Acura Key Types We Replace and Program
Acura has used four main key technologies over the years, and knowing which one your car requires determines how the replacement is made. Basic metal keys without a chip were used on early 1990s models and are the simplest to duplicate. Transponder keys — the most common type on Acuras from the late 1990s through the mid-2010s — have an embedded microchip in the plastic head that must be programmed to match your car's immobilizer, otherwise the engine won't start even if the cut is perfect. Remote head keys combine the transponder with lock/unlock buttons in one unit, common on models like the TL and MDX from roughly 2004 through 2013.
The newest Acura models use proximity smart keys, sometimes called push-to-start or key fobs, where the car senses the key in your pocket and starts at the push of a button. These require dealer-level programming equipment, and that's exactly what our mobile units carry. We also replace and resync standalone key fobs — the remotes used for keyless entry — when the buttons stop responding or a battery swap didn't fix the problem. If your fob was damaged by water or impact, we can assess whether reprogramming resolves it or whether a new unit needs to be cut and coded from scratch.
