Locked Out of an Old Safe? Your Options, Costs and Who to Call

An old safe with no key or combination is one of the most common problems owners bring us, and it’s rarely as bad as it looks: a professional can almost always open it, often without damage. Here’s how to check first, what it costs, and who to call.

First, check that you really are locked out

It sounds obvious, but before you pay for an opening, look properly for the key or the combination. A San Diego locksmith referral service puts it bluntly: combinations “are often written in address books, desk drawers, or bank safe-deposit envelopes”, so spend an hour looking before hiring a professional.¹ Keys turn up in the same kinds of places. Work through this list:

Keys	Key hooks and key boxes, desk and bureau drawers, jewellery boxes, envelopes in a filing cabinet, a bank safe-deposit box, the solicitor’s or executor’s file.
Combination	Address books, diaries, desk drawers, envelopes with bank papers, the back of photographs or cards kept with the deeds.
Paperwork	Receipts, invoices, service labels and letters from a safe company. They can name the maker and lock, and sometimes the engineer who last serviced it.
People	The seller or their estate agent, the executor, relatives, a former business partner, the firm that cleared the house.

If you find a combination but it won’t open the door, stop after a few careful attempts. Old dial locks are dialled in a set sequence of turns, and a worn lock can be fussy; a safe engineer can usually sort that out cheaply while the safe is still intact.

Your options: how a professional opens an old safe

Safe opening is a specialist trade. In the UK the Master Locksmiths Association runs a separate search for safe engineers, and in the US the Safe & Vault Technicians Association exists solely for safe and vault technicians.³⁴ What they do falls into three broad approaches. You don’t need to know how any of them work. You do need to know which one you’re being offered, and what it means for your safe.

Ireland’s Health and Safety Authority, writing about the asbestos risk in old safes, is clear about which comes first:⁵

“Most safes that are fitted with a mechanical lock can be opened by an expert technician without resorting to drilling.”

Health and Safety Authority (Ireland), 2023

Experts don’t all agree on old British key-locked safes. A UK safe engineer who regularly opens Chubb, Milners, John Tann, Hobbs Hart, Chatwood and Ratner safes says older British lock mechanisms “manipulate well”.⁶ On the other hand, when an owner in Wellington, New Zealand found a locked Milner safe under the stairs in 2007, contributors to the antique-locks.com forum judged that drilling was “the best (and probably only) option” for that type of lever lock, and a job “best left to a specialist”.⁷ Which approach suits your safe depends on the maker, the lock and its condition, which is exactly why it pays to find an engineer who knows old safes.

What it costs to open an old safe

Prices below are published figures from trade firms, a US trade survey and an Australian price guide. They’re a guide to what’s normal, not a quote. Expect call-out or travel charges on top in rural areas, and note that repairs after a drill opening are usually billed separately.⁸

Where	Job	Published price
UK	Safe opening, daytime (7am to 10pm)	£120–£250, no open no fee6
UK	Safe opening, overnight	£170–£3206
UK (London)	Safe opening, fixed price agreed first	£120–£250 plus VAT9
UK	Copy of a surviving safe key	from £23.25; double-bitted from £38.6010
US	Opening by manipulation / by drilling (national averages)	$318 / $41411
US	Combination change	$13011
US	Safe opening, 2026 national average	about $440, repairs extra8
Australia	Safe opening or combination reset, typical (range)	Sydney A$400 (230–690), Perth A$370 (210–630), Hobart A$315 (180–540)12

An antique safe can cost more than a modern one if it needs a specialist, a long manipulation or parts made for an old lock. The reverse also happens: a safe that turns out to have a simple fault can be opened in minutes. Either way, ask for a fixed price, or a clear maximum, before the engineer starts.

How long does it take?

• Most domestic safes: under an hour, according to one UK engineer.⁶
• Drill and repair: a US firm says most burglary-rated safes can be drilled open and repaired in one to two hours.⁸
• Hard cases: much longer. In 2013 a Houston locksmith spent over 20 hours on one old safe with concrete walls.¹³ On the 2007 Milner thread, one poster guessed a fully hand-worked opening could take days.⁷

Small safes can sometimes go to the engineer’s workshop instead of a home visit; some MLA members have shops that take them.³ Before you arrange that, check the weight: even small Victorian safes are far heavier than they look. Our safe weight calculator gives an estimate from the outside measurements.

Will opening it damage the value?

For an antique safe, what buyers value is the safe itself: maker, age, original paint and plates, and a lock that works with its own key. How it was opened decides how much of that survives.

• Opened without damage: nothing is lost. If the engineer can also supply a working key or set a new combination, the safe is worth more than it was locked.
• Drilled and repaired by a professional: a small sealed hole and a repaired lock. A collector will notice it, but the safe still works, which is what most buyers want.
• Cut, prised or burnt open: the door, hinges and paintwork are usually beyond sensible repair. At that point an ordinary old safe is often worth little more than its weight in scrap.

So is a safe worth more unopened? Only to a gambler. Locked safes do sell at auction on the chance of something inside, but the contents rarely justify the price: a buyer at a town auction in Groton, Massachusetts paid $150 for an unopened safe and found $100 inside.¹⁴ If you plan to sell, an intact, working safe with a known maker is the better offer. Not sure what yours is? Our owner’s guide, I have an old safe: what now?, covers identifying, valuing, moving and selling it.

Anything we say about value is an informal view, not a professional appraisal.

How to find a qualified safe engineer

Start with a trade body’s own directory rather than whichever advert comes top of a search. Each of these runs a free public search:

UK	Master Locksmiths Association (MLA): “Find a Safe Engineer Near You”. Member companies are vetted, regularly inspected and criminal record checked, and employ a locksmith who has passed the MLA qualification.3 Check the licence number on the listing.
US	Safe & Vault Technicians Association (SAVTA), Dallas: “Safe Tech Search” to find a qualified technician.4
Australia and New Zealand	Master Locksmiths Association of Australasia (MLAA): “Find a Master Locksmith”. Ask specifically for a member who does safe work.15

Then ask a few questions before anyone visits:

• 1 Do you open antique safes, and this maker in particular? Send the photos of the plate and lock.
• 2 Will you try a non-destructive opening first?
• 3 What is the fixed price or maximum, and is there a charge if you cannot open it?
• 4 If you have to drill, will you repair the lock and leave the safe working, with a key or a new combination?
• 5 How do you handle a safe that may contain asbestos?
• 6 What proof of ownership do you need?

Proof of ownership: what to have ready

A reputable engineer won’t open a safe for just anyone. One UK firm states “Proof of ownership required on all jobs” and, for a home, asks for photo ID showing the address plus something such as a utility bill.⁶ For a safe you inherited, a US referral service lists a receipt, inheritance paperwork or an affidavit, with ID that matches.¹ Useful documents:

• Your house: photo ID with the address, and a utility bill or council tax letter. For a recent purchase, the completion statement.
• An inherited safe: the will or grant of probate (letters of administration in some places), or a letter from the executor saying you may have the safe opened.
• A rented property or a business: written permission from the owner or landlord.
• A safe you bought: the receipt or auction invoice.

An engineer who asks no questions at all is a warning sign, not a convenience.

Found a locked safe in a house you bought?

This is where most locked-safe stories start, and it raises two questions: is the safe yours, and is whatever is inside it yours? The answers depend on your contract and on local law, so treat what follows as general information, not legal advice.

The safe itself

Check what the sale included. In England and Wales the seller fills in the Law Society’s Fittings and Contents form (TA10), which records which items stay and which go.¹⁶ A safe built into a wall or bolted to the floor is likely to have been treated as part of the house; a free-standing one may have been listed, excluded or simply forgotten. If it isn’t mentioned, ask your conveyancer to contact the seller’s side before you open it. A safe set into a concrete floor has questions of its own, covered in our guide to old floor safes.

What is inside

Owning the house doesn’t automatically make you the owner of what’s found in it:

• Scotland: the law says outright that neither finding property nor owning the premises where it is found gives you, by that fact alone, a right to claim it.¹⁷
• England and Wales: under the Theft Act 1968, keeping someone else’s property is not treated as dishonest if you believe the owner cannot be discovered by taking reasonable steps.¹⁸ Valuables left by a previous owner can usually be traced through the seller or the estate, so that is unlikely to apply.
• Ireland: a buyer is normally entitled to vacant possession, and goods left behind after closing generally still belong to their original owner or estate, unless the sale included the contents.¹⁹
• United States: rules vary by state; some favour the finder when no owner can be identified, others require a report to the police.²⁰

Two real cases show how this plays out. In Toledo, Ohio, a man who bought a house for $1,000 found about $10,000 in the basement, traced a former occupant who had lived there from 1946 to 1967, and split it with him.²⁰ In Houston in 2013, an old safe given away for scrap after its owner’s death turned out to hold gold Krugerrands and silver dollars; the police took temporary custody, and the coins went back to the family.¹³

The safest approach: tell the seller, agent or executor before you open it, have someone independent present when it is opened, photograph and list the contents, and take legal advice if anything valuable turns up.

Red flags: how to avoid a rogue locksmith

Rogue traders use search adverts and low prices to win the call, then charge far more on arrival. Which? describes this “bait and switch pricing”, including a case where a quoted £60–£120 became £500.²¹ Watch for:

• A very cheap advertised price. The MLA calls it “the number one sign of a rogue locksmith”.²²
• A call centre instead of a locksmith, or someone who will not name the engineer coming out.²¹²²
• A firm that is not local at all. The US Federal Trade Commission has warned that some locksmiths advertising locally are not local and may lack professional training.²³
• A quote by phone without photos or questions. Which? suggests sending a photo of the job so the price can be accurate.²¹
• Drilling straight away. “Always be wary if a locksmith immediately attempts to drill,” says the MLA.²²
• Claims you cannot check: trade body approval, “police approved” (the MLA says police do not approve locksmith firms) or insurer-approved work. Check membership in the trade body’s own directory.²²
• An offer to buy the safe, unopened, on the spot. Find out what it is before you accept anything.

Asbestos: why you must not drill or cut it yourself

Many old fire-resisting safes have a packing material sealed inside the walls and door. Ireland’s Health and Safety Authority says asbestos was used by some safe makers “into the late 1990s”, as woven door seals and as packing sealed inside doors and walls, and advises that safes made before 2000 be checked.⁵ Its guidance on opening:

• Sealed-in filling is not a risk in normal use.
• Where a pre-2000 safe cannot be confirmed asbestos-free, it must be presumed to contain asbestos.
• Destructive cutting of such a safe must not be permitted, because it could release fibres from the packing.
• If precision drilling is needed, it should be done by a competent safe technician working with a specialist asbestos contractor, and the hole securely resealed.

An angle grinder, a crowbar or a drill in an amateur’s hands is the one way to turn a locked old safe into a health hazard. Leave it shut until a professional has seen it.
