Obviously make sure the battery is good and if that is not the issue the key may need to be reprogrammed.

When mine did this I replaced the battery and it the problem went away.

Do you know what the price might be to reprogram the smart key remote ?

RRocket

About $100 at the dealer...give or take.

How do you start the car now? With another smart key? Does it have a button for opening the trunk? The reason for asking is to find out if you have a "master" key. You will need the "Master" key for the dealer to program an additional (or new) key.

Yes my key has a button for the trunk but the button for the trunk is broken, and i just put the key in the ignition like a regular key and this is the only key i got when i bought the car.
