Acura Car Key Replacement: What Type of Key Does Your Vehicle Use?
Not all Acura keys are the same, and identifying what you have is the first step toward getting back on the road. Older Acura models from the late 1990s and early 2000s used basic laser-cut or high-security mechanical keys — more complex than a standard house key, but programmable without a dealer-level scan tool in most cases. From the mid-2000s onward, Acura shifted heavily toward transponder keys, which contain a small chip in the key head that communicates with the vehicle's immobilizer system. If that chip is absent, damaged, or unprogrammed, the engine will crank but will not start. Popular models like the Acura MDX, RDX, TLX, and the returning Integra all fall into this category.
More recent Acura vehicles use proximity smart keys — often called key fobs or key cards — that allow push-button start without inserting anything into the ignition. These require specialized programming equipment that reads and writes directly to the vehicle's ECU. Our mobile technicians carry professional-grade key programmers capable of working across the full Acura lineup. We cut new keys on-site using precision key-cutting machinery, and we complete transponder or smart-key programming right there at your location. The final quote you receive before we start reflects factors like the specific model year, the type of key or fob required, any parts that need to be sourced, and the time and location of the call — there are no surprise charges after the fact.
