During the last couple of weeks, my '99 RX has developed a short ( 2-3 seconds) delay in the "beep" when I lock it with the Fob. And sometimes there's no delay at all, i.e. normal operation. Anybody ever had this happen, and/or know the cause?

 

 

It happens to my 00, but not the delay in beeping; it is the delay in locking. Pressed the lock button, 2 - 3 seconds later it locks with a beep. Unlock also has some delay.
