SSM 51122 2017-2022 F-250-F-550, 2015-2020 F-150 And 2018-2022 Expedition - Lock Cylinder Unable To Turn To Accessory Position

Some 2017-2022 F-250-F-550, 2015-2020 F-150 and 2018-2022 Expedition vehicles without push button start and passive entry may exhibit a condition where it is difficult to insert the ignition key and/or turn it to the accessory position when removing the ignition lock cylinder per the functional lock cylinder service procedure in Workshop Manual (WSM), Section 501-14. This may be due to debris or contamination in the ignition lock cylinder. If this concern occurs, use a suitable shop vacuum to dislodge or remove debris or contamination by placing the vacuum hose over the lock cylinder, without the key installed, for 30 seconds. Insert the ignition key and reattempt turning it to the accessory position for lock cylinder removal. If the key will not turn to the accessory position, continue with the non-functional lock cylinder removal procedure.
