Is there a way to lock certain pages from being edited by anyone other then the admin?

I have built a WordPress site and theme and have several pages that I do not want editors to edit. However, there are other pages that I want them to have access to to edit. Is there a plugin or code that will lock certain pages from being edited by anyone other than the admin?

Have a look at the Members Plugin by Justin Tadlock.

It has a “content permissions” feature, that let’s you restrict posts and pages by user role.

Alternatively, if you wanted to implement this yourself, you could write a shortcode that redirects the user conditionally. And place that on pages you want to restrict.

Since there is an excellent and well written plugin for this job however, this is one of the few occasions where I’d recommend using an existing plugin over coding it yourself.
