Super service, reasonable fee
My daughter who was visiting accidentally locked her car keys in the boot of her Audi TT, I phoned Fedelis and a guy turned up in under 30 minutes, he unlocked the car and boot , we retrieved the key all in under an hour, great service from a nice competent man, at a reasonable cost.

Unlocked!
We called in Fidelis to unlock two loft doors at our flats. They got here quickly at a convenient time. The locks were not easy to get at, but they achieved both unlockings. I watched them at work. So I now know the technique! But we will still use Fidelis in future.

Fidelis Security- Great company!
This was the second time I have used Fidelis Security to fix locks at my parent's home. Jay in the office sourced correctly the required heritage shoot bolt from a photo I sent ( at nearly half the price the door installer wanted to charge) and Paul replaced the broken one with the new one in less than 10 minutes. I was able to be invoiced and oaid by BACS... a pleasure doing business with this friendly, helpful and knowledgeable company. 5 Star!
First Class Service
The multipoint gearbox on my double-glazed door broke, rendering it inoperable. I called Fidelity Security & Locksmiths, as a Which Recommended Trader, and they were able to come the same day. The new gearbox was fitted swiftly and efficiently, and the fee charged was very reasonable. A couple of days later, I experienced a small problem with the door related to the repair and called FSL. Without the slightest hesitation, they agreed to come out that day and look at the door. They spent quite some time successfully fixing the problem without charging any more for their efforts. I could not have wished for better service.
Refreshingly Brilliant!
As they are a Which? Trusted Trader, i called Fidelis Security after being unable to open the front door to the house after shopping. So glad i did! Cameron arrived within an hour of calling and somehow managed to open the door without any damage or mess in no time. He diagnosed the cause and put it right without having to supply any further parts. I felt his priority was to offer a professional, pleasant experience for the customer at a very reasonable price which he did very, very well! He also put right a faulty patio door while here which wasn’t mentioned in the phone call. A brilliant experience for my partner and I and would not hesitate to use them again. Thank you so much!!
Endorsement Reference
Fidelis Security have provided alarm cover and keyholding cover for us for many years. Although we don't have many incidents, when they do arise they have always provided a very prompt service. Recently we had a specific security issue with our main entrance door, they attended on what was quite a cold day and spent several hours correcting the fault so that we again had a secure entry way. We have always found them to be highly professional.

Fidelis came promptly and sorted out the problem with my lock most efficiently. The service I received was excellent
Endorsement Reference
Amazingly quick response to being locked out on a Sunday. So helpful and informative and was back in my house in no time at all without any damage to my door or existing locks. Fantastic service at competitive rate.
Endorsement Reference
I needed a front door lock barrel replaced and a patio door lock replaced. They searched to find the perfect match for my old patio door and came back to me to fix it. They were quite frankly incredible, straight forward and not ridiculously expensive. They are currently just doing another job for me. Couldn't be happier with their service.
Endorsement Reference
Lost my spare key for my car was quoted a very competitive price. Work completed quickly and efficiently.
Endorsement Reference
I purchase a secondhand car in October 2023. It only came with one key. After ringing around this was the most helpful place and most reasonable. My husband and I took the car over the the workshop which was 25 miles away but still worth the trip re potential cost of the new key. The guys that dealt with us couldn't have been nicer and even reprogrammed a key that I'd found in the glovebox meaning the cost was even lower. We were there for about one hour. Wouldn't hesitate to use again or recommend.

Locksmithing isn't government-regulated in the UK, so anyone can trade as one. The Master Locksmiths Association vets, inspects and background-checks its members - a useful extra assurance for this trade.
Find an MLA-approved locksmithGet the call-out fee AND the total price agreed in writing before they set off. Emergency locksmith overcharging is a common complaint.
Be wary of anyone who insists on drilling the lock straight away: most locks can be picked open, and drilling then selling a replacement is a known upsell.
Look for a locksmith approved by the Master Locksmiths Association. The MLA vets and inspects its members, and locksmithing is otherwise unregulated.
