The spoiler going up an down,was because of the battery. The joke is, its a built in battery tester. The doors not Woking, is possible, a bad battery in the key fob. Mr miata, was asking about your case thinking, maybe it came apart, an your chip has fallen out ( if not he'll chime back in.) If you replace fob batteries , you have to resynthesize it to the car. Here a word of caution. Don't just keep resetting the battery over an over, there has be a horror story of ,30 tries at that an it fried the ECU.
