I don't think it is ignition tumbler failure that would make the ignition key difficult to turn in the ignition switch or possibly make the key difficult to withdraw from the ignition. Check your battery connections are clean tight and secure. Check your battery voltage at rest the battery voltage of a fully charged battery must be 12.6 volts, on starting the voltage across the battery shouldn't drop below 9 volts or you have high resistance in the starter circuit or bad electrical connections which need to be checked doing what is called a voltage drop test. Most likely your battery is weak, charge your battery see if the engine cranks faster.
