Not really sure why you'd need to replace both switches, other than "if one
is bad, the other must be close". But with that mentality should't he be
replacing every switch in the house, assuming they're all about the same
age?

Also, no need to do one wire at a time -- just make sure you remember what
wire went where.

The traveler connections are in different locations on different brands.
The color coding if present varies also. The suggestion to change both at
the same time is just to keep it simple for the next DIY guy.

Actually it's more like a $5 switch :) It's a Decora style dimmer with
a rocker switch.

It wouldn't surprise me to find a loose connection in there. Some of
the electricians that did the work in my house were a bit careless.

Since it is a dimmer, I would check to see what the load is. The average
dimmer is rated for 600 watts, but a combo type with separate switch may
only be rated for 300 watts. If the load is acceptable then do as others
have said and shut the power off and replace the unit. When replacing, only
remove the wires from the dimmer. Do not take apart any other wires in the
box that are not connected to the dimmer.

Also, be aware of derating issues. Many dimmers rated at 600 Watts have
a derated value of 500 Watts for ganged installations.

This means, if the dimmer is installed in a location all by itself, or
if it is a ganged location where it is the ONLY dimmer, then the 600 Watt
rating applies. If it is in a ganged box with another dimmer, then it is
only rated for 500 Watts.
