You could use a time delay relay with an interval function, such as:

If you can get the Arduino to respond to the remote door fob, it could easily turn on a relay for the time needed. You could use diode steering

logic to allow the seats to be warmed either from the Arduino (which would be directly off the battery), or the ignition. You could also add a temperature sensor to control the heat, and a battery voltage sensor that would keep the heating turned off if battery voltage dropped below a safe level.

Ideally: Push remote control button from inside house (15 feet from car), seats circuit turns o n for circa 5-10 minutes. If ignition is not started after 10 minutes, sea ts turn off. If ignitions is started, seats remain energized.

Paul, thank you so much for your reply. It has given me ideas and direction. Thanks again.
