Thank you for the advice again.
I have had it checked and there is a constant drain on the fob yes

When a button is pressed, for the split second it jumps up to 3+ but its always at 1.2 with no pressing etc.
I have been advised the only option for that is to have a new fob, gutted!
As for the 2nd fob, i have been advised it just seems that it isn't synced to my alarm to unlock or lock (no orange flashes etc or unlocking when press buttons but will still start and run the car).
Unfortunately the common re-sync doesn't seem to work with my fob (2 button) so i will need to take it to Chrysler to have that one sorted as well
Is the common sync:
Press button twice (lock or unlock)
Within 30 seconds insert key in to barrel and turn to 'on/run' and start the engine
Wait 30 seconds then try pressing the buttons again and hope for success?
Thanks again guys, your advice paid off and helped identify it is the fob with a constant drain
