Contacted Steve on a Friday night about a jammed lock and he replaced it by Saturday morning. Great service and really good value for money! Very friendly and fast service.

Steve was great, and I highly recommend him as a locksmith! He responded to my query quickly, he showed up to fix my lock when he said he would, he charges a fair price, and he was friendly throughout. What more can you ask for? You can't go wrong with Steve at SY Locksmiths

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.

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 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.

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.

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
