rear door latch

My 2004 Honda Element driver's side rear door is stuck closed. It gives from the top of the door, but the bottom is firmly stuck in place and will not open via interior or exterior door handle. Have you heard of this and do you know a solution? Honda dealer wants $125 just to look at it.

The right rear door has not been closing properly,I found the latch on the bottom of suicide door to be completely loose.I tried to tighten it but it is spinning.There must have been something underneath it for it to screw into but I cannot see anything.I removed the trim panels from the rocker...
