Emergency Locksmith Prices

There may be an occasion where you find yourself locked out, break your keys, or there's been a burglary. If so, you’ll need to call an emergency locksmith to get you into your house safely and securely, which will cost slightly more than a regular locksmith.

  • Emergency Call-Out Fee — This can reach up to £100 just for an initial consultation. Always check before agreeing to the call-out so you don't receive any unexpected charges.
  • Emergency Hourly Rate — Standard cost of about £90 per hour if you just need to get into your property. Whereas extra time and materials may be needed for a break-in or any damage to the door.
  • Outside of Working Hours — If you call at unsociable hours, such as weekends or weekdays 7pm to 6am, then you will be charged more. Likewise additional fees may apply on bank holidays and over the Christmas period.

How long does it take for an emergency locksmith to arrive?

This can differ depending on your area and personal circumstances, but this can typically be within an hour of calling if your locksmith lives nearby. This can be a really stressful experience for both parties so make sure you have all the correct details of locksmiths in your area and who is close to you.

Should I change the locks if I lose my keys?

It’s better to be safe than sorry, and if you are burgled using your own house key, your insurance will likely not pay out! A new lock is definitely the safest option, which should be requested as part of your emergency call-out.

What standards should I make sure my front door lock meets?

"That would depend on the lock on your front door. If it's a mortice lock, then you would be looking for a British standard lock. If a rim cylinder, then you want a 3*. With a euro cylinder, you would need 3* high-security locks."

Is a 2-3 lever mortice lock more secure and effective than a 5 lever mortice lock?

"A 2-3 lever lock is usually used on internal and bathroom doors while a 5 is a more secure lock used for front and rear doors.

A British standard 5 lever lock would be most effective and secure as it includes anti-burglary features such as a curtain, anti-pick notches, reinforced bolt, and additional plating to protect against drilling.

Insurance companies usually ask home owners to fit British standard lever locks to their front and rear door."

How Much Do Locksmiths Charge? (Labour Only)

The average labour costs and timeframe of a standard locksmith job are usually not too pricey. Generally, a locksmith will charge up to £80 per hour for a Monday to Friday 9 – 5 job.

However, if you hire an emergency locksmith at late hours or on weekends, then they can charge you a call-out fee of a minimum of £50 just for coming out.

Emergency locksmith jobs typically incur higher costs, with increased hourly rates and a tiered pricing structure based on the time of the emergency call.

How Long Does Changing a Lock Take?

Timescales can differ depending on the scale and difficulty of the job; however, in most cases, a standard lock changing job will take from between 30 minutes to 2 hours.

Emergency call outs can vary, but an initial consultation can take up to an hour, and more complicated jobs which require materials may be extended to the next day.

A locksmith can replace and upgrade your home’s locks. Why would your locks need changing or replacing? The most common reasons why new locks need to be fitted include:

  • Moving into a new home.
  • Current locks insufficient for insurance reasons.
  • Lost keys.
  • The existing lock is worn or faulty.

It is important to consider replacing all the locks in a property, especially when moving into a new home, to ensure comprehensive security.

So it is essential that you only deal with reputable and professional locksmiths who are vetted, inspected & background checked. The easiest way to do this is to use only MLA (Master Locksmiths Association), locksmiths.

What Impacts Lock Change Costs in the UK?

Below is a general outline of the different cost factors that you’ll encounter when changing your locks.

Emergency Call-out

If you’re ever in a situation where you’re locked out of your house, or your lock breaks and you’re stuck, then you’ll need to call an emergency locksmith to sort the job.

Material

The material costs include whichever lock choice is suited for your door. A budget lock cylinder will be cheaper (starting at £50), whereas a high quality and secure lock cylinders are more expensive, starting at £150 but can prove a saving in the long run, helping you avoid potential repairs at a later date.

Size of Job

How much it costs to change locks will vary depending on how many locks need doing and in the event of damage or a break in, the severity of the issue. For example a key broken inside the lock or any external damage that also needs fixing at the same time.

A standard lock change can take from 30 minutes, up to 2 hours and if you're having more than one lock changed then expect to be charged by the hour or quoted for the total job.

However, if you’ve rung for an emergency locksmith, then they may not have the right materials or parts for you and will take an extra day or two to order them in.

How much do locksmiths charge per hour in London?

"I would suggest an hourly rate between £60 and £80. We charge £55 for the first hour and £10 per 15 minutes thereafter. This is for work in the suburbs — rates in central London will be higher. Expect to pay more for out-of-hours services, weekends, and Bank Holidays.

Always get a quote before any work begins, if possible.

What Is Involved in Getting Your Locks Changed?

Changing your locks is usually a simple and stress-free job for any professional locksmith, with the work involved as follows:

  • Removing Previous Lock — The first two bolts will be detached before turning the plate assembly and removing the deadbolt lock assembly, after which the screws and deadbolt plate are also removed.
  • Changing Locks — Next, the new lock and deadbolt are fitted, including the mechanism and assembly plate. The doorknob is twisted to access the bolt holes, and the key assembly is then fastened.
  • Testing the Lock — The locksmith will lock and unlock the door with the key several times to check their work and ensure a smooth operation before clearing up any waste.

Can I Change Locks Myself?

There’s nothing to stop you from fitting your own locks, but this is not recommended for most unless you know exactly what size and type of door lock you need to keep the home secure and not invalidate your home insurance.

Incorrectly specified and/or fitted locks are useless when it comes to stopping criminals, so the best bet is to get advice from a Master locksmith to prevent any security issues.

