A prompt, polite and professional response to a non urgent request on Saturday, resulting in a replacement lock on Monday morning. Pricing was transparent. Thank you Larry.

Used LS Ltd for the first time to sort the front door of my elderly mothers flat, when a key had snapped in the lock preventing access. Larry turned up very swiftly, outside working hours, and sorted the problem quickly and efficiently. Will certainly use them again. Highly recommended.

Night-latch on front door failed so not able to open. Made contact via e-mail over the weekend and was happy to wait until the Monday as not an emergency. Had a call from Dean on the Monday morning who visited that afternoon, took the old latch off and replaced it with a new one. Very efficient, courteous and professional.

Called Larry for issue with front door latch and he came to our rescue the same day and Dean followed up for part 2 later that day. Great team and impressive knowledge and advice. Something which could have been a headache for us was resolved quickly and expertly by them. Great communication and follow through of actions. Thank you both so much.

Dean was excellent. He arrived quickly to fix a lock on bi-fold doors. Offered advice on the parts needed and completed the job promptly and efficiently and when he said he would. I can’t recommend Locksmith Services Ltd highly enough.

We called out Larry Locksmith a week ago to fix a jammed internal lock between the house and our garage. Rapid response and speedily sorted. During the past ten years, we have needed Larry’s services three times, and on every occasion, Larry or Dean has been able to sort out the issue immediately or advise a solution. A couple of days ago, I recommended Larry to a close friend to fix a front door lock problem. I’ve just heard that my friend was delighted with the service from Larry Locksmith.

What a joy to deal with Dean at Locksmith Services Limited - easy to communicate with, great workmanship, very knowledgeable. He came 40 plus miles from their base to get here - my mother has also used them and there again they did a brilliant job.

The end bits of a key broke off in my front door deadbolt lock and could not be accessed, so I called Locksmiths Services and Dean was here in under an hour; retrieved the broken section and moved the doorjamb part of the lock so the lock caught better and works a lot easier.

Outstanding service again - the third time Larry and Dean have helped us out in the last year. Dean was knowledgeable, clear in his advice and recommendations, reliable and efficient. He replaced locks, window handles and window mechanisms quickly and without any fuss and at a reasonable price. A great father and son team - thoroughly recommended.
