take out key while car running, how to do this? Options

[black13]

so its cold up here and i want to warm the car but not stay inside it as its cold.

Got 94 auto with viper alarm but no remote start.

Is there a way to just take out the key while car is running (i tried this in Park and Neutral positions and key wouldn't come out)
I also tried locking the doors but that doesn't work either when car is running.

So whats easier, a way to take out the key if there is a way or to just get remote start installed?

id start the celica, set the turbo timer for the max time, 10 mins on the apexi.
and do what i needed to do. if someone puts the e-brake down the car shuts off. so a cheap ebay turbo timer could do what you want it to do. since you take the key out im sure you could lock the doors too. i think.
