Patio Door Info. Needed

Hi I need some help. I have a certainteed sliding door that has a broken lock. Last year I had a keyed lock installed on it and it worked beautifully for about a year. Just recently, the key broke in the lock. I thought I just needed to replace the lock but found that the pin that actually latches broke as well. So, I need to replace the locking mechanism in the door first and then install the locking handle. However, I dont have any idea what part I need and how to do it. Here is the information on the sash of the door. Perhaps this will enable you to help me? Darn, its not letting me attach a photo. okay. Here it is 630R0626.20 B2 W95 1/2 X 79 1/2 F 47 1/4 X 74 11/16 ***************** XTPD Left sash.1 STD sash set 171528-21 2STD OX - sng slid C1 ************* WHI 61988300000000001 6/26/06 Please let me know what part ( parts) I need. And if you can tell me... do I hire a locksmith? Thanks! Elizabeth

They put your outside pull on backwards. It looks like you are missing a couple of screws also. The 82-310 will probably need to be shortened. Use the old one as a guide. I use 2 sets of locking pliers to bend until it breaks. Don't listen to anyone who tells you to use a hacksaw. The hardened metal is very resistant to cutting, but breaks easily with a few bends.
