What exactly is the difference between synchronous readkey and asynchronous?
Are you trying to read keys from the keyboard?

Normally I would use a timer. Set it´s interval property to the
desired delay, set it's execute event to point to a method and set
it's Enable to True when needed.
On the execute method would be something like:
MyTimer. Enabled := False;
// Code to be executed
but I think this requires Lazarus LCL to be used.
If you want something to execute without halting the main program and
can't use a Timer component, then you really should think about using
a separate Thread from this.
