Anti-Snap Locks
How Anti-Snap Locks Secure Your Home
Lock snapping is one of the most common and effective burglary methods used by criminals today. It exploits a critical design flaw found in standard euro cylinder locks — allowing intruders to snap the lock in half and quickly bypass the entire multi-point locking system on your door.
This method is fast, quiet, and devastatingly simple — often taking just seconds to carry out. Many homeowners only realise they’ve been burgled when they wake up in the morning to find their valuables gone and their car missing.
Lock snapping first appeared outside the West Midlands but has now become widespread across the UK. Based on our experience — and that of other locksmiths — it is now alarmingly common in Solihull, Sutton Coldfield, and surrounding areas.
The issue has become so serious that local police are now routinely advising residents to upgrade to anti-snap locks for added protection.
Certification Matters
What Are Anti-Snap Locks?
Anti-snap locks are specially designed to protect against this specific type of attack. These locks use ‘sacrificial sections’ — parts of the lock that are meant to break off if force is applied, without compromising the critical internal mechanisms of the lock.
To ensure your security, it’s essential to choose locks that are independently tested and certified to resist snapping — such as those with Sold Secure Diamond Standard or TS007 3-Star rating.
However, not all so-called anti-snap locks are equal. Some cheaper models offer little or no protection, snapping just as easily as basic euro cylinders.
Some anti-snap locks also include key code protection, meaning only authorised users can obtain additional keys. These may require a unique security card or code to be presented at the time of cutting.
Not all high-security locks offer this feature — so if key control is important to you, we can advise on the most suitable options for your needs.

What Makes Sold Secure Diamond Locks Superior?
At CraftLock, we recommend locks that meet the Sold Secure Diamond Standard — widely regarded as the toughest and most comprehensive security test available.
These premium locks include:
- Sacrificial segments to stall an attack
- Numerous hardened metal anti-drill protections
- Internal locking mechanisms that create an impenetrable barrier
- Optional key copy protection systems via a unique security card or code
They offer the highest level of resistance not only to snapping, but also to drilling, picking, bumping, and other forms of attack.

Many older high-security locks, even those with British Standard Kitemarks, focus on protecting against drilling and picking — but don’t include any protection against snapping.
For true snap resistance, you should look for locks that meet specific modern standards, such as: TS007 3-Star Standard (Door Hardware Federation) and
Sold Secure Diamond Standard (Master Locksmiths Association). These certifications ensure that your lock has been tested under real-world burglary conditions — and will hold up when it matters most.

I would highly recommend Ewan and his services. He was efficient and reliable. He accurately quoted me on the phone before arriving, without me having to ask. He turned up within 40 minutes of my call and managed to access my property within minutes and changed the entire lock within an hour. He was polite and professional & sent over aftercare advice & told me to call him if we needed any further help. Fantastic, high quality service delivered.

I contacted Ewan when my door handle suddenly failed. He was extremely helpful and responsive with a thoroughly professional approach. His advice helped me resolve the issue myself without the need for a visit. Very impressed!

So impressed - Ewan called me for details about the job, after I sent photos he suggested a quick fix I could try to fix my mortice lock, which worked. He saved me money and demonstrated his experience. I suspect I'll eventually have to replace the lock anyway, I'll definitely be calling Ewan then.

Excellent service. Ewan is very professional, reliable and competent locksmith. I used his service twice and would definitely use again and recommend. He made my home secure. You get a date, time and cost before he arrives. Very reliable.

Ewan is excellent at his work and I can't fault his craftmanship at all. I got 3 quotes from different locksmiths and what made me choose Craftlock was they were the lowest quote (no vat so 20% cheaper for a start, and a small company so no large overheads like call centres etc.), but also because he was so polite and friendly. When he arrived to do the job, he was polite, clean in his work, and thorough! He not only fixed my lock but also repaired the door setting so it won't happen again. I can 100% recommend Ewan from Craftlock Ltd, trustworthy and excellent at his trade.

From Ewan Clerk's initial visit to assess the job, until completion of the work, he was the complete professional. Easy to get on with, meticulous in his workmanship and a member of the Master Locksmith's Association. Nothing was too much trouble, and he was fully compliant with Covid-19 safety requirements. I now carry Ewan's business card with me at all times, safe in the knowledge that should any emergency with a lock occur in the future, help is at hand. I thoroughly recommend Ewan Clerk and Craftlock Ltd.

Ewan originally came to replace a lock out of hours to my property after an attempted break in. He then returned a few days later to replace some other locks for anti snap ones. He did an amazing job and is extremely knowledgeable. I would not hesitate in using his services again and recommending him to friends and family.
Customer in Sutton Coldfield

I found myself locked out recently. Ewan arrived as soon as he could to deal with the broken lock, even though it was a tricky job after a full day's work, and a dark, cold evening. As ever, a very reasonable price and polite service. Thoroughly recommended.

This is the second time Ewan has helped with lock replacement. Again, his communication is timely/responsive, both for the quotation, and up to and beyond completion of the work. His work was again of an exceptionally high standard, he was very tidy, and the cost was exactly as quoted. I asked for some additional advice and quotes, which Ewan provided (in respect of advice) on site, and confirmed in writing with quote the next day. As before, I was assured that he is very much thinking of my security needs, and did not suggest work that he did not believe was needed.
Customer in Kings Heath

Ewan replaced four external locks on our property shortly after we moved in. He was able to book us in within one day of our call to him. He was very tidy, polite, and took the time to explain to us how the new locks worked in addition to some slight amendments that he made to our front door. We will certainly use him again in the future if required.

Excellent response time after discovering an attempted break-in on a barely working door. This has now been repaired and works like it should. Wish I'd had it done years ago. Ewan was very informative and emailed a detailed quote with various options. No hidden charges or nasty surprises.

Craftlock were recommended by my alarm company. I was completely satisfied with the service we received. Ewan was so helpful in advising us of the best lock to use, but not in a pushy way. He is a professional, who knows his trade and wants to give good old fashioned customer service.
