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.
B737 Captain reported that an improper maintenance procedure resulted in both thrust reversers failing to deploy on landing.
