A locksmith is a trained tradesperson who installs, repairs, and opens locks for homes, businesses, and cars. Locksmiths cut keys, rekey locks, handle lockouts, fix broken locks, and set up smart locks and access systems. To hire a good one, find a local locksmith before you need one, check their license and insurance, and get a clear price before any work starts.
Most of us only think about locksmiths when something goes wrong, like a lost key or a car door that won’t open. But these pros can do far more than that. Here’s what they do, what it usually involves, and how to avoid the scams that target people in a hurry.
What Does a Locksmith Do?
Their main job is to keep locks and security hardware working. Typical tasks include:
- Cutting spare keys
- Rekeying locks so old keys stop working
- Installing new locks and deadbolts
- Repairing jammed or broken locks
- Opening locks without causing extra damage
- Pulling out keys that snapped inside a lock
Many learn the trade through apprenticeships or training programs rather than a college degree. Some U.S. states require locksmiths to hold a license, so check the rules where you live. You can read more about the trade’s long history in this overview of locksmithing.
Types of Locksmith Services
| Type | What they handle |
|---|---|
| Residential | Home lockouts, rekeying after a move, deadbolts, smart locks |
| Commercial | Master key systems, keypads, access control, safes |
| Automotive | Car lockouts, key fobs, transponder keys, ignition repair |
| Emergency | 24-hour lockouts and urgent repairs after a break-in |
Not every company offers every service. So if you need car key programming or a safe opened, ask before you book.
Rekey or Replace? A Common Question
When you move into a new home or lose your keys, you don’t always need new locks. Rekeying changes the inside of the lock so a new key works and old keys don’t. It’s usually cheaper than replacing the whole lock.
Replacement makes more sense if the lock is worn out, damaged, or too weak. It’s also the way to go if you want to upgrade to a stronger deadbolt or a smart lock.
How to Choose a Trustworthy Locksmith
The Federal Trade Commission has warned consumers to be careful when choosing a locksmith. It points out that some companies advertising as “local” aren’t actually local, and some may not have professional training. Its top tip is simple: research a locksmith before you need one, then save the number in your phone.
Use this checklist:
- Confirm they’re truly local. Look for a real street address, not just a phone number.
- Check credentials. Ask for a license (where your state requires one) and proof of insurance.
- Read independent reviews. Use trusted review sites, not only the company’s own website.
- Get a quote upfront. Ask for the total, including call-out fees, before work begins.
- Ask for ID when they arrive. A professional should also ask you for proof that you live there.
Red flags to watch for
- A very low phone quote that jumps once the work starts
- An unmarked vehicle and no company ID
- Pressure to drill and replace a lock right away for a simple lockout
- A business that answers the phone with a generic phrase like “locksmith services”
- Requests for cash only, with no written invoice
A skilled pro can open most standard home locks without drilling. If someone insists on drilling right away, it’s fair to ask why.
How to Avoid a Lockout in the First Place
- Leave a spare key with a trusted neighbor or family member.
- Consider a keypad or smart lock, so you’re not relying on a physical key.
- Keep a spare car key somewhere safe, not inside the car.
- Fix sticky locks early, before they fail completely.

Frequently Asked Questions
What is the difference between rekeying and changing a lock?
Rekeying changes the inner parts of your existing lock so a new key works and old keys don’t. Changing a lock means removing it and installing a new one. Rekeying is usually cheaper and works well after a move. Replacing makes sense if the lock is damaged, worn out, or you want an upgrade.
Can a locksmith open a car?
Yes. Automotive locksmiths can open most cars without damage, and many can cut or program replacement keys and fobs. Some newer cars need special equipment, so ask whether the locksmith works with your make and model. It’s also worth checking whether your car insurance or roadside plan covers lockouts.
How do I know if a locksmith is legitimate?
Look for a real local address, proof of license where required, insurance, and reviews on independent sites. A legitimate locksmith gives a clear quote before starting and shows ID when they arrive. The FTC suggests researching a locksmith ahead of time and saving their number, so you’re not choosing in a panic.
Do locksmiths need a license?
It depends on where you live. Some U.S. states require locksmiths to be licensed, while others don’t. If your state does, ask to see the license before work begins. Even where it isn’t required, look for insurance, training, and good independent reviews before you hire anyone.
Should a locksmith drill my lock during a lockout?
Usually not. Skilled pros can open most standard home locks without drilling. Drilling might be needed for some high-security or damaged locks, but it shouldn’t be the first step for a basic lockout. If someone insists on drilling right away, ask why and get a clear price first.
