Key Stuck in Lock: What to Do and What It Costs

Your key is in the lock and it will not turn. Or it turned, and now it will not come back out. Or the worst version: it moved barely at all, something gave, and you are holding the bow of the key while the blade sits inside the cylinder. You are on your own doorstep, it is dark, and the first search result is a phone number with a fifteen dollar call-out fee printed next to it.

Stop turning the key. That is the one thing that changes the size of the bill, and it is the one thing almost everyone does anyway. A key that binds is usually telling you a cheap thing is wrong. A key that snaps has just made it an expensive thing.

Locked out right now? Start with what to do while you wait for a locksmith, which covers the questions to ask on the phone before anyone is dispatched to you. If you are safe and the situation can wait, read on first. What you say on that phone call changes what you get quoted.

Key Takeaways

• Forcing a binding key is what converts a cylinder problem into a lock replacement. Once the blade breaks off inside, the cheapest possible outcome is gone.
• Three different faults feel identical at the door: the key will not turn, the key will not come out, the key broke. They have different causes and different bills.
• Advertised locksmith prices in Canada start at $15 for a call-out and $35 for a minimum job, but both published rate pages checked for this guide state in their own words that the final cost will vary (Locksmith In Vancouver, page updated 12 March 2024; Locksmith In Calgary, page updated 8 April 2021, both retrieved 3 September 2026).
• Advertising a price you cannot actually pay is drip pricing, and the Competition Bureau treats it as false or misleading under the law unless the extra charge is a government one such as sales tax (Competition Bureau Canada, retrieved 3 September 2026).
• If you rent, a lock that failed on its own is generally the landlord’s repair, not yours.

Why forcing a stuck key is the expensive decision

Keys are cut from soft alloys on purpose, so that the key wears out before the lock does. It is a deliberate trade: a worn key costs a few dollars to recut, a worn cylinder costs a service call. That softness is also why extra force works so badly here. The moment you reach for pliers or put your weight behind the bow, you are applying force to the weakest part of the whole system.

There is a second reason, and people find this one harder to accept. In most stuck-key situations the cylinder is not the thing that is broken. A door that has shifted with the season, a deadbolt binding against a strike plate that no longer lines up, a latch under load because the frame moved: none of those are fixed by turning harder, and all of them feel exactly like a stiff lock from where you are standing. You are pushing against a door frame and blaming a key.

So the sequence that keeps the bill small is short, and none of it involves working on the lock. Stop applying force. Note precisely what the key did, because the three faults below get quoted differently. Then call someone and describe it accurately. If the key is already broken, leave the piece exactly where it is, because what a locksmith can do with it depends on it not having been disturbed.

Three problems that feel the same at the door

The key goes in but will not turn

This is the alignment family. Something is loaded: the bolt against the strike, the door against a swollen frame, or a cylinder full of the grit that a winter of salt and slush leaves behind. It is also what a worn key does. A key cut from a copy of a copy drifts a little further from the original dimensions with each generation, and eventually it lifts the pins to nearly the right height instead of exactly the right height. That key works in July and fails in February, which is why people are convinced the cold broke their lock.

The key turns but will not come out

This one is usually mechanical rather than dirty. Something behind the cylinder is not returning to its rest position, or the cylinder has rotated slightly out of alignment with its housing. On a car it is a different situation again, because ignition cylinders on many vehicles will deliberately hold the key until the transmission and the ignition position agree with each other. That is the system working, not failing.

The key broke off inside

Metal fatigue does not announce itself. A key that has been flexing slightly every day for years develops a stress line, usually where the blade meets the shoulder, and then one ordinary Tuesday it goes. The lock is often completely fine. What matters now is whether the piece can come out without the cylinder coming apart, and that is not a question anyone can answer from the outside.

What a locksmith is actually trying to do

Understanding the two possible outcomes is what lets you approve the right work instead of nodding at a number. A locksmith attending a stuck or broken key is aiming for one of two results, and they are priced very differently.

The good outcome is that the key comes out and the existing cylinder still works. You pay for the attendance and the labour, you get a new key cut, and the lock on your door is the same lock it was this morning. The other outcome is that the cylinder is damaged, seized, or has to come apart to clear it, so it gets replaced. Now you are paying for attendance, labour and hardware, and if that lock was keyed to match other doors in the building, you are paying to have the new one matched too or you are walking around with an extra key.

The question to ask on the phone, before anyone is dispatched, is which outcome they are quoting for. The question to ask on the doorstep, before work starts, is what the price becomes if the first approach does not work. Anyone who does this for a living can answer both. Getting a straight answer to the second one is the single most useful thing you can do, because that is the point where an attendance charge quietly turns into a hardware bill.

What it costs, and why the advertised number is not the number

Canadian locksmiths who publish rates at all tend to publish an entry price rather than a price. Here is what two of them advertise, taken directly from their own rate pages.

Advertised minimum estimates as published on each company’s own rates page. Sources: Locksmith In Vancouver rates (page last modified 12 March 2024) and Locksmith In Calgary rates (page last modified 8 April 2021), both retrieved 3 September 2026. These are asking prices from two published price lists in two cities. They are not verified totals paid by customers, and they are not a national average.

Read the asterisks, because both pages carry them. Each page states that the figure is a minimum estimate for the respective job, that the final cost will vary with the security level of the lock system plus labour charges, and that complications found on site may change the price. That is a legitimate thing for a business to say, and saying it plainly is better than not saying it. It is also the entire gap between the number that got you to dial and the number on the invoice.

