The doors don't lock?
Any of them <img src="/forums/images/graemlins/confused.gif" alt="" />
DO they lock manually?Can you push the lock down on the doors,and lock them.......
Can you unlock/lock them with the key from outside the vehicle?

If they all won't lock,together or individually,electrically or manually then each one is broken,I doubt this is the case,

so,

Be more specific with the problem and try not to ask a 'billion questions in a single post.

As for the shocks,the ones you picked will be fine,
Removal is pretty straight forward,remove the tire,put a jackstand under the Rodeo and remove the bolts one on top one on the bottom,Sometimes the top one will spin the shaft as you try to remove the nut,if it does use vise grips on the shaft of the old shock to hold it fron turning.(do not do this with new shock).

Bottom bolt is about the same,take off the nut and tap bolt out,it will help if you put a jack under the lower a-arm to take the wieght off the bolt.....use anti-seize on the bolt when you put it back together..........

good luck
off to the garage~~~~~~~~~~~~~
