Computer problem
2007 Lexus IS 250 6 cyl 86000 miles

When I normally walk up to my car with my keyfob, the door automatically opens. But lately when I walk up to the driver's side, it doesn't automatically open.I always have to manually open the door with the keyfob. Also when I want to close the door by pressing the lock button on the car door. It does nothing-I have to use the keyfob to close it.

What can I do to fix this?

Thanks so much!
