Locking issues
 

Hi there,
I have recently bought a jdm 94 wrx. It has been resprayed at some point and had the rear door handles smoothed in and poppers installed to pop the doors.
Ok so the problem is when I lock/unlock via alarm fob only the front doors unlock. Rears don't and if you reach through inside to unlock they still won't , the laches seem stuck in the locked position. Not really sure where to go with this issue , wondered if anyone had similar prob

it will be the poppers m8 or break in the wiring.
