It’s 10 PM on a Tuesday, the Denver wind is biting, and your keys are sitting on the kitchen counter on the other side of a locked door. It feels like a disaster, but a lockout is one of the most solvable problems there is, as long as you stay safe and call the right person. Here’s what to do, what it should cost, and how to avoid getting overcharged.
First: get somewhere safe and warm
Before you call anyone, get out of the cold and somewhere well lit: your car, a neighbor’s porch, a nearby store. Then work through the quick checks:
- Try every other door and window you can reach safely, including the garage.
- Call anyone with a spare key: a partner, roommate, neighbor or your property manager.
- Don’t force the lock. Prying, kicking or using a credit card often damages the door and makes the fix more expensive.
- If a child, pet or someone at risk is locked inside, call 911 first.
Your lock doesn’t need to be destroyed
A professional locksmith opens most home lockouts with non-destructive entry: specialized tools that work the lock the way a key would, without drilling. Your existing lock keeps working afterward, and you don’t have to buy new hardware the next day.
If someone suggests drilling a standard residential lock right away, ask why. Drilling is sometimes necessary, but it should be a last resort with a clear explanation, not the first step.
How to tell you’ve called a real local locksmith
Colorado doesn’t license locksmiths at the state level, which makes it easy for national dispatch call centers to pose as local shops. A common trick is advertising a “$15 service call,” then charging far more once the door is open.
Before anyone touches your door, check for:
- A marked vehicle, not an unmarked personal car.
- A uniform or ID badge with the company name.
- A written estimate before any tools come out.
- A request for your ID. A real professional checks that you live there before opening anything.
- Proof of insurance if you ask for it.

What you’ll pay for a lockout
A fair lockout bill has up to three parts, and you should know each one before work starts:
- Service call fee: covers the trip to your location.
- Labor: the work of opening the lock.
- Parts: only if something actually needs replacing.
If you’ve lost your keys rather than locked them inside, consider rekeying while the locksmith is there. Instead of replacing the doorknob, the locksmith swaps the small pins inside the lock so any lost key stops working. It costs much less than new hardware. More on rekeying.
Locked out of your car instead?
Picture leaving a grocery store in Aurora: the key turns but the engine won’t start, or the key snaps off in the ignition. Modern car keys contain a chip that “talks” to the car, and when that fails you need the key reprogrammed or replaced, not just copied.
A mobile locksmith can usually do this where the car is parked, so you don’t need a tow to the dealership. If a key breaks in the ignition, don’t reach for pliers; that pushes the piece deeper. A locksmith uses a thin extraction tool to hook the fragment out, then cuts and programs a new key on the spot. More on car lockouts and car keys.
When Denver’s cold jams your lock
Sometimes the problem isn’t a lost key but a lock that won’t turn on a freezing morning. Moisture inside the cylinder can freeze, and cold makes the small parts stiff. Before assuming the lock is broken:
- Don’t use household oil. It collects dust and turns into sludge that jams the lock later.
- Use a dry lubricant like graphite powder, which keeps the pins moving without residue.
- Don’t force the key. That’s how keys snap off inside the lock.
If the lock still sticks once it warms up, the door frame may have shifted. A locksmith can adjust the strike plate so the bolt lines up again.
If your keys were lost or stolen
Losing keys at a crowded LoDo event is more than an inconvenience if your house key and car key were on the same ring. Assume whoever has them could find your address. Secure your car first, then rekey your home’s exterior locks so the lost keys no longer work. It’s usually the same day and doesn’t require new hardware.
It’s also a good moment to think about an upgrade:
- Standard deadbolts: strong and simple, but you still carry a key.
- Keypad locks: a PIN code instead of a key, so you can’t lock yourself out.
- Smart locks: control from your phone and temporary codes for guests or dog walkers. See smart lock installation.
Your 3-step lockout plan
- Save a local locksmith’s number now, before you need it. Look for a real local address, clear pricing and good reviews.
- Leave a spare key with someone you trust, not under a mat or a fake rock.
- Know your building’s rules. If you rent, find out whether your property manager handles lockouts or has to approve a locksmith.
Common questions
Will a locksmith have to drill my lock?
Usually not. Most residential lockouts are opened without damage using non-destructive tools. Drilling should only happen after the locksmith explains why it’s needed.
What should I show the locksmith?
A photo ID with your address, or a lease, utility bill or other document showing you live there. For cars, your ID and registration or title.
Should I rekey after a lockout?
If you locked your keys inside, no. If they were lost or stolen, yes. Rekeying makes the missing keys useless without replacing your locks.
What if I’m locked out of an apartment?
Call your property manager first. Many buildings need to approve or arrange the locksmith, and some have a maintenance contact who can let you in.
