What Causes a Motorcycle Key to Not Turn When Inserted?

[DeMiguel]

Motorcycle keys failing to turn when inserted are generally due to rust inside the lock or misalignment of the keyhole. Below are detailed explanations for the reasons why a key may not turn: 1. Rusty Lock Cylinder: First, remove the key and drip a few drops of engine oil into the keyhole, then insert the key and repeatedly move it back and forth. If the lock cylinder is severely aged, it may be necessary to replace the motorcycle lock. 2. Misaligned Keyhole: After several attempts, if the key still does not turn, the lock may be aged and require replacement of the lock cylinder. Check if the key is the original one and inspect it for any damage or deformation. Note: After inserting the key, gently wiggle the handle before attempting to turn the key; avoid using excessive force.
