Do you have another fob where everything works when you press the unlock/lock buttons?
Just to cover the basics our fobs take two batteries you stack them (2) 2025 batteries.
Do the locking buttons on the console lock and unlock the doors?
Can you lock the doors drivers and passengers by using the lock on the drivers door by turning the key clock wise?
Any detail you can give will help.
Please let us know what you find.
