Hi hope someone can help, i recently bought off
a r reg megane with a faullty gear box, when I viewed the car the guy started it for me and the engine sounded sweet and i bought it.
after doing all the work to the car, new gear box clutch starter battery engine mounts etc etc I found that the car wouldnt start or operate the central locking, the key looked a bit naff button wise so I ordered one off
only to use the plastic parts I also resoldered the led back onto the board built it all up and tried it on the car at first it wouldn't work and then suddenly it did it locked and unlocked the car several times and then ,,,,,,stopped I then sussed that it had the wrong battery installed one fat one instead of 2 slim 2016's so i placed in 2 new batteries thinking that this would cure it as it was obvious the ir remote is 6v and still it wont operate the doors.
I have tested the key looking through my mobile phone and i can see 2 purple blips come out of it when i press the button.
I have looked at the circuit board for the ir reciever and it looks perfect no corosion or dry terminals
so the question I like to ask you guys is ,,,can anyone point me in the right direction to fix this problem
