What Does a Locksmith Do? A Complete Guide

“Locksmith” is one of those job titles everyone recognizes but few people can actually define — until they’re standing outside a locked car at 11pm. Here’s what locksmiths do, the different types, and what’s actually outside their scope.

What is a locksmith?

A locksmith is a licensed tradesperson trained to install, repair, bypass, and rebuild locks and security hardware. The trade goes back centuries (literally — cutting keys by hand for physical locks), but the modern version does a lot more than that: transponder key programming, key fob pairing, electronic access control, and safe servicing are all standard parts of the job now.

Most US states require locksmiths to hold a license, pass a background check, and carry liability insurance — because the job inherently involves bypassing security systems, trust matters.

What does a locksmith do, exactly?

Day to day, a locksmith’s work falls into a few core categories:

• Lockouts — opening a locked car, house, or office door without damaging the lock, using picks, bypass tools, or (rarely, as a last resort) drilling.
• Key cutting and duplication — cutting a new physical key from a blank, matched to your existing lock or vehicle.
• Transponder and fob programming — pairing a new car key or remote fob to your vehicle’s immobilizer using OBD-II tools, so the car actually recognizes it.
• Lock rekeying — changing the internal pins of an existing lock so old keys stop working, without replacing the whole lock. Common after moving into a new place.
• Lock installation and repair — installing new deadbolts, smart locks, or door hardware, and fixing locks that are jammed, worn, or damaged.
• Ignition repair — fixing a car ignition that won’t turn or accept a key.
• Commercial security — master key systems, panic bars, access control, and high-security commercial locks for offices and retail.

Types of locksmiths

Locksmiths tend to specialize, and it’s worth knowing which type you need before you call:

| Type | What they focus on | |---|---| | Automotive locksmith | Car lockouts, key cutting, transponder/fob programming, ignition repair | | Residential locksmith | House lockouts, rekeying, lock installation, smart locks | | Commercial locksmith | Master key systems, access control, high-security commercial hardware | | Mobile/emergency locksmith | Comes to your location for any of the above, usually 24/7 |

A mobile locksmith isn’t a separate specialty so much as a delivery model — most automotive and residential locksmiths today operate mobile, driving to you instead of running a storefront.

What locksmiths can’t (or won’t) do

A few boundaries worth knowing:

• They’ll ask for ID. A legitimate locksmith verifies you own the property or vehicle before doing lockout work — usually a photo ID or utility bill matching the address, or vehicle registration for a car. This protects you, not just them.
• They generally don’t bypass high-security or proprietary systems without manufacturer coordination. Some luxury vehicles and commercial access-control systems require dealer or manufacturer involvement for certain codes.
• Drilling is a last resort, not a default. If a locksmith wants to drill your lock immediately without attempting non-destructive entry first, that’s a red flag — see our guide to locksmith scams.
• They’re not a general handyman. Locksmiths handle locks, keys, and related security hardware — not general door repair, plumbing, or electrical work, even though the trades sometimes overlap on job sites.

How much do locksmiths charge?

Pricing depends heavily on the job:

| Service | Typical cost | |---|---| | Car or house lockout | $65–$95 | | Transponder key cut + programmed | $120–$250 | | Key fob replacement | $80–$200 | | Lock rekey (per lock) | $60–$120 | | Ignition repair | $150–$350 |

When should you call a locksmith?

• You’re locked out of your car or home
• You’ve lost your only set of keys
• Your key fob stopped working or needs programming
• You just moved and want your locks rekeyed
• Your ignition won’t turn or accept the key
• You need a business rekeyed or fitted with a master key system

How to find a locksmith you can trust

The trade has a reputation problem — some directories list “local” locksmiths that are actually out-of-state call centers who dispatch whoever’s cheapest and quote a low price, then inflate it on-site. Checking for a license number, upfront pricing, and real reviews before you commit avoids most of that. On LockNear, every locksmith shows their rating, licensing status, and price before you confirm — no surprise call-out fees.
