Door mechanism

The bar on the drivers side door mech from the mech to the key hole keeps dropping off it looks like there should be a plastic grommit to keep the bar in place? dont suppose these grommits are available? any ideas what i could use to secure the bar? i thought about using a glue gun, ive only got 1 fob so if anything goes wrong with that i could end up being locked out.

doubt you'd get a grommit, could try a scrap yard or like you say, glue gun and maybe a small rawlplug cut down???

rawl plug? now thats a thought
