I've just bought a Rockshox Reba Team off the classifieds, and straight out of the box the pushlock wasn't locking out the fork at all. The fork seemed to compress ok and have no obvious damping/rebound issues so I didn't think there was anything to worry about.
After 2 rides though it has stopped reaching full compression - now typically getting about 40mm out of a 100mm fork.
What does it sound like the problem is?
