I have a little problem

I disconnected my battery today as my battery tray was in wrong and had no clamp but is due for test so disconnected battery took it out sorted tray put it all back then when I re-connected the earth the alarm beeped
I also replaced batteries in fob as they were almost dead
Now when I unlock the car it's fine then when I re lock it te alarm goes off then it starts and runs right it's the standard Subaru alarm and immobiliser

I have to lock the car then wait for the alarm to go off itself

Any ideas ?
