Your editor will HAVE to re-encode if you want the trims at spots that aren't at already existing keyframes. There is no way around this.
But, if he/she knows what they're doing, and depending on the source format, any re-encoding should continue to look very close to the original. For WMV encodings, for example, the encoder will do a stream copy when it can, creating new keyframes only when necessary. This results in virtually no generational loss because the encoder is simply moving already-compressed frames from input to output.
For this to work the encoding settings must be identical. A good editor will have the tools to reconstruct the encoding profile from the finished work, but it doesn't hurt if you can provide the settings used to make the originals, if you have them.
As Loch says, if you have the masters, you can always re-encode from them, but that's also the most time consuming.
