In the modern world, key fobs have become an essential component for vehicle access and security. These small remote controls not only enhance convenience but also add a layer of protection against unauthorized entry. However, like any electronic device, key fobs are susceptible to wear and tear, damage, or even loss. This article delves into the intricacies of key fob replacement, detailing the types, costs, and common questions surrounding this need.

| Standard Fob | Remote keyless entry fobs that control locks and alarms | Unlocking doors and trunk access |
| Smart Fob | Advanced fobs with additional features and keyless entry | Push-button start and proximity unlocking |
| Transponder Key | A cutting-edge fob that contains a chip for starting vehicles | Vehicle start authorization |
