I ran into the same issue and resolved it by first resetting my Visual Studio keyboard mappings:

Tools > Options > Keyboard > Reset

Then going into the ReSharper options and applying the scheme:

Resharper > Options > Visual Studio Integration > Apply Scheme

Update:

For VS2017 onwards:

Tools > Options > Environment > Keyboard > Reset

For Resharper 2017.2:

Resharper > Options > Environment > Keyboard & Menus > Keyboard Shortcuts > Apply Scheme
