Keyless entry issue (2010)
 

I purchases a 2010 Elantra a little over a year ago andit has worked flawlessly until today. This is minor but...

My keyless entry used to honk the horn when I pressed the remote lock twice, but now it no longer honks (although it still locks the car). The horn still works. I don't know whee to look. Could this be a fuse?

Do the lights flash when you lock the doors?

I solved then problem - my hood was unlatched. I read elsewhere this function is actually a securityalarm of sorts and will not chirp if a door, hood, or trunk is not secured. I reread my oweners manual and there is no discussion of this features which seems dumb since it is useful and helpful if understood. Thank you for replying.

Actually, it is clearly listed. Try reading your manual again:
