Acura Car Key Replacement: What Type of Key Does Your Model Use?
Acura has used several generations of key technology across its lineup, and the replacement process differs meaningfully depending on which type your vehicle uses. Older Acura models used basic transponder keys — a laser-cut or standard blade with a small chip embedded in the head that must be programmed to match your car's immobilizer system. Mid-generation models like certain RDX and TLX trims use proximity fobs with a physical blade backup, while newer Acura vehicles — particularly recent MDX and Integra models — rely entirely on a push-to-start smart key system. Each type requires different equipment to cut and program, and not all locksmiths carry the right hardware for Acura's more advanced systems. Our technicians do.
Understanding your exact trim, model year, and whether you have a working spare key on hand all affect both the process and the time required. For example, programming a replacement smart key for an Acura MDX involves communicating with the vehicle's BCM (body control module) in a way that a basic key duplication machine cannot do. We use professional-grade automotive programming tools to handle this on-site — the same job a dealer's service department would perform, but at your location in Los Angeles and typically faster. If you're not sure what type of key your Acura uses, just call 323-693-8007 and our team will walk you through it before we dispatch.
