hornet auto start every day, 476t remote

Previous owner installed a Hornet alarm on my 2003 H2. It has the 476T remote - I don't know which alarm model it is. The remote is a 4 button: lock, unlock, AUX and horn(panic). Suddenly it auto starts every day at 1:30. I looked thru many of the manuals online and it looks like the lock and horn buttons pushed once simultaneously put it in this mode to auto start every 24 hours. None of these manuals addresses how to take it out of this mode. I read a similar post "hornet 564t random auto starts" and the solution was to push the * key on the side of remote - mine doesn't have this key. My model will remotely start (once) when the H2 when the lock & unlock buttons are simultaneously pushed. I tried simultaneously pushing the unlock and horn button - it still auto starts. Originally the siren would activate when it would auto start on the 24 hr timer. I pushed some other combos & now my siren doesn't beep when I arm and disarm (I'd like that back too) but the siren no longer wails when it 24 hr auto starts (so that's better for my neighbors, I guess). Can anyone get me outta this mess? I gotta go to the airport this week & I'd really rather my car didn't start while I was away! :(

umm, i can't remember off hand how to eleminate the 24hour start, i'll check it tomorow when i get to work if no one else replies, th part with the siren not sounding, with the car off check to see if the red led is on steadily, not flashing if it is on solid the alarm is in valet mode, simply find the valet switch, turn the key to ignition position turn it back off and then tap the valet button once, or you can open a door and hit the lock, aux, lock again in that exact order, post u tommorow on the timer mode.commit your way to jehovah and he will act in your behalf. psalms 37:5

ok - just checked The light typically strobes when the alarm is armed. Now the light is not flashing & is not even on (but I checked and the H2 was locked). Wonder if the alarm is no longer arming? The lock and unlock work. The lights flash twice when I unlock and once when I lock.

You were right. I was in valet mode. Last night the LED was not on (but I checked when alarm was supposed to be armed). Today, when I got in - LED was solid before I started the car. I turned it off my turning key to ign then off again & tapping valet switch (didn't know I had one - its in a sneaky spot alright). Now chirp is working to arm & disarm. When I arm, LED is flashing in a pattern of 3 quick flashes. That's new. It always flashed on/off like once per second. Does this mean the daily auto-start will discontinue?

i'm not sure, it's been a while since i installed that system, if it still continues, the next time it starts at 1:30 tommorow, step on the brake pedal when it does that should do the trick, i can't seem to access a manual at work.commit your way to jehovah and he will act in your behalf. psalms 37:5

It did auto start today - I forgot about the time change (2:30 now). Tomorrow, I'll try the brake then wait to see what happens on Wed.

pressing the brake will only stop the car that one time, it will not solve your problem. go to DEIs web site and look for a hornet alarm with that same feature and a similar keypad then look and the install manual PDF it should tell you how to turn off the feature. even though it might not be the exact same alarm as yours my guess is DEI doesn't change the way their features work very often. just try it

Stepping on the brake shut down the engine just that one time, but it still auto started again today -- just like "soundnsecurity" said above. I have gone to Direct's website, downloaded and read thru about 20 owners manuals. The 554T model seems to address much of the stuff I have - and tells you how to enter the 24 hour timer remote start mode (press lock and horn simultaneously) -- But nowhere do any of them tell you how to disarm unless you have a * key. I don't. Someone must know how to disarm this 24 hour remote start! Help - please. I'm about to take a hammer@myHUMMER!

have you tried calling DEI tech support? what button are you using to remote start your car normally? this should be equivalent to the * key. its very hard to help because it seems that the remote you have is not the remote that originally came with the alarm. whenever you program non stock remotes to an alarm there is the chance that the buttons can be different. it all depends on how the alarm is set up to read the remote signal. are there any buttons on your remote that just dont seem to do anything? this is evidence that your remote might not be 100% compatible with whatever alarm is under your dash, meaning it might arm and disarm but some functions might be lost. my best advice to you is do your best to look under your dash and try to find the brain. if the installer did his job it wont be easy but if you say you know where the valet switch is just trace those wires coming from the switch straight to the brain. the model number will be on either the top or bottom cover. as for your trip, if you want to disable the remote start temporarily try to find the hoodpin that should have been installed under the hood around the edge somewhere, it should be a kind of yellowish color but might be rusty by now but once you find it unhook the wire from the bottom. it should be a gray wire if the alarm is DEI but once you have this wire hook it to the NEGATIVE pole of the battery or any metal part of the frame. this will make the alarm think that the hood is open and will override any command to remote start. sorry i cant solve your problem but i hope this helps

Hey man, i have the same model as you and i was wondering, could i get that manual from you? or could you shoot me over a website with it. Ive been looking everywhere for SOMEONE to have this and i could find anyone, then i saw you and had to join this website. But do you have that manual>? thanks alot
