Does anyone have any suggestions to remedy this problem?

When I unlock the driver's door(using the remote), it's sometimes slow to respond. When this happens, I'm unable to unlock the rest of the doors, and once inside, none of the window buttons work.

This problem comes and goes. Any suggestions?

 

change the battery

 

I did. The old battery ran out a couple of weeks ago, so I've got a new one in. Hmm...I think I'll have to have this one checked out.

Thanks!
