tailgate lock problem

Hi Guys
My tailgate lock motor is knacked. How do I open the door.I've got the rear trim off and all and can see the motor. I've heard that you can release the lock by using a tent peg .Where do I position it and do I take out the bottom screw holding it ? any help appreciated

Hi all

Just to let you all know I've done the job. Disconect the electrical conection. Remove the torx screws from motor which holds the black plastic cover. Pull the bottom of the plastic cover like mad. It wont break just bends. Hold the cover away from motor. I used a screwdriver. Get a small mirror and position it between the plastic cover and the motor so you can look up and see where the release lever is. Its about 3-4 inches up on the left of the motor. I cut a scewer down to make a hook. Remove mirror and holding away the cover slide the hook in and up and pull.I thought it was going to be a mare but I got it on the 2nd try. Renewed catch solinoid job done.
