Both our car keys stopped working (tried changing the batteries multiple times with no luck) and Aaron came out to sort it quickly. Very friendly and much cheaper than Timpsons would have been.Bobby Moore17:15 14 Nov 25Couldn’t believe how fast he arrived — genuinely came out to me so quickly that I barely had time to panic. I called Locks on Sea Locksmiths expecting to be stuck for ages, but he was at my door within 20 minutes, calm, friendly, and ready to sort everything out.
From start to finish, the service was honestly faultless. He got my door open with absolutely no damage, which I was so relieved about. You can tell he knows exactly what he’s doing — proper professional, efficient, and clearly experienced.
The price was great, especially considering how fast and smooth the whole thing was. No messing around, no hidden charges, just solid, honest work. And on top of that, he was genuinely a good guy to deal with — polite, easy to talk to, and even smelt nice too 😂 Little things like that actually make the experience so much better when you’re stressed out.
Honestly, he was a saviour in a moment when I really needed someone reliable. If you ever end up locked out or in any kind of locksmith situation, I’d recommend Locks on Sea Locksmiths without hesitation. Top-tier service from a top-tier guy.D Ingram13:40 07 Nov 25Aaron was excellent! Really helpful before he came over and was able to come the same week.
