Fantastic service

“Fast, professional and efficient service. John arrived promptly and explained the various options available for replacing the lock on my front _door_ and then once agreed he did the work expertly ensuring that the new lock was lined up and matched the existing hardware. I can’t recommend him enough.”

John was great

“John was great, he came under 25 mins and changed my _lock_ as my latch required a key to turn the knob. Gave me pieces of advice which was useful. He’s definitely reliable and you can count on him to unlock your any of your woes.”

A good experience

Very straightforward

“Quick and efficient service. Emergency Locksmith arrived within 40min after being locked out. He explained the options and got the _door_ open by drilling and changed the lock. £490 for call out and new lock installed. Not cheap but got the job done quickly and professionally. Would use again and recommend to friends and family.”

I contacted this company as my _lock_ was

“I contacted this company as my _lock_ was spinning and no longer working. John attended to fit a new _lock_ I purchased. When removing the hardware, he went above and beyond identifying damage to the _lock_ and fixing it for me. He successfully replaced the _lock_ and also advised that a new mechanism may be required as it was slightly catching Did a very good job and would use again.”

Hero’s Open Doors

“Was _locked_ out this evening with my 4 year old, so I went to Google and searched emergency locksmith. I phoned the first number on Google London Locksmith 24h. They promised to send someone within 25-30 minutes. True to their word John Raul arrived in half hour, he was polite, professional and empathetic. John drilled the ancient door lock out and replaced with a shiny new working lock and gave us 2 keys. Would highly recommend this firm and John for your future locksmith emergencies.”

I had an issue with the lock which they

“I had an issue with the lock which they had fitted. They sent someone, John, immediately, 30 minutes after I reported the issue. John was very apologetic, saw the problem immediately and he fitted a completely new lock. This shows them to be a trustworthy company, that when things go wrong, which sometimes they do, they reacted immediately and set it right.”

I really received a perfect service

“I really received a perfect service. The person who came to my home arrived earlier than expected and the service was great and _quick_. He also explained how use the lock and advised me to do some changes. In general he was very polite. I asked his name John Raul . Thank you for your service.”

Great service from John

“John is great! He got us back into our house very promptly after we _locked_ ourselves out. The new lock was a little gammy and John came back the following week to help us diagnose the problem and fix it. He did an excellent job figuring out what was putting tension on the lock and causing the issue, and he oiled the lock and sanded down the frame to help with the problem. He also gave us advice on what we could get builders to do to make the door and lock even smoother. Really great work and super customer service!”

Fast, reliable locksmith service

“_Key_ snapped in my lock and John Raul came to the rescue very quickly. John was very helpful, professional and friendly - he did a quality job, quickly replacing the lock and clearly explaining options for keys etc. Thanks, John!”

_Locked_ myself out of my flat in the

“_Locked_ myself out of my flat in the rain. Called this company, they said it would be 20 mins, got there in about 10, took a total of 40 mins from being _locked_ out to in my flat with a new lock fitted. Very quick turnaround”

Great Service from John Raul!

“Had a great experience with John Raul. Had my bag stolen with all my details and keys and within 25 min was available to change our locks and make us feel safe! John was fast and provided us with a great service. The only downside is regarding the company which had quoted me £90-120 for the service and lock (too good to be true having had to change locks before) and price was much different at the end (and more aligned with our expectation)”

Gi gi what a guy

“Gi gi what a guy! He can over within a hour and got us into our house as we was _locked_ out, got my kids in and changed the lock and sorted out the door, very professional and polite and a very helpful guy! Will highly recommend him and the company for any lock issues! Thanks again Gi Gi.”

Back Inside Within an Hour, Thanks to Andrew

“Andrew contacted me within five minutes of making my booking and kept me updated on his arrival time. He reached me within 25 minutes and got straight to work. The lock was more difficult than expected but he handled it with complete professionalism and had me back inside within 10 minutes. He also replaced the barrel on the lock with no fuss. Outstanding service from start to finish. Andrew is an excellent locksmith and I highly recommend him.”

John Raul came to my rescue!

“John Raul came to my rescue after getting home late after work to find my lock not working. Came within 20 minutes as promised and promptly got my lock changed and fixed. Could not fault him. Very helpful and a lovely man! Thank you”

“_Key_ got damaged in the lock and the locksmith Gigi replaced the lock and adjusted the door making it secure. Gigi was very professional and took his time to explain what work he was carrying out and done a fantastic job”

Our back door locking mechanism

“Our back door locking mechanism completely failed late last _night_ so we had to make an emergency callout. Gigi arrived within half an hour and was extremely polite and professional. He made the door safe to lock and had to source an obsolete mechanism as the lock itself is very old. He was back the very next day with a replacement mechanism so we are back to a fully working 4 point locking mechanism. A truly professional service!”

Late on a Saturday _night_ I had my bag

“Late on a Saturday _night_ I had my bag stolen with my keys in it and no other way to get into our flat. We had a locksmith arrive by the time we got home meaning which was so quick. Sadly we had to have our locks drilled and replaced but Julian did everything quickly and efficiently. Within 45 mins we’re safe and sound.”

Very reliable

“Very reliable. I called them because my tenants broke the _key_ inside the lock, therefore they were locked outside, and I had Alin at my address in less than the mentioned 30 minutes of waiting time. Alin was nice, very polite, and always positive. He solved quickly, we had to replace the lock and the final work was really looking good. Huge thanks!”

Great service

“Gigi came and changed my lock late at _night_ in the freezing cold. He was polite, professional and efficient and went out of his way to help. Highly recommended.”

Lost keys, locked out - fixed in 60 minutes

“Andrew L arrived at my flat, within 20 minutes of me losing my key and reporting being locked out, at 11pm last _night_. He was extremely polite, professional, knowledgeable and skilful. Within 5 minutes I was back inside, and half an hour later he had replaced the lock he'd had to drill and the job was done - he had the required replacement cog-cylinder lock in the van. I cannot praise him and his company enough - from the first contact on the phone to final payment, I received helpful, supportive advice which allayed any fears that I may have had. The costs were outlined before work started, as was the level of disruption and noise (poor neighbours! Drilling metal at 11.15pm wasn't pleasant) - but it was swift and kept to a minimum. I absolutely recommend Lock Services London Ltd, as they completed everything as promised, and much more rapidly than I expected. Thank you, again, Andrew L.”

Thank you very much Gigi

“Gigi the locksmith was very useful and very helpful. He came in less then 25 minutes and save my _night_. I lost the key and I couldn’t get in my house. He open the door and replaced the lock in less then 20 min. Good price and he was very cordial and professional. Thank you”
