Called Aaron at 20.00 on a Saturday as my Discovery decided to lock it’s self with keys inside, ( my own fault but it never happened before in 3 years working there) , booked him Sunday as the entry restrictions of the location of car was in secure port. He suggested 08.00 which was perfect for me too!
He arrived, and was really professional, obviously likes locksmithing. Great to deal with, and I was so happy to get back into my car so I could travel back to Dorset.
Thank you very much for coming out on a Sunday morning,

Couldn’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.

I was very impressed with the service I received from locks on sea. Aaron came to look at my windows that had been stuck fast for several years - he measured up and quoted for me the same day. As soon as the parts that he needed were in he came and fixed my windows, it’s so nice to be able to open them again especially now the weather is so hot. Thanks locks on sea 👍🏻

Essex Lock Upgrades fAQ's
If you need some quick assistance, here are a few common industry queries we get asked a lot.
When should I consider changing my Essex home locks?
We generally recommend an upgrade if your locks are more than 10 years old, showing signs of wear (such as sticking or difficulty turning), or if you have recently moved into a new home. A quick upgrade to modernised home security lock standards can help prevent the most common burglary methods used today.
Do you charge a callout fee for Essex lock assessments?
No, we do not charge a call-out fee to assess your Essex property. Whether you need an emergency repair or a planned upgrade, you only pay for the work we do and the parts we provide. We provide clear, upfront pricing so there are never any hidden surprises on your bill, for full transparency.
Can you upgrade locks for Essex businesses as well as homes?
Absolutely. We specialise across homes and businesses, and we are fully qualified to handle commercial lock upgrades across Essex. We can install heavy-duty mortice locks, master-key systems, and high-traffic security solutions for offices, shops, and industrial units. If your business security feels outdated, we can provide a robust solution to protect you and your peace of mind.
Which brand of Lock supplies do you work with?
We only work with trusted, industry-accredited suppliers to ensure your security lasts. Our preferred brands include Yale, Chubb/Union, ERA, and ABS (Avocet). These manufacturers are known for their reliability and high-security certifications, ensuring your new locks perform perfectly 24/7.
