E-ZPass Maryland Transponder Replacement Program

What is the transponder replacement/swap program?

Each E-ZPass Maryland transponder has a non-replaceable battery with a limited lifespan. As a result, we have initiated a Transponder Replacement Program to help ensure uninterrupted service.

E-ZPass Maryland customers who have beige interior transponders eight (8) years or older will be receiving new, FREE E-ZPass transponders in the mail. You will receive your new replacement E-ZPass device along with mounting instructions and directions on how to properly dispose of the old transponder. It is important to remove the old transponder and replace it with the new one as soon as it arrives.

There’s no action needed by you except to verify that the address associated with your account is the mailing address where you wish to receive your replacement transponder. If the address is incorrect, please update it immediately by logging into your account, or by calling our Customer Call Center at 1-888-321-6824.

If you are in need of immediate replacement, please visit one of our customer service centers. 

Transponders that look like the device in the image on the left are eligible for a free replacement. 

To test the battery in your E-ZPass transponder (this includes interior standard, license plate mount and FLEX models/devices), please visit a customer service center. 

Note: If you have a non-standard device (this may include a license plate mounted transponder or a FLEX transponder) that has reached the end of its lifespan, you must purchase a replacement OR switch to a standard transponder free of charge. To do so, contact DriveEzMD.
