Toddler naps at 3 years old

My son will nap while in daycare from 12pm to 2pm- which he attends part time. But at home we have a really hard time getting him to nap. He comes out of his room. Won’t stay in his bed and it’s a struggle. So sometimes he falls asleep so late that it makes bedtime later. But if he doesn’t nap - he’s exhausted and dinner time is so hard. Does anyone have any tricks or suggestions for keeping toddlers in bed during nap time?
