Types of Acura Keys We Replace
Acura has evolved its key technology considerably over the years, and the right replacement approach depends entirely on what your specific model year requires. Older Acura models used a basic laser-cut or high-security mechanical key without any embedded electronics — these can be cut to code on-site using your VIN and vehicle documentation. Models from the mid-1990s onward began incorporating transponder chips inside the key head; the chip must be programmed to match your vehicle's immobilizer or the engine will crank but refuse to start. If you've ever had a new key cut at a hardware store only to find the car won't turn over, this is exactly why.
Later Acura models use remote head keys that combine a mechanical blade with a built-in key fob, allowing you to lock, unlock, and pop the trunk remotely. The most recent generations — many MDX, RDX, and TLX trims — use proximity smart keys with push-button start. With a smart key, the car detects the fob in your pocket or bag, so there is no blade to insert; programming these requires direct access to the vehicle's OBD port and dealer-level software. Our mobile units are equipped for all of these scenarios, from basic transponder programming to full smart key generation.
