Hi friends,my car doesn't locks by remote it self when i press the remote it just locks and unlocks it self that only for two times,

2nd thing is when i lock car with key then all the doors gets locked except the left rear door,same with unlocking all doors unlock except rear left door while unlocking with key the main drivers door 

Expecting some genuine solution

Thank you

My car is subaru b4 rsk 2001
