“Chris kept me informed via WhatsApp with what was going on (that he had ordered the parts, that they had arrived and that he was on his way) and he arrived on time. Within an hour he had completed the work to a very high standard. I would highly recommend him. Thank you so much!”

“Chris was very helpful, called him on a Thursday night and managed to get an appointment booked for Friday. He was very efficient, and professional and ensured that the problem was sorted. Also recommended other professionals for other bits I needed sorting out around the house. Can not recommend Chris enough due to fast and efficient service at a very high quality.”

“A very positive experience. Chris was able to attend on the day I contacted him and gave me a clear idea of the likely cost of the repair in advance.Great communication and I felt that he only did what was needed rather than trying to oversell. Friendly service and good value too.”

“We recently engaged Chris to change locks at our new home and the experience couldn't have been any better. Chris was very friendly, polite and informative and though the job turned out to be much more complicated than anticipated he truly went the extra mile to get things sorted. Highly recommended!”

“Had just moved house so wanted to get the locks changed. Chris was absolutely amazing, really friendly and helpful. He changed all my locks very efficiently and even went the extra mile to look at the garage door and windows. Excellent price as well, especially considering I got 5 keys for each lock. He even gave us some advice on nice places to visit since we are new to the area. Would highly recommend him.”

“Absolute legend Chris was! We were locked out with our kids which is not a fun situation to be in, but Chris came in and immediately improved all our moods thinking it's gonna be okay. We had a particularly harder job since we were "smart" enough to keep our keys in the lock! This was night and day from my last experience with a locksmith who just wanted to drill the lock and make me pay unnecessary costs.”

“Chris was excellent and replaced my locks the very same day. He also gave me some advice and helped me with some other issues I'd been having with some internal doors. I highly recommend him if you need a locksmith.”

Typically, we can provide a fixed price over the phone in advance. This approach ensures transparent pricing, so customers are fully aware of the cost before work begins. Our pricing is based on the job rather than an hourly rate. For issues like a failed multipoint locking mechanism, we offer an estimated price range from the best to worst-case scenario, as identifying the exact fault requires an on-site inspection.

A high-security euro cylinder with a 3* TS007 rating offers maximum protection against forced entry. These locks are specifically designed to resist common attack methods such as snapping, drilling, plug-extraction, picking, and bumping. Installing one significantly enhances your security, giving you confidence that your home or business is well-protected.

The handle’s external section features a hardened steel or reinforced guard that shields the euro cylinder, making it much harder for intruders to access or snap the lock.

 

Anti-Drill and Anti-Grip Features:
Many handles include a rotating disc to protect the cylinder face from drilling, along with a chamfered backplate to resist gripping tools such as mole grips.

 

Reinforced Construction:
These handles are built with strengthened backplates, often reinforced with concealed steel, and fitted with hardened steel screws to provide extra durability and resistance to force.

 

TS007 Accreditation:
Each handle is tested to the TS007:2012 standard and has achieved a two-star BSI Kitemark, ensuring verified security performance.

Unfortunately, we do not offer an auto locksmith service at this time. However, we would be more than happy to recommend a reputable local auto locksmith if needed.

In the UK, insurance-approved locks must meet British Standards for security. The most common type is the BS3621 lock, typically found in mortice deadlocks and rim locks, requiring a key for operation on both sides.

For emergency escape situations, BS8621 locks allow keyless exit from the inside, making them suitable for flats and shared accommodations (HMO). BS10621 locks are similar but only lock/unlock externally with a key, restricting inside access.

For uPVC and composite doors, multipoint locks (PAS 3621 or TS007) provide high security through multiple locking points. Euro cylinder locks must meet the TS007 standard, with a 3-star rating or a combination of a 1-star cylinder and a 2-star handle to prevent lock snapping.

Smart locks can be insurance-approved if they comply with BS EN 15684 or have Secured by Design (SBD) accreditation, often needing a secondary mechanical lock for full compliance. Additionally, key-operated window locks that meet BS7950 or PAS 24 are required for accessible windows.

When booking a locksmith, following these practices ensures a secure and hassle-free experience. Begin by researching trustworthy local locksmiths, reading customer reviews and recommendations, and verifying their credentials, such as licenses, insurance, and certifications.

 

Always request a price estimate upfront to avoid hidden fees and confirm whether additional charges apply for emergency or out-of-hours services. Be cautious of unusually low quotes, as they could signal scams or hidden fees.

 

Clearly explaining your lock issue when booking a locksmith helps the locksmith prepare properly and reduces the chance of delays. Once you’ve found a trustworthy locksmith, keep their contact details handy for any future emergencies.
