The cost of changing locks can vary significantly depending on several factors. Here's a breakdown of the potential costs involved:
1. Locksmith Fees:
Hourly Rate: Locksmiths typically charge an hourly rate for their services, which can range from $50 to $100 per hour.
Service Fee: Some locksmiths may charge a flat service fee in addition to their hourly rate. This fee can cover the cost of travel and other expenses.
Emergency Fees: If you need a locksmith to change your locks outside of normal business hours or in an emergency situation, you can expect to pay higher rates. Emergency fees can range from $75 to $125 per hour, and there may be an additional trip charge of $100 to $150.
2. Lock Costs:
Type of Lock: The cost of the lock itself will depend on the type and brand. Basic doorknob locks can cost as little as $20, while high-security or smart locks can cost several hundred dollars.
Number of Locks: The total cost will also depend on the number of locks you need to change.
3. Additional Factors:
Door Type: The type of door you have can also affect the cost of changing locks. Some doors may require more specialized tools or techniques, which can increase the labor cost.
Complexity of Installation: If the installation is more complex, such as if you need to change the strike plate or reinforce the door frame, the cost will be higher.
Overall, you can expect to pay anywhere from $100 to $500 or more to change your locks, depending on the factors mentioned above.
Here are some tips to help you save money on changing your locks:
Get quotes from multiple locksmiths: Compare prices from several locksmiths in your area to find the best deal.
Consider changing the locks yourself: If you are comfortable with basic DIY projects, you may be able to save money by changing the locks yourself. However, it is important to make sure you have the necessary tools and knowledge to do the job properly.
Choose basic locks: If you are on a budget, you can save money by choosing basic doorknob locks instead of high-security or smart locks.
Change locks during normal business hours: You can avoid paying emergency fees by scheduling the work during normal business hours.

Antique and Specialty Furniture Locks on Cabinets, Armoires, Hutches and more
Antique and Specialty Furniture Locks
How Locksmiths Open and Make Keys for Antique Furniture
Antique furniture carries a unique sense of history, character, and elegance. Whether it is an inherited mahogany desk, a vintage wardrobe, a delicate curio cabinet, or an old cedar chest, these treasured pieces often feature intricate mechanical locks. However, time takes its toll: keys get lost during moves, mechanisms rust, and vintage drawers become permanently stuck shut. Restoring functionality to these specialty items requires a unique blend of historical appreciation and technical expertise in Antique Furniture Lock Repair & Key Making.
Unlike modern doors that use standardized cylinder locks, antique furniture typically utilizes lever locks or bit-key mechanisms. Opening a locked vintage piece without a key requires immense patience and specialized tools. A skilled locksmith uses a delicate technique known as lock impressioning. By inserting a blank metal key into the locked cylinder and applying gentle pressure, they can read the subtle marks left by the internal levers, allowing them to file down the blank until a brand-new, perfectly fitting skeleton key is crafted from scratch—all without damaging the delicate historical wood, brass, or iron around it.
Maintaining antique hardware also requires specialized care. Lubricating vintage cabinet locks with the wrong substances can attract dust and gum up the internal springs. Professional locksmiths can safely disassemble, clean, and restore old cabinet locks, preserving their historical value while ensuring they open smoothly for generations to come.

Male Chastity - Personal Security Protection that's Different
We originally posted the article below in January 2011 and it has gathered thousands of views online. The sellers have updated their product offerings in due course and we highly suggest checking out the source for their updated products.

What Is Your Preferred Door Hardware Color Finish?
What Is Your Preferred Door Hardware Finish?
What is your preferred door hardware color finish? We have been taking a long look through our invoices over the last 15 years and determined the most popular and preferred color finish selections from our vast list of clients.The stock photo above is an image of a piece of nickel. We include it here because of the sudden rise in the market price of nickel ore, just in the last 2 days. We suspect there are obvious reasons for this sudden spike, given the political and economic upheavals our world is currently experiencing, but this story made me think about the most common request for color finishes of door hardware, knobs, deadbolts, lever entrance sets. thumbpress entrance locksets, hinges, peepholes, door sweeps, blocker plates, wrap-arounds etc, among some of the products we have sold, serviced and installed over the years.
The common finishes in the market in the USA and other countries around the world are pretty much similar even though some places choose varying preferences, which could be regional among other reasons.
I'm sure people across the industry and around the world, decorators, interior and exterior designers, locksmiths, builders, retailers etc would enjoy understanding why some color selections are made over others and if you would like to share your preferred color finish choices in the comments below that'd be great.
According to our deep dive into our books, the preferred door hardware color finishes are topped by the Satin Nickel choice.
Antique Brass comes a distant second followed closely by polished brass, with venetian bronze and florentine bronze bringing up the rear. Black is finding more traction in recent years but is still farther down the list of preferences.
We have been representing a few manufacturers over the last 15 years, including Serrature Meroni products, Assa-Abloy Lockwood, Schlage, Kwikset, Weslock, Hooply, to name a few.
Many contractors and retailers will offer a variety of color options to fit the unique tastes of clients. Simply ask your chosen contractor if your desired door hardware color finish is available.

