A smart car key—also known as a keyless entry remote, proximity key, or push-to-start fob—is an advanced electronic key that allows you to unlock and start your vehicle without inserting a traditional key.

Instead of using a metal blade, the smart key communicates with your car’s onboard computer through encrypted radio signals. When the key is within range (usually in your pocket or bag), the vehicle recognizes it automatically—doors unlock with a touch, and the engine starts with the push of a button.

This technology provides push-button convenience but demands precision programming. Our locksmiths handle all smart-key services using professional equipment.
