Hello my name is ***** ***** thank you for your question.

Does the head lights turn on and brake lights work? Did you try to jump start the car?

Customer: replied 10 months ago.
the car works. I use the manual key to enter and the intelligent key "work" when in the slot. The issue is with the intelligent key opening doors, truck, locking the doors, and starting the car when it is not physically in the port

note: both fobs worked before the vacation now neither works
Expert:  Jay replied 10 months ago.

What is the battery number on the fob.. Yeah.. That is odd.. I have one thing I would like to try after you tell me the battery number.

Let me know.

Sony CR2032
Expert:  Jay replied 10 months ago.

Thank you.. That is the correct part number.

Lets try doing a hard reset on the car and see if it wakes up the system. Try disconnecting the negative battery cable for 15 mins. Then let me know if the remotes work.

Hi, that did not work. Any other ideas?
Expert:  Jay replied 10 months ago.

If that did not work, then all fuses would need to be checked with a test light and then remotes checked with a remote checker to verify that they are producing a signal
