    Timescales can differ depending on the scale and difficulty of the job; however, in most cases, a standard lock changing job will take between 1-2 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.

    Cost Factors of Getting Your Locks Changed

    A variety of factors can affect the cost of a lock changing job, as well as increasing the amount of time it takes to be completed. Below is a general outline of the different cost factors that you’ll occur when changing your locks.

    Emergency Call-out

    Emergency call-out charges can massively impact the amount you spend on changing your locks. 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.

    Normal working hours which include Monday to Friday from 9-5 and can cost about £50 for a call-out charge. However, if you call during the hours of 6pm to 8 am, then their call-out charge can raise itself to £100 due to inconvenience and personal time.


    The material costs include whichever lock choice is suited for your door. As to be expected, a budget lock cylinder will be cheaper starting at £50, whereas a better quality and secure lock cylinder will be more expensive, starting at £150.

    Although it may seem easier to go for the budget option, a higher quality lock will serve you better in the long run and will help you avoid potential repair and maintenance costs.

    Size of Job

    The size of each job will change depending on how many locks need changing and the severity of the issue, e.g. key broken inside or lock being damaged. A standard lock changing job for several doors within your house can take between 2-3 hours for around £50 for the first hour, and an extra £25 for every extra hour.

    However, if you’ve rang 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.

    What's Involved in Getting Your Locks Changed?

    Changing your locks is usually a simple and stress-free job for any professional locksmith.

    Below is a guide to what a typical replace and installation job will look like when being performed by a tradesman.

    Removing Previous Lock

    After an initial consultation and agreeing on a quote with your locksmith, they will start the job by removing the door’s lock and deadbolts.

    The first two bolts will be detached first before turning the plate assembly and removing the deadbolt lock assembly. After this, they will detach the screws which hold the deadbolt plate.


    Changing Lock

    Next, they will fit the new lock and deadbolt, installing the mechanism for the lock before turning the assembly plate, so it fits to the top. Next, they will twist the doorknob to view the holes in the bolt, fastening the key assembly securely.

    Secure and Test

    Finally, your locksmith will triple test your door after it’s been connected into place safely and tight, making sure to lock and unlock the key several times. After they’re confident with the product, your door will be wiped, cleaned and cleared of any waste.

    Can I Change Locks Myself?

    There’s nothing to stop you 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.

    You may want to lessen your prices when pricing up the cost of changing a lock, but you and your family’s safety come first. In addition, do you know how to fit the locks properly, so criminals can’t easily bypass them?

    Lock snapping is a standard method used to gain entry by burglars, do you know what this is and how to prevent it? Lock snapping is a way to get past some cylinder locks which are prone to it, but a Master Locksmith will be able to give advice on fitting the correct standard of Euro Cylinder lock to prevent lock snapping!


    There is a big list of standards that relate to locks including Kitemark, PAS3621, EN1303, BS3621, SS312 Diamond, BS8621, BS10621, TS0071 etc. – how is anyone expected to know what standards are required and when?

    Your property keeps your family and possessions safe and secure, do you really want to compromise that with a spot of DIY just to save a few quid?

    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.

    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 because they’ll know exactly what type of lock you need.

    Building Regulations & Planning Permission for Changing Locks

    It is incredible that something as security-sensitive as the UK Locksmith industry is currently totally unregulated! This lack of protection under the law means that anyone can quite legally operate as a Locksmith even if they have absolutely no experience.

    In fact, someone could get out of prison for burglary one day, then set up shop as a locksmith the next! This, unfortunately, means that there is the potential for unscrupulous people to take advantage of the lack of laws surrounding the security industry.

    Locksmiths you find advertising online and in local directories could be completely unqualified with no criminal records check, they could even be professional burglars!

    To find a genuine locksmith, someone with training, experience and integrity, you need to look towards respected trade organisations such as the Master Locksmith Association. This is the main Governing Body for the Locksmith Industry and is recommended by various Police Forces around the UK.

    The Master Locksmith Association (MLA) has a strict vetting procedure for their members and only qualified. Experienced locksmiths can become affiliated Master Locksmiths that are CRB checked and regularly inspected to check on their business practices.

    You should always check the small print on your home insurance policy to make sure your locks are up to standard, or at least to advise the locksmith what type of locks will be suitable.

    However, decent locksmiths should be well aware of the type of locks stipulated by insurance companies and will be able to help you make the house secure and keep your insurers happy at the same time!

    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, lost keys, locked out, old locks, area of the home, and updating to a more secure option.


    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; this is a give in.

    Interference, 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.

    Emergency Locksmith Cost

    There may be an occasion where you find yourself locked out, break your keys or God forbid, as a victim of a potential 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.

    The fast response time means the labour costs can be around £90 for call-out costs without labour and materials. Below goes into more detail about how different aspects can affect your emergency locksmith costs.

    Type of Emergency

    The type of emergency can alter the cost of an emergency locksmith. It’ll be a standard cost of about £90 per hour for a lost key/locksmith to let you in, as opposed to added costs of extra time and materials needed for a break-in/damage to the door.


    The time you call for an emergency locksmith can massively change up your cost factors; if you call at unsociable hours such as weekends or weekdays from 7 pm to 6 am, then you will be charged more. You’ll also receive additional charges around bank holidays and Christmas, with working hours hiking up to £120 plus VAT.

    Call Out Fee

    A lot of emergency locksmiths will charge you a fee just for coming out. Their call out fee can reach up too £100 just for an initial consultation. Always make sure to check prior to picking a locksmith if they charge this fee.

    Cost of Removing a Door Lock

    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-£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.

    Hiring a Locksmith Checklist

    The Master Locksmiths Association scheme means all their locksmiths have been vetted and they are regularly inspected and are qualified locksmiths with proof of competence.

    There are other organisations which locksmiths can belong to. Still, some are unscrupulous entities which simply offer accreditation by post for the payment of a small fee with no checks whatsoever!

    So the locksmith gets to add an official-looking logo to advertising which helps to convince customers they are competent and reliable - but this is often far from the case!


    So stick with MLA approved locksmiths wherever possible. To gather quotes easily from up to three local locksmiths, you can use the free system on, simply enter brief details about the job then we will put you in touch with local tradespeople to provide quotes and further assistance.

    Below is a checklist to consider when hiring a contractor for changing a lock and checking locksmith near me prices.

    • Make sure your locksmith is MLA approved and has the correct qualifications for the job.
    • Seek out a few different options and ensure you ask for a handful of quotes from locksmiths before settling on one company/tradesman. Even if you think you have a good deal straight away, you should always weigh up other options.
    • Double-check that your locksmith is authorised to change your locks and has completed similar jobs to this before. Always ask for references and pictures from their previous clients.
    • Always put a written agreement with your locksmith out before any work takes place. This will ensure you have a clear outline of the job specification and what services will be included in their quote.
    • Always make sure that your tradesperson is insured and offers a guarantee for their work, as well as being registered with a reputable trade body.

    Last but not least, remember to ask for a receipt or payment confirmation to protect you against possible future disputes.


    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.
    Should I change the locks when I move home?
    There is no need for a lock change on your old home when you move, but you should definitely change the locks on your new house when you move in as a priority! When you get the keys to a new property, you have no idea how many keys already exist for those locks, or who has a set of keys.

    Don’t leave getting new locks/keys until after you have moved in and settled, as burglars love to rob homes when the new owners are still in the process of moving in and have left lots of valuables in boxes!
    Should I change the locks if I lose my keys?
    Definitely. 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.
    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.
    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.
    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, whereas not all of them offer rekeying, so it all depends on your lock replacement research.
