Just thought you might have opened up the key & dropped the chip from inside.  Are you using the same key as you usually use? If you have a 'favourite'/prefered key, try using that one.

i have used both keys & tryed to reprogram them by turn on then waiting 30 seconds & then pressing lock/ unlock one at a time still no luck

You're only resetting the central locking by doing that. It's the chip in the key that's taliking to the alarm ECU that you need worry about.

you need someone far more experienced in the electrics/imobilisers/etc than me.
Where in the country are you? There may be very well someone local to you  ....
