I am trying to get into my Hyundai. Elantra I have lost the key fob and if I use the key it will set off the alarm please advise

you can get the key to override alarm by just turning key to ON position and leave it that way for 1-3 minutes alarm will slow down and beep a few times then silent. turn key off wait 5 seconds then start engine

You can purchase a key fob from your dealer and they will have to program it to your car. The security system can be disconnected but it is not advised.

You have screwed it up so bad that it needs to be taken to a dealer and reset.

their is no doubt some way to reset it by turning the key so many times left and right ?? but try this ,and that put key in drivers side lock and lock and open three times slowly then open door on last attempt and try to start within 15 secs of opening the door lock ,also try the spare key in case the chip has fallen out of the key ??

There is NO kill switch on the 2000 Elantra... HOWEVER, there is a thing called the Key Fob (keyless remote entry system). There is, however, a system in place called the 'starter kill' circuit and it is activated when the burglar alarm goes off.... it's called the burglar alarm relay and it is activated to prevent the engine starter system from being used. There are three ways to get the engine started in such a circumstance... 1. use the key fob to 'disarm' the system... 2. put the key in the ignition and turn it to the 'RUN" position and wait until the alarm stops (horn stops beeping and the parking lights stop flashing), then the engine will start.... 3. pull the starter relay from the UnderHood junction box and bypass the starter circuit (key in ignition and in the 'RUN' position), jumper the starter solenoid circuit to energize the solenoid to start cranking the engine -- it should start then.

you could pull one of battery terminals off for just a second that should stop the alarm from going off

change the battery's in the key fob

<Have heard that putting key into ignition in 'on' position and waiting sixty seconds for alarm to go off, then turning key off and back on will disable alarm. Haven't tried it yet.>

rweh is correct! Thank you! It worked for me!
