My old doorbell is gone, wires are exposed at the door. Can I just reattach them to a new one, or tape them?

Do not tape exposed wires. Use a multimeter to check for voltage at the wires. Standard doorbells use low voltage, typically 16-24V AC, which you can usually connect yourself to a new doorbell. If there's no voltage, or higher voltage, locate your doorbell transformer. If the transformer is inside the main electrical panel, or if you're not comfortable working with wiring, call a licensed electrician.
