Car keys are fast becoming a thing of the past. But can you add a push-button start to an older car?

Thanks to ididit and their id.PUSH+ Push Button Start Kit classic car owners can add the luxury of keyless entry and remote start in their classic rides.

The id.PUSH keyless ignition system is as easy as it gets: just push the button and go! This basic push-button system features a mechanical push-button start with LED halo lighting.

Ward's Auto, an industry-watcher that recently started tracking installation rates of push-button ignitions, reports 25.4 percent, or 4.4 million, 2013 model-year cars and trucks sold had the feature.
