It's lovely to meet someone who is truly passionate about what they do ❤️ Matt is an expert with Mercedes and keys. 100% recommend for honest, expert, friendly service, thanks 😊

Great job and really nice guys - Had an issue with an EIS on a Vito, Matt and team absolutely went out of their way to help and get this sorted. All done with super quick, with genuine MB parts, zero fuss and super easy to deal with. Highly recommend. Thanks guys

Called Matt when I had a problem with my EIS ignition on my W221 S Class Matt diagnosed what he thought the issue was on the phone and was bang on correct. I travelled up to the West Midlands to see him and he resolved the issue in less than an hour - something that I was being quoted 5 days+ via the post. Can't recommend Matt enough - he really knows his stuff - swift and friendly service. My new go to contact for anything Mercedes electrical related.

After a year of issues on my R129 and poor service from numerous Mercedes main dealers, I was pointed in Matt’s direction. What a great guy. Extremely helpful and knowledgeable. Thought there was no end in sight due to the car being built in a very narrow production window where various generation parts were used. I had previously been advised by another ‘specialist’ to remove the security system altogether (£1500+). Both keys rebuilt, very happy customer. Thank you Matt and the team!

After speaking with Matt it seems they (R.M.K.) cover more than the Greater Birmingham Area . I being in Wolverhampton was not a problem as R.M.K. supported garage services in and around my local area . Top chap got me sorted. Pro Key Diagnostics. swift , informative and great value. surprisingly they also cover other makers .worth the call
