Narrative:
We departed on a normal operation flight with no mels. Upon landing in ZZZ we had a dual thrust reverser failure. Both amber rev indications on engine instruments; master caution and amber reverser lights on the overhead panel illuminated. The aircraft came to a stop without incident. We contacted maintenance in ZZZ to come and have a look at the problem. The mechanic reported that the reversers were deactivated from a control module that controls the reversers; during a maintenance check conducted the night prior; and were never reactivated.there were no indications in the cockpit that indicated the reversers were not functioning. This would have been an issue with the takeoff and landing data; especially on a contaminated runway. Especially on a short runway.
