Services
UPVC Lock Repair We repair jammed and faulty uPVC locks without requiring a full door replacement, even on older mechanisms through sourcing and upgrading components. Early stiffness is a key sign of misalignment, which we correct before major failure occurs. If a lock does fail, we open the door without damage and restore full operation. Secure upgrades and re-alignment are always included.
Lock Upgrades
Report
Lock Upgrades Security standards evolve as new break-in techniques emerge, and older locks may no longer provide adequate protection. We assess existing hardware to identify vulnerabilities and recommend suitable improvements. Many properties fail to meet current insurance requirements without proper updates. We supply and install compliant products to maintain valid coverage and offer free, no-obligation assessments.
Anti Snap Locks
Report
Anti Snap Locks We specialize in fitting advanced anti-snap locks designed to prevent euro cylinder break-ins. This method of attack has become widespread and targets standard door locks with speed. Our approved 3-star SS312 cylinders meet all current industry testing standards. They deliver robust protection against every common attack method. This solution offers maximum resistance while remaining competitively priced.
SY Locksmiths Each lockout is treated as a critical priority with rapid dispatch as our standard. Over 30 years in the trade enables us to open locks without unnecessary damage. We use professional-grade, modern tools designed for controlled, precise entry. When keys are missing, broken, or the mechanism fails, we restore access with efficiency and care.

Excellent service. Our back door lock broke. He had same day availablility, and came and replaced it for a flat rate fee. Really easy to communicate with via text, resonable price as well. Will be using him again if we have any other issues!

Brilliant service. I needed a new lock and handle for a back door and stable door window and Steve was so helpful and gave great advice. He popped round the same day, Steve ordered multiple handles to make sure I got the finish that I wanted. Made the process very easy. I didnt realise he will also cut extra keys for your new locks at half the price Timpsons do so order from him if you want extra spares!

I had an issue with my external door, rang Steve for some advice he was so helpful and professional gave me all the information I needed. I was stressing because the door wasnt secure he came the same day to secure the door and changed the locks for me so I could use it and the came back the next day once the steel plates had been delivered to fit them to fix the door. I could not have asked for anyone better to come along that day and sort my door out! 100% would recommend Stes services I am and will be forever grateful!

Steve was highly efficient and knowledgeable but also really warm and friendly. He gave really impartial advice- advising us to upgrade one set of locks but not another which didnt need it.

Highly recommended!

Steve has been great. We had most of our locks replaced and he talked us through what was best for the type of security we wanted. Completed the work quickly and everything works exactly as it should. Highly recommend
