The Best Locksmiths in Hemel Hempstead, Hertfordshire, United Kingdom (2025)

Super efficient really honest and friendly. We managed to break our car key and lost the blade. We put a call in at 21:00 and Stuart called just before he turned up. The wait time was about 45-50 minutes and he managed to sort a replacement key out in about 25 minutes. Excellent work

Stuart was really helpful and professional. He came out to my house and sorted my car battery and key coding issue at very short notice………and didn’t rip me off. I would definitely recommend him.

Fantastic experience with S J C Automotive - Mobile Auto locksmith I needed help with my car and they were incredibly professional and knowledgeable. Guided me through the steps over the phone and made what could have been a stressful situation so much easier. I’m so grateful for their support and would highly recommend them to anyone needing a trustworthy auto locksmith!

Gave some great advice when called with an immobiliser problem. Was patient and polite over the phone which was really appreciated when in a tight spot. Would definitely use again when needed.

Came out Sunday within half an hour of me calling. Adjusted striker plates. As front door wouldn't lock. Very pleasant chap. Would recommend and use him again if required.

Chris and his colleague were an absolute delight - I got through to them straight away and they arrived in exactly 20mins as promised. They got me into my house in about 5 seconds, and even proactively tightened up the loose lock on my front door - all for an incredibly reasonable price that I thought would be way more expensive. I wouldn't hesitate to call them again - they somehow made locking myself out a pleasant experience!

Super grateful for Chris and George's help today. They turned up the same afternoon we called and fixed 2 doors and 2 windows promptly with very reasonable price. Will not hesitate to recommend them to anyone.

Front door wouldn’t lock from the outside, called Chris and he was so nice on the phone. No call out fee, great communication and showed up within the timeframe provided. They diagnosed my problem straight away and sorted it within a few minutes. Really reasonable price as well! Very satisfied customer and felt so comfortable with both Chris and his son. Thanks guys! Will definitely recommend if anyone else needs a locksmith

Highly dependable. I’ve used his services more than once now and every time he’s been reliable, polite, and efficient.

The technician did an excellent job replacing our front door's entire locking system. Their promptness, courtesy, and professionalism were commendable. I wouldn't hesitate to recommend MacArthur Locksmith to friends and neighbors. Thanks for a job well done!

Brilliant, these guys came to us to help us with our cabinet where we display phones. We snapped the key in half and they got us a new key within a week. Saved us from replacing 6 locks. Thanks again

Above and beyond service. He didn’t just fix the lock—he also checked the door alignment and made a few adjustments to stop it sticking. Really appreciated.

Always helpful . For a general diy product they recommended an alternative supplier at a lower price. I will always go there for such advice.

The go to place for any car needs or advice. Staff always friendly, helpful and knowledgeable. 100% recommended.

Great Service! Copied my key and got it right the first time! 🙏🏾

Brilliant place my windscreen wiper pinged off so rang them to see if new ones in stock. Went to the shop where a lovely guy actually managed to clip it back on for me saving me the cost of new ones which I don't need right at this moment. Highly recommend this lovely business

Did a good job

I had to get a new proximity key fob for my car, called them up, spoke Steve, and he quoted me over a £100 less than anywhere else. The service was superb, he asked what level I had parked on, and he told me it would be about an hour, so I went for coffee. Sure enough, I got a call an hour later. Picked up the fob, he said he'd been to my car and made sure everything worked as it should, and it does. I'd definitely use them again.

I cannot tell you how highly I rate this shop (I should really know your name by now) I trust my, to me very very precious boots with you over and over, this one occasion I stupidly took them to another branch (purely for convenience) and oh my god they were ruined (this shall be in a review on their branch) but you within the Marlows shopping centre I shall never cheat again, your work is magic and second to none, not only did you bring them back to life, you saved them. I could have cried at how bad they were but you restored them to their former glory. A true skilled worker who clearly enjoys your job. Thank you for your hard work. See you soon. I highly recommend your craftsmanship.

Visited Timpsons at Jarman Park to get my Key Re-Shelled . Great customer Service, Tristan went out above and beyond - would Definitely recommend and will definitely be back
