I recently purchased a used legacy and I am now noticing that I cannot lock my car from the inside or outside of my car. I have to manually push each lock button on every single door. I can unlock it with my key, the automatic unlock, and the one on my door. The problem is I cannot actually lock it, if I click the lock button on my key or on my door it makes a noise as if it is trying to lock but it doesn't actually lock. any suggestions?!
