utilize Apple CarPlay efficiently and dashboards equipped with stylish accessories have undoubtedly simplified our lives, yet technology can also become problematic in certain circumstances. For example, a mechanical key can unlock and start a vehicle without any batteries. However, if your smart key fails, you might find yourself stranded — until you discover how to operate it even without a mobile phone.

Much like Bluetooth, this means you must be within a detectable distance for your vehicle to process your smart key instructions. Some models allow you to unlock them merely by touching the door handle with the key nearby. While these conveniences are helpful, what should you do when the battery in your smart key fob unexpectedly runs out? Fortunately, several backup options exist in case this predicament arises.
