what do you mean by getting harder? This has been happening over 1 to 2 weeks, I would estimate. It started with clicking the button to lock, but nothing happening. At first, a 2nd click would do the trick. Then it got to where I would have to click several times, but finally it would lock/unlock. ...

It seems like locking/unlocking the car (2007 Vibe, pretty standard model) with the keyfob is getting harder & harder. I've tried switching the fob battery, no difference. Door locks seem to operate fine with the switch at the door. Anything I can look into? Thanks in advance.
