We had such a great experience with Optimus Locksmith! We first spoke on Wednesday about changing our locks, and by Friday everything was already done! Quick, smooth, and completely stress free. He was super friendly, professional, and really efficient. We’re very happy with the service and would highly recommend!

Outstanding service! Fixed my door promptly, supplied a new lock, and clearly demonstrated how to use it. Later in the week, I had a few queries, and they were more than happy to assist—even visiting to ensure everything was perfect. No problem was too small, and the professionalism and attention to detail gave me great peace of mind. Highly recommended to anyone needing reliable support

Big thanks to Gavin for getting out to me so quickly when my door wouldn’t lock! He arrived fast, was friendly and professional, and had the problem sorted in no time. Really appreciated how he explained what went wrong and made sure everything was working perfectly before leaving

Called Optimus late on a Friday evening to gain access to a property in Corby that a tenant had lost the keys to. Gavin was on-site within 15 minute's and my tenant was back in the property within 25 minutes. All for a reasonable price!

Called Optimus out this evening as our front door lock had failed and we were unable to secure the door.

From taking the call to upgrading our locks the process was fast and simple.

Highly recommended!
