Acura Car Key Replacement: What Type of Key Does Your Model Use?
Not every Acura key is the same, and identifying your key type before we arrive helps us bring the right equipment on the first visit. Older Acura models — some early TL and CL generations — used a basic laser-cut 'high-security' metal key with no electronic chip. Anything produced in roughly the last fifteen years will have at minimum a transponder chip embedded in the key head. The chip must be programmed to match your vehicle's immobilizer, or the engine simply will not start even if the physical cut is perfect. Models like the MDX, RDX, and TLX moved on to remote-head keys and then to proximity smart keys that unlock doors and start the engine as long as the fob stays in your pocket or bag.
The latest Acura Integra and refreshed MDX trims use a compact smart key with push-button start — these require programming via an OBD-II interface and, in some cases, synchronization with the vehicle's security module. Our technicians carry the diagnostic and programming tools to handle all of these formats. When you call us after finding yourself with an Acura MDX with locked keys in the car, or after snapping a key in the ignition of an older Integra, we'll ask a few quick questions to confirm the exact equipment we need before we head your way.
