Check keyless after replacing batteries

Hi this is Dusty, I'm one of the auto experts on RepairPal's Car Genius team. That sounds like a simple but frustrating issue for sure, but accidentally reversing the polarity (positive and negative) of the battery during installation is a common occurrence (we've all done it at some point lol) The bad news is that doing so will keep the fob/remote from functioning as intended, the good news is that correcting it is simple. Ensure that the batteries are inserted correctly, there's usually an indicator to guide you in the compartment or on the cover of the remote where the batteries go. If they're in correctly, you may have received a defective battery. Be sure to use high quality batteries from a reputable source. If you have any questions, give us a call at (877) 913-1554
