Used Lock Assist a few times and always received first-class service. Phoned in the morning and Karl arrived few hours later to fix lock on our French doors. He also fixed some loose window catches Friendly, reliable, and great service; would highly recommend.

Having locked my external porch door and left the key in the lock, I shut the internal front door, which has a Yale lock. When I next needed to go out I was unable to open the internal door as it had swollen and was stuck closed. I tried to use adjustable pliers to pull on the Yale handle and snapped it off! As a result I couldn’t open either door. I contacted Lock Assist, based on their Which? local reviews, and Karl came the next day to fix it. He removed and replaced the Yale lock and sorted the sticking door. I can’t speak highly enough of his work. He was pleasant and polite and carefully cleared any debris before he left. The price was reasonable and I would definitely recommend the company and use them again.

Replaced a failing back door lock. Excellent same day service at a reasonable cost. The installer wasn't happy with the functioning of the new lock out-of-box and went back to the office to get a better one. Also provided additional spare keys. Everything left clean and tidy.

If something is not right - even new and out of the box, we wouldn't dream of fitting it and passing the buck to you! Thank you for writing and posting your review - much appreciated. Regards, Paul.

I contacted Lock Assist after initially calling out a firm found online. When the operative arrived and wanted to drill out the lock before he really looked at it or asked any questions, I became suspicious - even more so because he said until the lock was drilled out he could not indicate a price! I sent him away and then looked up how to find a trustworthy locksmith - only to discover the MLA site - hence leading me to Lock Assist. Karl could not have been more helpful - he replaced the old ERA lock and plate and even moved the striking plate for the Yale lock on the front door as it was not aligned correctly. The price was extremely reasonable and the main takeaway for me was feeling I could trust Karl. I had a lucky escape, particularly as when I looked online later the very firm I had contacted originally had been cited by many others as scammers!

We're glad you realised early on that the person you called didn't know what they were doing and sent them away - even if you did have to pay their call out - but it probably saved you £100's in the long run! Thank you for writing and posting your review - much appreciated. Regards, Paul.

Paul attended our property about 20 minutes after I contacted him. Within a very short time he fixed the broken lock in our front door, adjusted the four door so that it actually shuts smoothly now and fixed an additional issue with the back door. He did all of this efficiently and willingly. Paul is a friendly and amiable gentleman, provided a great service at a reasonable price and I wouldn’t hesitate to use him again. Thank you Lock Assist!

Left key in door on the inside, called to understand options. Explained clearly the price and options for getting entry and also replacing the lock to an easy spin option so no key can be left inside in the future. Very clear with prices, no hidden calls out or extras as per some other companies have had to use in the past. Nice and friendly also, clean and quickly done.

Called the office at 4.25pm as our UPVC front door multi-lock had seized and we were unable to lock the door. Karl came out immediately, and by 5.15pm had fixed the lock by replacing the lock gearbox and the key barrel, which had also become worn. Explained everything as it was being repaired. Both Karl and Paul who I subsequently spoke to were very friendly, very experienced and professional. Very happy with the price charged, and would definitely recommend Lock Assist, and will certainly use them again if we ever need a locksmith.
