Services
UPVC Lock Repair We repair and upgrade uPVC door locking systems with a focus on long-lasting results and dependable security. Obsolete locks can often be replaced with improved modern mechanisms without changing the entire door. If your handle or lock feels stiff, we can adjust the alignment before the mechanism fails completely. Our repairs are completed carefully to restore smooth locking and reliable performance.
Lock Upgrades

Lock Upgrades Our professional lock upgrade service helps ensure your property benefits from modern security standards. Locks that were fitted years ago may now be vulnerable to advanced methods of entry and could fall short of insurance requirements. We supply and install compliant BS3621 and SS312 locking systems to improve security and maintain cover eligibility. We can also assess your existing locks and advise on any necessary upgrades.
Anti Snap Locks
Report

To further strengthen door security, we can also install high-security handles and sash jammers. Every product we supply is chosen for its proven performance and quality.

With more than 30 years of locksmith experience, we are highly experienced in non-destructive lock opening methods. We arrive fully equipped with professional lock opening equipment designed for a range of lock issues. If a key has broken, disappeared, or the lock has malfunctioned, we select the most appropriate method to restore access efficiently.

Steve was prompt at getting in touch. Completed all the work to a sticky front door, within a couple of days. His price was very reasonable. I would definitely recommend him.

This is the right guy. Steve turned up in 20 mins, fixed both our issues (+ sorted a few other issues we had re door handles and locks) all within the hour. Very competent, efficient and fairly priced. Dont lock yourself out of your house. But if you do, phone Steve!

Fantastic service. Steve was brilliant : top bloke, personable, fantastic service. We just moved into our new house, the lock broke on the second day. Steve answered straight away and was flexible to work around two young kids. Offered lots of relevant information and provided two brand new locks. Door operates a hell of a lot better now. Would 100% recommend.

Steve came round the other day to open up our *chamber of secrets* (a little workshop which we didn't had the key to when we bought this house). He's a very friendly lad, had a good chat too. I hope we don't run into any issues needing a locksmith any time soon, but if we do, I won't call anyone but him.

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!

All great - fitted me in at pretty short notice, turned up on time and did the work quickly and to my untrained eye to a high quality! Can't really ask for more!

Steve is friendly, professional and changed my vintage and broken lock for a similar one. He gave me advice on my doors and made me feel very reassured. I would highly recommend. Great guy

Steve at SY Locksmiths did a great job of mending and adjusting a tilt & slide door for me where the latch driver mechanism had sheared inside due to wear. Two other locksmiths had declined to help. I should have gone straight to SY Locksmiths and will certainly do so next time!
Really helpful, reliable, great communication and certainly a skilled expert. Recommended.

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!

Steven was at my house in under an hour after I first messaged him to say my front door lock had jammed. He was clear up front on his pricing, and talked me through what options were available to me, and was also able to change the locks on another door while he was there. He also gave me some good followup security advice which was very appreciated.

Steve turned up within 15mins to sort out my mother in laws front door lock. She is an elderly lady who couldnt get into her house and was quite upset, so to have such a great service was invaluable. Would definitely recommend to others.

Fantastic service! Called Steve at 4pm on a Saturday as we couldn't lock our back door. He came out within the hour and sorted the problem quickly. He also had a look at our front door and made a few adjustments to that too. Overall, a brilliant service. Highly recommended

Steve provided an excellent service. He is polite, knowledgeable and informative. He fixed the locking mechanism on a UPVC door and upgraded the locks to 3* for security. He was also happy to share what we should do to keep our new hardware working smoothly for years to come: highly recommend.
