Dear customer, before point out to a problem with the Sam module, I would like to know if you have tried with a spare key and also if the key that currently has the problem you have tried to code it with a key programmer.

Dear customer, I am going to recommend first of all to do a configuration again from the key, reconfigure your key with the vehicle to factory data, also I am going to tell you to be aware as there is a possibility of replacing the key for a new one.

The Sam module is in the trunk that would be the second step to check, precisely there is a fuse which is good to check before proceeding to disassemble the Sam module to be taken to review.
