Car sometimes unlocks remote then remote wont work and cant unlock the car manually as it sets the alarm off and immobilizes the car

Hello Flona Kelly,

It appears there is a FACTORY BULLETIN on this issue...
Generally available on the internet... (I recommend
(FREE: registration required at BBB Industries (below)))
2009 Tech Service BULLETIN 09-BE-026

Applies to all Hyundai models of the
- Genesis (BH & BK), Tiburon (GK), Sonata (NF), Tucson (JM), Entourage (EP) and the Elantra (HD),

09-BE-026 (, below)): It is one of the best 've ever seen... quite simply states the hood contact is "to light"... which triggers the car alarm and the situations you describe.

Specifies the PART REPLACEMENT of the rubber bumper
(pictured: PAD - Lid Switch, part number 92736-3A000
"replaces" the existing part 92736-2D000 ("shorty"))) .

This NEW part is 2.5mm deeper than the old one
(From in front of an open hood it is on the right side center edge).

Hope this helps!!

Disable hyundai getz alarm

To disable the alarm on a Hyundai Getz, you just need to bypass the hood switch. The alarm circuit thinks the hood is up and will not go into the Arm state.

The switch connects the single wire connected to it to ground when the hood is up.

So you can just connect a wire from the back of the switch to ground. You can fit a switch to enable/disable the alarm if you wish.

This is equivalent to just locking/unlocking the car manually with the key.

2004 hyundai sonata anti theft car alarm solution

Per my local dealership this problem has been identified by Hyundai and a service bulletin released. There is a plunger-type limit switch under the hood (passenger side front corner - easy to see) that isn't being depressed enough by a small rubber bumper attached to the underside of the hood. The fix is to replace the existing bumper with one that is slightly longer. The replacement part number is 92736-3M000 "Pad-Lid Switch". It cost me 80 cents with tax. Just pull the old one out and push the new one in.

I have a 2001 Hyundai Sonata. When I lock the doors using the remote the lights blink but the horn does not beep. Is this a programming issue or is there something I can do to make it beep when I lock it...

Usually the HOOD SWITCH is the culprit. Check the hood for the hood switch button/depressor to be sure it's depressing the switch fully. If the hood is not properly adjusted, it can create this problem. Go to and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, illustrations, etc.

2003 hyundai santa alarm goes off by it self. had timing belt replace and left side axle boots.

sounds like the hood alarm switch is out of adustment,its located just inside the right side fender, probably was disurbed when the timing belt was replaced, it must make proper contact with the hood or the alarm will go off, usually in the middle of the night

Car alarm randomly goes off

there is a hood switch located at front passenger side under hood. check to make sure the plunger at hood is pushing the switch completely down. sometimes there may be just enough clearance that a strong wind will set the alarm off.

My alarm on my 2002 Hyundai Sonata keeps going off

Experience with this problem points to several possible causes. First, hood switch is improperly adjusted or rubber button on the underside of the hood which strikes this switch is missing or worn out (does the 'answer back' feature (horn toot) occur when you press the "lock" button on the keyless remote twice?). If it doesn't, this is the first place to look -- is the hood bent out of shape? Often I have found the hood adjustment is SO CLOSE to the hood switch being 'CLOSED', that a simple gust of WIND can set off the alarm.
Next, each door and the trunk have switches which must be in their proper positions (closed -- Open Circuit communication with the ETACS module) for the burglar alarm to SET Active/ON. The problem could be at any one of these switches, not to mention the ETACS module itself. Best solution:Take/tow the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.).

Theft alarm system

Check the alarm hood switch on the passenger side. Was the car in a accident ever? There should be a little rubber stopper that contacts the switch when the hood is closed. Either the rubber piece (attatched to the underside of the hood) is missing or the rubber is not contacting the switch.