Contact-Less User Interfaces Are Becoming A Part Of Our New Future - Part 2
The impact that voice-recognition technology is having on our daily lives, is becoming more prevalent, given the current pandemic and quantity of smart-speakers currently available.
The above video we shared in a post we wrote almost a year ago and while it is somewhat comical in it's presentation, it does perhaps highlight a potential future that awaits us.
The article we wrote last year, portends that perhaps there are issues with smart-speaker technology today that we are yet to perfect. Given the current times, I suggest that the uptake of more voice recognition technologies may become an even greater part of our lives, that our article did not recognize at the time.
In March 2018, we also wrote about the integration of Amazon Alexa into new housing constructions in Sydney Australia. Perhaps this kind of technology is not too distant from us any longer?
I'm curious to know other people opinions about this subject.
Contact-Less User Interfaces Are Becoming A Part Of Our New Future - Part 1
We decided to share a new post to discuss some contact-less options that already exist in today's world and articles that we have written over the last 10 years or so.
Voice control is one area that we have embraced in recent years with the advent of Google Voice, Home, Amazon Alexa, Echo etc among other offerings.
Below find a number of articles that we have written, that provide some interesting reading about some of the options already available to us. Some of the products listed below do not exist anymore but talented researchers are constantly creating new and improved products that might help us progress through this new world...

Verroo - Unique Security Products For The Worlds New Normal Amid Coronavirus Pandemic
At this lecture he gave a rather interesting expose into the security and perception of security of Knox Boxes, which are used and required predominantly by fire departments across the USA to allow authorized first responders to gain access to private and public dwellings without the need to employ destructive entry methods.
The video is about 20 minutes long and may be of interest to locksmiths. security industry technicians, sales people, maintenance technicians, first responders, home owners, apartment complex managers, basically anyone who might see or have these type of key boxes on or near their properties.
It is especially interesting when you consider the security offerings by various vendors concerned more with selling you their products as opposed to offering you a system that actually offers to protect and secure your property for real. (For some unscrupulous vendors, it's not about your security protection - it's only about profits)
We have written about some of the subjects he talks about in the video....

Further to this conversation is my recently acquired knowledge about an Australian company that is the merge between KJ Ross Security Locks, Marget Engineering and Direct Connections in 2015. That new company is called RMD Innovations (you can see their site in the source below).
KJ Ross, I have personally known for about 35 years now, having worked with their safe lock products, their Rosslinear Battery Operated Electric Strike and other lines in their specialty ranges.
RMD have now created significantly improved products for the high security market that update the older Rosslinear Strike (as seen above) and also have begun offering some additional products including a battery-operated strike for rim locks, panic exit devices. standard mortise and cylindrical entry lock-sets. among other products





I am especially interested in these updated product offerings, given the current predicament the world is experiencing with the Coronavirus Pandemic, that has dramatically altered our states of life.

Coronavirus - Add To List Of Recent Deadly Virus' Able To Kill Us
The news affecting the entire planet in recent months seems to be mostly about the Coronavirus, infecting thousands of people around the world
Below you can see a number of articles, we have written in recent years, about the increase in the quantity of deadly infections that have arrived in recent times and potential products that can mitigate the spread of diseases and virus'.

Ebola Scare - Preventing The Spread Of This And Other Contagious Diseases.
The disease has been surfacing and spreading across Northern Africa for the past couple of years and has started to make it's way to Europe and America with cases being reported in Spain, Greece and Dallas Texas.
A few years ago, the nasty Avian Flu from Asia commonly referred to as H1N1 was the planets last massive virus to affect numerous victims across the world, that got the attention of the media and Centers for Disease Control.
There are many media sources that have been reporting on methods to minimize the spread of this fatal virus, but so far the only cure is said to be a product called Zmapp, a drug developed in the USA to combat the disease.
Serrature Meroni, the Italian manufacturer of leading nouveau door handles and entry products introduced their Anti-Bacterial range of door knobs, about 7 years ago. The product uses an especially formed handle that dissipates or bounces microbes and bacteria away from the door handle, preventing transferrence of these "nasties" between people who naturally would touch the entry door handle to enter or exit a dwelling.
Prevention is often said to be better than cure, because it mitigates the spread of a disease before it can affect large populations.
The Serrature Meroni Combina is the logical choice for any public amenity, hospital, medical office, clean room, laboratory or even educational facility, that might decide that the protection of their staff and guests is of vital importance to their business.The handles are available in limited colors (which has something to do with the Anti-Bacterial properties) and enables all users, even the physically challenged, to easily operate the door handles, free from worry of contracting or spreading diseases.
Serrature Meroni are also producing a similar product using their top-end Pigio line of handles.
Pigio is the highly sought after, push-pull handle system that modern interior designers are calling upon to add flair and creativity to interior architectural door hardware. A sace that is inviting many new designers into the industry.
Pigio 1 are a large (relative) body handle with a rounded push-pull handle.
Pigio 2 are a stylish oval shaped handle.
Pigio 3 are the top end of the Pigio lineup and use superior metals to produce the finest push-pull handles of their kind.
The color ranges are impressive and the small footprint makes these locks a beautiful yet functional adornment for doors. Using these products, allows for ADA compliance, meaning anyone can operate the handles easily, while providing a sightly and easy to use product that keeps you safe, secure and free from diseases.
We cant be too vigilant now, can we?

