I replace the window switch for my 2006 Honda Accord and now both car key fob wont work. I have tried to re-program the keys, still not working. Any ideas on how to fix this will be most appreciated.

I had the same problem with my 2005 Honda Accord Coupe EX. I had both the master power window motor replaced AND the passenger side power switch. Sit in the driver seat, open and close the driver door, then manually lock and unlock each door. Meaning actually push each lock button down and pull back up (I have a 2- door.) Then repeat. Put key in ignition and turn on to "II" ( this is where your dash lights should come on but not the engine), immediately press the lock button on the fob, then turn off (to the 0). Do it again, repeating this four times, on the fourth time press the lock button TWICE then turn to the off position (O) and take the key out. At this point the Fob should work. Mine did!

I also have a 05 accord coupe but mine is a lx i cant get this to work, is there a sequence or timing you used to get the results you got?

I have a 04 Honda Accord ex I ordered a new Master switch and same thing happened after 50 times of doing it I sent it back as it was one number off what came from the factory How ever I put the factory number in and it says not for a ex I'm at a loss here

Having the same problem now. will try mine tomorrow, hopefully it will work

I have tried and It didn't work. I don't even undertand what the word fob stands for

Had the same problem. The 3rd answer provided by Mat worked for me. You need to have your old switch: https://www.cargurus.com/Cars/Discussion-t19484_ds555817
