Water damage (electronics and water don’t mix) or real chip breakdown as a result of the fob falling or being crushed are the usual causes of this.
Make sure you’re using the right key fob for the automobile before placing an order for a replacement key. Even though you and your spouse own the same brand of vehicle, her key fob could not function in yours.
