- KPKendra PrestonMar 21, 20265.0The Key family and their team are always amazing! Everything is so efficient and transparent! Took my car in for an oil change, complained about my dim headlights and they offered to replace them 😍 then I received a walk around video showing some concerns. When I asked for the cost I received a detailed estimate (💚 transparency). They were able to do all the work in just a couple of hours while I hung out in the charming town of Williamston. Thank you for taking such great, honest care of me!
- LKLisa KeithMar 20, 20265.0I brought my vehicle in for a routine oil change, and I walked away genuinely impressed. The service was quick, professional, and fairly priced — but what really stood out was the team's thoroughness. While the technicians had my car up on the lift, they took the time to do a complimentary inspection and flagged a few preventative maintenance items I wasn't even aware of. They walked me through exactly what they found, explained why each item would eventually need attention, and gave me clear, honest estimates on the spot — no pressure, no upselling, just straight talk. Key Diesel has earned a loyal customer. If you're looking for a trustworthy, knowledgeable auto shop that goes above and beyond, look no further!
