Locksmith service covers home lockouts, rekeying, lock changes, new deadbolts, smart lock installs, key copies, and car lockouts. A locksmith can get you back inside, make old keys stop working after a move or a lost key, or fit new hardware to your doors. Call Swupi and we connect you with an independent local locksmith company that serves your area, so you can talk through the job and get a quote. You agree on the work and timing with that company directly.
What can a locksmith help with?
Locksmiths handle more than lockouts. Common reasons homeowners call:
- Lockouts: you are locked out of your house, garage, or car.
- Rekeying: the lock stays, but the inside is changed so old keys stop working. It is a common step after moving into a new home, losing keys, or when a roommate or tenant moves out.
- Lock changes: replacing worn, broken, or outdated locks with new hardware.
- Deadbolts: adding a deadbolt to an exterior door.
- Smart locks: installing keypad or app-controlled locks.
- Key copies: spare house keys, plus car keys and fobs for many vehicles.
If you are thinking about cameras, alarms, or a video doorbell along with new locks, see our home security guide.
Which types of door locks can you choose from?
A locksmith can help you pick hardware that fits your door and how you use it. The most common options for homes:
| Lock type | How it works | Often used for |
|---|---|---|
| Knob or lever lock | Lock built into the handle, usually with a key outside and a turn button inside | Interior doors, and paired with a deadbolt on exterior doors |
| Single-cylinder deadbolt | A key on the outside and a thumb turn on the inside | Front, back, and side doors |
| Double-cylinder deadbolt | Needs a key on both sides | Doors near glass panels; check local codes first, since a key is needed to get out |
| Keypad or smart lock | Opens with a code, a phone app, or a key, depending on the model | Homes where family, guests, or sitters come and go |
| Mortise lock | A lock body set into a pocket cut in the edge of the door | Some older homes and heavy entry doors |
Lock hardware is often graded under the ANSI/BHMA standard, from Grade 1 (the highest rating) to Grade 3 (basic residential). Ask the locksmith which grade a lock carries and whether it fits the thickness and existing holes of your door.
For a double-cylinder deadbolt, think about how everyone in the home would get out in a fire. If the key is not close at hand, it can slow an exit.
How do you avoid locksmith scams?
Some locksmith scams start with a vague answer on the phone and end with a surprise at your door. The Federal Trade Commission has warned that some locksmiths advertising locally may not be local at all, and recommends finding a locksmith before you need one and saving the number in your phone.
Tips from state consumer protection agencies:
- Ask for the business name. Wisconsin's consumer protection office says to be wary if a company answers with a generic phrase like "locksmith services" and will not give its legal business name.
- Get a written quote before work starts. Ask for it to cover all work and parts, and ask what could change it.
- Check ID when the locksmith arrives. Ask for identification and a business card, and see that they match the company name you were given and the vehicle.
- Be cautious about drilling. In a lockout, be skeptical if you are told right away that the lock must be drilled and replaced.
- Keep the paperwork. Ask for an itemized record that lists the parts and labor.
Some states license or register locksmiths. California requires a license, which you can check through the state, according to the California Department of Consumer Affairs. Connecticut requires registration and has issued a consumer alert about scammers posing as locksmith technicians. Check with your state's consumer protection or licensing office to see what applies where you live.
What happens when you call a locksmith?
Whether it is a lockout or a planned lock change, most calls follow the same steps.
- Describe the job: say what kind of door and lock it is, how many locks, and whether you want to rekey or replace.
- Get a quote up front: ask what it covers, including labor and parts, before anyone heads out.
- Confirm who is coming: ask for the company name and the name of the person being sent.
- On arrival: check the locksmith's ID and business card. The locksmith may ask for proof that you live at the address before opening a door.
- Before work begins: if the quote changes, ask why, and get the new version in writing before you agree.
- When it is done: test every key and lock, and keep the itemized paperwork.
Many locksmith companies take after-hours calls, so ask about timing when you call. When you call through Swupi, you speak with an independent local company, and you agree on the work and timing with them directly. See how Swupi works.
Should you rekey, replace, or upgrade to a smart lock?
The right choice depends on why you are calling.
- Rekey when the locks work fine and you just want old keys to stop working, such as after a move or a lost key. The locksmith changes the pins inside the lock and gives you new keys.
- Replace when locks are worn, damaged, or hard to turn, or when you want a new style or a sturdier grade of hardware.
- Upgrade to a smart lock when you want keypad or app entry, or want to give temporary codes to guests or service visitors.
Ask the locksmith whether your doors need any work to fit new hardware, and ask to have the old parts returned to you if they are replaced. For a smart lock, ask whether it has a backup key, how it warns you when the batteries run low, and how it connects with any alarm or camera system you already have. Our home security guide covers those systems.
Locksmith questions, answered
What should I do if I'm locked out of my house?
First check whether someone in your household, a neighbor you gave a spare to, or your landlord has a key. If not, call a locksmith company and describe the door and lock. Ask for the company name and a quote before anyone heads out, and have ID ready, since the locksmith may ask for proof that you live there.
Should I rekey or replace my locks?
If your locks work well and you only need old keys to stop working, rekeying is often enough. Replace them when they are worn, damaged, or hard to turn, or when you want a different style or a smart lock. A locksmith can look at your doors and explain both options.
How can I tell if a locksmith is legitimate?
Ask for the company's legal business name, a written quote before work starts, and ID when the locksmith arrives. Wisconsin's consumer protection office warns about generic phone greetings and quick claims that a lock must be drilled. Some states, such as California, license locksmiths, so check with your state.
Should I rekey my locks after moving into a new home?
Many homeowners do. Past owners, tenants, contractors, or neighbors may still have keys, and you have no way to know how many copies exist. Rekeying makes all old keys stop working while you keep the same lock hardware.
Can a locksmith install a smart lock?
Yes, many locksmiths install keypad and app-controlled locks. Ask whether your door needs any changes to fit the lock, whether the lock has a backup key, and whether setup with your phone app or alarm system is part of the job.
