Before We Start
Four Things We Make Clear First
Price, permission, entry method, and proof — settled before any work begins.
- Price Clarity From £89, with no separate call-out fee. We confirm the full price — labour, parts and any extras — and you only pay if you accept the quote.
- Rightful Access For your protection, we may ask for proof that you live at the property or have permission to enter. If rightful access cannot be confirmed, we may decline the job.
- Careful Entry Route We explain the entry method first and try the least invasive option where possible.
- Proof on Request We can show ID, insurance details, invoice information, and warranty terms when needed.
Common Situations
When You Need Us Most
Tell us what has happened and we will confirm the safest next step before you choose whether to go ahead.
-
Keys Inside or Door Slammed Shut
Door closed behind you, keys inside, lock engaged. Tell us the door and lock type, and we explain the least invasive entry route before you decide whether to go ahead.
-
Keys Lost or Stolen
If keys are missing, we can help you regain access and discuss whether the cylinder should be changed so old keys no longer work.
-
Broken Key or Jammed Lock
Key snapped or broken off in the lock? Avoid forcing it or pushing the other half in. We assess the lock on site and explain extraction, repair, or replacement before we begin — often the broken piece can be removed and the lock reused. Lock seized or the key will not turn at all? Tell us; that is often a mechanism fault we can repair.
-
uPVC, Composite or Smart Locks
Multipoint doors and smart locks need careful diagnosis. We confirm the lock type, condition, and the access route before using specialist tools.
-
Child or Pet Inside
If anyone is in immediate danger, call 999 first. When everyone is safe, tell us at the start and we will help with the lock as quickly as we can.
-
Smart Lock or Dead Battery
Smart locks can fail when the battery dies or the electronics glitch. We carry tools and bypass methods for common smart cylinders, so you are not left waiting on the doorstep. Tell us the brand when we arrive.
Our Process
How We Get You Back In
Three clear steps from first contact to getting back inside.
-
Call and Confirm
Have your postcode and door type ready — it helps us quote faster. We confirm whether we can attend, agree the ETA before we set off, and quote before dispatch. Often with you in 30–60 minutes.
Quote and ETA first -
Attend and Assess
On arrival, we confirm your right to enter, inspect the lock and door, and explain the safest practical entry route before tools come out.
Permission and method -
Entry, Check and Payment
We attempt the least invasive method first where conditions allow; many domestic lockouts are open in 5–15 minutes. After entry, we check the lock, explain any parts or warranty position, and take payment after the agreed work is complete.
Agreed work complete
Our Methods
Non-Destructive First, Where Possible
We assess the lock and door first, then attempt non-destructive entry where the condition and safety checks allow.
Lock and Door Assessment
Before choosing a tool, we check the lock type, door alignment, cylinder condition, handles, and frame. That helps us choose the most suitable route before any entry attempt.
Broken Key Extraction
When a key snaps in the lock, we locate the fragment, align the cylinder, and remove the broken piece with extraction tools suited to the lock, where the cylinder allows. Done early, before it is forced deeper, this often saves the existing lock, so you are not paying for a new cylinder you did not need. If the fragment cannot be removed safely, we explain why replacement is the cleaner route.
Lock Picking
Skilled manipulation of the lock mechanism using specialist tools. This is usually the first route when the lock condition makes it appropriate.
Bypass Methods
Techniques that work around the lock mechanism entirely, often using door furniture or frame gaps. We only use these where they are suitable for your door type.
Cylinder Replacement When Needed
If careful entry is not suitable, cylinder replacement may be the cleanest route. We explain the reason, price, new keys, and warranty position, and ask for your approval first.
If a Cheaper Fix Will Hold
Where a cheaper route will do the job, we tell you. We explain the options and the cost of each, and you choose.
While You Wait
What To Do Right Now
Simple things you can do in the next few minutes while you wait.
- Stay Safe and Visible Wait near a well-lit area or with a neighbour where you can, especially at night.
