Today when l try to unlock my hundai tiburan 2003 with the radiobutton key, it wouldnt unlock or lock the car. So l had to use the actual car key which caused the car to act funny and they horn turned on and it dont turn off till l get out the car and lock it back from the outside with the actual key!!!! The car starts but the horn is still going off and wont stop at all. The radiobutton key dont work at all also! l unhocked the battery, then the horn and nothing worked! Im a women and l dont got much experience in cars, please have that in mind! l hope you can help me out!!!!!!!!!!
First of all l wanna say thank you! But yes l got a new battery for it! l just bought it a month ago, because it didnt work at all.
And like l said l have no clue where and how to disable the alarm! ;(

First thing to check is the battery in the remote. The remotes r pretty durable & seldom fail, but they battery must be replaced occasionally. If the key does not disable the alarm, it is likely & after-market alarm & if so there is usually a disable switch for just this sort of occasion. It is usually small & in an inconspicuous place for obvious reasons. If u can find the switch, u will normally need to turn the key in the ignition to the ''on'' position & then activate the switch (usually a very small button or very small toggle switch located somewhere under the dash) This will disable the alarm & allow u to drive the car until u can correct the problem.
