Anybody have a trick on putting them back on besides smacking them, lol.

I have taken the off dozens of times and I am sure the retainer clips are probably bad, any idea on where to get new ones?

 

I have not looked at the Cobalt trim pad fasteners but I do know GM uses a two piece fastener on some cars. When removed they come out in one piece. You have to separate the two pieces and place the base back into the door and the pin on the trim pad.

 

not on cobalts. they just pop back in. Ive taken mine off a dozen more times then you and unfortunately have to do it at least one more. no idea on where to get exact replacements thou. theres some that are close at any auto store (napa autozone checker ect)
