Strange keyless entry problem (2006 Sonata)
 

Until today when I pressed the lock button on the keyless entry remote
the lights would flash so that I knew the doors had actually locked. As
of today I no longer get the flash though the doors do lock.
Additionally, if I pressed it again while it was locked the car would
beep. This is no longer happening either. Any ideas? It's a 2006 GL.
