I pre-wired the 202U receiver on my test bench, programmed the unit for momentary use as a key less entry unit for my vehicle. I then installed the unit, made the final connection as needed, everything worked great. No problems for a few weeks and then last night I noticed that the doors would not lock or unlock. There was power to the receiver but when I press the remote buttons the relays will not operate(lock or unlock). I also was not able to put the reveiver into program mode, or code delete mode. Please advise how I should proceed
Sorry for the trouble,
Would you please first try another dedicated power adapter (12Vdc) to power our receiver & try again?
Most issues have something to do with power.
