimes need additional parts or labor beyond a standard rekey, and in some cases a technician may recommend replacement instead if the hardware can’t be reliably serviced.

Service call context. Timing, location, and travel may affect a quote depending on the provider. Ask whether the requested appointment time or service location changes the quoted total.

Number of keys provided afterward. The number of keys supplied with rekeying varies by provider and quote. Confirm how many keys, if any, are included and the price for additional copies.

What May Be Included in a Quote

Depending on the lock hardware and provider, a rekeying quote may include:

• Removal and disassembly of the lock cylinder
• Replacement of internal pins to match a new key
• Reassembly and functional testing of the lock
• A set number of new working keys

Items to Confirm in the Quote

Depending on the provider and situation, these are sometimes billed separately rather than bundled into a base rekeying price:

• Replacement parts for damaged or worn cylinders
• Extra keys beyond the included set
• Rekeying smart locks or electronic hardware
• Mobile service or trip charges, particularly for after-hours calls
• Rekeying locks of mismatched or uncommon brands

Not every provider charges for all of these, and some bundle certain items into a flat rate — it’s worth asking directly rather than assuming.

Rekeying vs. Lock Replacement

Rekeying is generally worth pricing out when your existing locks are in good working condition and you simply need old keys deactivated — for example, after moving into a new home, following a lost key, or after a roommate or tenant change. If your locks are damaged, outdated, or you want to upgrade to different hardware or a smart lock system, full replacement may be the more relevant comparison, and pricing works differently for that scope of work.

Questions to Ask Before Booking

• Is the quote per lock or a flat rate for all locks at this address?
• How many keys are included, and what does an extra key cost?
• Does the quote change if a lock is worn, damaged, or a different brand than the others?
• Is there a separate service call or mobile dispatch fee?
• Does the price differ for evening, weekend, or emergency requests?
• Is the estimate confirmed after the technician inspects the hardware in person?

Getting these answers upfront makes it easier to compare quotes from different providers on equal terms.

When You Need a Different Guide

If you’re locked out right now and need entry rather than a rekey, see the House Lockout Cost Guide or the Car Lockout Cost Guide. If you’ve lost a vehicle key or need a replacement key cut and programmed, the Car Key Replacement Cost Guide covers that pricing separately. For office, retail, or multi-door commercial properties, see the Commercial Locksmith Cost Guide. If your rekeying need is tied to an urgent, after-hours situation, the Emergency Locksmith Cost Guide explains how urgency and timing may affect a provider’s quote.

Next Step

To get an accurate rekeying quote, contact a locksmith provider with details on the number of locks, their brands, and their condition — this gives the most reliable estimate before a technician arrives.
