Alarm won't beep when doors are locked with key fob

When I exit my vehicle for the night, I always use the key fob to lock the doors and the horn would always beep as confirmation that I'd done this. This morning the horn did not do this and when I unlock the doors, now the lights won't flash like they usually do. Is there a way to reset this feature or have I blown a fuse of some sort?

    I have the same problem and it just started yesterday. The car locks and unlocks with the fob but the lights don't go off every time and the horn does not sound when locking. Any solutions?

    Alarm stopped beeping when doors are locked with key fob I always use. Tried the spare fob same thing happened. I've had both fobs for four years since purchasing the car in 2010 and haven't replaced the batteries. Replaced the batteries in both fobs and alarm still won't beep when doors are locked. The alarm will beep on both fobs when the red "ER" alarm button is pressed. Lights still flash and no problem locking or unlocking the doors with either fob. Would like the sound back when locking the car. How do I do that?

Many remotes use a button-press sequence to arm or disarm the audible or visual alarm arming indication. Your owner's guide should contain the sequence needed if the remote is capable of change. I have set my Subaru's signal to flash the lights only; the horn-honking seems superfluous and is kind of annoying.
If your alarm is arming at all, the system fuse in the car is probably not blown. You can check the alarm pretty easy by thumping on the car or rocking it hard a few seconds after arming the system with the remote. Either the sound sensor or the motion detecting feature should respond to one of those disturbances.

My 2005 Jeep liberty horn blows for no reason last night at 3 am it went off and the only way i could get it to stop was disconnect batt

double posted. wow.
when it beeped, did you look in the display (RPM)
it tells you why?? the VFD or EVIC tells you why.? (rpm dial)
do you park with the alarm on , on the street or a garage?????
if in a garage park and turn alarm off. it does turn off the alarm.
did you bump the panic button?
eg its under your pillow?? LOL or the cat chewed it?
read your other post, it's got lots of answer there.
to find cause.
if the horns stays off, if alarm is off then its not the horn button.

as many will say. there are 4 things that run the horn.
button horn
door locks.
panic.(part of alarm but not totally)
on my car, i have most themn turned off, like the lamp flashings.
and the horn chirp is off on all my cars, all i get is the door lock click sounds, nice (neighbor friendly)
so turn all all that and see if the horn still fails.

that panic button can fail,
if mind did id pull the fob battery and then use FOB 2.
to see of the FOB fails.

your other post said driving
this one says, parked. 3am clue.

When I lock my 2011 Tuscon from the inside and then use my Key to unlock it it sometimes sets the horn off and takes for ever to get it to stop beeping. Any suggestions on what could be wrong?

thats normal when you use your key fob to open door it resets the alarm --when you use your key alone to unlock you have a few seconds to place key into ignition and turn on to turn off and reset alarm --the vehicle initially thinks the door was slimjimed

How do I get my alarm system to chirp instead of beep when it goes off or when I lock my doors with the remote entry key fob?

Check to see if your vehicle honks when you press the "lock" button on your key fob. Press the "lock" button multiple times in a row. Many devices won't beep unless you double-tap the button after locking. If the horn doesn't honk, but the lights flash, your chirp feature is probably disabled.

Use your keyless fob and ignition key to enable the audible chirp. The process varies considerably on different makes and models. You must usually consult your owner's manual, a dealership or the alarm manufacturer for the correct process.

How to turn off the pro alarm

I would start by replacing the FOB. Sounds to like the electronics inside it are bad. The only reason the horns would go off is if you hit the panic button. There is a slight chance the receiver is bad. But Fobs are cheaper to replace than the receivers. If you have two FOBs and they both react the same, then replace the receiver. Or just ditch the system. The keys (in the door locks) should still activate the alarm system.

If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.

If you lock your doors with the remote, you have to use the remote to unlock them or it set off the alarm. I don't know why the manufacturers designed it that way(kind of stupid)but it's programmed into the on board computer. You can't disable the alarm without creating a worse problem somewhere else.