- Have ID Ready If you can, have ID to hand so we can confirm rightful access quickly when we arrive.
- Do Not Force the Door Forcing it can cause damage that is far more expensive to put right.
- Danger? Call 999 First If a child, vulnerable person, or pet is at immediate risk, call 999 first — then call us for the lock.

What Our Customers Say
Real experiences from real people we've helped.
We had a break-in last month and I was a complete mess afterwards. Trulox came out same day to board up and change all the locks. What I appreciated most was they didn't rush me - took time to explain what they were fitting and why. Made me feel safe in my own home again which sounds dramatic but it's true. Would definitely recommend to anyone in a similar situation, they really do care.
Danny was very helpful and explained everything that he suggested needed doing to effect my door lock repair. Where there were choices for me to make, he explained in detail the benefits of each lock. He told me the cost of each solution and left it for me to decide. I am really happy with the finished work. Thank you.
I had George from Trulox, come and fix the lock on my door. He came out the same day and was friendly, professional and conscientious. I was very happy with the job he did and would highly recommend.

Common Questions About Lockouts
Direct answers to the questions customers ask most before calling.
How much does emergency lockout entry cost?
Price Clarity
Emergency lockout entry starts from £89. Before work starts we confirm the quote and explain anything that changes it — labour, parts, specialist access, or any extra repairs. There is no separate call-out fee when you accept the quoted work.
Do you offer an out-of-hours or late-night locksmith service?
Open Late
Yes. We work out-of-hours, open late until midnight, seven days a week — never a call centre; you speak directly to a locksmith, and we're typically with you in 30–45 minutes. If you need us after midnight, message us on WhatsApp and we reply when we reopen at 8am.
Will you damage my door or lock to get me in?
Non-Destructive First
We attempt non-destructive entry first where the lock, door condition, and safety checks allow. If drilling, cylinder replacement, or any damage risk is unavoidable, we explain why and ask for approval before proceeding.
Do I need to prove I live at the property?
Rightful Access
We may ask for evidence of your right to enter, such as photo ID, proof of address, tenancy or ownership evidence, or authorisation from the occupier or owner. If rightful access cannot be confirmed, we may decline the job.
What if my key has snapped or broken off in the lock?
Broken Key
A snapped or broken key can often be extracted on site, so the existing lock is not always damaged or replaced. Do not force the key, push the other half in, or dig at it with improvised tools, as that can drive the piece deeper and turn a quick extraction into a costlier repair. A Trulox locksmith assesses the lock on site, explains whether extraction, repair, or cylinder replacement is the safest route, and confirms the price before any work begins.
Can you remove a snapped key without drilling or replacing the lock?
Snapped Key Removal
Often, yes — where the lock allows, a Trulox locksmith can remove the broken piece and reuse the cylinder, so your existing keys still work. We check this first; if the fragment cannot be removed safely, we explain why replacement is the cleaner route and confirm the parts price before fitting, and you only pay if you accept the quote.
Can you help with uPVC, composite, or smart locks?
Specialist Doors
Yes. uPVC, composite, and smart locks often need specialist diagnosis because the issue may involve the cylinder, multipoint mechanism, door alignment, batteries, or electronics. We explain the likely route before work starts.
What if a child, vulnerable person, or pet is locked inside?
Safety First
If anyone is in immediate danger, call 999 first. When everyone is safe, tell us at the start of the call and we will help with the lock as quickly as we can.
Do you provide warranty, invoices, or insurance details?
Proof & Warranty
Attending Trulox locksmiths are DBS-checked and covered by £2m public liability insurance. We can show ID and insurance details on request. Completed workmanship is covered for 12 months, subject to warranty terms and normal use, and parts are covered under the applicable manufacturer or product warranty.
What should I do while waiting for the locksmith?
Practical Advice
Stay somewhere safe and visible. If you are outside at night, wait near a well-lit area or with a neighbour where possible. Have identification ready if you can, and avoid forcing the door because it can cause expensive damage.
