What Is a Smart Car Key?

A smart car key, also known as a keyless entry remote or proximity key, uses encrypted radio signals to communicate with your vehicle’s onboard computer when you near the car. This allows you to lock/unlock doors and start the engine—all without inserting a key. The technology improves convenience and theft protection, but when the smart key stops working, replacement and reprogramming must be done by a professional locksmith using specialized diagnostic tools.

When You Might Need Smart Key Service

You may notice problems like:

• The vehicle no longer detects your smart key
• “Key Not Detected” or “Key System Error” messages appear
• Buttons on the remote stop responding or are worn out
