My door lock bar was floppy so I just replaced it on my Compass Ralley. I couldn't see any way of tightening it and put it down to wear and tear. If its the same then four screws on the inside hold the lock barrel and outer case in place no adhesive found on mine, I just undid the screws and it came away. Make sure you note which way it was fitted and leave one window open near the lock in case you do a ME. I put mine on back to front and couldn't unlock the b,,,,,dy door. had to cut one of the rubber window catches good job only one was on.
