SimHub’s Keyboard Emulator and DRE send inputs to the simulator through separate routes. The setup below uses iRacing as an example.
In the sim
In iRacing, open Settings → Keybinds → In Car → Cockpit and assign Enter/Exit/Tow Car to Shift+R for this example. Save the intended controls profile using Save or Apply & Close.

DRE
With DRE connected to iRacing, open Controls → Sim and find Enter/Exit/Tow Car.
Check that the read-only iRacing Binding column on the right shows the saved Shift+R assignment. Check the smaller Profile: name label beneath the header too.
You do not need to enter Shift+R in DRE. Optionally assign a controller button in Controls → Sim if you want that button to request the action through DRE. Voice requests use the same saved iRacing binding.
DRE still needs a supported keyboard output assignment in iRacing for this action; it cannot emulate an iRacing controller-only assignment. If the profile label or output is not what you expect, save the intended iRacing profile again and check DRE. Selecting without a detected save is not a guaranteed refresh.
If DRE shows an unassigned, controller-only, unsupported or error state, resolve the issue it explains. DRE sends no guessed replacement key. See How do I map controls? for details.
SimHub
- Output Mapping -> Assign Roles: Add Enter/Exit/Tow Car as a new button
- Map the Enter/Exit/Tow Car to your wheel buttons
- Go to Controls and events -> Keyboard Emulation and click Add mapping
Under Input, click Click to configure and Simulate press the role: Enter/Exit/Tow Car (You can use the SimHub smartphone website to trigger it). Press Save.- On the right at Simulated Keys, press the field Click to assign and press Shift+R

SimHub’s simulated keys must match the keyboard assignment in iRacing. In this example, SimHub sends Shift+R directly to iRacing. If you change that assignment in iRacing, update the SimHub Keyboard Emulation mapping too.
DRE reads Shift+R separately from the saved iRacing controls profile and does not configure SimHub for you.


Under Input, click Click to configure and Simulate press the role: Enter/Exit/Tow Car (You can use the SimHub smartphone website to trigger it). Press Save.
