I cannot lock my truck anymore, Key works fine in ignition but doesn’t turn on the driver side keyhole. Am i able to get a new barrel? or have to get a new door handle?

 

Got the barrel turning A tiny piece of my old key broke in the barrel. I drilled thru the top and drilled out the last locking pin and now it turns with the normal key. doesn’t work with a screw driver. so now that’s fixed. Now the door opener actuators piece of plastic snapped so it’ll go in the hole but it wont stay firmly in place. Now what? What can I do to get it locking?
