Door Lock Cylinder Replacement
IF THE IMAGE IS TOO SMALL, click it.
In addition to removing all wear & damage, replacing the door lock cylinders with new has the added benefit (on pre-'96 trucks) of updating the keys to the later 8-cut style, which has more aftermarket support (like StratTec's Bolt line of accessories). I also allows matching the new keys to a new 8-cut ignition lock cylinder.
Part of 1980-1986 Ford Bronco Service Procedures
This is an eight-panel photo procedure ("DoorCylSwap") documenting the removal and replacement of a door lock cylinder on a brown Ford vehicle. Panel 1 shows the open door and its rear edge. Panel 2 shows a blue plastic trim tool being used at the door edge to release the cylinder retaining clip. Panel 3 shows the removed "cylinder clip," noting that its "catch tabs" get "bent back during removal." Panel 4 shows old and new cylinders side by side with orientation notes: "lever forward" and "wide boss down." Panel 5 shows the old cylinder withdrawn from the door. Panel 6 identifies the old cylinder as using a "10-cut key" with an "old-style plastic lever," and warns "do not drop pushrod" into the door cavity. Panel 7 shows the replacement, a Standard DL140T cylinder, with a "new-style steel lever" and an "8-cut key." Panel 8 shows the new cylinder installed with the clip seated at the door edge. A reader learns the clip location and removal method, the correct installation orientation, the pushrod caution, key-cut differences between old and new cylinders, and the specific replacement part number (Standard DL140T).
