SOURCE: key fob for hyundai elantra not working

Please dont worry yourself so much the security locks needs to be reprogrammed to enable it work effectively. Same happens to other vehicles as well.

Consult Hyundai garage close to you or if you have it in your manual.

Good luck.

rate this.

SOURCE: my Porsche Key fob no longer unlocks the doors

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

SOURCE: WHEN I PUSH TO BUTTON TO UNLOCK MY 2007 HYUNDAI

the car has two codes one is fixed the other is a rolling code which changes each time you press the unlock button,the first is allowing you to unlock the car but when you open the door it thinks your trying to steal it and the alarm goes off,then when you put in key it is recognising the key and switching off the alarm....NOW if you follow the instructions in the book you can reset the alarm(as i worked for hyundai over 5 years ago i cant remember the sequence,sorry)

Car will not start


replace the battery in the key fob and unlock the car with that, if u last locked the car with the key fob, you armed the alarm and can only be disabled by unlocking with the key fob, the car wont start because its an anti theft feature.
