A key that will not turn is usually a steering wheel lock, a worn key or tumbler, or a stuck steering column. Try the easy fixes first before paying a locksmith.
If you parked with wheels turned, the steering lock pin binds against the key. The fastest fix on this list - jiggle the wheel left and right while turning the key.
After 100,000+ turns, the key edges and the lock pins both round off. A new key cut to code from the dealer often solves it.
On keyless cars, low fob battery prevents the start button from working. Hold the fob directly against the start button - most cars have a backup reader there.
Debris, a broken tumbler spring, or seized internals stop rotation entirely. Replacement requires partial column disassembly.
Many cars lock the key in until the shifter is fully in PARK. Even 1/4 inch off can prevent removal or rotation.
The key snaps off in the lock, the cylinder spins freely without engaging, or you smell burning electrical from the column. Forcing it further can require a full ignition assembly replacement at $600+.

A new key is $25-$200. A locksmith service call is $80-$150. Replacing the ignition cylinder is $250-$650 total at a shop.
Wheels turned at park puts pressure on the steering lock pin. Rocking the wheel releases that pressure and lets the key rotate.
Yes if it turns now, but expect repeat issues. Worn tumblers get worse over a few weeks. Plan to replace the cylinder soon.
Usually a dead fob battery. Hold the fob directly against the start button and try again. Most cars have a backup transponder reader there.
