Some words from our customers

  • Darren C

    I required a secondary key for a Mercedes Benz import I had just purchased, after researching for this service via trademe and MercKeys I came across Dale. Top man, expert knowledge and truly fantastic service. He was simply a breeze to deal with and was very quick and on point. He took all the stress out of the situation for me. Dale, thank you very much Sir!

    Dale from Merckeys is an absolute legend!! A MASTER technician and a stand up bloke!! Dale from Merckeys went above and beyond to accommodate for my situation. Dale worked fast and explained what he was doing step by step for my simple mind. I saved ALOT of money as I was going to get charged an arm and a leg then some from an aftermarket workshop. I give Dale 10 out of 10 rating and will most definitely be recommending Merckeys. Thanks Dale and Merckeys simply the best!!? From a Mercedes owner on a low budget much appreciated.

    Being a Merc owner with a W202 97 C class c230, my old key was beginning to die a slow death until it packed up 2 days ago, at a shopping center. Not able to get back into the car, i asked the Merc dealership down the road to assist, and they told me a new key would cost 3900 and 3 weeks to arrive. With no such time on my hands, I found Merc keys and had such great customer service and assistance from them. 2 hours later my car was up and running with a new key. Thanks again.
