Upgrading Your High Security Door Locks
When you want to make sure your home feels genuinely secure, you need an expert in high-security locks. At Lock & Key Sheffield, we have a team of accredited Master Locksmiths who know locks like the back of their hands!


Are High-Security Locks Worthwhile?
Absolutely – we know the peace of mind that our clients enjoy when they invest in high-security locks in Sheffield. They know then that their home is resistant to typical break-in and forced entry methods, from physical force to sawing, drilling, and lockpicking. With high-security locks on your home or your place of business, you know that you are much less likely to become a victim of a break-in; only the best can break through the high-security locks we fit!
That means you have much less worry in the back of your mind that you could be a valid target for such a criminal enterprise. Criminals always find ways around security systems, and what was once vaunted and modern can become outdated very quickly. Our expert local locksmith will make sure you get locks that are of the best standard for modern best practice and British standards.
Your Local Locksmith in Sheffield – Keeping Homes Safe, Lock by Lock




What Makes a Door Lock High-Security?
As the name implies, high-security locks offer a more robust method of entry prevention and locking than you would get with normal lock types. The high-security locks that we work with in Sheffield make sure to meet all British Standards expectations, meaning you will meet insurance policy requirements. Generally, the high-security locks that our experts install in Sheffield offer:
Anti-Snap Protection
Stop your doors from being victims of one of the most effective entry methods in the UK today; all of our high-security locks are snap resistant.
Drill and Pick Resistance
Picking a lock is a matter of patience and skill; with high-security locks, only the most patient thieves will continue to try to break in. By using complex components, we make sure most lockpicking methods are made obsolete.
Key Duplication Security
Are you worried that someone might clone the key to your doors? Our high-security locks come with duplication protections to limit that risk.
Bump-Proof Technology
Lock bumping is a common problem, just like lock snapping is; even skill-free criminals can learn lock bumping. We make sure that such methods are far less likely to work on your doors.
Additional Reinforcement
Another benefit of our high-security locks is that they are protected against typical entry methods like lock sawing and drilling, as well as all of the above techniques.
Whatever the time, day or night, if you have a problem with your locks, we can help. We operate a 24/7 service across the Sheffield and surrounding area, providing locksmithing solutions to both residential and commercial customers.




Protect Your Property’s Security with Anti-Snap Locks
Lock snapping is one of the most commonly used methods for criminal entry not only in Sheffield but across the whole of the UK. It does not take a specialist either; you can learn lock snapping in minutes. It only takes seconds to carry out, too, meaning that the best resistance to lock snapping is to have high-security locks that prevent this kind of entry. With our locks, you have locks which make lock snapping almost impossible to carry out!
Does Your Home or Business in Sheffield Require High-Security Locks
If you want genuine peace of mind, there is no better way to create that kind of harmony than by installing high-security locks. These locks are up-to-date with British Standards, meaning they secure your home or business from most forms of criminal entry. This includes regularly used methods, such as lock snapping, which remains worryingly common in Sheffield.
With the locks we install, you get protection from all of the most regularly used break-in techniques that UK criminals use. Only the most skilled thieves would have a chance of breaking through your newly fitted locks, and they would make a lot of noise and bring a lot of attention when doing so. Prevention is always the best form of stopping the risk of being a victim. With high-security locks, you have locks in place that make illegal entry almost impossible to achieve!
How to Recognise Anti-Snap Locks?
The easiest way to know if you have anti-snap locks (or other high-security lock types) is to look for the Kitemark symbol on your door. The Kitemark should have a three-star mark above the Kitemark, too, meaning they are 100% anti-snap secured. If you are unsure, call us for a professional appraisal!
