Key remote stops working?

[jscrimsh]

The remote in my key seems to have failed to a certain degree. I put in a new battery last March when I first got the car. The rear trunk opener still works fine, but the door locks will not lock/unlock. In watching the receiver on the dash, I see it receive the signal from the trunk opener, but nothing seems to be received from the locks.

Could the door lock button itself be going bad? The light on the key is lighting up, I just don't see the corresponding light on the dash flicker as it does when I pop the trunk.

Anyone else seen this issue?

Thanks!
