What Is a Smart Car Key?

A smart car key—sometimes called a proximity key or keyless entry remote—is a small electronic fob that uses encrypted radio communication to connect to your vehicle. When the key is nearby, your car recognizes it, unlocking doors automatically and allowing push-button start. This level of convenience is highly advanced, so replacement requires specialized programming tools that only trained locksmiths can provide.

When You Might Need Smart Key Service

You may need expert assistance if:

• Your car displays “Key Not Detected” or “Key Error”
• The fob won’t unlock or start the car
• Buttons are worn, cracked, or unresponsive
• The remote was lost or stolen
• You want a second key programmed for backup
