Push-button start systems rely on a proximity smart key constantly communicating with sensors around the vehicle — when it works, you never think about it; when a key needs replacing or adding, it requires programming that goes beyond what a standard transponder key needs. These systems vary meaningfully between manufacturers in how proximity authentication and start authorization are handled.
We program proximity smart keys for push-to-start vehicles across most major brands, whether you need a single replacement after losing your only key or an additional smart key for another driver in the household.
