If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.

Car wouldn't crank, had to replace starter. Only took me an hour or so to pull the old and put in a new one.
Had to replace starter. But it is so easy on this model. You don't have to crawl under car. Just remove the air box for easy access.
Turn ignition on and it clicks,keep trying it multiple times and finally fires up.think it may be starter and just change it over and see if that fixes the problem
new starter, new alternator, and a new battery
