1998 Honda Accord Ignition key

All 1998 had a recall on the ignition interlock
and ignition cylinder was replaced in most cases too
check key for excessive wear, if key is worn, cut new key
if you still cant turn the switch with the new key or the switch feels stiff, one or more of the tumblers may be worn. Remove and replace
if you parks on a hill set E brakes
step on brake try to rock and turn

to check on the recall have your VIN ready and call your locale dealer
good luck

Key interlock system prevents ignition key from being removed from ignition lock assembly unless shift lever is in Park. When ignition key is in ignition lock assembly, key interlock switch closes, providing voltage to key interlock solenoid and interlock control unit.
If shift lever is not in Park (parking pin switch on), interlock control unit energizes key interlock solenoid by completing ground circuit. When key interlock solenoid is energized, ignition key cannot be removed from ignition lock assembly. Key interlock switch and key interlock solenoid are located on ignition lock assembly.
Parking pin switch is located on bottom of shift lever. Interlock control unit is located behind left side of dash, near steering column.
