Hi sifus!

Wanna ask whoever had experienced or know the way to disable the car manually when car remote malfunctioned/not usable.

Situation: Car security alarm was activated and out of sudden, car remote failed/dead. So have to use the car key to manually open the doors. Alarm triggered and don't how or where to off it.

It a Hyundai Matrix CBU unit and factory alarm system.

Thanks all!

Disconnect battery lo

How hard can it be?

Disconnect then how? Reconnect again and the alarm again go off again leh? Should have a trick to kautim it right?

no alarm reset button?..u start the engine, press the reset button, and it will disarm the alarm..

No button to press and can't even start the engine at all. Thats why came in here for helps. Hahahah!!

u see ur drive side dashboard...under dashboard..can u see the small key hole??

can open door, can start car but alarm still will alert.

only method are find the fuse box or disconnect the wire to the alarm box or open bonnet find the alarm wire to the battery


shits happen when remote battery flat

open door, find the alarm reset button.
put the key in the ignition, turn till on. not start.
press the reset button.
done.

now, drive to an accessory shop, either disable the alarm or replace it totally.

Did you even bother to read the manual? If it is a factory fitted alarm, it will be in the manual. If it was installed by local rep, then call local Hyundai for assistance. If the car is recon and the manual is missing, then pray that somebody in here can help you.

I wonder if anyone manage to locate the override button ? It's not stated in the manual. It's just the Turn ignition "ON" and press within 5 secs......damn , not a single clue where it's the button.

Is the button hidden ? or exposed ?

What about Honda City? 2007 Model

I had the same problem. how to reset the alarm? my unlock alarm key not working. last ride i can lock with alarm key. then, my brother open the door manually ( because long time didnt use alarm door due to lock not functioning automatically. have to lock manually each door 1 by 1 ) and the alarm sound. we cant disarm the alarm system using alarm key. and now the car still armed, cant start the engine. is there a way to reset it ? btw, we just change the battery of the key.
(sorry broken english).