Measles Makes A Resurgence at Disneyland - But Meroni Has You Covered
Measles were supposedly wiped out by vaccines in the early 1970's but this new strain appears to be a mutated version of the all too common childhood disease.
With the regular news reports about viscious diseases and virus' popping up all over the world and in significantly increasing numbers, it has become a vital and important factor when considering protecting people in public buildings, dwellings even at home.
Diseases spread easily among children especially, due to their immune systems not having achieved sufficient maturity to ward off some spreadable virus'.
Meroni have been at the forefront of Anti-bacterial handles for many years and their unique handle products like the Combina and Pigio offerings, provide care facilities, schools, hospitals and laboratories, all across the world with handles that minimize and mitigate the spread of shareable diseases.
Competitively priced and available to order, the extra special coating on the hardware is tested to European standards that are often considered significantly higher than the standards issued in the USA.
This is a picture of the Combina Anti-Bacterial Handle.
Available in passage, privacy and entrance versions, the color of the handle is an important attribute in the production of these anti-bacterial handles
This allows for a simple to operate, good looking handle that can be used on just about any door that offers ease of use by physically challenged and mitigates the spread of contagious diseases simultaneously.
Any of the unique range of Meroni hardware, make operation by arthritis sufferers much simpler than conventional handle hardware.
Many arthritis sufferers are challenged to clench their fist, which makes operating the simple door handle a task indeed. Not anymore, thanks to the fabulous Meroni range of handlesets.

To become a reseller of the product, contact us to arrange pricing.

5 reasons to stop using antibacterial soap
To summarize. the FDA discovered that after a decades long investigation, the benefits derived from this multi-billion dollar industry, do not significantly add value to our lives, more than normal soap and water.
I meet people regularly who swear by their practise of using some alcohol based antibacterial soaps, hoping to minimize their own exposure to the easy transference of bacteria and virus'.
With this 42 year study finally releasing their results, concerned users are realizing that common used door knobs, that multiple people touch daily have been a harbinger of diseases that are too easily transferred.
That is of course until they learn about the Serrature Meroni range of Combina and Pigio range of push/pull entry levers and knobs, that are specifically designed with anti-microbial surfaces that minimize the spread of colds and flu.
We are the North American distributors of the fabulous Nouveau and Ultra-Modern door entry products made by the highly respected European (Italian) manufacturer Serrature Meroni.
We maintain a relatively large inventory, in multiple color options of Nova, Forma, Combina and Pigio (1, 2 & 3) door hardware.
We will showcase some special quantities of Meroni Nova, passage, privacy and entry handlesets, in large quantaties and diverse color options.

Already Deadly in Africa, Could Ebola Hit America Next?
The article in the source below, gives an example of how this deadly disease can spread so easily and because the world is quickly becoming too small for deadly diseases like this to be contained easily within borders.
Apparently an outbreak of Ebola occurred in a Washington DC suburb in the last few weeks. Luckily it was contained quickly but the issues about deadly virus' continue to be front and center news that potentially can affect all of us.
The spread of disease is all too common today, as the last few years have shown us with H1N1 and Avian Flu and H4N1 being the most well known and talked about.
Minimizing potential disease infections and spread is a very serious challenge for medical centers, hospitals, aged care centers, hospices, hotel, schools, child care centers, gymnasiums, swimming pools and almost any public building. Many of the businesses and institutions mentioned employ quality janitorial staff who expertly maintain and clean railings, doors, bathrooms, handles and shared public facilities.
But many handles can still transfer deadly bacteria that can contain germs of the kind that spread diseases very easily and are used by very many patrons of establishments between times that the janitorial staff perform their cleaning routines. It is not possible to prevent the transfer of microbial and infection borne diseases all day every day, is it?
Well, thanks to the fine Italian manufacturer Serrature Meroni, it is. Meroni have been at the forefront of handle design for many years and continue to produce award winning designs. Their Combina and Pigio handles are especially designed with anti-bacterial properties that directly disperse infectious bacteria and other potentially harmful virus' .
Any facilities manager realizes just how important the safety and health of staff, patients, visitors, residents and children is to the efficient and continued running and management of institutions as mentioned above.
We at Master Key Systems America LLC appreciate that the health and well being of all peoples is vital and important to continued happy existence and are proud to offer the fabulous Meroni Anti-Bacterial handles to the the North American market.
