Typical sign of a flat battery. If you can charge the battery, or get a jump start from another vehicle, it may recover. If not, it may need a new battery, or the alternator checked out etc. Check that battery connections are clean & tight, & have not heated up after attempting to start, which would indicate corroded connections.
