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!

Paul came out to help me gain access to my home when I went out and lost my keys. He was polite, friendly and helpful. He gave me a fair price and arrived within an hour. I would definitely use him again and I highly recommend him

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.

Great service from start to finish. Sarah was great on the phone. The Paul and Karl arrived quickly, were professional, super friendly and clearly knew what they were doing. They explained everything before starting and had the job done efficiently with no hassle. Pricing was fair and transparent too, which I really appreciated. Would definitely recommend and use again if needed.

Front door lock failed on Sunday, contacted Lock Assist Monday morning and they responded immediately, and resolved the problem. They had previously repaired the lock 8 months earlier, but without any input from us submitted their invoice in the amount of £0.00 advising that the earlier repair had used an incorrect part and no payment was required. Exceptional service which was very much appreciated.

Thank you for writing and posting your wonderful review, which we are very proud of. If something isn’t quite right, it is unfair to make a charge to the customer. Kind regards, Paul.

Called after 9am with front door lock mechanism which had failed. Followed up with emailed photo of lock/door. Two technicians arrived about 2pm and replaced failed central gearbox mechanism, leaving me with a fully functioning front door within 6 hours. They could have done it even quicker if I had not had to take my wife out in the morning.