The Competition Bureau has a name for the version of this that crosses the line. Drip pricing, in the Bureau’s words, “involves offering a product or service at a price that is unattainable because consumers must also pay additional charges or fees to buy the product or service,” and it “is considered to be false or misleading under the law, unless the additional charges or fees are imposed by the government, such as sales tax” (Competition Bureau Canada, Drip pricing, retrieved 3 September 2026). The Bureau’s stated expectation is that the price a consumer sees advertised is the one they will pay.

A published minimum with a visible caveat is not that. A headline price that bears no relation to the invoice, with nothing explained before the work started, is a different animal. The practical defence is boring and it works: get the range by text or email before dispatch, ask what pushes a job to the top of that range, and refuse to authorise extra work you have not been quoted for. This site does not publish a national price for this job, because no data set exists that would support one. What it publishes instead is how each listing is checked. Fee ranges shown on a listing are entered by the business and published with a date attached rather than verified, which is the honest limit of what any directory can tell you before you dial. If a company quotes you one number and charges another, you can report a listing.

If you rent, this is probably not your bill

Tenancy law is provincial, so the details differ across the country and you should check the rules where you live rather than assume. Two provinces publish their position clearly enough to quote.

In Ontario, the Landlord and Tenant Board’s interpretation guideline on maintenance obligations restates section 20 of the Residential Tenancies Act: “A landlord is responsible for providing and maintaining a residential complex, including the rental units in it, in a good state of repair and fit for habitation.” The same guideline sets out the limit, citing section 34: “the tenant is responsible for the repair of any undue damages to the rental unit or residential complex caused by the wilful or negligent conduct of the tenant” (Tribunals Ontario, Interpretation Guideline 5, retrieved 3 September 2026).

British Columbia is more explicit about locks. The province lists “locks on doors and windows” among the things a landlord must maintain, and names “damaged or defective locks that give access to a rental unit” as an emergency repair. It also states that tenants are responsible for repairing damage caused by people and pets living in or visiting the unit, and that where a landlord cannot be reached after two attempts, a tenant may arrange emergency repairs at a reasonable cost (Province of British Columbia, Repairs and maintenance, retrieved 3 September 2026).

Put those together and the practical rule for a tenant reads like this. A lock that failed on its own is the landlord’s problem. A lock you broke is yours. The line between the two is exactly why you should not force a binding key before anyone has looked at it. Call the landlord or property manager first, in writing, and keep the message. If you end up paying when you should not have, that written record is what gets it back.

What makes locks stick in the first place

The honest answer is time and weather, in that order. A cylinder is a small machine with tight tolerances, sitting outdoors, in a country where the same door faces heat in July and deep cold in January. Metal moves. Wooden frames take on moisture in spring and give it back in autumn. The strike plate that lined up perfectly in October is out of true by March, and that small difference is the whole clearance the bolt had to work with.

Two habits prevent most of this. The first is to stop carrying a bent or visibly worn key: get a fresh one cut from the best copy you own rather than from the one that lives in your pocket, then retire the pocket one. The second is to treat a lock that has started needing a wiggle as a lock asking for attention, not a lock with a personality. Stiffness is a warning, and acting on a warning is much cheaper than acting on a broken blade. If the door itself has started catching or dragging, the lock is not the problem and no amount of key replacement will fix it.

Car keys follow a different curve, because the failure there is usually electronic rather than mechanical. If the problem is a fob rather than a blade, the guides on what a replacement key fob costs in Canada and fob battery replacement cover those separately.

Frequently asked questions

Should I spray lubricant into the lock?

It rarely addresses the actual fault. If the door frame has moved or the key is worn, no spray changes either one, and a general-purpose oil left in a cylinder attracts the grit it was meant to displace, which makes the next winter worse rather than better. A lock that has been stiff for weeks is a service call, not a product problem.

Is a stuck key an emergency call?

It is if you cannot secure the door, or you cannot get in and have nowhere else to go. It is not if you are inside, warm, and the back door works. Emergency and after-hours attendance is quoted separately from a scheduled visit, so say on the phone which of the two you actually need.

My key snapped off. Is the lock ruined?

Often it is not. A key breaks because the key was tired, not because the cylinder failed, and a broken blade sitting in an otherwise healthy lock is a better starting position than a seized cylinder with an intact key in it. Whether the cylinder survives depends on how the piece sits and on whether anyone has been digging at it, which is the argument for leaving it alone.

Do I need a licensed locksmith for this?

Locksmith licensing in Canada is set provincially and municipally, and the requirements are not the same across the country, so the answer depends on where you are. Rather than list provinces from memory, this site looks up each listed company in the provincial corporate registry, re-runs that check monthly, and records the licence detail it was able to obtain where a province licenses the trade. What that check does and does not prove is set out in the verification methodology.

The one thing to do now

Take the pressure off the key and leave it where it is. Then make one phone call in which you say which of the three faults you have, ask for a price range rather than a starting price, and ask what that range becomes if the first approach does not work. Get the answer before anyone is dispatched. It costs you nothing, and it is the difference between a service call and a surprise.

When you are ready to find someone, browse locksmiths by province and read what could be verified about each one before you dial. The other locksmith guides on this site cover the cost questions in more depth.
