try synchronising the key fob as follows:
press the unlock button once
manually lock the car with the key
within 60 seconds unlock the car with key
if that doesn't work then try resetting the car by disconnecting the battery cables and clamping them together for 10 mins. Remove both battery leads from the battery then use a nut and bolt or G-clamp to hold both battery lead terminals together.
This discharges any capacitors / memory within the ECU and around the car so ensures all memory settings are wiped clear - back to the factory default.
This will reset all the systems on the car and you may need the radio security code to get it going again, and ensure that the keys are in your hand when you re-connect the battery as the car may lock and turn on the alarm
if the 1st 2 things don't work then sorry to say yes the car will need to go to the dealer
Sorry but no
the dealer will need the car and the keys all together to do the coding
it might be worth calling them to ask but I'm about 90% sure that they will need the car
do you still need help?
