Understanding Lock Prices

Whenever you think about improving the security of your home, the cost comes to mind. Your home is the biggest thing you will ever buy, so it’s natural to want to protect it. It’s up to you what type and how many locks you purchase for your house, there is a wide variety to choose from, so it can be confusing trying to work out what’s best for you and your home.

This means many home owners will take to Google to ask how much new locks should cost. Does a cheap lock mean sub-par security? But on the other hand does an expensive lock really mean you are getting a better quality lock? Here at the NGCL we want to help you answer those questions, as well as looking at what effects the price of a lock.

What Influences the Cost of Door Locks?

The Type of Door Lock

There are several types of door locks, the most common are:

  • Mortice Lock
  • Euro Lock
  • Rim Lock
  • Padlock
  • Yale Type Lock (Night latch)

Not all door locks are the same and when it comes to researching the cost of a new lock, you need to take in to consideration what type of lock is being purchased. Whether you need an external door lock, internal door lock or smart lock, prices can vary. Once you know if you are looking for an external or internal lock, there are more categories to think about; do you need a British Standard, Anti-snap, Mortice, or Euro Cylinder? Mortice locks are traditionally used on wooden doors, whereas Euro Cylinders are used on uPVC. So what your door is made of will make your choice for you.

Door Lock Standards

The standard of a door lock is a measure of the quality and security of the lock. The various lock standards are used to test the strength and reliability of the door lock. To be given a certain standard, a lock must be able to pass various tests that prove their strength and longevity. British Standard sets a benchmark for quality goods and services.


This standard is aimed at protecting cylinder locks against all known methods of forced entry. Any cylinders or hardware solutions that meet the requirements are marked in correlation with the star rating scheme.

 BS 3621 and BS 8621

This series was set to provide a national performance standard for single point locks that ensure a minimum specification deemed to provide suitable protection for external doors.

This is regulated by the BSI (British Standards). The BSI has a Royal Charter that grants them the authority to prepare, revise, alter and amend the standards as experience and circumstances require. A lock with British Standard kite mark is guaranteed to meet the minimum performance for locks and cylinders on internal or external doors set by the police service. A door lock with a British Standard kite mark will cost more than an untested lock, but you will be paying for the peace of mind that this lock will secure your home.

There is a trend of higher standard locks having a higher price tag. This is because the higher the standard the longer the lock will last and keep you more secure than lower standard locks. In this instance, choosing to spend less on your home security may be detrimental in the long run, as the cost of a break-in will be significantly higher than the cost of a high standard lock.

Installation of your Lock

Unfortunately, just buying a replacement door lock isn’t enough. You will need to install it as well. You might be tempted to install the lock yourself to save money. However, unless you are a professional Locksmith we would advise against it.

Modern uPVC doors are very complicated and contain a lot of mechanisms, so you may struggle to install the lock correctly which will leave your security weakened and more susceptible to an attack. Even if you have the DIY skills to fit the locks yourself, by doing so you may be breaching the terms of your home insurance. This would mean that if you did suffer a break in, and you fitted the locks yourself, your insurance company might not pay out.

The cost of a Locksmith will depend on a few factors; how many locks you need changing, what type of door you have and what equipment is needed. Most Locksmiths will be able to install one new lock within an hour, however if you have just moved and need multiple locks replacing it could be longer and therefore cost more. The price of a Locksmith may also be affected if you call them out for an emergency as rapid response and unsociable hours mean a Locksmith may charge more. You can’t help your lock breaking but if it is a planned job then you may try to keep it in work hours on a weekday to keep the price down.

Brand of Lock

As with almost every product on the market, you will find it is available in several brands. You may have heard of some of the big lock brands; Yale, Abloy, Mul-T-Lock etc. Big brands do come with certain benefits; guarantees, customer service and a long history of manufacturing locks, amongst other things, but they do come with a bigger price tag.

There are some lock brands that are endorsed by Locksmiths and experts that offer a high amount of security whereas there are big lock brands that homeowners are warned against as the security of the product isn’t relative to the price. Branding can be a very confusing as popularity and brand can often be confused with quality when this isn’t always the case.

Companies like Yale have been around for 100’s of years and most Locksmiths train by using the most common brands. If you buy a lock that is unbranded or an obscure brand, there is a risk that a Locksmith may not be able to fit it.