If you decide to ignore the advice of the Police and consumer organisations and fit locks yourself – at least take advice from a locksmith on which locks to buy and make sure you fit them correctly following all the manufacturer’s instructions.

Will it make any difference to my insurance if locks are fitted by myself or a locksmith?

"It won't make a difference as long as the lock itself is an insurance approved lock."

Choosing a Lock

Deciding what type of lock you get may not even be up to you, as certain door makes will only fit with one lock. This is why it’s always essential to have a professional locksmith to change and fit new locks: they’ll know exactly what type of lock you need.

Below is a general outline of the most popular locks you can get and a few pros and cons.

5 Lever Mortice Deadlock Cost

Benefits of Changing Locks

If you’re unsure on whether you should be replacing or changing your locks, below are several benefits which may sway your decision.

Safer Home

In general, changing your locks from time to time will make your home safer. You should always change your locks when you first move into a new house, as you never know who had access to it before you moved in.

Deter Thieves

If you’re feeling uneasy from a burglary experience or have heard rumours of neighbourhood thieves, then changing or updating your locks to a more secure version can help deter thieves from targeting your home.

Peace of Mind

This can be for a whole host of reasons, such as if a flatmate or ex has moved out of your house, and you may be concerned that they’ve had an extra set of keys made. This is also applicable in workplaces; if an employee gets fired, you can never be sure who has access to your office.

Do I Need To Change My Locks?

Changing locks is an extremely common job which people will have to do several times throughout their life as a homeowner. Reasons differ from thieves, such as lost keys, locked out, old locks, area of the home, and updating to a more secure option.

Unlocking a locked door often involves a locksmith who uses non-destructive methods to minimise damage. The cost can vary based on the type of lock and door, with several factors influencing the overall price.

Sometimes, it may just be that your lock needs repairing; things to look out for include:

  • Damaged locks, ranging from unstable and loose keyholes to noticeable chips and scratches.
  • Defects, this can be detected if you’re struggling to open your door or having trouble unlocking it.
  • Older locks will typically need either repairing or replacing straight away when moving into a new home.

If you’re worried about the aesthetic of your doors and locks, then you may want to hire a contractor for a repair job if you notice any scuffs, scratches or marks.

Cost of Door Lock Removal

Removing a sole door lock by itself is typically uncommon — in most cases, you’ll have to replace the old lock with a new one. However, there may be times when landlords want to take locks off doors, or parents wish to access their children’s rooms.

In cases like this, a contractor can simply remove the lock and seal over the existing hole, taking no more than an hour for a single door and costing an average hourly rate of £50 to £60.

DIY enthusiasts can easily undertake this task if they have extensive knowledge of different types of locks. For a regular cylinder lock, you’ll need a Phillips head and flathead screwdriver, and an Allen wrench. Starting by removing the screws and spindle with both screwdrivers, then popping the cylinder out with your Allen wrench.

Lock Repair Costs

Lock repair costs can vary depending on the type of lock and the extent of the damage. Here are some approximate prices for common lock repairs:

  • Repairing a mortice lock: £55 – £80
  • Repairing a euro lock: £45 – £65
  • Repairing a upvc door lock: £75 – £100
  • Replacing a broken key: £90 – £120
  • Replacing a lost key: £100 – £150

Note: These approximate prices may vary depending on the locksmith and the specific job.

If a lock breaks, is it smarter to repair it or just get a replacement instead?

"It depends what type of lock it is. If it’s a mechanism lock inside your Upvc door then it can be repaired. But generally if it’s a faulty broken lock that keeps playing up, replacement is simpler and secure."

Locksmith Part Pricing

Locksmith part pricing can vary depending on the type of lock and the quality of the parts. Here are some approximate prices for common locksmith parts:

Part Avg. Cost
Rim cylinder £25 – £50
Traditional nightlatches £25 – £50

FAQs

What is a British Standard Lock?

BS3621 is a British Standard lock for typical locks fitted to doors; these locks are tried and tested to a specific level of theft-resistant security. British Standard locks have a ‘kite mark’ symbol, so homeowners and contractors know if their lock complies with BS3621.

What locks do I need to have in order to comply with my home insurance policy?

This differs from one policy to the next, so the best advice is to check your individual policy for the small print. But generally, most insurance companies want either a five-lever mortice deadlock rim automatic deadlatch complying with BS3621.

Can you repair all types of locks?

A lot of locks can be repaired rather than replaced and changed; however, you may want to weigh up the option that is best for you based on your specific lock. Most contractors will come out to your home to make an assessment and recommend whether they think you need a fix or replacement.

What is lock snapping?

Lock Snapping is a method which many thieves and burglars use to gain access to properties. This can be done by breaking the lock cylinder and jiggling the lock until it is pried open.

Anyone can learn to lock snap which is what makes this so worrying; however, it can be avoided by fitting an anti-snap euro cylinder lock onto your uPVC door.

What is the best lock choice for a wooden door?

Usually, the best lock for a wooden door is one which meets the requirements of a BS3621. This can be installed with a mortice deadlock and sash lock, and a night latch.

Always make sure that a qualified locksmith installs and replaces any locks within your house to adhere to the British Standard of safety.

Is it cheaper to rekey or replace a lock?

Rekeying is when pins are replaced inside an existing lock to take away any access of a previous key. This is useful when changing flatmates or after messy break-ups to avoid any potential unwanted entries. Some people would prefer to replace the lock all together as it can be easier and cheaper and offers more benefits.

However, not all locksmiths can replace your locks, and not all of them offer rekeying, so it all depends on your lock replacement research.
