A Key Fob has become an essential part of modern car ownership, offering both security and convenience. This comprehensive guide will delve into the intricacies of a key fob, exploring its functionality, technology, maintenance, and evolution.

Key fobs utilize radio waves to communicate with your vehicle. Earlier models used a fixed code system, which was vulnerable to code grabbing.

Keyless entry systems utilize proximity sensors, allowing you to unlock and start your car without even pressing a button.

Another indicator could be inconsistent functionality, such as the lock or unlock buttons working intermittently.
