    This is a helpful guide. Most of us forget how vulnerable we can be if the battery dies and we don’t know how to use a FOB properly.

    I know people who have spent upwards of a $100 simply because they did not have a guide like this.

    The more important thing is what to do once you are inside the car. Our suggestion is to ALWAYS be prepared for a new battery. While poor circuits can cause issue, the most likely issue is always an old battery that has gone through it’s life.

    If you have had your car for more than 5 years, it might also be a good time to change your FOB battery. It can last up to 8-10 years, but again, you don’t want to be in a situation where the FOB stops working.
