Hello and welcome to justanswer.com
The alarm shold not go off as long as you unlock it with the key. If the alarm goes off just relock the vehicle with the key.
Will i still need to go the dealer to the the keyfob reset???
No you can reprogram the fobs yourself. If they do not program then you will need to check the battery and/or replace the fob.
When carrying out the alarm remote programming, ensure that no other vehicles within a 50 meter radius are undergoing the same programming procedure, as this could affect the programming operation.
Note :All required remote transmitters must be available when carrying out this procedure.
