Remote key not working - no light when pressed

[Cliveski]

I think I may have a problem with my actual remote key fob.

Key works fine to start the car or unlock the door manually but the remote doesn't do anything - I have changed batteries but the little red light on the fob never lights up.

Can anyone suggest what might be the problem and how I go about fixing it?

I have tried re-programming the key in the lock but nothing happened - no horn sound or flashing indicatorsl.

Sadly I don't have any of the key codes, just two keys (1 normal and 1 remote).

Should help, but it does sound like you radio part is faulty. Double check the battery though with another new bat not from the same pack.

Thanks Reflex88 - I had read that post previously - but prior to your final post, having read your final post it makes more sense and I imagine I need a new radio remote.

Got a used remote key off ebay and used the top of that key (where the buttons and transponder electricals are) with the bottom of my own remote key (where the blade and immobiliser chip are). I then did the key coding proceedure but the horn never sounded / lights never flashed - thought it hadn't worked but when I took the other key out of the ignition and locked the car with it I was then able to use my 'new' key to unlock the car by remote. Only cost me £3.50 so well pleased. Just need to make sure you buy a key with the same frequency (mine was 434mhz) as written on the side of the top part of the key.
