You're in good hands

We’ve been using Core Diagnostics since 2022 for our auto locksmiths business, helping with lock-sets, key and module programming on vehicles where it’s very difficult to get accredited with the manufacturer dealer tool. For example Renault, Nissan, Maxus, BMW and Stellantis.

You’re in good hands with everyone at core, but I’d like to give a mention to Brandon who I’ve found always goes above and beyond for us to get the job done.

Always super helpful

I use these guys on a weekly basis and they are always super helpful. They have done countless of mechatronic gearbox calibrations for our garage and software updates. It’s great to use these guys so that you don’t have to make the trip to main dealer and I can do it all in house. I can’t thank them enough.

Saved a lot of headaches over the years

Have been a customer of Core Diagnostics for quite a few years now,. Their technicians are top tier and saved a lot of headaches over the years.

If there's an issue they put their all in to trying to solve it. Couldn't recommend a better remote diagnostics company and made a great relationship with them.

The team at Core go over and above

I have been using Core for a few months now covering a range of things through ADAS, component coding and other remote diagnostic needs.

The team at Core go over and above on all occasions and in my opinion after using multiple remote diagnostic services over a 10 year period offer a far superior service in all areas.

Core diagnostics has been one of the best investments I’ve made for my business. Due to their amount of manufacture tools I have been able to except more work along with getting the more troublesome jobs out the door also.

Across the team their knowledge is second to none and they are all a pleasure to work with and deal with throughout the team, the team on the remote service are always very helpful along with Martyn and Steve.

The knowledge and experience is on another level

First met Martyn when we first had our demo of the ADAS Calibration machines. What a wonderful gentleman, the knowledge and experience is on another level.


If it was not for Martyn I don't think we would've brought the machine or gone with core diagnostics. We are very new in the industry but watch this space with this company and support we going to be massive.

As the journey continues I hope we grow and our working relationship gets better and better and we grow together as a team.

If your looking for a good honest company get in touch (ask for Martyn).

2024 Renault Kangoo electric handbrake service

Whist servicing our local parts suppliers delivery van it was found it required rear brake pads.

At 4.45pm we found our equipment could not carry out this procedure. I contacted Core Diagnostics and got the folks on channel and job completed before finishing time. More importantly the van was back on the road for the following morning.

This online easy connection can help us with jobs like this and also product and key programming with no licence or pass through fees, it's a godsend and run by experts.

Thanks Core as always.
