Narrative:
During our takeoff climb to FL230; while accelerating from 280 to 320 KTS; the aileron lockout message appeared on the cockpit display screen. Prescribed QRH procedures were accomplished. We declared an emergency and returned to ZZZ for an immediate landing. I determined it was better to land in an overweight condition than to continue flight to burn down fuel with a known flight control problem. The touchdown was at less than 300 FPM rate of sink. The auto brakes failed during touchdown; but the aircraft was slowed with reverse thrust and minimal braking. The event concluded without further incident.
