Step 4 - Dirt and debris inside the key lock can cause the tumbler assembly to stick and jam, not allowing one or more of the key followers to operate.

Step 6 - Due to the nature of a lock, internal components can wear causing the lock to stop operating. In this case the ignition lock must be replaced.

Step 7 - In extreme conditions such as high mileage or a key chain adorned with many ornaments can wear the tumbler which causes the key not to work.

If the door key is same as the ignition key, the door tumbler can be removed and a key made if no security chip is installed, (older cars).

Step 8 - Most worn key problems will need a key ordered from the dealer using the vehicles VIN number.

Step 9 - Most vehicles with an automatic transmission utilize an interlock cable that prevents the transmission to be moved from the park position.

If the gear shift selector is not completely in park it can cause the ignition switch to jam due to interlock misalignment. To fix simply move the gear shifter from park to drive then back into park again.
