Key Certified Pre-Owned Vehicles in Portsmouth, NH

Key Certified Pre-Owned Vehicles
Buying a Key Certified Pre-Owned vehicle can make your used car purchase and ownership worry-free. Because every Key Certified Vehicle is one you can trust.





Each Key Certified Pre-Owned Vehicle Comes With:



Comprehensive 70-Point Vehicle Inspection
(Includes tires, brakes, engine, transmission, all power options and electrical items)

Before a vehicle can be marked as a Key Certified Pre-Owned Vehicle, it must undergo a rigorous 70-point inspection to ensure that the functionality, safety, and condition meets Key requirements. After going through our inspection, all Key Certified Pre-Owned Vehicles also go through state inspection to ensure reliability of the vehicle.
 You can be confident that your Key Certified Pre-Owned Vehicle will be on the road for years to come.


Key Certified Vehicle Warranty

No two pre-owned vehicles are alike, so why should the warranty be? Each Key Certified Pre-Owned Vehicle has its own unique warranty based on year and mileage to make sure you get the most out of the vehicle you are purchasing. Key Auto also has a wide variety of facilities to assist you in the event your vehicle does need service or repairs in the future.



Vehicle Reconditioning

Before being put on the lot for sale, each Key Certified Pre-Owned Vehicle is given a state-of-the-art detailing inside and out that makes it look, feel and smell brand new.





Tax Title and Tags not included in vehicles prices shown and must be paid by the purchaser. While great effort is made to ensure the accuracy of the information on this site, errors do occur, so please verify information with a sales consultant. This is easily done by calling us or by visiting us at the dealership.
