I have keys, but no locks and space, and no rooms. You can enter, but you can’t go outside. What am I?

A keyboard.

Did You Know?

This riddle plays on double meanings — a keyboard has keys you press (not locks), a space bar (not a room), and an Enter key (but you can't exit through it)! The QWERTY keyboard layout we use today was designed in the 1870s to prevent mechanical typewriter jams by separating commonly paired letters. The average person types around 40 words per minute, while professional typists can reach 75-80 WPM.
