Many modern high-security systems and manufacturers have made the switch to transponder keys for extra security, but how exactly do they work? While it may seem like wizardry, it’s actually good programming. These common questions can give you some insight into how they work.

A Brief Introduction to Transponder Keys

How do they work?

These keys are programmed for the specific product they come with. They’re equipped with a small microchip that emits a low-level signal called radio frequency identification. Your system will only start operating after the remote receiver recognizes your key’s unique serial number. 

Where can they be used?

Most cars manufactured after 1995 have utilized transponder keys, programming them to communicate with the vehicle’s transmission while you have the key in the ignition. Other keyless entry systems like residential and commercial security alarms, gates, and garage doors also use transponder technology.  

What are the benefits of having a transponder key?

This type of key can provide you with an extra layer of security. Your entry system won’t open if it can’t detect your key’s digital identification or microchip. A transponder’s hardware also makes it impossible for intruders to hot-wire your car.

Can they be replaced?

The key’s unique signature has to be programmed to respond to your remote receiver, so professional-grade equipment like a clone key programmer is required to duplicate one. Many locksmiths have this machinery on hand, so they can program the new microchip to give you access to your vehicle again.
